+
+== Evolution
+
+Sometimes, a change to Pkl is large enough that it makes sense to create a proposal for the change so that it can be discussed in detail and vetted.
+
+Pkl has a process for managing such designs in a repository called {uri-pkl-evolution}[Pkl Evolution].
+
+== Roadmap
+
+To discover what might be coming in future versions, reference the {uri-pkl-roadmap}[Pkl Roadmap] project on GitHub.
+
+The roadmap describes estimates.
+The Pkl team aims to cut a release in February, June, and October of each year.
+If an item is not complete by the release cutoff date, the roadmap item may be bumped to the next release.
+
+Additionally, as priorities change, it is possible that items can be moved around or backlogged.

+= Pkl Binary Encoding
+include::ROOT:partial$component-attributes.adoc[]
+include::partial$component-attributes.adoc[]
+
+Pkl values can be encoded into a binary format.
+This format is used for Pkl's non-JVM language bindings, for example, for its Go and Swift bindings.
+
+The binary format is uses link:{uri-messagepack}[MessagePack] encoding.
+
+== Primitives
+
+All Pkl primitives turn into their respective MessagePack primitive.
+
+|===
+|Pkl Type|MessagePack format
+
+|link:{uri-stdlib-Int}[Int]
+|link:{uri-messagepack-int}[int]
+
+|link:{uri-stdlib-Float}[Float]

+|link:{uri-messagepack-bool}[bool]
+
+|link:{uri-stdlib-Null}[Null]
+|link:{uri-messagepack-nil}[nil]
+|===
+
+NOTE: Pkl integers are encoded into the smallest int type that the number will fit into.
+For example, value `8` gets encoded as MessagePack `int8` format.
+
+== Non-primitives
+
+All non-primitive values are encoded as MessagePack arrays.
+The first slot of the array designates the value's type. The remaining slots have fixed meanings depending on the type.
+
+The array's length is the number of slots that are filled. For example, xref:{uri-stdlib-List}[List] is encoded as an MessagePack array with two elements.

+= Language Binding Specification
+
+:uri-pkl-go-github: https://github.com/apple/pkl-go
+:uri-pkl-swift-github: https://github.com/apple/pkl-swift
+
+Pkl can be embedded within any host application.
+The host application has access to low level controls.
+It is able to manage the lifecycle of evaluators, as well as provide custom modules and resources to Pkl.
+
+Currently, Pkl must be embedded as a child process, by shelling out to the CLI using the xref:pkl-cli:index.adoc#command-server[`pkl server`] command. In the future, a C library will also be provided.
+
+When embedded, communication between a host application and Pkl happens via message passing.
+The message passing specification can be found in xref:message-passing-api.adoc[].
+
+For examples of language bindings in practice, review the link:{uri-pkl-go-github}[pkl-go], or the link:{uri-pkl-swift-github}[pkl-swift] codebases.
+
+NOTE: Pkl's Java and Kotlin libraries binds to Pkl directly, and do not use message passing.
+
+== Features of a language binding
+
+A language binding for Pkl should generally have the following components:
+
+. A client that spawns `pkl server`, and talks to it using message passing.
+. A deserializer that turns xref:binary-encoding.adoc[pkl binary encoding] into a structure in the host language.
+. A code generator that transforms Pkl schemas into schemas written in the host language.
+  The code generator is mostly written in Pkl, with a lightweight executable that acts as the glue layer.
+  For examples of code generators, consult link:{uri-pkl-go-github}/tree/main/codegen[pkl-go] and link:{uri-pkl-swift-github}/tree/main/codegen[pkl-swift].
+
+== Sample flow
+
+Here is a sample flow for evaluating a module with the following contents:
+
+.\file:///path/to/myModule.pkl
+[source,{pkl}]
+----
+module MyModule
+
+theModules = import*("customfs:/*.pkl")

+
+. Client sends xref:message-passing-api.adoc#create-evaluator-request[Create Evaluator Request], including `customfs` as a custom module reader.

+      }
+    ]
+  }

+All messages are encoded in link:{uri-messagepack}[MessagePack], as an array with two elements.
+
+The first element of the array is a code that designates the message's type, encoded as an int.
+The second element of the array is the message body, encoded as a map.
+
+Messages are passed between the _client_ and the _server_.
+When hosting Pkl (for example, the Swift application when using pkl-swift), the _client_ is the host program and the _server_ is the entity that provides controls for interacting with Pkl.
+When implementing an xref:language-reference:index.adoc#external-readers[external reader], the _client_ is the external reader process and the _server_ is the Pkl evaluator.

+=== Response Message
+A message that is the response to a <<request-message>>.

+
+A fire-and-forget message where no response is expected.

+Allows to change default class and package names (derived from Pkl module names) in the generated code.
+
+When you need the generated class or package names to be different from the default names derived from the Pkl module names, you can define a rename mapping, where the key is the original Pkl module name prefix, and the value is its replacement.
+When you do, the generated code's `package` declarations, class names, as well as file locations, will be modified according to this mapping.
+
+The prefixes are replaced literally, which means that dots at the end are important.
+If you want to rename packages only, in most cases, you must ensure that you have an ending dot on both sides of a mapping (except for an empty mapping, if you use it), otherwise you may get unexpected results:
+
+----
+// Assuming the following arguments:
+--rename com.foo.=x  // Dot on the left only
+--rename org.bar=y.  // Dot on the right only
+--rename net.baz=z   // No dots

+"org.bar.baz" -> "y..baz"     // Double dot, invalid name
+"net.baz.qux" -> "z.qux"      // Looks okay, but...
+"net.bazqux"  -> "zqux"       // ...may cut the name in the middle.
+----
+
+When computing the appropriate target name, the longest matching prefix is used:
+
+----
+// Assuming the following arguments:
+--rename com.foo.Main=w.Main
+--rename com.foo.=x.
+--rename com.=y.
+--rename =z.
+

+com.foo.bar  -> x.bar

+org.foo.bar  -> z.org.foo.bar

+[[http-proxy]]
+== HTTP Proxying
+
+When making HTTP(s) requests, Pkl can possibly make use of an HTTP proxy.
+
+There are two values that determine proxy settings; the proxy address and list of noproxy rules.
+When determining proxy settings, Pkl will look at the following locations, in order of precedence (lowest to highest):
+
+1. OS settings (on macOS, Windows, and GNOME environments)
+2. <<settings-file,Settings file>>
+3. xref:language-reference:index.adoc#projects[PklProject file]
+4. `--http-proxy` and `--http-no-proxy` CLI flags
+
+[NOTE]
+====
+The proxy and noproxy values are individually set.
+For example, using the `--http-no-proxy` flag but not the `--http-proxy` flag will cause Pkl to look at the PklProject file, then the settings file, then system settings for the proxy address.
+
+One exception to this rule is that setting a proxy address will cause Pkl to ignore any noproxy values set at the OS level.
+====
+
+Pkl only supports HTTP proxies, so neither HTTPS nor SOCKS proxies are supported.
+Pkl does not support authentication with a proxy.
+
+When specifying a proxy address, it must have scheme `http`, and may not contain anything other than a host and port.
+
+=== Proxy exclusions
+
+Pkl can be configured to bypass the proxy for specific requests via a proxy exclusion rule (i.e. the `--http-no-proxy` flag).
+It may be provided either as a hostname, an IP address, or an IP range via https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation[CIDR notation].
+When determining whether a proxy should be excluded, hostnames do not get resolved to their IP address.
+For example, a request to `localhost` will not match `--http-no-proxy=127.0.0.1`.
+
+For individual hosts (not CIDRs), ports can be specified.
+When no port is specified for a given host, connections to all ports bypass the proxy.
+
+A hostname will match all of its subdomains.
+For example, `example.com` will match `foo.example.com`, and `bar.foo.example.com`, but not `fooexample.com`.
+
+The value `*` is a special wildcard that matches all hosts.
+
+A port can optionally be specified. If omitted, it matches all ports.
+
+NOTE: Pkl follows the rules described in https://about.gitlab.com/blog/2021/01/27/we-need-to-talk-no-proxy/#standardizing-no_proxy[Standardizing `no_proxy`], except it does not look at environment variables.

