Although LibreOffice 7.4 has reached EOL, the online version of the API reference is still at version 7.4. https://api.libreoffice.org/ needs an update to at least 7.5, better to 7.6.

Thank you Regina, confirmed and Cloph said it's on his to-do list. CC-ing him in.
It is now at version 24.2. That is better than the reported 7.4. But it is still behind the current version. The end-of-life for 24.8 and release of 25.8 should be a trigger for updating the SDK. In general, a new release should always update https://api.libreoffice.org/ too.
Moving it to https://redmine.documentfoundation.org/issues/3838
