Development
builds, released once per milestone and only a few times a year, are
fairly stable, but there may be some things which do not yet work.
If you would like to try one of these milestones, we'd greatly
appreciate the assistance in testing and reporting of
issues in our issue tracker.
Nightly Builds
The bleeding
edge contains the latest and greatest new features, but nothing is
stable or guaranteed - yet. If you're using a Milestone and need a
fix, you can update to the latest Nightly, or wait for the next
Milestone.
