 - Improved the performance of the “Generating pending image transforms” queue job. ([#12274](https://github.com/craftcms/cms/issues/12274))
 - Added more reserved field handles to avoid conflicts with `craft\base\Element` properties. ([#12577](https://github.com/craftcms/cms/issues/12577))
+- Control panel requests no longer override the `pageTrigger` config setting value to `'p'`. ([#12598](https://github.com/craftcms/cms/issues/12598), [#12614](https://github.com/craftcms/cms/pull/12614))
 - Fixed field status badge styling in some contexts. ([#12403](https://github.com/craftcms/cms/issues/12403))

 - Fixed a bug where cancelling a conflicting volume folder move would result in the moved folder getting deleted.

 - Fixed a bug where element indexes could stop showing their loading spinner prematurely if the element listing needed to be reloaded multiple times in rapid succession. ([#12595](https://github.com/craftcms/cms/issues/12595))
 - Fixed a bug where element indexes would show show an expand/collapse toggle for structured elements that only had unsaved draft children, which aren’t actually shown. ([#11253](https://github.com/craftcms/cms/issues/11253))
 - Added `craft\helpers\Db::escapeForLike()`.
+- Added `craft\web\twig\variables\Paginate::$pageTrigger`. ([#12614](https://github.com/craftcms/cms/pull/12614))
 - `craft\services\Assets::getAllDescendantFolders()` now has a `$withParent` argument, which can be passed `false` to omit the parent folder from the results. ([#12536](https://github.com/craftcms/cms/issues/12536))
 - Deprecated `craft\helpers\DateTimeHelper::timeZoneAbbreviation()`.
 - Deprecated `craft\helpers\DateTimeHelper::timeZoneOffset()`.
