Correct. Until the release has been announced, that directory should be considered a
branch. After that is a tag set in stone. I admit I took a shortcut by merging the
change. The correct way should have been:
* create a new branch from lazarus/tags/lazarus_0_9_26_2 to
lazarus/branches/lazarus_0_9_26_2
* delete lazarus/tags/lazarus_0_9_26_2 (since the tag is not valid anymore)
* merge the revision from trunk to lazarus/branches/lazarus_0_9_26_2
* tag lazarus/branches/lazarus_0_9_26_2 to lazarus/tags/lazarus_0_9_26_2
Again: cumbersome.
I am abusing the tool, because it is a tool after all, not a law. Sorry to confuse
you with it, but I never realized you would get into trouble with git. svn export
and svn co of that tag works exactly the same after the release announcement (all
the release builders were notified in private).
