Platform specific notes:
Important Change: You must uninstall previous 5.1.x editions of MySQL Connector/ODBC before installing the new version.
The HP-UX 11.23 IA64 binary package does not include the GUI bits because of problems building Qt on that platform.
There is no binary package for Mac OS X on 64-bit PowerPC because Apple does not currently provide a 64-bit PowerPC version of iODBC.
The installer for 64-bit Windows installs both the 32-bit and 64-bit driver. Please note that Microsoft does not yet supply a 64-bit bridge from ADO to ODBC.
In previous versions, the SSL certificate would automatically be
verified when used as part of the MySQL Connector/ODBC connection. The
default mode is now to ignore the verificate of certificates. To
enforce verification of the SSL certificate during connection,
SSLVERIFY DSN parameter, setting the
value to 1.
Inserting characters to a UTF8 table using surrogate pairs would fail and insert invalid data. (Bug#34672)
Installation of MySQL Connector/ODBC would fail because it was unable to uninstall a previous installed version. The file being requested would match an older release version than any installed version of the connector. (Bug#34522)
SqlGetData in combination with
SQL_C_WCHAR would return overlapping data.
Descriptor records were not cleared correctly when calling
The dropdown selection for databases on a server when creating a DSN was too small. The list size now automatically adjusts up to a maximum size of 20 potential databases. (Bug#33918)
Microsoft Access would be unable to use
DBEngine.RegisterDatabase to create a DSN
using the MySQL Connector/ODBC driver.
MySQL Connector/ODBC erroneously reported that it supported the
functions for parsing values in SQL statements, which could lead
to bad SQL generation during a query.
