My request is that either the webpage https://www.tixati.com/news/  have a link to each version as they are released, or that there is an open listing of the contents of the folder https://download2.tixati.com/download/

The reason for this request is exemplified in this thread https://forum.tixati.com/support/1967  where people are left to either search elsewhere on the web for old versions (threat of malware) or use the link for the current version (https://download2.tixati.com/download/tixati_3.19-1_amd64.deb  --> https://download2.tixati.com/download/tixati_3.17-1_amd64.deb  should it be -1 or -0 pr -5?) and then write in a different number manually (guessing number could be wrong, is a hacky solution, and user may give up and then go look elsewhere and then get malware)

I know downgrading is not an ideal solution but it's often important in troubleshooting. And I think having a transparent official way to do this could protect some users who might then try and look at random sources on the web and then start using a malware version. This would help Tixati encourage use of safer copies of the software. One of the advantages of using a repo or ppa is the ease of downgrading. Because tixati doesn't have that a simple URL or html page could suffice.

In my case I was about to try this downgrade and found the thread .../1967. I was having a libgtk3 issue so I wanted to go back to version 3.17 which the ../news/ said is the last update before the libgtk3 upgrades. Fortunately, in my case, in guessing URLs I realised I had accidentally installed the wrong architecture 32 bit by mistake, (Doh! why didn't Ubuntu complain before I did that!?) so switching to 3.19 64 bit fixed my problem (Whew!). However, if the problem was not that simple I would have wanted to downgrade to troubleshoot. And I'm glad I didn't have to guess the hyphenated number sub version, which could have caused confusion if for example 3.17-1 had a small different bug and 3.17-2 was the best version of 3.17.

Does that make sense?

Great software, been using it for many years now. Reminds me I haven't donated in a while, will do so now.
Thanks!
