We have just made 3.0.0-rc2 files available. There are no truly exciting changes since 3.0.0-rc1 but this is the final release candidate before 3.0, so please test your applications with it and let us know if you find any real showstopper problems for the last chance of fixing them before 3.0.
You can get the release files, including binaries for not only MSVC but also MinGW-TDM this time, from SourceForge. More details are in the release announcement post and you can discuss this release on reddit.