+Allows to change default class and package names (derived from Pkl module names) in the generated code.
+
+When you need the generated class or package names to be different from the default names derived from the Pkl module names, you can define a rename mapping, where the key is the original Pkl module name prefix, and the value is its replacement.
+When you do, the generated code's `package` declarations, class names, as well as file locations, will be modified according to this mapping.
+
+The prefixes are replaced literally, which means that dots at the end are important.
+If you want to rename packages only, in most cases, you must ensure that you have an ending dot on both sides of a mapping (except for an empty mapping, if you use it), otherwise you may get unexpected results:
+
+----
+// Assuming the following mapping configuration:
+renames = [
+  "com.foo.": "x",  // Dot on the left only
+  "org.bar": "y.",  // Dot on the right only
+  "net.baz": "z"    // No dots
+]
+
+// The following renames will be made:
+"com.foo.bar" -> "xbar"       // Target prefix merged into the suffix
+"org.bar.baz" -> "y..baz"     // Double dot, invalid name
+"net.baz.qux" -> "z.qux"      // Looks okay, but...
+"net.bazqux"  -> "zqux"       // ...may cut the name in the middle.
+----
+
+When computing the appropriate target name, the longest matching prefix is used:
+
+----
+// Assuming the following mapping configuration:
+renames = [
+  "com.foo.Main": "w.Main",
+  "com.foo.": "x.",
+  "com.": "y.",
+  "": "z."

+com.baz.qux  -> y.baz.qux
+org.foo.bar  -> z.org.foo.bar
+----
+
+Keys in this mapping can be arbitrary strings, including an empty string.
+Values must be valid dot-separated fully qualifed class name prefixes, possibly terminated by a dot.

+
+[[windows-support]]
+=== Windows Support
+
+Pkl is now available on Windows! (https://github.com/apple/pkl/pull/492[#492])
+
+
+In addition to macOS and Linux, Pkl is now available for download on Windows operating systems.
+
+For installation instructions, consult xref:pkl-cli:index.adoc#windows-executable[Windows Executable] in the CLI reference.
+
+==== Writing cross-platform Pkl programs
+
+On Windows, the in-language filepath separator is still `/`.
+This means that most existing Pkl code should still continue working as-is.
+
+A small portion of programs will need to be updated to handle Windows support correctly.
+One example is the various conversion scripts that read input files as CLI flags.
+
+For example, here is a snippet from module https://github.com/apple/pkl-pantry/blob/d9571cdce407bb7f1687f81b945a4bfd24ce017d/packages/k8s.contrib/convert.pkl#L100C1-L103C74[k8s.contrib.convert]:
+
+.convert.pkl#L100-L103
+[source,pkl]
+----
+local inputUri =
+  if (input.startsWith(Regex(#"\w+:"#))) input      // absolute URI
+  else if (input.startsWith("/")) "file://\(input)" // absolute file path
+  else "file://\(read("env:PWD"))/\(input)"         // relative file path
+----
+
+On Windows, the env var `PWD` is a Windows-style path, like `C:\Foo\Bar\Baz`.
+With the above logic, `inputUri` can expand to a value like `"\file://C:\Foo\Bar\Baz/input.yaml"`.
+This would an invalid URI; the correct URI should be `"\file:///C:/Foo/Bar/Baz/input.yaml"`.
+
+Here is a possible fix for this code:
+
+[source,pkl]
+----
+import "pkl:platform"
+
+local inputUri =
+  if (input.startsWith(Regex(#"\w+:/"#))) input
+  else if (input.startsWith("/")) "file://\(input)"
+  else
+    let (pwd = read("env:PWD"))
+    let (
+      path =
+        if (platform.current.operatingSystem.name == "Windows")
+          "/\(pwd)/\(input)".replaceAll("\\", "/")
+        else "\(pwd)/\(input)"
+    )
+      "file://\(path)"
+----
+
+To learn more about this design, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0006-import-paths-on-windows.adoc[SPICE-0006].
+
+[[http-proxying]]
+=== HTTP proxying
+
+Pkl now supports proxying HTTP(S) requests (https://github.com/apple/pkl/pull/506[#506]).
+
+For users of the CLI, Pkl will by default look for proxy settings configured within the OS when on macOS, Windows, and GNOME environments.
+
+This can be changed by adding settings in the following locations:
+
+1. xref:pkl-cli:index.adoc#settings-file[Settings file]
+2. xref:language-reference:index.adoc#projects[PklProject file]
+3. `--http-proxy` and `--http-no-proxy` CLI flags
+
+As part of this, some changes have been made to the standard library. For details, see <<standard-library-changes,Standard Library changes>>.
+
+Users of the Java/Kotlin bindings can specify proxy settings when building an <<http-java-client,HTTP client>>.
+
+HTTP proxy settings are also added as new fields in the message-passing-api.
+Authors of external Pkl clients are encouraged to support these new fields to provide proxy support in their libraries.

+[[scheme-agnostic-project-dependencies]]
+=== Scheme-agnostic project dependencies
+
+Improvements have been made to project dependencies (https://github.com/apple/pkl/pull/486[#486]).
+
+A project dependency is a way to manage `package`-based modules.
+It provides two uses:
+
+1. A package can be imported through xref:language-reference:index.adoc#dependency-notation[dependency notation].
+2. Conflicting versions in the transitive dependency graph are resolved.
+
+Currently, dependencies can only be used with file-based modules.
+This can be limiting in some circumstances:
+
+1. JVM library users typically interact with Pkl by bundling Pkl files a classpath resources, and load them using `modulepath:` URIs.
+2. Go library users often embed Pkl code using the https://pkg.go.dev/embed#hdr-Directives[`go:embed` directive], and load them using https://pkg.go.dev/github.com/apple/pkl-go/pkl#WithFs[`WithFs`].
+
+This means that these users miss out on the benefits of project dependencies.
+
+Pkl 0.26 adds support for using dependencies in any hierarchical module scheme.
+This means that `modulepath:` users in Java can now declare projects and dependencies.
+This also means that other custom methods of embedding modules can also use dependency notation.
+
+[NOTE]
+====
+A _hierarchical_ URI is a URI whose path part starts with `/`, and in which `/` delimits path segments.
+
+The URI `myscheme:/foo.pkl` is hierarchical, whereas the URI `myscheme:foo.pkl` is not.

