I'm very sad to see them drop support for 32-bit, since that is the computer on which I have been using Debian for the past 10 years...
Does anyone have any suggestions for a 32-bit distro that's still being updated?
Gentoo still supports it but depending on what you want, compile times with modern compilers on old hardware are a pain.
Linux mint technically still does, perhaps because they’re lagging behind Debian. AntiX does but that has its own tradeoffs. With full potential respect for your situation, if you’re not able to obtain 64 bit hardware, there’s nothing that wrong with not upgrading your OS for now
