For "production work" I've been on 2.6 for a while and will soon be switching to 2.7 (I do my development on 2.7).
For my libraries I'm still supporting 2.4. The *major* syntax feature you lose by targeting 2.4 is the with statement, so it will be nice to drop 2.4 support. The next releases of mock and unittest2 will still support 2.4, but the ones after that will be 2.5+.
Thankfully tox makes testing across multiple versions (and implementations) easy.
All the best,

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
