Dear MySQL users,
MySQL Connector/NET 8.0.23 is the latest General Availability release
of the MySQL Connector/NET 8.0 series. This version supports .NET 5.0
and the X DevAPI, which enables application developers to write code
that combines the strengths of the relational and document models
using a modern, NoSQL-like syntax that does not assume previous
experience writing traditional SQL.
To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/
For more information about how the X DevAPI is implemented in
Connector/NET, see
http://dev.mysql.com/doc/dev/connector-net
NuGet packages provide functionality at a project level. To get the
full set of features available in Connector/NET such as availability
in the GAC, integration with Visual Studio’s Entity Framework Designer
and integration with MySQL for Visual Studio, installation through the
MySQL Installer or the stand-alone MSI is required.
Please note that the X DevAPI requires at least MySQL Server version
8.0 or higher with the X Plugin enabled. For general documentation
about how to get started using MySQL as a document store, see
http://dev.mysql.com/doc/refman/8.0/en/document-store.html
To download MySQL Connector/NET 8.0.23, see
http://dev.mysql.com/downloads/connector/net/

Enjoy!
Changes in MySQL Connector/NET 8.0.23 (2021-01-18, General
Availability)
Functionality Added or Changed
* Connector/NET updates to SSH ciphers and algorithms are:
+ Encryptions: aes192-cbc, aes256-cbc (deprecated);
3des-cbc, blowfish-cbc, twofish-cbc, twofish128-cbc,
twofish192-cbc, twofish256-cbc (invalid)
+ Host Key Algorithms: ssh-rsa (deprecated); sh-dss
(invalid)
+ Key Exchange Algorithms:
diffie-hellman-group-exchange-sha1 (invalid)
+ Keyed Hash Message Authentication Codes:
hmac-ripemd160,hmac-ripemd160@openssh.com,
hmac-sha1-96 (invalid)
For a complete list, see SSH Ciphers in Connector/NET
https://dev.mysql.com/doc/connector-net/en/connector-net-ssh-ciphers.html
(Bug #31917057)
* The IgnorePrepare connection-string option is deprecated
in this release and the default value, which was true, is
now false. When set to true, the option instructs
Connector/NET to ignore any calls to
MySqlCommand.Prepare() made with the classic MySQL
protocol. The option is scheduled for removal in the next
release. (Bug #31872906)
* ASP.NET applications using the MySQL provider model
(MySql.Web) can now target .NET Framework 4.8.
(Bug #31799902)
* The following synonyms for the Server connection string
option were deprecated in Connector/NET 8.0.22 and
removed in 8.0.23: address, addr, and network address.
(Bug #31248601)
* Previously, Connector/NET added client support for the
MySQL Enterprise Edition SASL LDAP authentication plugin
with SCRAM-SHA-1 as an authentication method.
Connector/NET now also supports SCRAM-SHA-256 as an
alternative authentication method for classic MySQL
protocol connections. SCRAM-SHA-256 is similar to
SCRAM-SHA-1 but is more secure. SASL-based LDAP
authentication does not apply to clients running macOS.
* With the availability of Entity Framework Core 5.0 in
addition to Entity Framework Core 3.1, Connector/NET now
provides two distinct EF Core packages. The split enables
the connector to support both feature sets as they
diverge. Initially, Connector/NET supports a partial EF
Core 5.0 feature set (equivalent to EF Core 3.1) in this
release. For more information, see Entity Framework Core
Support
https://dev.mysql.com/doc/connector-net/en/connector-net-entityframework-core.html
Breaking change: all MySql.Data.EntityFrameworkCore.xxx
namespaces are renamed to MySql.EntityFrameworkCore.xxx.
New EF Core package naming for Connector/NET 8.0.23:
+ 5.0.0-m8.0.23
+ 3.1.10-m8.0.23
Bugs Fixed
* If a prepared statement had no parameters, Connector/NET
included in the COM_STMT_EXECUTE packet structure a byte
corresponding to new-params-bound-flag instead of sending
the byte only when the number of parameters was greater
than zero. (Bug #32208427)
* Incomplete validation limited the expected range of
values that a stored procedure with a parameter of type
Boolean could assign using the MySqlParameter.MySqlDbType
property. (Bug #32066024, Bug #101302)
* Stronger validation was applied to information contained
in the certificate store for connections made using
SslMode. (Bug #31954655)
* A connection timeout was added to prevent the
MySqlConnection.Open method from waiting indefinitely for
a response after MySQL Router restarted unexpectedly.
(Bug #31945397, Bug #100692)
* A cast made with the wrong data type during a valid EF
Core operation returned an exception.
(Bug #31860492, Bug #100773)
* Connector/NET used the value of -1 internally to ensure
that a parameter without an index was added to the end of
the parameter list. However, if an index with an actual
value of -1 was passed in, the collection was interpreted
as having no index and the argument did not generate an
out-of-range exception. (Bug #31754599, Bug #100522)
* Without validation, an underlying 64-bit enumeration
value passed in as a MySQL command parameter defaulted to
type Int32 and produced an overflow exception.
(Bug #25467610, Bug #84701)
Enjoy and thanks for the support!
