The torrent of milestones consists of just that... very stable versions of Tixati that lasted at least 6 weeks before being superceded/replaced.
V2.28 didn't last even 2 weeks before it was replaced, by v2.29, which didn't last even 24 hours before a disruptive bug was detected requiring a quick fix as v 2.31.
That version held for nearly 2 months while the next version with major changes was being developed, to be released as v 2.33. As expected, once this general release was made, lots of issues that were not uncovered during the extensive 'alpha' testing became apparent and quick-fix v2.34 was released. Given that 10+ days have passed with I think only a couple new minor? issues being revealed (trackers failing to merge
http://forum.tixati.com/support/2292/ and a situation of case sensitivity
http://forum.tixati.com/support/2309/ ), v2.34 may well turn out also to have the longevity of the other milestones selected for that torrent collection, unless the DEVs decide on releasing another quick bug-fix version for those and any other minor issues they have become aware of.
As you, I would prefer a page listing links for all prior versions along with the signature keys for linux version verification. Windows installers are self-verifying.

But there are simple workarounds to download the earlier versions such as the list Zarkbit posted in the thread you mentioned in your original post which provided the links for versions 1.46 to 2.25. Any version after v2.25 is available by copying the URL and changing 1 or 2 digits as needed.
iow, changing the 25 to 33 in
http://www.tixati.com/download/tixati-2.25-1.win32-install.exe becomes
http://www.tixati.com/download/tixati-2.33-1.win32-install.exe . If you want v2.31, then change the 25 to 31 and download away.