+
+[[typealias-scoping-fix-and-change]]
+=== Typealias scoping fix and change
+
+Improvements have been made to `typealias`es (https://github.com/apple/pkl/pull/144[#144], https://github.com/apple/pkl/pull/373[#373], https://github.com/apple/pkl/pull/516[#516]).
+
+Currently, a typealias that references a value on its enclosing module will break if used in another module.
+
+.myModule.pkl
+[source,pkl]
+----
+typealias StartsWithFoo = String(startsWith(foo))
+
+foo = "foo"
+----
+
+[source,pkl]
+----
+import "myModule.pkl"
+
+myStr: StartsWithFoo = "fooey"
+----
+
+This results in error:
+
+[source]
+----
+–– Pkl Error ––
+Cannot find property `foo`.
+
+1 | typealias StartsWithFoo = String(startsWith(foo))
+----
+
+This is a language bug that has been fixed.
+
+In the process of fixing this bug, we realized that the rules around variable resolution within typealiases were problematic.
+Typealiases are meant to be statically defined, and shouldn't be able to see properties that can be late-bound.
+Thus, a new rule is introduced: a typealias can only reference properties/methods that are `const`.
+
+This is a breaking change. To read more about this breakage and remediation steps, reference <<typealiases-are-treated-as-const>>.
+
+== Noteworthy [small]#🎶#
+
+Ready when you need them.
+
+[[pkldoc-improvements]]
+=== Pkldoc improvements
+
+The following improvements have been made to xref:pkl-doc:index.adoc[Pkldoc]:
+
+1. The documentation for the standard library no longer shows dependent packages, because every package implicitly depends on the standard library (https://github.com/apple/pkl/pull/503[#503]).
+2. If the standard library exists in the package list, it is shown first (https://github.com/apple/pkl/pull/165[#165]).
+3. Fewer characters are percent-encoded. For example, the `(` and `)` characters are no longer percent-encoded (https://github.com/apple/pkl/pull/489[#489]).
+
+[[standard-library-changes]]
+=== Standard library changes
+
+To support <<http-proxying,http proxying>>, several changes have been made to the standard library (https://github.com/apple/pkl/pull/506[#506]).
+
+* Module `pkl.settings` has new property `http`.
+* class `EvaluatorSettings` originally in `pkl.Project` has been moved to its own module.
+For backwards compatibility, `pkl.Project` now has a `typealias EvaluatorSettings` pointing to the new module, but it is marked `@Deprecated`.
+
+=== Java API Changes
+
+[[http-java-client]]
+==== HTTP Java Client
+
+A new Java API is introduced, named `org.pkl.core.http.HttpClient` (https://github.com/apple/pkl/pull/217[#217], https://github.com/apple/pkl/pull/295[#295], https://github.com/apple/pkl/pull/506[#506], https://github.com/apple/pkl/pull/518[#518]).
+This interface provides the ability to manage how Pkl makes HTTP(S) calls, including how it deals with CA certificates, as well as proxies.
+
+This client can be passed to Pkl's evaluator using `EvaluatorBuilder` for users of pkl-core, and `ConfigEvaluatorBuilder` for users of pkl-config-java or pkl-config-kotlin.
+
+[[http-module-key-factory]]
+==== New HTTP ModuleKeyFactory
+
+A new module key factory for HTTP(S) modules has been added (https://github.com/apple/pkl/pull/495[#495]), and can be built with `org.pkl.core.ModuleKeyFactories#http`.
+
+The preconfigured evaluator (`org.pkl.core.EvaluatorBuilder#preconfigured`) includes this module key.
+Users that build their own evaluator from scratch should add this module key factory if HTTP(S) modules are needed.
+
+Example:
+
+[source,diff]
+----
+ import org.pkl.core.EvaluatorBuilder;
+ import org.pkl.core.module.ModuleKeyFactories;
+
+ var evaluator = EvaluatorBuilder.unconfigured()
++  .addModuleKeyFactory(ModuleKeyFactories.http) // <1>
+   .build();
+----
+<1> Add `ModuleKeyFactories.http` to the set of module key factories used by this evaluator.
+
+If this module key factory is not added, Pkl may still make HTTP(S) requests if `ModuleKeyFactories.genericUrl` is included.
+However, this bypasses proxy and CA certificate settings.
+
+[[pkl-executor-changes]]
+==== `pkl-executor` changes
+
+A new set of parameters are now available to `org.pkl.executor.Executor` (https://github.com/apple/pkl/pull/217[#217], https://github.com/apple/pkl/pull/518[#518]).
+These new parameters are exposed by `org.pkl.executor.spi.v1.ExecutorSpiOptions2`.
+
+The new parameters are:
+
+* `certificateFiles`: A set of CA certificate files to trust when making HTTPS requests.
+* `certificateBytes`: A set of PEM-encoded CA certificate bytes to trust when making HTTPS requests.
+* `testPort`: An option that is used for internal testing only.
+
+These options are ignored when using a Pkl distribution whose version is lower than 0.26.0.
+
+[[message-passing-api-changes]]
+=== Message passing API changes
+
+A new property, `http`, is added to xref:bindings-specification:message-passing-api.adoc#create-evaluator-request[Create Evaluator Request] (https://github.com/apple/pkl/pull/506[#506], https://github.com/apple/pkl/pull/518[#518]).
+
+This allows for the configuration of Pkl's HTTP proxy, as well as CA certificates.
+
+[[rename-codegen-classes]]
+=== Ability to rename classes produced by Java/Kotlin code generators
+
+The Java and Kotlin code generators have a new option that allows users to change the name of Java/Kotlin classes that get produced during code generation (https://github.com/apple/pkl/pull/499[#499]).
+
+The CLIs have a new flag, `--rename`, and the Gradle plugin receives a similarly named property called `renames`.
+
+This option accepts a map from an old prefix to a new prefix, where longer prefixes have higher precedence than shorter prefixes.
+
+For example, when generating `module foo.Bar`, specifying `--rename foo.=com.foo.` will cause the Java/Kotlin code generators to emit package `com.foo`, and class `Bar`.
+
+== Breaking Changes [small]#💔#
+
+Things to watch out for when upgrading.
+
+[[typealiases-are-treated-as-const]]
+=== Typealiases are treated as `const`
+
+A breaking change has been made to typealiases (https://github.com/apple/pkl/pull/516[#516]).
+
+Typealiases are types that can stand in for another type declaration.
+
+The aliased type can have constraints, where these constraints can reference values defined on the enclosing module.
+
+.baseModule.pkl
+[source,pkl]
+----
+typealias MyValue = Any(isValid) // <1>
+
+isValid = true
+----
+<1> `isValid` is defined on the enclosing module.
+
+One problem with this is that typealiases are meant to be statically defined.
+Like classes, typealiases should not be changed by amending its enclosing module.
+
+[source,pkl]
+----
+amends "baseModule.pkl"
+
+isValid = false // <1>
+----
+<1> Despite this amended value, `typealias MyValue` should still stand for `Any(true)`.
+
+To have clearer semantics, a new rule is introduced: referenced members on the enclosing module must be `const`.
+Effectively, a typealias is treated as if it is also a `const` member.
+
+To fix the above typealias, the `const` modifier should be added to `isValid`.
+
+[source,diff]
+----
+ typealias MyValue = Any(isValid)
+ 
+-isValid = true
++const isValid = true
+----
+
+It might not always be valid to add the `const` modifier.
+For example, this property may be overwritten in a downstream module, so adding the `const` modifier this would break that module.
+In these cases, another fix is to self-import the enclosing module.
+This works because import declarations introduce values that are implicitly marked `const`.
+
+.baseModule.pkl
+[source,diff]
+----
++import "baseModule.pkl" // <1>
++
+-typealias MyValue = Any(isValid)
++typealias MyValue = Any(baseModule.isValid)
+ 
+ isValid = true
+----
+<1> Self import
+
+This change aligns with the behavior of class and annotation bodies.
+
+To read more about the rationale behind this change, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0007-const-checks-in-typealiases.adoc[SPICE-0007].
+
+[[expanded-dependency-notation-uris]]
+=== Expanded dependency notation URIs
+
+The parsing of relative path imports has changed (https://github.com/apple/pkl/pull/486[#486]).
+
+Currently, the declaration `import "@foo/bar.pkl"` is treated as the import of a dependency named `foo`, but _only_ when declared within file-based and package-based modules.
+In an HTTP-based module, for example, the above import is treated as "bar.pkl inside directory @foo".
+
+To <<scheme-agnostic-project-dependencies,improve project dependencies>>, such declarations are treated as dependency notation in all modules, and will fail with error "Cannot find dependency".
+
+Any import/reads that are intentionally relative-path imports will need to be updated to be prefixed with `./`.
+
+Example:
+
+[source,diff]
+----
+-import "@bar/foo.pkl"
++import "./@bar/foo.pkl"
+----
+
+[[minimum-java-version-bump]]
+=== Minimum Java version bumped to Java 17
+
+The minimum Java version for Pkl has been bumped to Java 17 (https://github.com/apple/pkl/pull/439[#439]).
+
+This means that when running the xref:pkl-cli:index.adoc#java-executable[jpkl] CLI, the installed `java` is expected to be Java 17 or higher.
+This also means that users of the JVM libraries need to be on at least Java 17 or higher.
+
+[[minimum-gradle-version-bump]]
+=== Gradle plugin minimum version bump
+
+The minimum Gradle version for the xref:main:pkl-gradle:index.adoc[Gradle plugin] is now 8.1 (https://github.com/apple/pkl/pull/454[#454]).
+
+[[path-encoding-changes]]
+=== Path encoding changes
+
+In order to support Windows, the output of some Pkl tools have unsafe characters encoded in a special format (https://github.com/apple/pkl/pull/489[#489]).
+
+On Windows, the characters `<`, `>`, `:`, `"`, `\`, `|`, `?`, and `*` are reserved and cannot exist in a filename.
+Additionally, the ASCII control character code points `0x0` through `0x1f` are also illegal.
+
+These characters are encoded by wrapping their hexadecimal code point value in parentheses.
+For example, the character `:` is encoded as `(3a)`.
+
+In some scenarios, files that get written to disk will be encoded.
+These are:
+
+* Files generated by Pkldoc.
+* `*.kt` files produced by the Kotlin code generator.
+* Packages written to the cache directory.
+
+To learn more about this design, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0003-windows-safe-paths.adoc[SPICE-0003].
+
+==== Pkldoc links changes
+
+The links generated by Pkldoc have changed.
+
+For example, a module called `module `foo<bar`` creates file `foo(3c)bar.html`, instead of `foo<bar.html`.
+
+As part of this change, some Pkldoc links have also changed.
+
+==== Cache directory prefix changes
+
+The cache directory has been changed from `<moduleCacheDir>/package-1` to `<moduleCacheDir>/package-2`.
+
+If Pkl's dependencies are vendored within a repository, these dependencies will need to be re-vendored.
+
+=== Java API Breaking Changes
+
+The following Java APIs have breaking changes:
+
+|===
+|Class/method | Breaking change
+
+|`org.pkl.cli.commands.CliDownloadPackageCommand`
+|Renamed to `org.pkl.cli.commands.CliPackageDownloader`
+
+|`org.pkl.cli.commands.CliAbstractProjectCommand`
+|Renamed to `org.pkl.cli.commands.CliProjectCommand`
+
+|`org.pkl.config.java.InvalidMappingException`
+|Fields `pklName` and `javaName` are now `private`.
+
+|`org.pkl.core.packages.PackageResolver#getInstance`
+|New parameter `httpClient` added
+
+|`org.pkl.core.repl.ReplServer.ReplServer`
+|New parameter `httpClient` added
+
+|`org.pkl.commons.cli.CliBaseOptions`
+|New parameters `testPort`, `httpProxy`, `httpNoProxy` added
+|===
+
+[[standard-library-breaking-changes]]
+=== Standard library breaking changes
+
+Class `pkl.Project.EvaluatorSettings` has been removed.
+A new (deprecated) typealias is added that points to new module `pkl.EvaluatorSettings`.
+For both of these, see https://github.com/apple/pkl/pull/506[#506].
+
+[[type-checked-settings-file]]
+=== Type-checked settings file
+
+The loading of the xref:pkl-cli:index.adoc#settings-file[settings file] has changed (https://github.com/apple/pkl/pull/477[#477]).
+
+The settings file is a way to control the behavior of the Pkl CLI.
+This module is expected to `amends "pkl:settings"`, but this behavior was not checked.
+
+In 0.26, it is an error if the settings module neither amends `"pkl:settings"`, nor set its `output.value` to an instance of the settings module.
+
+[[empty-directories-excluded-from-packaging]]
+=== Empty directories excluded from packaging
+
+Currently, the `pkl project package` command will bundle empty directories into the resulting ZIP file.
+
+In version 0.26, this has been changed to exclude these directories (https://github.com/apple/pkl/pull/330[#330]).
+This means that the packages can produce a _different_ checksum if there are any empty directories.
+
+This does not break the usage of existing packages, and does not affect compatibility of new packages used with older Pkl 0.25.
+
+However, this can break certain workflows.
+The `pkl project package` command runs a publish check, to determine if a package has already been published but with a different checksum.
+When upgrading, users might encounter an error message like the following:
+
+[source]
+----
+-- Pkl Error --
+Package `package://example.com/foo@1.0.0` was already published with different contents.
+----
+
+To mitigate, the package's version needs to be bumped, even if package contents have not changed.
+
+== Miscellaneous [small]#🐸#
+
+The following changes have been made that are neither new features nor breaking changes.
+
+* Pkl's user-agent header for HTTP requests has been tweaked to add a semicolon (https://github.com/apple/pkl/pull/221[#221]). Here is an example difference:
++
+Before: `Pkl/0.26 (macOS native)` + 
+After: `Pkl/0.26 (macOS; native)`
+* Documentation improvements (https://github.com/apple/pkl/pull/120[#120], https://github.com/apple/pkl/pull/121[#121], https://github.com/apple/pkl/pull/142[#142], https://github.com/apple/pkl/pull/121[#121], https://github.com/apple/pkl/pull/337[#337], https://github.com/apple/pkl/pull/341[#341], https://github.com/apple/pkl/pull/372[#372], https://github.com/apple/pkl/pull/386[#386], https://github.com/apple/pkl/pull/391[#391], https://github.com/apple/pkl/pull/397[#397], https://github.com/apple/pkl/pull/422[#422], https://github.com/apple/pkl/pull/436[#436], https://github.com/apple/pkl/pull/469[#469], https://github.com/apple/pkl/pull/484[#484], https://github.com/apple/pkl/pull/485[#485], https://github.com/apple/pkl/pull/[#491]).
+* Optimization: `const` access is checked when variables are resolved, instead of every time the variable is accessed (https://github.com/apple/pkl/pull/438[#438]).
+* Optimization: use logical AND instead of bitwise AND when comparing numbers (https://github.com/apple/pkl/pull/102[#102]).
+* Mark Java classes `final` (https://github.com/apple/pkl/pull/458[#458]).
+* Migrate code to newer JDK17 features, and clean up existing Java code (https://github.com/apple/pkl/pull/451[#451], https://github.com/apple/pkl/pull/458[#458], https://github.com/apple/pkl/pull/512[#512]).
+* Improve rendering of string values within generated `<file>.pkl-expected.pcf` files when running `pkl test` (https://github.com/apple/pkl/pull/416[#416]).
+* Improve performance of loading Pkl's built-in CA certificates (https://github.com/apple/pkl/pull/518[#518]).
+
+== Bug Fixes [small]#🐜#
+
+The following bugs have been fixed.
+
+* `Collection#sortWith` produces un-sorted output (https://github.com/apple/pkl/pull/394[#394]).
+* Property `typedType` in module `pkl.reflect` reflects upon `Type`, instead of `Typed` (https://github.com/apple/pkl/pull/426[#426]).
+* `const` members can be assigned to when via an object spread  (https://github.com/apple/pkl/pull/428[#428]).
+* Relative globbed reads resolve to the same value in different modules (https://github.com/apple/pkl/pull/449[#449]).
+* Performance bug: globbed imports and globbed reads expand to an unbounded number of root nodes (https://github.com/apple/pkl/pull/449[#449]).
+* Relative globbed imports within a package match no modules (https://github.com/apple/pkl/pull/496[#496]).
+* Constraints within typealiases resolve to the wrong values (https://github.com/apple/pkl/pull/144[#144]).
+* Members of `pkl.reflect` cannot be rendered (https://github.com/apple/pkl/pull/170[#170], https://github.com/apple/pkl/pull/470[#470]).
+* Throws `NullPointerException` if "List Resources Response" or "List Modules Response" messages contain both null `pathElements` and `error` (https://github.com/apple/pkl/pull/480[#480]).
+* Classes of `com.oracle.truffle` are not shaded in pkl-config-java-all and pkl-tools (https://github.com/apple/pkl/pull/238[#238]).
+* Throws `PklBugException` when running publish check on an invalid URL (https://github.com/apple/pkl/pull/441[#441]).

