Bruno Postle released Hugin 0.7beta5. The source code is available on Sourceforge. However it depends on a recent version of enblend, and CVS enblend is broken since the weekend. An enblend version prior to July 18 should work.
The release paves the way for inclusion in upcoming updated Linux distributions. Binaries for other systems will be made available soon.
Despite the beta5 release, bug fixing goes on at an increased pace. Gerry Patterson has not stopped working through the bug tracker and has already corrected half a dozen bugs beyond beta5.
