5.3.5
Security Notes:
* Connector/ODBC 5.3.5 Commercial upgrades the linked OpenSSL

as not vulnerable to CVE-2015-0286
(http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0286).
Since the only change in Connector/ODBC 5.3.5 is the inclusion
of OpenSSL libraries publicly reported as unaffected by
CVE-2015-0286, and since Oracle-produced MySQL Community
builds use YaSSL libraries which have been reported as not
affected by CVE-2015-0286, Oracle will not produce builds for
Connector/ODBC Community for version 5.3.5. This means the
Community edition of Connector/ODBC will skip version 5.3.5.

were set to " " instead of an empty string. (Bug #30568)
* Fixed incorrect input requirement in the setup dialog. (Bug #30499)

columns without bound data buffers. (Bug #31246)
----
3.51.20 (7-Sep-2007)

Optimize Column Width"), which was removed from the driver in 3.51.18.
* The wrong column size was returned for binary data. (Bug #30547)

----
3.51.19 (8-Aug-2007)
Functionality added or changed:
* Because of Bug #10491 in the server, character string results were

* An experimental binary package, without an installer, is available
for Microsoft Windows x64 Edition.
* Binary packages as disk images with installers are now available
for Mac OS X.
* Binary packages for Sun Solaris are available as PKG packages.
* Added FLAG_MULTI_STATEMENTS to allow issuing queries that contain
multiple statements. Also added to the setup GUI. (Bug #7445)
* Removed support for the TRACE and TRACEFILE DSN options. The standard
ODBC logging should be used.
* Added support for SQL_ATTR_ROW_BIND_OFFSET_PTR in normal cursors.

were often incorrect. These lengths should now conform to the ODBC
specification. FLAG_FIELD_LENGTH no longer has any effect. The default
behavior was incorrect. (Bug #27862)
* The SQL_DATA_TYPE column in SQLColumns() results did not report the
correct value for date and time types.
* The SQL_DATETIME_SUB column in SQLColumns() was not correctly set for
date and time types.

for decimal values in MySQL 5.0 and later.

fields.

* The wrong value for DECIMAL_DIGITS in SQLColumns() was reported for
FLOAT and DOUBLE fields, as well as the wrong value for the scale
parameter to SQLDescribeCol(), and the SQL_DESC_SCALE attribute
from SQLColAttribute().
* MySQL BIT(n) fields were always treated as SQL_BIT data. When n > 1,