+
+[#typecheck-improvements]
+=== Improved typechecking of `Listing` and `Mapping` types
+
+Typechecking of `Listing` and `Mapping` types has been improved (https://github.com/apple/pkl/pull/628[#628], https://github.com/apple/pkl/pull/725[#725], https://github.com/apple/pkl/pull/740[#740], https://github.com/apple/pkl/pull/752[#752], https://github.com/apple/pkl/pull/778[#778], https://github.com/apple/pkl/pull/781[#781]).
+
+Today, the typecheck `listing: Listing<E>` immediately evaluates all listing elements to check that they have type `E`.
+Likewise, the typecheck `mapping: Mapping<K, V>` immediately evaluates all mapping values to check that they have type `V`.
+
+For example, the typecheck `listing: Listing<Bird>` proceeds as follows:
+
+1. Check that `listing` has type `Listing`
+2. Evaluate each listing element and check that it has type `Bird`
+
+This behavior is different from how the rest of Pkl works.
+Generally, Pkl only evaluates code that affects program output.
+
+For example, consider the following program:
+
+[source,pkl]
+----
+class Bird {
+  name: String
+  canFly: Boolean
+}
+
+local bird: Bird = new {
+  name = "Pidgy"
+  canFly = throw("uh oh")
+}
+
+birdName = bird.name
+----
+
+Even though `bird.canFly` throws an error, the above program succeeds because `bird.canFly` is not part of the program's output and hence is never accessed (Note that `bird` is a _local_ property).
+
+Typechecks of `Mapping` and `Listing` types have been changed to match this behavior.
+Mapping and listing values are now only typechecked if and when they are accessed.
+
+NOTE: Mapping _keys_ are still eagerly checked.
+
+This change causes some previously failing programs to evaluate successfully:
+
+[source,pkl]
+----
+local myNumbers: Listing<Int> = new { 1; 2; "uh oh" } 
+result = myNumbers[0]
+----
+In Pkl 0.26 and below, the above program fails with a type mismatch error because element `"uh oh"` is typechecked when `myNumbers` is accessed.
+In Pkl 0.27, the same program succeeds, because only element `myNumbers[0]` is part of the program's output and its typecheck succeeds.
+
+As another consequence of this change, some Pkl programs now complete more quickly:
+
+[source,pkl]
+----
+local allBirds: Mapping<String, Bird> = import*("**/bird.pkl")
+
+environment: "prod"|"qa"
+
+cluster: String
+
+myBird = allBirds["\(environment)/\(cluster)/bird.pkl"] // <1>
+----
+In Pkl 0.26 and below, all modules matching `**/bird.pkl` are imported when `allBirds` is accessed and typechecked.
+This can take a long time.
+In Pkl 0.27, only module `"\(environment)/\(cluster)/bird.pkl"` is imported because only this module is part of the program's output.
+
+To learn more about this change, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0010-overhauled-mapping-listing-typechecks.adoc[SPICE-0010].
+
+=== External readers
+
+A new feature has been added to allow Pkl to spawn external processes to read resources and modules (https://github.com/apple/pkl/pull/660[#660], https://github.com/apple/pkl/pull/762[#762], https://github.com/apple/pkl/pull/766[#766], https://github.com/apple/pkl/pull/770[#770]).
+
+Today, users who use Pkl as a library can define custom module and resource readers.
+This allows authors to extend how Pkl performs I/O.
+
+For example, users can implement a reader that reads the `secret:` scheme, where they define exactly how the bytes are fetched in the host runtime.
+
+[source,pkl]
+----
+result = read("secret:mypassword") // <1>
+----
+<1> `secret:` is a custom scheme defined by the host runtime.
+
+However, CLI users have been left out.
+
+In Pkl 0.27, a new extension point is added to allow users to implement module and resource readers as external processes.
+When run, Pkl will spawn the external process, and talk to the process via xref:bindings-specification:message-passing-api.adoc[message passing].
+
+To learn more about this feature, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0009-external-readers.adoc[SPICE-0009].

