MySQL Connector/Net 6.7.4 发布了，下载地址：http://dev.mysql.com/downloads/connector/net/6.7.html
这是一个稳定版，修复了如下 bug：
The installation of "MySQL for Visual Studio 1.0.2" was broken after installing Connector/NET 6.7.x, because the data provider was not found after uninstalling MySQL for Visual Studio. (Bug #16973456)
The LINQ query would return the error "An error of "Unknown column 'Distinct1.nCdSite' in 'where clause'" when using Distinct().Count(). (Bug #16950146, Bug #68513)
When the IIS application pool reset the worker processes at a specific time, the MySQL session state store would crash the w3wp.exe process and the request resulted in a crash error message. There are no longer ASP.NET crash yellow pages or bad exceptions. Session expiration is now handled properly. (Bug #16909237, Bug #67665)
When using automatic migrations in Entity Framework 5.0, the database objects were given the 'dbo' prefix. This incorrect prefix is no longer generated. (Bug #16909439)
An "DBUpdateException saving changes" exception was thrown while inserting data that had Identify columns. The data is now stored in the table.
A workaround was to set global sql_mode = "ANSI";. (Bug #16494585)
Generated "LINQ to Entities" queries are no longer as nested. In other words, two similar queries with one nested inside the other are now flattened into a simple query. This provides better performance for large result sets. (Bug #65723, Bug #16973939)
An exception was thrown when populating DataTable with query fields containing a UNIQUE index or constraint NULL. There is no longer an exception thrown, and the DataTable.Fill method terminates correctly (filling the data). (Bug #65065, Bug #16952323)
Sometimes data was not returned when a socket connection was slow, interrupted, or delayed. The timeout is now properly reported as an error to the upper layers. (Bug #69039, Bug #16950212)
Using a nested projection causes a malformed query to be created, and spurious data to be returned. (Bug #67183, Bug #16872852)
