More resources have been allocated to the Connectors team at MySQL and most of them are focused on either C/ODBC v3 bug fixs or C/ODBC v5 development.
The folks working on C/ODBC v3 have been knocking off bugs at speedy pace. The Engineering team have been lending their time as well by taking over the build-to-release process. Still others are working on improving QA by adding new tests and creating a new automated process to run them.
This work has resulted in a new release of C/ODBC v3.
