This coming week, we'll be putting out new stable releases for 0.2.9 and later supported branches to fix a few security bugs. The highest-severity bug to be fixed is severity "medium". (See https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/Security... for information about how we rank security issues.)
These releases will also backport the anti-DoS features from Tor 0.3.3.
Relays and authorities should be sure to upgrade once packages are available; these issues are not high-priority for clients.
Thanks for the heads-up.
Since you specifically mentioned new **stable** releases and alpha branches have been treated differently in the past I was wondering whether this affects 0.3.3.x as well and if it will get an update on the same date or if 033 is not affected.
And since you excluded 025LTS (supported until 2018-05-01) I assume it is not affected.
