 git merge v2.9.2                                                              [19:50:38]

CONFLICT (content): Merge conflict in src/Microdown-Blog-Tests/MicBridge.class.st
Automatic merge failed; fix conflicts and then commit the result.

I do not really understand why there is a conflict. So I will wait for some help.
