以下は、プラットフォーム注意事項と前回リリース以降の変更事項です。
Platform notes: * 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. * 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 HP-UX 11.23 IA64 binary package does not include the GUI bits because of problems building Qt on that platform. Changes since the last 5.1 release: Functionality added or changed: * The Windows installer now places files in a subdirectory of the 'Program Files' directory instead of the Windows system directory. * Added MSI installer for Windows 64-bit (Bug #31510) * Implemented support for SQLCancel(). (Bug #15601) * Added wrappers for missing ODBC driver manager installer functions. This makes it possible to use the driver with unixODBC 2.2.11, which is the version shipped with Debian and Ubuntu. (Bug #32685) * Disallow 'SET NAMES' in initial statement and in executed statements. * Replaced the internal library which handles creation and loading of DSN information. The new library, which was originally a part of Connector/ODBC 5.0, supports Unicode option values. * Implemented native Windows setup library * Removed monitor (myodbc3m) and dsn-editor (myodbc3c). * Replaced myodbc3i (now myodbc-installer) with Connector/ODBC 5.0 version. * Added support for SQL_NUMERIC_STRUCT (Bug #3028, #24920). * Removed non-threadsafe configuration of the driver. The driver is now always built against the threadsafe version of libmysql. Bugs fixed: * SQL statements were limited to 64k. (Bug #30983) * Diagnostics were not correctly cleared on connection and environment handles. * SQLCopyDesc() did not correctly copy all records. * Freeing a statement resulted in a memory leak due to descriptor records not being freed.. (Bug #31115) * SQL_ODBC_SQL_CONFORMANCE was not handled by SQLGetInfo(). * NULL pointers passed to SQLGetInfo() could result in a crash. * Passwords with ';' were not handled correctly. (Bug #16178) * Binding of columns between calling prepare and execute caused premature statement execution. (Bug #29239) * ADO could not open a recordset that has a DECIMAL field (Bug #31720) * SQLError() incorrectly cleared the error information, making it unavailable from subsequent calls to SQLGetDiagRec(). * ADO was unable to open record set using dynamic cursor. (Bug #32014) * SQLSetConnectAttr() did not clear previous errors, possibly confusing SQLError(). * SQLDescribeColW returned UTF-8 column as SQL_VARCHAR instead of SQL_WVARCHAR. (Bug #32161) * Fixed SQL_ATTR_PARAM_BIND_OFFSET, and fixed row offsets to work with updatable cursors. * SQLSetPos w/SQL_DELETE advances dynamic cursor incorrectly. (Bug #29765) * Recordset Update() fails in 5.1 ODBC connector when using adUseClient cursor. (Bug #26985) * MyODBC 5/ ADO Not possible to update a client side cursor. (Bug #27961) Includes changes from Connector/ODBC 3.51.21 and 3.51.22. Built using MySQL 5.0.52.
