Second beta-test release of the 7.x version of the API module -- several issues have been fixed since the first beta release. It's closer to ready for release, but there are still some known issues. Check the API module issue queue for an updated status, and please report any problems you see that aren't already there.
You might be better off trying the 7.x-1.x-dev release instead of this Beta, which is likely more up-to-date (or better yet, using Git version control to get the most up-to-date version).
This releases fixes two minor bugs in caching and form validation. If you have an iDEAL setup that runs well, you don't need to upgrade. The fixes only prevent some possibly unexpected behavior when configuring iDEAL API.
