Upgrading to 0.21.1

This is a bug fix release that requires no changes to your code.

Included in this release is a fix for some database cursors where we would force Cursor.execute and Cursor.executemany to return a cursor instead of the originally intended output. This caused an issue specifically with MySQL libraries which tried to return the row count and we were returning a cursor instead.
