The version on the Downloads page is only 1.0.20.
If you go to the Source Code tab instead and click the Download link on the right hand side you'll get the latest default branch which now has all 1.1 bits merged in up to very recently.
Most recommended option is to set up a local Mercurial enlistment so you can keep updating as new bits come in. Mostly it's all happening on the 1.x branch and that's getting merged into default quite regularly. Connection instructions are on the Source
