We’ve recently made some changes to the Thunderbird try server so that now we’re able to push comm-central and mozilla-central patches and have them tested against Thunderbird.
This means that we can test proposed patches against mozilla-central on all our supported platforms and have our standard tests run against them. To use this functionality, you need to include a specially named mozilla-central patch file in your push to try-comm-central, detailed instructions can be found here.
This functionality also works with the other repositories that comm-central pulls, again see the instructions for details.
