barbieq25, thanks for unlocking the thread, I'll be brief.
There is a misunderstanding regarding the nature of my request (it's not even a request, it's a good practice suggestion). I'm not asking for the old version. I'm not asking where it can be found (all that I already knew from reading the other thread).
What I am saying here is that it is usual practice to keep the one latest version for an obsolete OS available for download. Good practice. For example, if you look at Java, or Flash player, or any legacy software, you will still find a prehistoric version for download on the official website, because that version is known for being the last working version for that system, even if nobody uses that system anymore. They don't offer all versions for that generation. Only the last one, fully patched (here it would be 3.5.11). Still they will ask you to use the latest one.
This is not going against the forum rules, because the rules say "you must upgrade to the latest version". Yes. Obviously! In other words: don't try to work out an old version, don't report its bugs, don't criticize them (obviously) , and don't ask old versions to be maintained (obviously), and don't ask for a download link to random old versions somewhere in the gazillion releases (obviously).
You get my point, so I'll stop here.
Thanks for listening. Elders of the Internet, be wise.
