Well, 2.0.65 was going to be tagged today and was going to be announced EOL in a year (which seems quite long to me). 2.2.25 was going to be tagged today as well but I do not see it being EOL anytime soon. There has not been a big migration to 2.4 on the Unix side, mainly because of mod_perl. I think 2.2 is safe for a couple years yet but you just never know!
