I find extensions that broken in REL1_23 and they need backport fix from master branch. So looks like in extensions all branches, exclude master, stop progress immediately. I watch in some extensions and their REL1_22 branch stop progressing like half year ago. If I move extensions to master, then why I can't move core to master? Is master branch not safe?
