For the TraceMonkey and Electrolysis projects we’ve had a problem with nightly updates sending people back to mozilla-central builds. Nightlies produced from April 1st onwards (yes, really!) no longer had that issue but weren’t getting the latest build. Now I’m happy to tell you that updates will be offered to the latest nightly build for those branches, so you can get the newest JavaScript or process separation fixes automatically. It works just like other nightly and release updates, and we can do the same for any project branch that produces nightly builds.

And if you are one of the lost souls who have a Firefox 4.0a1pre build from March – May 2008, when mozilla-central used that version before dropping down to 3.1a1pre, then welcome to 2010 and all the great changes in mozilla-central since 2008.
