 ## [2.0.0] - 2023-12-28
+### Added
+* Tested against PHP 8.3. [#138], [#150]
+
 ### Changed
 * All the source classes are now namespaced under `Yoast\WHIPv2`. The version number in the namespaced will be bumped up with every major version. [#157]
     The classes have also been renamed to remove the `Whip_` prefix, and the folders' names have been capitalized to follow the PSR-4 standard.
 * The `Requirement` interface now explicitly declares the following two additional methods: `version() ` and `operator()` and classes implementing the interface should ensure these methods are available. [#146]
 * General housekeeping.
 
-### Fixed
+### Removed
+* The deprecated `Whip_WPMessagePresenter:register_hooks()` method has been removed. [#158]
 
+### Fixed
 * Compatibility with PHP >= 8.2: prevent a deprecation notice about dynamic properties usage from being thrown in the `RequirementsChecker` class. [#117]
