I do believe there was insufficient testing, but it does sound like it's been in the hopper for a long time.
Rapture Pro is significantly more efficient than Rapture on my computer.
Maybe testing was broken up in many little iterations over time and there was not a full regression before the release. I don't know. Certainly, releasing it brings about a free regression test. :-) (as long as the results don't hurt sales).
** One of the real bummers is that this may actually take best talent off other projects for damage control. And sometimes managers make choices to cut features that can't easily be fixed in order to keep other things on schedule. In general, software teams work best when not in a state of emergency. **
If I could send a message to the Bakers it would be to not flip out. Keep steady on. Improve and fix as you can. And a request to please not forget about us over the long term. I don't want this to be the last Rapture release.
