latest development build indicates dev build 1.9.9.25 is also latest stable build and can be gotten from AMO, but when using Tools > Add-ons > Find Updates in Fx 2-20, only 1.9.9.22 is offered.
FYI only.

Re: AMO lagging
AMO finally has caught up. NS 1.9.9.27 popped up this afternoon. (Now, if the LDB does not change in the next few minutes, we may have reached release "sympatico"
).
On a tangentially related note, 1.9.9.27 functions well with my just-upgraded 3.6.5 (beta). Perhaps the 3.7?.?.? later this week.
