• PHP 8 support was added. There is no functional change to the library, just the platform dependency in composer.json was updated to allow the library to be installed with PHP 8.

• Some new filters were introduced. See the filters and actions documentation for all the details.

• The block_editor argument was introduced.

• The post_author filter now accepts an options array or callback.

• Two new post type listing screen filters were introduced: post_author for an author dropdown, and post_date for a date picker.
• The title_icon and title_cb parameters were introduced for displaying a Dashicon or complex markup in post type listing screen column titles.
• The dashboard_activity argument was added to allow the post type to be included in the Recently Published section of the Activity widget on the dashboard.

• It's now possible to specify a default argument in a filter, so posts are filtered by that value by default.
• A meta_key_exists filter type has been introduced, which performs a real EXISTS query on the meta key rather than the truthy meta value query that the meta_exists filter performs.

• An optional label argument can now be passed to most filters to control the text used for the <label> element for the field. A sensible default is used depending on the filter type, and it's unlikely you'll need to change this.

• Any value that can be passed through strtotime() can now be used when using an admin column that uses date_format. Previously this was restricted to just Unix and MySQL format timestamps.
