Got the release out after more struggling with ssh on windows and a last minute fix to the quvi support.
The downloads.kitenet.net git annex repository had accumulated 6 gb of past builds that were not publically available. I am publishing those on the Internet Archive now, so past builds can be downloaded using git-annex in that repository in the usual way. This worked great!
I have ordered a CubieTruck with 2 gb of ram to use for the new Arm builder. Hosting still TBD.
Looks like git-annex is almost ready to be included in stackage, which will make building it from source much less likely to fail due to broken libraries etc.
