Quick legend:

• bold means “this was the current version when last checked, but any new version might stop working”
• italics means “last version unconfirmed, but this version works”
• ? just means I haven't checked yet.
• … means either of those:
  • this piece of software is way older than the OS, so probably the last version works
  • somehow this OS still has a long way to die, so why bother
• - means it's incompatible anyway
