From time to time it seems that a new version of a software package does not work as well as the version it replaced as is the case with 2.86. Where/how can I download version 2.85 or any older version?

Here are some previous versions:

Windows 64bit
https://download1.tixati.com/download/tixati-2.85-1.win64-install.exe
https://download1.tixati.com/download/tixati-2.84-1.win64-install.exe

Linux 64bit
https://download2.tixati.com/download/tixati-2.85-1.x86_64.rpm
https://download2.tixati.com/download/tixati-2.84-1.x86_64.rpm

https://download2.tixati.com/download/tixati-2.85-1.x86_64.manualinstall.tar.gz
https://download2.tixati.com/download/tixati-2.84-1.x86_64.manualinstall.tar.gz

Thanks for your reply janet. I wonder if it might be possible to make the archive accessible/browserable without knowing the full name of a previous release?

Also, for linux the deb files download?

Here are the deb files for you:

https://download2.tixati.com/download/tixati_2.84-1_amd64.deb

Tixati v2.87 was released

Requesting some way to access old versions for download. There should really be a central location where they're accessible.

The links above no longer work (which highlights the unreliable nature of such things), but in any case I'm looking for versions 3.16-3.30.

This option will be great to have!
Becuase of tihs reason I always must have and keep old good versions on my mashine. :-/

I completely agree! I try to store all versions on my FTP, but my script is not perfect and sometimes I lose some versions =(

I can send you versions from 3.16-3.29, 3.30 has not been released, as far as I know, as well as a number of others.
