Thunderbird 3.1a1pre update

A while ago I posted that we were “branching” our builds and setting up 3.1x builds alongside the existing 3.0x builds to cover the mozilla-central and mozilla-1.9.1 core branches.

We have already caught and handled several regressions as a result of having just the comm-central plus mozilla-central tinderboxes up and running.

comm-central hasn’t branched yet, so the MailNews/front-end part of the 3.1x builds will be the same as 3.0x builds, but 3.1x builds will have additional core changes over the 3.0x builds.

Now for a couple of updates on my previous post:

Q. Will nightly builds be available for the new trunk (3.1a1pre)?

A. These are now available for Windows and Linux. Mac builds should be coming soon.

As of today’s builds we have now pointed the update url to our own Automatic Update Server (AUS) that will be used to check for nightly updates and manage partial update generation. So if you download today’s build (20090217) you’ll then be able to use automatic update as you can with the 3.x trees.

We’d still like testers to focus mainly on the 3.0 builds, but these are available so we can check for regressions.

Q. Where are the builds located?

The tinderbox builds are located on the “Thunderbird” (for 3.1 builds) and “Thunderbird3.0? trees. See the notes at the top of the pages for the current known issues/problems.