+
+[[import-analysis]]
+=== Import analysis API
+
+A new API has been added to analyze the import graph of Pkl modules (https://github.com/apple/pkl/pull/695[#695]).
+
+This API comes in four forms:
+
+1. A standard library module: `pkl:analyze`
+2. A CLI command: `pkl analyze imports`
+3. A Java API: `org.pkl.core.Analyzer`
+4. A Gradle API: `org.pkl.gradle.task.AnalyzeImportsTask`
+
+Some use-cases for this API are:
+
+* For build tools to perform out-of-date checks. Build tools can invalidate a cached result if any of the transitive modules have changed.
+* Static code analysis, to determine how Pkl modules depend on each other.
+
+With this API, xref:pkl-gradle:index.adoc[] now by default <<transitive-modules-computed-by-default,computes the transitive modules>> for many of its tasks.
+
+Here is an example of the CLI in use:
+
+[source,shell]
+----
+pkl analyze imports -f json myModule.pkl # <1>
+----
+<1> `-f` means: produce output in JSON.
+
+Produces:
+
+[source,json]
+----
+{
+  "imports": {
+    "file:///my/proj/myModule.pkl": [
+      {
+        "uri": "projectpackage://example.com/birds@1.0.0#/Bird.pkl"
+      }
+    ],
+    "projectpackage://example.com/birds@1.0.0#/Bird.pkl": []
+  },
+  "resolvedImports": {
+    "file:///my/proj/myModule.pkl": "file:///my/proj/myModule.pkl",
+    "projectpackage://example.com/birds@1.0.0#/Bird.pkl": "file:///my/birds/Bird.pkl"
+  }
+}
+----
+
+From this output, we can see that `myModule.pkl` imports `Bird.pkl` from the `birds` package.
+We can also see that the module `projectpackage://example.com/birds@1.0.0#/Bird.pkl` resolves to disk location `\file:///my/birds/Bird.pkl` (we can deduce that `birds` is a xref:language-reference:index.adoc#local-dependencies[local dependency]).

