According to the official git docu "
Like most VCSs, Git has the ability to tag specific points in history as being important. Generally, people use this functionality to mark release points (v1.0, and so on)."
So, yeah, it would allow for Daniel's interpretation, which I indeed share. But looking at actual usage, my completely unrepresentative survey confirms that they are used for marking releases and releace-candidates mostly. I couldn't find a single instance where they use it for, well, tagging a specific version for anything else.
It seems that a number of widespread tools are also assuming this usage. I would have suggested to take this to the weekly meeting to discuss, but since we already spend sufficiently time here on the topic I would suggest to
* switch to tags for releases
* think about our release strategy
* use either a branch for demo or just take the commit-hash
OK?
Cheers,
