The 1.9.0-rc1 release artifacts are now available for testing/signing. Please get the tarballs from https://dist.apache.org/repos/dist/dev/subversion and add your signatures there.
This being a rc1 it means that our soak period for 1.9.0 has begun as described here: http://subversion.apache.org/docs/community-guide/releasing.html#release-stabilization
