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:
