Looks like [IDL 8.2.1] is ready:
> IDL 8.2.1 will be released next Wednesday, October 3. It includes updates to, primarily, (New) Graphics, the widget toolkit and the Workbench. I’ll have a more detailed listing, along with a link to download a set of programmatic examples, in a post next week.
From the version number I'm guessing this will be mostly bug fixes, but Mark does mention the addition of [Brewer] color tables!
