CHANGELOG.md

 - Removed `CraftCms\Cms\Condition\Contracts\ConditionRuleInterface::getHtml()`. `getForm()` must be implemented instead. ([#19588](https://github.com/craftcms/cms/pull/19588))
 - Removed `CraftCms\Cms\Element\Conditions\Contracts\ElementConditionRuleInterface::getExclusiveQueryParams()` and `modifyQuery()`. `ElementQueryConditionRuleInterface::modifyQuery()` should be implemented instead, which now accepts the underlying query builder directly. ([#19563](https://github.com/craftcms/cms/pull/19563))
 - Removed `CraftCms\Cms\Element\Conditions\ElementCondition::$queryParams`. ([#19563](https://github.com/craftcms/cms/pull/19563))
+- Fixed a bug where condition builders passed raw condition values to form change listeners. ([#19774](https://github.com/craftcms/cms/pull/19774))
 
 ### Fields
 - Added a “Default Row Values” setting to Table fields. ([#3621](https://github.com/craftcms/cms/issues/3621))