+
+== Noteworthy [small]#🎶#
+
+Ready when you need them.
+
+=== Colored output
+
+The Pkl CLI will now emit some messages in color (https://github.com/apple/pkl/pull/552[#552], https://github.com/apple/pkl/pull/746[#746], https://github.com/apple/pkl/pull/771[#771], https://github.com/apple/pkl/pull/779[#779]).
+
+Here is a sneak peek of colored error messages in action.
+
+image::error_sample.png[syntax highlighted output]
+
+Thanks to https://github.com/thomaspurchas[@thomaspurchas] for contributing to this feature!
+
+=== `const local` object members
+
+The `const` modifier can be applied to object members, provided that they are also `local` (https://github.com/apple/pkl/pull/678[#678]).
+
+Currently, regular object members are not allowed to have the `const` modifier.
+This introduces an artificial pain point.
+
+For example, given the following module:
+
+[source,pkl]
+----
+amends "Bird.pkl"
+
+import "Bird.pkl"
+
+local northAmerica = "North America"
+
+local typealias NorthAmericanBird = Bird(this.origin == northAmerica) // <1>
+----
+<1> Error: cannot reference `northAmerica` from here because it is not `const`.
+
+This is invalid code, because this typealias is referencing a non-const value on the enclosing module.
+However, is not possible fix this by adding the `const` modifier to `northAmerica`.
+This is because this module `amends "Bird.pkl"`, which means that this module is considered a regular object and not a class.
+This means that any members declared here are _object members_, and not _class members_.
+
+In Pkl 0.27, a new rule is introduced to allow the `const` modifier to be applied to object members, provided that they are also `local`.
+
+This change affects object properties, as well as object methods.
+
+To read more about this design, consult https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0011-const-object-members.adoc[SPICE-0011].
+
+=== Pkl CLI changes
+
+==== New CLI Flags
+
+Some new common flags have been added to the CLI (https://github.com/apple/pkl/pull/660[#660], https://github.com/apple/pkl/pull/746[#746]).
+
+|===
+|Flag |Description
+
+|`--color`
+|Format messages with ANSI color codes
+
+|`--external-module-reader`
+|Shell out to a process to read certain modules.
+
+|`--external-resource-reader`
+|Shell out to a process to read certain resources.
+|===
+
+==== New command: `pkl analyze imports`
+
+As part of the set of APIs added for <<import-analysis,import analysis>>, a new subcommand has been added called `analyze imports` (https://github.com/apple/pkl/pull/695[#695]).
+
+For details, consult the xref:pkl-cli:index.adoc#command-analyze-imports[CLI documentation].
+
+=== Kotlin/Java code generator improvements
+
+Various improvements have been made to the Kotlin and Java code generators (https://github.com/apple/pkl/pull/705[#705], https://github.com/apple/pkl/pull/710[#710], https://github.com/apple/pkl/pull/714[#714], https://github.com/apple/pkl/pull/721[#721], https://github.com/apple/pkl/pull/729[#729]).
+
+==== Java codegen improvements
+
+* Only generate `hashCode()`, `equals()`, and `toString()` methods for Java classes that are instantiable.
+* Add support for Spring Boot 3.
+* Make module classes also implement serializable.
+* Make empty Java classes instantiable.
+
+==== Kotlin codegen improvements
+
+* Skip generation of `copy()`, `equals()`, `hashCode()`, `toString()` methods for abstract Kotlin classes.
+* Don't implement `Serializable` for abstract classes
+* Add support for Spring Boot 3.
+
+Thanks to https://github.com/translatenix[@translatenix] for contributing these improvements!
+
+=== Gradle Plugin changes
+
+==== New `AnalyzeImportsTask`
+
+A new task called `org.pkl.gradle.task.AnalyzeImportsTask` is introduced (https://github.com/apple/pkl/pull/695[#695]).
+
+This task is the Gradle analogy to `pkl analyze imports`.
+
+Example:
+
+[tabs]
+====
+build.gradle::
++
+[source,groovy]
+----
+pkl {
+  analyzers {
+    imports {
+      appConfig {
+        sourceModules.add(file("src/main/resources/appConfig.pkl"))
+      }
+    }
+  }
+}
+----
+
+build.gradle.kts::
++
+[source,kotlin]
+----
+pkl {
+  analyzers {
+    imports {
+      register("appConfig") {
+        sourceModules.add(file("src/main/resources/appConfig.pkl"))
+      }
+    }
+  }
+}
+----
+====
+
+For more details, consult the xref:pkl-gradle:index.adoc#analyze-imports[documentation].
+
+==== Tracked file outputs
+
+Tasks created by the Pkl plugin now declare tracked output files (https://github.com/apple/pkl/pull/403[#403]).
+
+This means that downstream tasks do not need to declare an explicit dependency on the Pkl task.
+
+For example, assuming that `evalPkl` is an `EvalTask`:
+
+.build.gradle.kts
+[source,diff]
+----
+ val myGradleTask by tasks.registering {
+   inputs.files(evalPkl)
+-  dependsOn(evalPkl) // <1>
+ }
+----
+<1> No longer necessary to declare this dependency.
+
+[[transitive-modules-computed-by-default]]
+==== `transitiveModules` computed by default 
+
+The `transitiveModules` property of a task is now computed by building the import graph of the source modules (https://github.com/apple/pkl/pull/695[#695]).
+
+This means that Pkl-related tasks no longer need to declare their set of transitive modules, because the pkl-gradle plugin will compute this automatically.
+
+NOTE: This adds latency to each task. To opt out of this behavior, set `transitiveModules` explicitly.
+
+=== Standard library changes
+
+==== Additions to `pkl:base`
+
+New properties and methods have been added to the classes of `pkl:base` (https://github.com/apple/pkl/pull/666[#666], https://github.com/apple/pkl/pull/683[#683]).
+
+New properties and methods have been added to {uri-stdlib-Listing}[`Listing`] and {uri-stdlib-Mapping}[`Mapping`].
+
+One of the goals of this change is to improve the experience of authoring constraints.
+This eliminates the need to convert to collection types as often.
+
+The added properties and methods are:
+
+* {uri-stdlib-Listing}#first[`Listing.first`]
+* {uri-stdlib-Listing}#firstOrNull[`Listing.firstOrNull`]
+* {uri-stdlib-Listing}#last[`Listing.last`]
+* {uri-stdlib-Listing}#lastOrNull[`Listing.lastOrNull`]
+* {uri-stdlib-Listing}#single[`Listing.single`]
+* {uri-stdlib-Listing}#singleOrNull[`Listing.singleOrNull`]
+* {uri-stdlib-Listing}#every()[`Listing.every()`]
+* {uri-stdlib-Listing}#any()[`Listing.any()`]
+* {uri-stdlib-Listing}#contains()[`Listing.contains()`]
+* {uri-stdlib-Mapping}#containsValue()[`Mapping.containsValue()`]
+* {uri-stdlib-Mapping}#every()[`Mapping.every()`]
+* {uri-stdlib-Mapping}#any()[`Mapping.any()`]
+
+With this, the following change can be made to existing constraints:
+
+[source,diff]
+----
+-ipAddresses: Listing<String>(toList().contains("127.0.0.1"))
++ipAddresses: Listing<String>(contains("127.0.0.1"))
+----
+
+Additionally, a new method is added to `String`, called {uri-stdlib-String}#splitLimit()[`String.splitLimit()`].
+
+==== Additions to `pkl:EvaluatorSettings`
+
+New properties have been added to `pkl:EvaluatorSettings` (https://github.com/apple/pkl/pull/660[#660], https://github.com/apple/pkl/pull/746[#746]).
+
+These are:
+
+* {uri-stdlib-evaluatorSettingsModule}/#color[`color`]
+* {uri-stdlib-evaluatorSettingsModule}/#externalModuleReaders[`externalModuleReaders`]
+* {uri-stdlib-evaluatorSettingsModule}/#externalResourceReaders[`externalResourceReaders`]
+
+==== `String` to `Number` conversion improvements.
+
+The `String` to `Number` converter methods, for example,  {uri-stdlib-StringToInt}[`String.toInt()`], can now handle underscore separators (https://github.com/apple/pkl/pull/578[#578], https://github.com/apple/pkl/pull/580[#580]).
+
+This better aligns with the source code representation of xref:language-reference:index.adoc#integers[number literals].
+
+[source,pkl]
+----
+myNum = "1_000".toInt() // <1>
+----
+<1> Result: `1000`
+
+==== New module: `pkl:analyze`
+
+As part of <<import-analysis>>, a new standard library module is added called `pkl:analyze` (https://github.com/apple/pkl/pull/695[#695]).
+
+This module provides an API for computing the total import graph given a set of input modules.
+This API treats the inputs as entrypoints, and produces a graph representing the entire dependency tree, including transitive imports.
+
+Example:
+[source,pkl]
+----
+import "pkl:analyze"
+
+importGraph: analyze.ImportGraph = analyze.importGraph(Set("file:///path/to/my/module.pkl"))
+----
+
+For details, see the {uri-stdlib-analyzeModule}[documentation].
+
+=== Annotations on `PklProject` added to packages
+
+When creating packages, some annotations on a `PklProject` will affect how pkldoc generates documentation.
+
+* `@Unlisted`: Omit the package from publishing documentation.
+* `@Deprecated`: Add information on the package to show that it is deprecated. 
+
+Example:
+
+.PklProject
+[source,pkl]
+----
+@Deprecated
+amends "pkl:Project"
+----
+
+=== Test report improvements
+
+The report generated from `pkl test` has been overhauled and improved (https://github.com/apple/pkl/pull/498[#498], https://github.com/apple/pkl/pull/628[#682], https://github.com/apple/pkl/pull/738[#738], https://github.com/apple/pkl/pull/771[#771]).
+
+* Tests are grouped into either the `facts` or `examples` section.
+* A summary line is added, describing how many tests have passed and failed, and how many assertions have passed and failed.
+* Test results are colored.
+* The ✅ and ❌ emojis are replaced with ✔ and ✘.
+* Thrown errors are reported within the test.
+
+Here is a sneak peek of the new test result output.
+
+image::test_sample.png[]
+
+Thanks to https://github.com/jjmaestro[@jjmaestro] for contributing to this improvement!
+
+=== Java API additions
+
+==== New API: `org.pkl.core.Analyzer`
+
+As part of <<import-analysis>>, a new Java API called `org.pkl.core.Analyzer` is introduced (https://github.com/apple/pkl/pull/695[#695]).
+
+==== New methods
+
+The following methods are added:
+
+**pkl-executor**
+
+* `org.pkl.executor.ExecutorException.getPklVersion`
+* `org.pkl.executor.ExecutorException.ExecutorException(java.lang.String, java.lang.Throwable, java.lang.String)`
+
+**pkl-core**
+
+* `org.pkl.core.module.ModuleKeyFactories.externalProcess(java.lang.String, org.pkl.core.externalreader.ExternalReaderProcess)`
+* `org.pkl.core.module.ModuleKeyFactories.externalProcess(java.lang.String, org.pkl.core.externalreader.ExternalReaderProcess, long)`
+
+== Breaking Changes [small]#💔#
+
+Things to watch out for when upgrading.
+
+=== Java API breaking changes
+
+The following Java APIs have breaking changes:
+
+|===
+|Class/method | Breaking change
+
+|`org.pkl.core.runtime.TestResults`
+|Moved to `org.pkl.core.TestResults`, turned into a record, and largely restructured.
+
+|`org.pkl.core.module.ModuleKeyFactories.closeQuietly`
+|Deprecated for removal in favor of `org.pkl.core.Closeables.closeQuietly`.
+|===
+
+=== Spring Boot 2 support dropped
+
+The Java code generator no longer supports Spring Boot 2.x (https://github.com/apple/pkl/pull/729[#729]).
+
+Spring Boot 2 users can continue to use the Pkl 0.26 code generator.
+
+=== `pkl test` considered failing when writing examples
+
+If running `pkl test` results in `pkl-expected.pcf` files being written, the test now exits with exit code `10` (https://github.com/apple/pkl/pull/738[#738]).
+
+Additionally, the junit reports will consider the test as failing.
+
+=== `Listing` and `Mapping` typecheck changes
+
+Due to changes to <<typecheck-improvements,Listing and Mapping typechecking>>, some previously failing programs now succeed.
+This can happen when erroneous code is never evaluated because it does not affect program output:
+
+[source,pkl]
+----
+local myNumbers: Listing<Int> = new { 1; 2; "uh oh" } 
+result = myNumbers[0] // <1>
+----
+<1> In Pkl 0.26 and below, throws a type mismatch error.
++
+In Pkl 0.27, yields `1`.
+
+== Miscellaneous [small]#🐸#
+
+* Make pkl-doc top box include a preview of the rest of module-level documentation (https://github.com/apple/pkl/pull/570[#570]).
+* Module `pkl-core` now has a dependency on `org.msgpack:msgpack-core` (https://github.com/apple/pkl/pull/660[#660]). Users concerned about potential version conflicts can use one of Pkl's shaded fat JARs (`pkl-config-java-all`, `pkl-tools`).
+* Make PklProject.deps.json files end in a newline (https://github.com/apple/pkl/pull/664[#644]).
+* Fix invalid syntax of code examples in stdlib doc comments (https://github.com/apple/pkl/pull/703[#703]).
+* Update Java dependencies (https://github.com/apple/pkl/pull/689[#689], https://github.com/apple/pkl/pull/767[#767]).
+* Add jbang catalog support (https://github.com/apple/pkl/pull/655[#655]).
+* Documentation improvements (https://github.com/apple/pkl/pull/623[#623], https://github.com/apple/pkl/pull/680[#680], https://github.com/apple/pkl/pull/682[#682], https://github.com/apple/pkl/pull/685[#685], https://github.com/apple/pkl/pull/687[#687], https://github.com/apple/pkl/pull/703[#703], https://github.com/apple/pkl/pull/704[#704], https://github.com/apple/pkl/pull/715[#715], https://github.com/apple/pkl/pull/730[#730], https://github.com/apple/pkl/pull/753[#753]).
+
+== Bug Fixes [small]#🐜#
+
+The following bugs have been fixed.
+
+* CLI `--property` flags containing `=` in property values are not parsed correctly (https://github.com/apple/pkl/issues/630[#630]).
+* Thrown `PklBugException` when reading assets from a local project dependency (https://github.com/apple/pkl/issues/641[#641]).
+* Thrown `PklBugException` when PklProjects have a cyclical local dependency (https://github.com/apple/pkl/pull/731[#731]).
+* Thrown exception when sending `ReadResourceResponse` or `ReadModuleResponse` where both `contents` and `error` are `null` (https://github.com/apple/pkl/pull/657[#657]).
+* Double unary minus is evaluated as single unary minus (https://github.com/apple/pkl/pull/697[#697]).
+* Kotlin compiler fails to compiler generated classes with "copy overrides nothing" for subclasses of abstract classes (https://github.com/apple/pkl/issues/569[#569]).
+* "Unexpected error" thrown when `Module.output` has its type overridden (https://github.com/apple/pkl/issues/709[#709]).
+* "Unexpected error" thrown when loading files with non-ASCII characters (https://github.com/apple/pkl/issues/653[#653]).
+* Type parameters in `new Mapping<TypeA, TypeB>`/`new Listing <Type>` are not checked (https://github.com/apple/pkl/issues/405[#405]).
+* Comparison methods of `pkl:semver` are incorrect (https://github.com/apple/pkl/issues/772[#772]).

