As we move from SVN to Git I'm hoping to add real git "Tags" (symbolic names for commits) so that we can get descriptive names (using "git describe") for every possible point in the repository.
Currently, because SVN supports tags being a sort of branch-with-little-intent-to-change ... it is not a valid mapping to the Git concept. Therefore our Git repo has actually zero real 'tags'. However, tags are very useful to navigate and define featured points within the tree of commits over time. Nothing substantial should change in any other way. * CH
