"We just released version 2.1.2. Grab it and update your installed task version. You really should. This version fixes a nasty bug that can corrupt your data." http://taskwarrior.org/news/156 Since 2.1.1 is already stable and this version only contains bugfixes (one important), it probably should be made stable too. Reproducible: Always
We tend to wait 30 days before stabilisation, but I guess this is an exception (<=2.1.1 should be package.masked at the least).
Added to CVS and being stabilized in bug #435556.
