Changes for version 2.011
- bump to stable release
Changes for version 2.010_01
- Had error_* methods to get the error text and check the error conditions so you don't have to use %ERROR_TEXT or the constants.
- Deprecate the xisbn stuff. It's still there, but it should have disappeared about two weeks ago.
- Add an example of inserting an unofficial group code for the Blake and Taylor shenanigans.
