MySQL Connector/Net 8.0.8 is the fifth development release that expands cross-platform
support to Linux and macOS when using Microsoft’s .NET Core framework. Now, .NET
developers can use the X DevAPI with .NET Core and Entity Framework Core (EF Core)
1.0 to create server applications that run on Windows, Linux and macOS. We are very
excited about this change and really look forward to your feedback on it!

MySQL Connector/Net 8.0.8 is also the seventh development release of MySQL
Connector/Net to add support for the new X DevAPI. The X DevAPI 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/index.html.
For more information about how the X DevAPI is implemented in Connector/Net, see
http://dev.mysql.com/doc/dev/connector-net.

Note

The X DevAPI requires at least MySQL Server version 5.7.12 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/5.7/en/document-store.html.

Changes in MySQL Connector/Net 8.0.8 (2017-07-10, Development Milestone)

   MySQL Connectors and other MySQL client tools and
   applications now synchronize the first digit of their version
   number with the (highest) MySQL server version they support.
   For example, MySQL Connector/Net 8.0.12 would be designed to
   support all features of MySQL server version 8 (or lower).
   This change makes it easy and intuitive to decide which
   client version to use for which server version.

   MySQL Connector/Net 8.0.8 is the first release to use the new
   numbering. It is the successor to MySQL Connector/Net 7.0.7.

     * Functionality Added or Changed

     * Bugs Fixed

   Functionality Added or Changed

     * X DevAPI: The format of document ID values generated when
       adding documents to a collection has changed. It is still
       a string of 32 hexadecimal digits based on UUID, but the
       order of digits was changed to match the requirement of a
       stable ID prefix.

     * All connections created using MySQL Connector/Net now are
       secure by default. Also, the Ssl-Enable connection option
       has been replaced by Ssl-Mode. Permitted Ssl-Mode values
       are None, Required (the default), VerifyCA, and
       VerifyFull.

       With this change, a non-SSL enabled server now requires
       the Ssl-Mode option be set to None explicitly in the
       connection string or the connection will fail.

     * X DevAPI: It is no longer permitted to pass an empty
       search condition, such as the NULL value or an empty
       string, to the Collection.Modify and Collection.Remove
       methods.
	
     * X DevAPI: The NodeSession class has been renamed to
       Session and the MySQLX.GetNodeSession method has been
       renamed to MySQLX.GetSession. Also, the XSession class
       has been removed.

     * X DevAPI: When creating a new connection, multiple hosts
       now can be specified as part of the connection string,
       which will try each host until a successful connection is
       established or all elements from the host list have been
       tried. The following connection-string formats are
       supported:

	    var mySession = MySQLX.GetSession(
	      "mysqlx://dbuser:password@[" +
	      "localhost:33060," +
	      "192.1.10.10:33060," +
	      "[2001:db8:85a3:8d3:1319:8a2e:370:7348]:33060" +
	      "]"
	    );

	    var mySession = MySQLX.GetSession(
	      "user=dbuser;" +
	      "password=dbpassword;" +
	      "server=" +
	      "192.1.10.10," +
	      "server.example.com," +
	      "localhost;" +
	      "port=33060;"
	    );

   Bugs Fixed

     * EF Core: The Database First feature did not support the
       following data types: BINARY, VARBINARY, MEDIUMBLOB,
       LONGBLOB, SET, DATE, TIME, and YEAR. (Bug #25493209)

     * EF Core: Database First support produced an error when
       the existing MySQL database included one or more views.
       (Bug #25493086)

     * EF Core: Using
       System.ComponentModel.DataAnnotations.Schema.TableAttribu
       te to initialize a new class instance that specified the
       name of an existing MySQL table produced incorrect
       mappings of table and column names.
       (Bug #25394223, Bug #84423)
