This isn't exactly right.
Recent releases have 18 months of "support" (meaning, bug fixes are
backported), and then another 18 months of "security backports", which
means only XSAs are backported [1], regardless of when or how many
releases have been made. It just happens that most releases recently
have ended up taking about 9 months, which means at any given time you
have 2 in 'active support'; but that's mostly a coincidence. :-)
So 4.4 won't be getting any more point releases, but it should
continue to get XSAs through March 2017. (This table [2] has it
ending in March 2016, but I'm pretty sure that's a mistake.)
