Much has changed -- too much, in fact, to write down. The big news is that there's a standard way to write IDLE extensions; see extend.txt. Some sample extensions have been provided, and some existing code has been converted to extensions. Probably the biggest new user feature is a new search dialog with more options, search and replace, and even search in files (grep). This is exactly as downloaded from my laptop after returning from the holidays -- it hasn't even been tested on Unix yet.
