On his blog today Gopal Vijayaraghavan has posted about the release of the latest version of the APC sofware (Alternative PHP Cache) - version 3.1.2.

Finally, after nearly a year of work, it's into a release. Some new stuff has sneaked into it undocumented, that people might find interesting - apc.preload_path would be one of them. The backend memory allocation has been re-done - the api part by me and the internals by shire. There's a hell of a lot of new code in there, both rewritten and added. Tons of php4 cruft removed, php5 stuff optimized, made more stable, then less stable, made faster, then applied brakes. Made leak-proof, quake-proof and in general, idiot-proof. So, on & so forth.

To show the difference, he includes a diff of the current version against the previous - 68 files changed, 3255 insertions and 5545 deletions.
