Connector/Net 5.0.5 has been released.

MySQL Connector/Net 5.0.5 a new version of the all-managed .NET driver for MySQL has been released.

This is a bug fix release for the current production branch of Connector/Net.
Version 5.0.5 is suitable for use with any MySQL version including MySQL-4.1, MySQL-5.0, MySQL-5.1 beta or the MySQL-5.2 Falcon "Preview".

It is now available in source and binary form from the Connector/Net download pages at http://dev.mysql.com/downloads/connector/net/5.0.html and mirror sites (note that not all mirror sites may be up to date at this point of time - if you can't find this version on some mirror, please try again later or choose another download site.)

What happened to 5.0.4?
We had 5.0.4 packaged up and ready to go and then discovered that a previous bug fix was not complete.  Rather than release 5.0.4 and then follow that up with a quick release of 5.0.5, we decided to not release 5.0.4 at all.  This allowed us to roll in a couple of additional last minute bug fixes.

Functionality Changes or Enhancements
* Return parameters created with DeriveParameters now have the name
  RETURN_VALUE
* Fixed problem with parameter name hashing where the hashes were not
  getting updated when parameters were removed from the collection.
* Fixed problem with calling stored functions when a return parameter
  was not given
* Fixed problem that prevented use of SchemaOnly or SingleRow command
  behaviors with sprocs or prepared statements
* Assembly now properly appears in the Visual Studio 2005 Add/Remove
  Reference dialog
* Added MySqlParameterCollection.AddWithValue and marked the Add(name,
  value) method as obsolete
* Added "Use Procedure Bodies" connection string option to allow calling
  procedures without using procedure metadata. (see release notes)
* Reverted behavior that required parameter names to start with the
  parameter marker.  We apologize for this back and forth but we
  mistakenly changed the behavior to not match what SqlClient supports.
  We now support using either syntax for adding parameters however we
  also respond exactly like SqlClient in that if you ask for the
  index of a parameter using a syntax different than you added the
  parameter, the result will be -1.
