1.5.9 tarballs are up for testing and signing. The magic revision is r1041577: http://people.apache.org/~hwright/svn/1.5.9/
To sign the release, please input your signatures using the script here: http://work.hyrumwright.org/pub/svn/collect_sigs.py (The script worked pretty well for 1.6.15, but if you discover any bugs please let me know.) Testing by enthusiastic users is also welcomed (but remember that this is not yet a blessed release, with all that that implies). If you are a package maintainer, please do not included this release in your distribution until after it has been formally released. I'd like to collect all the signatures in time to do a release by December 6. -Hyrum
