Btw, NO breaking changes obviously does not work for security issues, but in my opinion this is not a security issue.

So the idea would be to say that going forward all plugins have to be compatible with 4.6.1 instead of 4.6.0? Also not ideal. In my opinion, this is a breaking change in a major release. I agree that the original bugfix had to be fixed, but this is now two breaking changes instead of one. So from a compatibility standpoint, the commit needs to be reverted even if that leaves the issue in 4.6.0. And 4.6.1 needs to be taken off the site. 

The mandate has been and always was, that there are NO breaking changes in major. No matter if they fix things or introduce new things. From a reliability point of view and a "being a good partner to the industry" point of view, this is critical and needs to be reverted

Could you add a bug-report for this? In my pov, this is a critical bug and should be addressed by 4.6.2. It might even be considered severe enough for a recall of 4.6.1. A lot of companies use our plugin structure and if this is an issue, that is a dealbreaker for a lot of them

It's definitely not good, although that fix was needed to solve a crasher that was introduced in the 4.6.0 dev cycle. While the proper thing to do was likely to revert the offending commit instead of backporting the fix, at this point I am unsure about the best way to fix it. If there has been more than one 4.6.x release before the incompatibly it would be somewhat different, but now either way there will be exactly one 4.6 release not compatible with the others.
