Dear MySQL users,

MySQL Connector/Net 6.9.5 is a maintenance release for the 6.9.x series of the .NET driver for MySQL. It can be used for production environments.

It is appropriate for use with MySQL server versions 5.5-5.7.

It is now available in source and binary form from
(note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.)

Changes in MySQL Connector/Net 6.9.5 (2014-11-12)

Bugs Fixed

* Generated code that matched against the start of a
VARCHAR/CHAR column now correctly uses "LIKE" instead of
location functions for the LINQ to Entity operators
"StartsWith", "Contains", and "EndsWith". Locate
functions do not make use of indexes placed on the
VARCHAR/CHAR columns, which caused significant
performance degradation. (Bug #19783747, Bug #19680236,
Bug #19944400, Bug #72058)

* The web providers registration required the removal of
the ".v20" suffix from the type in the web providers
section in machine.config. (Bug #19715398, Bug #74080)

* Generated SQL was missing several clauses, such as
OrderBy, GroupBy, and Skip), in cases that involved the
"let" keyword, or in other scenarios that were translated
into a DbApplyExpression. (Bug #19698010, Bug #19783760,
Bug #19944549, Bug #73549)

* LINQ to Entities queries failed for the cases that
contained a predicate using IList.Contains with an
argument of "DbCastExpression, DbConstantExpression,
DbParameterReferenceExpression". (Bug #19690370, Bug
#19783755, Bug #19944528, Bug #73643)

* A SELECT query that had a nullable DATETIME field in a
child .Any() clause with an .OrderBy() would fail and
emit a NotImplementedException exception. (Bug #19681723,
Bug #19795751, Bug #70722)

* The query optimization routine would return statements
with invalid table aliases when nested queries were being
optimized. This would throw an "Unknown column"
exception. (Bug #19681348, Bug #19934324, Bug #72004)

* A memory leak was fixed. (Bug #19467233, Bug #19474480,
Bug #19474510, Bug #73122)

* The CreateUser function did not trim whitespace before
storing values into the database, while MembershipUser
did return trimmed values. The trimming is now performed
before the data is stored. (Bug #19459461, Bug #73411)

* "LINQ to Entities" queries that used Views with the Take
operator were not correctly generated. This problem
affected EF "Database First" scenarios. (Bug #19356006,
Bug #19789288, Bug #72148)
