Hot on the tails of 1.6, we have an important security update and bug fix release. 1.6.1 bumps our required Django version to 1.3.1, which contains a number of important security fixes.
It also fixes the counters bug that many people have noticed in the dashboard, where the number of review requests is listed as 0 or a negative number. This was caused by an incorrect default value set when upgrading. Upgrading to 1.6.1 will fix this default, and reset the counts for all users. You should see correct values the next time you use the dashboard.
Release notes are available.
