Several code issues identified by Fortify were corrected. (WL #11829)
Refactored codebase to remove legacy code and implement general performance improvements. For example, unused ANSI data conversion code and legacy functions were removed. Example improvements affect bookmark handling for bulk operations, handling of memory buffers for prepared statements, and handling of session variables. (WL #11994)
On Windows, 32-bit support was added and 32-bit binaries are now available. (WL #12139)
An RPM package for installing ARM 64-bit (aarch64) binaries of Connector/ODBC on Oracle Linux 7 is now available in the MySQL Yum Repository and for direct download.
Known Limitation for this ARM release: You must enable the Oracle Linux 7 Software Collections Repository (ol7_software_collections) to install this package, and must also adjust the libstdc++7 path. See Yum's Platform Specific Notes for additional details.
Added checks for unsupported functionality that return SQL_ERROR instead of SQL_SUCCESS, where the error message refers to the unsupported functionality. (Bug #28217387)
The data source dependent type's name was not always returned. For example, the ODBC driver reported TEXT as the database type for TINYTEXT, MEDIUMTEXT, and LONGTEXT, and reported BLOB for TINYBLOB, MEDIUMBLOB, and LONGBLOB. (Bug #11761407, Bug #53900)
