Tor browser is the user facing part of Tor and thus the tor-browser-bundle tag attracts lots of questions. However over the time this Q&A page exists we saw the major versions 3, 4 and 5 of TBB. Some versions got new features and maybe older features won't work anymore. So I was thinking if we could introduce a TBB-version-tag. This shows which major version is used and we can easily see if one uses an outdated version.
What do you think about this approach? What should the tag look like?
