I thought maybe the "1.2.0" version number meant some new features, but I checked the CHANGES file and it's just three bugfixes; they just have an odd version numbering scheme.
They use the (fairly common) scheme where odd-numbered point releases are development and even-numbered point releases are (declared) stable, so there is actually a lot in this. Check all the "Feature:" lines in the 1.1.x versions.
