Mercurial 2.8 has been released.

The changes aren't as sexy as previous releases. But there are a handful of bug fixes that seem useful to pull in. People may also find the new shelve extension useful.

I encourage Mozillians to keep their Mercurial up to date. I once went around the San Francisco office and stood behind people as they upgraded to a modern Mercurial. For the next few weeks I was hearing a lot of "OMG Mercurial is so much better now." Don't handicap yourself by running an older, buggy Mercurial.

If you don't yet feel comfortable running 2.8, 2.7 should be safe.