+== Highlights [small]#💖#
+
+News you don't want to miss.
+
+=== New parser
+
+Pkl has new parser (https://github.com/apple/pkl/pull/917[#917], https://github.com/apple/pkl/pull/957[#957], https://github.com/apple/pkl/pull/962[#962])!
+
+The first step to evaluating a program is to parse its source code into a parse tree.
+Currently, Pkl uses link:{uri-antlr}[ANTLR] to generate parser code from grammar files.
+
+Using this approach has allowed for rapidly iterating and changing the language's grammar.
+However, Pkl's grammar has matured; it's not as likely that the grammar will change from one version to the next.
+Additionally, the current parser's performance has become more painful as projects written in Pkl grow in size.
+In many cases, parsing can take up most of the time spent during evaluation.
+
+In 0.28, the ANTLR-generated parser is being replaced by a handwritten parser.
+In benchmarking tests, this has shown to improve parsing speed by around two orders of magnitude.
+Here are some quick comparisons between the two parsers, run on a MacBook Pro M4 Max machine, with 5 warmup iterations, and run for 10 iterations:
+
+|===

+|5.9ms

+Ready when you need them.
+
+=== CLI improvements
+
+==== Colored help messages
+
+The `pkl`, `pkldoc`, `pkl-codegen-java`, and `pkl-codegen-kotlin` CLIs now emits help text with colors (https://github.com/apple/pkl/pull/947[#947]).
+
+Here is a sneak peek:
+
+image::pkl-cli-help-new.png[new pkl cli help output]
+
+Thanks to https://github.com/gordonbondon[@gordonbondon] for their contribution!
+
+==== `jpkl` support on Windows
+
+The `jpkl` executable is now supported on Windows (https://github.com/apple/pkl/pull/872[#872]).
+
+`jpkl` is a fat jar that can be executed directly when on macOS and Linux, but current users of Windows are required to execute it with `java -jar <path/to/jpkl>`.
+
+In 0.28, Windows users can also call execute this command directly.
+To do so, the filename should be called `jpkl.bat`, and placed in `PATH`.
+
+=== Type constraint changes
+
+Type annotations that are executed as a result of calling a constraint expressions now perform an eager typecheck (https://github.com/apple/pkl/pull/964[#964]).
+
+In Pkl 0.27, we changed how xref:0.27.adoc#typecheck-improvements[typechecks are executed for `Listing` and `Mapping`] types.
+
+However, this had two unintended side effects:
+
+For one, error messages from certain failing constraints show `?` in place of values that are failing.
+
+The following snippet:
+
+[source%parsed,pkl]
+----
+class Bird { name: String }
+
+bird: Listing<Bird>(firstOneIsQuail) = new {
+  new { name = "Pigeon" }
+  new { name = "Quail" }
+}
+
+local firstOneIsQuail = (it: Listing<Bird>) -> it[0].name == "Quail"
+----
+
+Produces the following error message:
+
+[source]
+----
+–– Pkl Error ––
+Type constraint `firstOneIsQuail` violated.
+Value: new Listing { ?; ? }
+
+3 | bird: Listing<Bird>(firstOneIsQuail) = new {
+                        ^^^^^^^^^^^^^^^
+----
+
+:fn-typecheck-details: footnote:[See https://github.com/apple/pkl-evolution/blob/main/spices/SPICE-0010-overhauled-mapping-listing-typechecks.adoc#delegating-objects[delegating objects] in SPICE-0010 for more details on this behavior.]
+
+This is happening because lazy typechecks of mappings and listings will return a _new_ listing. Because the lambda's argument is defined as ``it: Listing<Bird>``, the value being passed into the function body is this new listing{fn-typecheck-details}.
+
+Secondly, some constraints became less strict, allowing more values to pass.
+
+The following snippet fails in Pkl 0.26, but passes in Pkl 0.27:
+

