Dear MySQL users, 

MySQL Connector/Node.js is a new Node.js driver for use with the X 
DevAPI. This release, v8.0.24, is a maintenance release of the 
MySQL Connector/Node.js 8.0 series. 

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. 

MySQL Connector/Node.js can be downloaded through npm (see 
  https://www.npmjs.com/package/@mysql/xdevapi for details) or from 
  https://dev.mysql.com/downloads/connector/nodejs/. 

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 MySQL 
Connector/Node.js, and its usage, see 
  http://dev.mysql.com/doc/dev/connector-nodejs/. 

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. 

Changes in MySQL Connector/Node.js 8.0.24 (2021-04-20, General Availability)

     * Functionality Added or Changed

     * Bugs Fixed

Functionality Added or Changed

     * Important Change: Starting in this version,
       Connector/Node.js will ignore compatibility with
       End-of-life Node.js versions. If you are planning to
       upgrade, make sure you are using Node.js 12.0.0 or
       higher.

     * Connector/Node.js no longer guarantees compatibility with
       End-of-life Node.js versions. Today this means only
       Node.js 12.0.0 or higher are officially supported.

     * Improved the inline documentation and added functionality
       for users to generate it locally using JSDoc. See
       CONTRIBUTING.md for instructions on how to generate the
       HTML documentation.

     * Improved server disconnection handling of X Protocol
       connections now creates a log entry and returns an error
       message, as needed, after Connector/Node.js receives a
       connection-close notice from the server.
       Connector/Node.js detects three new types of warning
       notices.

          + Connection idle notice: This notice applies to a
            server connection that remains idle for longer than
            the relevant timeout setting. Connector/Node.js
            closes the connection when it receives the notice in
            an active session or while a new session is being
            created. An attempt to use the invalid session
            returns the "Connection closed. Reason: connection
            idle too long" error message.

          + Server shutdown notice: If a connection-close notice
            is received in a session as a result of a server
            shutdown, Connector/Node.js terminates the session
            with the "Connection closed. Reason: server
            shutdown" error message. All other sessions that are
            connected to the same endpoint are removed from the
            pool, if connection pooling is used.

          + Connection killed notice: If the connection being
            killed from another client session,
            Connector/Node.js closes the connection when it
            receives the notice in an active session or while a
            new session is being created. An attempt to use the
            invalid session returns the "Connection closed.
            Reason: connection killed by a different session"
            error message.

Bugs Fixed

     * The getSession() method now executes release() if a
       getSession() exception is raised; as ot was not releasing
       the connection to the pool. (Bug #32366743, Bug #101928)

     * The Session.getDefaultSchema() method now returned
       'undefined' instead of a valid Schema instance if a
       default schema is not set. (Bug #32136490)

                 
On Behalf of the MySQL Engineering Team,
