Apache HTTP Server 2.2.16 was released day before yesterday that is 25th July 2010. And here are the 32 and 64 bit Windows binaries that I compiled. They have been compiled with Visual C++ 2008 (VC9) and contain the latest versions of openssl (1.0.0a) and zlib (1.2.5).
As before, the installers and binaries are digitally signed. The signatures should appear valid if you are using Windows 7 or 2008 or your Windows is up to date.
