--- Comment #4 from James Hawkins truiken@gmail.com 2008-08-18 00:13:22 --- How does that make regression testing impossible? You set the good to 0.9.36 and the bad to 1.0.0 then run the test. The regression test doesn't have to be run between two consecutive versions. The document linked to in comment #1 explains the whole process.
