Breaking: #73044 - JSON for ClickMenu in Backend ¶
See Issue #73044
The ClickMenu in the TYPO3 Backend now uses JSON to transport data between the server and the client.
Before, a proprietary <t3ajax> syntax with XML was used to transport the contents of the ClickMenu.
Affected Installations ¶
Installations with extensions that use custom ClickMenu.js behaviour.
Adapt the custom code to handle JSON responses instead of XML responses.
