There have been quite a few changes implemented in the CodePlex version of the adapters -- a list of which follows. (List current through changeset 1827.)

- Added CheckBoxListAdapter and related WalkThru file.
- Added RadioButtonListAdapter.
- Added EmptyItemTemplate support to FormView.
- Resolved issues with and added support for all paging types to FormView and DetailsView.
- Improved method of registering CSS files to create valid XHTML markup.
- Resolved issue where DetailsView in insert mode displays EmptyDataTemplate or throws IndexOutOfRange.
- Fixed MenuAdapter registering wrong js file.
- Fixed issue when setting CssClass in a GridView RowDataBound event is ignored.

There's a few other issues that I'd like to add in to these (notably the double postback fix). All this leads me to ask a few questions...

1. Have you used any of the above releases? What's your experience with them?
2. What critical bug fixes (BUG fixes, not missing features) are outstanding?
3. What issues are stopping the current code release from being marked as the first official "1.1" community release of the adapters?

Thanks to everyone for their feedback, patches, fixes, and help!
