I work on major releases at the same time I work on incremental releases, but I only concentrate on one at a time, and major releases won't go forward if there are a substantial number of incremental things that need looking after. In other words, major feature stuff has been on hold pretty much continuously since early February, which is when I began working on the Tiger transition. After releasing SS 2.1, I immediately began working on the 2.1.1 update, and I'm about ready to rock a 2.1.2 release. After that, it looks like major release code'll be back on the front-burner again.

Actually, I have worked on major release stuff since February, but only when my brain has needed a break from the mundaneness of bug fixing - probably under 20 hours total, versus probably 1000 hours for Tiger and bug fixes.

Mmmmmwwwhy do ya ask?
