"It begins," indeed.
Relax, everyone. Every release comes with a few days before DT is usable again. This is how it has always been.

Also, you may want to relax a bit longer, because with this new DF release, there will surely be several bugfix releases to follow - each of which will require a new edit to Dwarf Therapist. As much as I want to try out DF2014, I am currently waiting patiently for a (slightly) more stable version, and the DT release to match it. This may mean waiting a number of weeks to play the new version, but that's more appealing to me than the alternative of bouncing between bugfix releases and 3rd-party updates.
Seriously, it's worth the wait.
