How are people managing TOC versions?

[Iceypop]

Hi all,

I am sorry if this stuff has been discussed I tried to do a basic Google first.

I was wondering how are people managing the various versions of their addons? Specifically if the addon works fine for TBC and Vanilla classic for example, do I really need to release a separate version that only has an updated TOC and nothing else just so it won't be reported as out of date?

It seems kind of tedious to have to create and maintain three projects for one addon, especially when you factor in keeping many different addon sites updated like here, Curse, etc.

I am in the middle of a lot of crazy RL stuff so I haven't been playing WoW and because of that I am not clued into how people are navigating this. Are we creating three separate projects and releases for each addon we have and maintaining them on all the various sites, or is there a better way (like maybe some way to define multiple versions in the TOC)
