From my perspective, it seems positive to get an update after 1.5 months (17.26.17 to 2017.32.9ea02cb), after waiting 2.5-3.5 months between updates earlier this year. Part of that was no doubt getting the AP2 cars to functional equivalence to AP1 cars. It seems promising that we are back to converged builds that go to all cars from builds alternating between AP2 and pre-AP2 cars.
However, the change in version numbering late last year / early this year to 16/17.ww.nn (where ww was week) and recently to 2017.ww.xxxxxxx, where xxxxxxx is a hex number (build checksum???) also suggests work on the build process. Clearly work that Tesla needs to do to manage the increasing configuration diversity, but most build changes affect productivity in the short term. whatever the long term benefit.
