A few hours ago I've concluded a 2 month long release process of PHP 5.2.7 that been over 6 months in the making. Hurrah
As you can imagine, from the extended timeline, the bug fix list is quite long, in fact there are over 170 different bug fixes in just about all of the extensions and code paths, so hopefully 5.2.7 will be the most stable 5.2 release to date. There are also just over a half dozen security fixes, so you should take a look and see if they affect your PHP use cases.
The official release announcement can be found
here and for those of your bored enough a full change log is also
available.
As usual a big thanks to all of the developers who has spent the time investigating and fixing bugs and all the folks who reported them as well, especially the ones keep an eye on the security stuff.
