+4. Fixes failures for self-service updating of credit card credentials (issue 323)).
+5. Removes unused gross_amount parameter.
+6. Fixes a hard-coded payment processor id number, and (separately) a hard-coded payment processor type id.

+8. Provides better behaviour for recurring contributions starting after the 28th of the month (issue 276).
+9. Allow test recurring contributions to generate subsequent payments.
+10. Remove an annoying javascript warning when using FirstPay (issue 326).
+11. Prevent soap errors from exposing credit card credentials (issue 308).
+12. Improve failure handling of ACH recurring contributions (issue 301).
