OpenOCD 0.5.0 has been released. Here is the News.
Source zip archive or tar ball can be downloaded from SourceForge.
Windows binaries (32bit and 64bit, cross build under Linux with MinGW-w64 project's compiler) can be downloaded from Freddie Chopin's website.
You can also use my test build which is native Windows build using 32bit MinGW.org toolchain.
Take note due to GPL licensing reasons, these Windows binaries are linked against libusb-win32 and libftdi and not the proprietary FTDI D2xx library.
