Confluence 9.5 LESS not transforming

Hey,
we started testing the Confluence 9.5.0-rc1 build and as we installed our plugins we saw that most of our less which should be transformed by the less-transformer plugin was not transformed. Does anyone else run into this problem?
I couldn’t find any changes in the 9.5 changelog that lead to an answer for this problem.

Best regards
Florian

Update: Made a quick test against the just released 9.5.1 version, still not working.

See https://developer.atlassian.com/server/framework/atlassian-sdk/updates/less-transformer/removal/ about the Less transformer removal announcement.

The timeline states that it reaches EOL with 9.2 and “By the end of 2025, we’re removing the Less web-resource transformer from all Data Center products in their next major versions: Jira Software 11, Jira Service Management 11, Confluence 10, Bitbucket 10, Bamboo 11, and Crowd 7.” so I guess a minor update should still not break apps compatible with previous versions like 9.4 or 9.2
