Dear MySQL users,

MySQL Connector/ODBC 5.1.1-beta, a new version of the ODBC driver for
the MySQL database management system, has been released. This release
is the first beta (feature-complete) release of the new 5.1 series and
is suitable for use with any MySQL server version since MySQL 4.1,
including MySQL 5.0, 5.1, and 6.0. (It will not work with 4.0 or
earlier releases.)

Keep in mind that this is a beta release, and as with any other
pre-production release, caution should be taken when installing on
production level systems or systems with critical data.

The release is now available in source and binary form for a number of
platforms from our download pages at

and mirror sites. Note that not all mirror sites may be up to date at this
point in time, so if you can't find this version on some mirror, please try
again later or choose another download site.

We welcome and appreciate your feedback, bug reports, bug fixes, patches,

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
* 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
* 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.
