I'll expand on this list and showcase what’s new in IDL 8.2 in a set of webinars on June 14. After you install IDL 8.2, please see the “What’s New in IDL 8.2” section linked from the main page of the IDL Help browser; it has a nice summary of the new/improved features with links to many examples. Finally (and I’m not sure I should mention this, but it’s true), there are many helpful bugfixes: I counted 25+ bugs that directly affected my work that are now fixed. In the coming weeks and months, I’ll show examples of the new and improved features in IDL 8.2, starting next week with a post about IDL’s native OPeNDAP support. Update: Registration information for the What's New in IDL 8.2 webinar is up on our Live Web Seminars page. See this more recent post for links to view the webinar recording and to download my slides and examples.
