Today's release of Power Pack 2.0.1 is a small bug fix and maintenance release.
The primary fix addresses various access issues with repositories hosted on Bitbucket Server and Visual Studio Team Services when transitioning license states (such as from a valid trial license to an expired one), which can cause future problems for users who need to use these repositories.
We've also dropped support for Python 2.6, allowing us to focus on bringing Python 3.x support to both Power Pack and Review Board in future releases. Python 2.6 hasn't been maintained in years, and support was recently dropped in Review Board 3.0. The last release to support Python 2.6 is Power Pack 2.0.
If you're still on Python 2.6, we can help you upgrade.
Power Pack 2.0.1 is recommended for all Power Pack users, particularly those using Bitbucket Server and Visual Studio Team Services. Power Pack 2.0.1 supports Review Board 2.5 and up on Python 2.7.
