This means you can have multiple view controllers efficiently share a single resource! *(See [Observing changes and notifications](#observing-changes-and-notifications))*

 - **Free to name entities and their class names independently.** CoreStore gets around a restriction with other Core Data wrappers where the entity name should be the same as the `NSManagedObject` subclass name.

 Starting CoreStore 4.0, we can now create persisted objects without depending on *.xcdatamodeld* Core Data files. The new `CoreStoreObject` subclass replaces `NSManagedObject`, and specially-typed properties declared on these classes will be synthesized as Core Data attributes.

 ```
 The property names to be saved to Core Data is specified as the `keyPath` argument. This lets us refactor our Swift code without affecting the underlying database. For example:
 ```swift
 class Person: CoreStoreObject {

 # Changesets
 ### Upgrading from 3.x.x to 4.x.x
 **Obsoleted**
 - `LegacySQLiteStore` is now finally obsoleted in favor of `SQLiteStore`. For sqlite files that were created previously with `LegacySQLiteStore`, make sure to use the `SQLiteStore.legacy(...)` factory method to create an `SQLiteStore` that can load the file from the legacy file path.
 - `SQLiteStore.init(...)`'s `mappingModelBundles` argument is now obsolete. The new initializer accepts a `migrationMappingProviders` optional argument where explicit mapping sources are declared. For reference on how to do this, read on [Custom migrations](#custom-migrations).
 **Deprecated**
 - `DataStack.beginAsynchronous(...)`, `DataStack.beginSynchronous(...)`, `AsynchronousDataTransaction.commit(...)`, and `SynchronousDataTransaction.commit(...)` are now deprecated in favor of `DataStack.perform(asynchronous:...)` and `DataStack.perform(synchronous:...)` family of methods. These new `perform(...)` methods are auto-commit, meaning the transaction automatically calls `commit()` internally after the transction closure completes. To roll-back and cancel a transaction, call `try transaction.cancel()`. Read [Saving and processing transactions](#saving-and-processing-transactions) for more details.
 **Other Changes**
 - `ListMonitor.refetch(...)` now works by recreating its internal `NSFetchedResultsController`. Previously `refetch(...)` would only apply new `FetchClause`s on top of previous fetches. Now all `FetchClauses` are required to be passed to `refetch(...)` each time it is called.
 - New important concepts on "Dynamic Models", "Schema", and "Schema Histories".
    - **Dynamic Models** (`DynamicObject` protocol): These are Core Data object types that any `NSManagedObject` or `CoreStoreObject`s conform to. *(See [Type-safe `CoreStoreObject`s](#type-safe-corestoreobjects))*
    - **Version Schema** (`DynamicSchema` protocol): These types contain info for a single model version, as well as entities that belong to it. Currently supports `XcodeDataModelSchema` (*.xcdatamodeld* file), `CoreStoreSchema`, or `UnsafeDataModelSchema`. *(See [Migrations](#migrations))*
    - **Schema History** (`SchemaHistory` class): This is now the preferred way to express all models to the `DataStack`. This class contains info to all the `DynamicSchema` across multiple model versions. *(See [Migrations](#migrations))*
