So with the upcoming release of Mac OS X 10.5, we've made a choice that is going to make some folks unhappy. We are dropping support for Mac OS X 10.3. For us, this is driven by adoption rates, we see about 9% of our users still using 10.3 and that number has been dropping rapidly in the last few months. The reason, is that we are starting to use some newer features in the Apple development environment, and those features are not supported on 10.3 or older.
So, while some of our work *may* still work on 10.3 after October 1, none of it will be officially supported on 10.3.
