Today we relaunch the Orange Squeeze beta program with a seemingly small, but important update.
2.2.0-beta1 simply adds notification controls, but there are many underlying changes to support this so it has been made a beta release. Check this link for more information about the beta program.
In related news, 2.1.11 is now/still the stable version of Orange Squeeze.
As always, check this link for complete release notes for beta and non-beta releases.
