implement workaround for openssl regression (fixes #981)

The introduction of the `-multi` option to the x509 subcommand
introduced a regression to the `-checkend` behaviour, preventing
openssl to correctly indicate the certificate expiry status via
its exit code.

This commit introduces a (maybe temporary) workaround by instead
checking the output string.

 # Change Log
 This file contains a log of major changes in dehydrated
 
+## [x.x.x] - xxxx-xx-xx
+## Added
+- Added a configuration parameter to allow for timeouts during domain validation processing (`VALIDATION_TIMEOUT`, defaults to 0 = no timeout)
+
+## Changed
+- Only validate existance of wellknown directory or hook script when actually needed
+- Also allow setting `KEEP_GOING` in config file instead of relying on cli arguments
+- Allow skipping over OCSP stapling errors, indicate that some CAs no longer support OCSP
+- Throw error with information about OCSP deprecation if certificate doesn't indicate OCSP support
+
+## [0.7.2] - 2025-05-18
+## Added
+- Implemented support for certificate profile selection
+- Added a configuration parameter to allow for timeouts during order processing (`ORDER_TIMEOUT`, defaults to 0 = no timeout)
+- Allowed for automatic deletion of old files (`AUTO_CLEANUP_DELETE`, disabled by default)
+- Added CA presets for Google Trust Services (prod: google, test: google-test)
+
+## Changed
+- Renew certificates with 32 days remaining (instead of 30) to avoid issues with monthly cronjobs (`RENEW_DAYS=32`)
+
+## Fixed
+- Changed behaviour of `openssl req` stdin handling to fix compatibility with OpenSSL version 3.2+
+
+## [0.7.1] - 2022-10-31
+## Changed
+- `--force` no longer forces domain name revalidation by default, a new argument `--force-validation` has been added for that
+- Added support for EC secp521r1 algorithm (works with e.g. zerossl)
+- `EC PARAMETERS` are no longer written to privkey.pem (didn't seem necessary and was causing issues with various software)
+
+## Fixed
+- Requests resulting in `badNonce` errors are now automatically retried (fixes operation with LE staging servers)
+- Deprecated `egrep` usage has been removed
+
+## Added
+- Implemented EC for account keys
+- Domain list now also read from domains.txt.d subdirectory (behaviour might change, see docs)
+- Implemented RFC 8738 (validating/signing certificates for IP addresses instead of domain names) support (this will not work with most public CAs, if any!)
+
 ## [0.7.0] - 2020-12-10
 ## Added
 - Support for external account bindings