+class Bird { name: String }
+
+local nonEmpty = (it: Listing<Bird>) -> !it.isEmpty
+
+birds: Listing(nonEmpty) = new { 1; 2; 3 }
+----
+
+This is because the function parameter `it: Listing<Bird>` does not actually check members of the argument until they are accessed, and the function body `!it.isEmpty` does not access any members.
+
+To address both of these issues, the rule for executing type constraints has changed.
+When executing a type annotation, mapping and listing typechecks are always _eager_.
+This means that Pkl will check that each member of the mapping/listing conforms to the type parameter.
+
+=== Java 22+ support
+
+Pkl's Java libraries now support Java 22 and higher (https://github.com/apple/pkl/pull/876[#876]).
+
+Thanks to https://github.com/sgammon[@sgammon] for their contribution!
+
+=== New standard library method
+
+The `pkl:math` standard library module has a new method, called {uri-stdlib-mathModule}/index.html#atan2()[atan2] (https://github.com/apple/pkl/pull/819[#819]).
+It computes the https://en.wikipedia.org/wiki/Atan2[2-argument arctangent].
+
+Thanks to https://github.com/gordonbondon[@gordonbondon] for their contribution!
+
+=== Overhauled for-generator implementation
+
+The implementation of xref:language-reference:index.adoc#for-generators[for-generators] has been overhauled (https://github.com/apple/pkl/pull/844[#844]).
+
+This fixes some known bugs with the current for-generator implementation, and also improves code health by reducing complexity and removing workarounds and band-aids.
+
+Thanks to https://github.com/odenix[@odenix] for their contribution!
+
+=== Java code generator improvements
+
+Improvements have been made to the Java code generator (https://github.com/apple/pkl/pull/792[#792]).
+
+In pkl-codegen-java, the `--params-annotation` flag now accepts `none` as a value, which causes the code generator to skip adding annotations to a constructor's parameters.
+Additionally, the Kotlin API `org.pkl.codegen.java.JavaCodeGeneratorOptions.paramsAnnotation` is now nullable.
+If null, this also skips adding annotations.
+
+By default, this annotation is set to `org.pkl.config.java.mapper.Named`, or none if the `--generate-spring-boot-config` flag is set.
+
+This is useful for those compiling Java code with the `-parameters` flag set, because the pkl-config-java library is able to map into these classes without any extra annotations.
+
+Thanks to https://github.com/odenix[@odenix] for their contribution!
+
+=== Kotlin code generator improvements
+
+Improvements have been made to the Kotlin code generator (https://github.com/apple/pkl/pull/793[#793]).
+
+Currently, the output of `toString()` on a generated Kotlin class differs depending on if it was generated as a data class or as a regular class.
+
+In Pkl 0.28, this method produces the same format, and matches the format used by data classes.
+
+Thanks to https://github.com/odenix[@odenix] for their contribution!
+
+=== pkldoc improvements
+
+pkldoc has a new flag to write real files instead of symlinks (https://github.com/apple/pkl/pull/824[#824]).
+
+Currently, pkldoc creates a symlink called "current", which points to the latest non-prerelease version of a package.
+However, these symlinks can be problematic for some systems.
+
+A new flag, `--no-symlinks`, and a similarly named Gradle property, `noSymlinks`, instructs pkldoc to write real files instead of symlinks. 
+
+Thanks to https://github.com/netvl[@netvl] for their contributions!
+
+=== `jar:nested:` URIs are accepted by default
+
+To improve integration with Spring Boot, the Pkl evaluator by default now accepts module URIs starting with `jar:nested:` (https://github.com/apple/pkl/pull/895[#895]).
+
+The `--allowed-modules` flag (and the equally named option in other APIs) can be used to configure the set of allowed modules.
+
+== Breaking Changes [small]#💔#
+
+Things to watch out for when upgrading.
+
+=== Stricter grammar
+
+As a result of implementing a new parser, the following previously accepted grammar is no longer valid (https://github.com/apple/pkl/pull/917[#917]).
+
+==== Inline object entries
+
+When declaring multiple xref:language-tutorial:01_basic_config.adoc#entries[entries] on the same line, a semicolon is now required to separate them.
+
+The following code snippet is currently valid, and becomes a syntax error in 0.28.
+
+[source,pkl]
+----
+obj { ["one"] = 1 ["two"] = 2 }
+----
+
+To fix, insert a semicolon between the two entries:
+
+[source,diff]
+----
+-obj { ["one"] = 1 ["two"] = 2 }
++obj { ["one"] = 1; ["two"] = 2 }
+----
+
+==== String escapes
+
+When using xref:language-reference:index.adoc#custom-string-delimiters[custom string delimiters], the escape sequence becomes backslash (`\`) plus the number of pounds used to delimit the string.
+
+Due to a parser bug, any extra pounds after this escape sequence are also permitted.
+
+In Pkl 0.28, this becomes a syntax error.
+
+[source,pkl]
+----
+foo = "foo \#(bar)" // Invalid character escape sequence `\#`.
+----
+
+==== Whitespace between generator members
+
+Inline object spreads, for generators, and when generators all now require either whitespace or a semicolon separator.
+
+[source,pkl]
+----
+foo { ...bar...baz } // Syntax error
+----
+
+=== Minimum Gradle version bump
+
+The minimum Gradle version for the xref:main:pkl-gradle:index.adoc[Gradle Plugin] has been bumped to 8.2 (https://github.com/apple/pkl/pull/901[#901]).
+
+=== Minimum Kotlin version bump
+
+For users of Pkl's Kotlin libraries, the minimum Kotlin version has been bumped to 2.0 (https://github.com/apple/pkl/pull/900[#900]).
+
+=== Java/Kotlin API breaking changes
+
+Breaking changes have been made to the Java/Kotlin APIs (https://github.com/apple/pkl/pull/748[#748], https://github.com/apple/pkl/pull/749[#749], https://github.com/apple/pkl/pull/776[#776], https://github.com/apple/pkl/pull/793[#793], https://github.com/apple/pkl/pull/808[#808], https://github.com/apple/pkl/pull/810[#810]).

+
+=== Fat jars no longer shade Truffle
+
+Pkl publishes two fat jars to Maven Central: https://central.sonatype.com/artifact/org.pkl-lang/pkl-tools[pkl-tools], and https://central.sonatype.com/artifact/org.pkl-lang/pkl-config-java-all[pkl-config-java-all].
+
+Due a version bump in the Truffle library, the package `com.oracle.truffle` can no longer be shaded.
+
+For users that use both Pkl and other Truffle languages, this means that their version of Truffle should match Pkl's version.

+== 0.28.1 (2025-03-03)
+
+=== Fixes
+
+* Fixes an issue where Pkl Gradle tasks can possibly fail with `java.lang.UnsatisfiedLinkError` (https://github.com/apple/pkl/pull/995[#995]).
+* Fixes an issue where the artifacts pkl-tools and pkl-config-java-all fail with `java.lang.ClassFormatError` (https://github.com/apple/pkl/pull/998[#998]).
+
+=== Changes
+
+* Adds the ability to configure `native-image` build with Gradle system properties (https://github.com/apple/pkl/pull/1001[#1001]).
++
+Now, any system property starting with `"pkl.native"` will have that prefix stripped, and the rest passed as CLI arguments to `native-image`. For example, the native-image resource cache can be configured by passing Gradle flag `-Dpkl.native-Dpolyglot.engine.userResourceCache=/my/cache/dir`.

+- Fixes a broken "number literals" link in the 0.27 release notes (https://github.com/apple/pkl/pull/784[#784]).
+- Fixes a possible deadlock during external reader process close (https://github.com/apple/pkl/pull/786[#786]).
+- Fixes counting elements with computed indices multiple times in length computation of listings (https://github.com/apple/pkl/pull/797[#797]).

+=== Fixes

+* Fixes an issue where CLI argument `--property foo=""` is effectively parsed as `--property foo="true"`. This is now parsed as an empty string (https://github.com/apple/pkl/pull/596[#596]).
+* Fixes a regression where amending a globbed import or globbed read results in a PklBugException (https://github.com/apple/pkl/pull/607[#607]).

+
+=== Fixes
+
+* Fixes a regression where native executables fail to run on some environments that don't support newer CPU features (https://github.com/apple/pkl/pull/551[#551]).
+* Fixes a `PklBugException` when passing `.` as a project directory to `pkl project resolve` and `pkl project package` (https://github.com/apple/pkl/pull/544[#544]).
+
+=== Changes
+
+* Disable revocation checking of TLS certificates (https://github.com/apple/pkl/pull/553[#553]).
++
+As part of HTTP improvements in 0.26, we unwittingly fixed a bug where Pkl does not actually perform cert revocation checks when making HTTPS requests.
+This fix, unfortunately, caused a regression in some cases.
+For example, this happens when connecting to a server that bears a public trust certificate, while in an environment with no internet access.
+This is because the HTTP client needs to check the revocation status of all certificates in the chain.
++
+Revocation checks are a nuanced topic with some benefits, and also with its own problem areas.
+For this reason, revocation checking is disabled for Pkl's native CLIs.
+Users of Pkl's Java APIs will respect the revocation settings set in the JVM.
