** Changes since 5.2.3 **
- fixed web providers autogenerateschema option where it would fail if no schema is

present at all (bug #39072)
- backported fix for lingering problem related to bug #37239.
If two columns had the same name but

different case then an exception would be thrown.
- fixed stored procedure parameter parsing when used inside server explorer.
(bug #39252)
- fixed time data type so that negative values are handled properly (bug
#39275)
- added runtime check for the mono platform to our Membership provider.

The mono runtime

as of 1.9.1 did not support the methods needed for hashed passwords (bug #38895)
- fixed problem where negative time values with a zero hour would return as positive

values (bug #39294)
- fixed problem where using a stored procedure with parameters with a table adapter

was no longer working after our parameter schema changes (bug #39252)
- fixed problem with profile provider where INSERT .. ON DUPLICATE UPDATE syntax would not

work correctly with some older server versions (bug #39330)
- Defaulting max allowed packet to 1024 to account for the possible case where the

value doesn't come in as a server variable
- fixed bug #39728 by making
MySqlConnectionStringBuilder.GetConnectionString an internal method.

It should not have been publicly available anyway.
It is used internally by the

MySqlConnection.ConnectionString property
- implemented Disposable pattern on MySqlTransaction class so including one in a using statement

and then not calling commit will cause a rollback when the using exits (bug #39817)
- fixed MySqlScript object so that it handles scripts with user variables
- fixed bug where specifying 'functions return string=yes' would cause strings to be returned

using the 'binary' charset which would not properly render some characters.
Now the

connection character set is used. (bug #40076)
- fixed problem that caused in use connection strings to be modified when a pooled connection

timed out and was cancelled.
(bug #40091)
- fixed problem where using respect binary flags would not use the connection char set

and therefore return strings with a bad encoding.
- fixed bug where provider was attempting to use the new parameters I_S view on servers

that didn't have it (bug #40382)
- fixed problem where CharSetMap.GetDefaultCollation and CharSetMap.GetMaxLengths

might have a thread sync issue on high load systems.
They were not locking

the static collections there were initializing. (bug #40231)
- added GetSByte to the reader for returning tinyint columns (bug #40571)
