Apache HTTP Server version 2.2.15 was released recently. It includes a number of important security and bug fixes. A changelog with further details can be found here. Thanks to Scott for notifying me about this new version.
Below you will find the 32 bit and 64 bit windows installers. Like the previous releases, the binaries have been compiled with Visual C++ 2008 (VC9). The installers and binaries are digitally signed and the signatures should appear valid as long as your Windows is up to date.
The 32 bit binaries have been tested with Windows XP and the 64 bit binaries have been tested with Windows 7.
