Introduction

What regressions have we had, and what was their causes?

• notest: we had no test for something that used to work (e.g. oversight, testing in layers, whatever). It does not imply that a test could reasonably have been predicted to be needed.
• badtest: We had a test but it didn't test well enough or some such.
• yuiupgrade: upgrading yui broke things (and we didn't notice)
• jsmigration: ajaxifying/jsifiying things didn't preserve pre-js behaviours.
• ops: The issue was outside Launchpad and we don't know the cause / leadup. May imply notest.
• unknown: The cause of the regression is not yet known.
• sideeffect: The regression was a sideeffect of some other change.
• bzrupgrade: The issue is because of a change in bzr.
• testdisabled: We had a test but it was disabled.
• integration: Breakage when things were integrated (e.g. version mismatches)
