Unfortunately, we don’t have a directory of all apps/versions that are available. Having said that, Github is a reliable source for what apps are available for the most part:
tk-multi-importcut is an old Studio tool, so it’s no longer available at large: we do give access to the raw code to some former Studio clients, but the repo is private, and it’s not available from the app store in normal cases.
Having said that, while the list of apps is accurate via github repos, the tags aren’t always: we may release a version of an app or engine (say,
v1.0.2), then discover a bug (hopefully this happens infrequently!) and have to roll back, say to
v1.0.1. In a case like this, you may see
v1.0.2 in the Github tags and in the release notes, but if you run
tank updates, you’ll get
v1.0.1. Internally, we have access to this information (ie, which versions have been marked as faulty, etc.), but unfortunately we don’t have a public place for that info at this time.
Hope that clears up any confusion. Let me know if you have any other questions.
