The 1.6.21 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. I plan to try and release on April 4th so please try and get your votes/signatures in place by April 3rd EOD. Thanks!
Please note the following known test failures (perhaps most easily triggered with APR-1.4.6): log_tests.py 30: log -g should ignore cyclic merges Can fail because 1.6.x is missing r1293229, which fixed occasionally missing merged-via notifications. diff_tests.py 32: repos-wc diff showing added entries with props Can fail because this test is missing various tweaks to account for random output order of 'svn diff' (this is independent of the APR 1.4.6 hash order problem). ruby swig test 'test_dump' Can fail because 1.6.x is missing r966458, which sorted property listings in dump files in alphabetical order, and this test does not parse dump files and sort properties for comparison.
