Today, olemarkus finally removed the dev-lang/php-5.2.17 ebuild from the gentoo-x86 tree.
So it's been nearly 5 years since php-5.2.1-r3 got introduced to the main tree. And it comes almost exactly a year after the last release of php-5.2 was announced on php.net. Half a decade lifetime is pretty decent for release cycles, ain't it?
But with all the new and shiny features in 5.3 (and 5.4!), there's really nothing bad about letting php-5.2 die.
So by all means: PHP is dead, long live PHP!
P.S.: If you find any zombies, ie packages you want to merge but that require php-5.2 to function, please notify the Gentoo PHP team via our bug tracker or leave a comment here. Thanks a lot!
