Dear MySQL users,

MySQL Server 5.6.50, a new version of the popular Open Source
Database Management System, has been released. MySQL 5.6.50 is
recommended for use on production systems.

For an overview of what's new in MySQL 5.6, please see

     Starting with 5.6.11, Microsoft Windows packages for MySQL 5.6
     are available both as a "full" installer and as a "web" installer.
     The full installer is significantly larger and comes bundled with
     the latest software releases available. This bundle makes it easy
     to download and configure a full server and development suite.

     The web installer doesn't come bundled with any actual products
     and instead relies on download-on-demand to fetch only the
     products you choose to install. This makes the initial download
     much smaller but increases install time as the individual products
     will need to be downloaded.

For information on installing MySQL 5.6.50 on new servers or upgrading
to MySQL 5.6.50 from previous MySQL releases, please see

MySQL Server 5.6.50, is available in source and binary form for a number of
platforms from our download pages at

We welcome and appreciate your feedback, bug reports, bug fixes,
patches, etc:

Changes in MySQL 5.6.50 (2020-10-19, General Availability)

Functionality Added or Changed

     * LOCK TABLES privilege checking for views was improved.
       (Bug #31304432)

Bugs Fixed

     * InnoDB: In session started with START TRANSACTION WITH
       CONSISTENT SNAPSHOT, a range query returned a truncated
       result. The end range flag was not reset at the beginning
       of the index read resulting in an aborted read and
       missing rows. (Bug #30950714, Bug #98642)
       References: This issue is a regression of: Bug #23481444.

     * In bootstrapping mode, certain multiple-statement
       transactions could cause unexpected server behavior. (Bug

     * Assigning CONCAT('') or CONCAT_WS('') to a variable set
       the variable to NULL, not the empty string. (Bug
       #31320716, Bug #99485, Bug #31413167, Bug #99722)

     * ORDER BY queries were not executed correctly when
       sort_buffer_length and max_sort_length were set to values
       which caused the internal limit on the maximum number of
       keys allowed per sort buffer to be set to 0. (Bug

     * The internal method Field_tiny::pack() did not always
       perform bounds checking as expected. (Bug #29948029)
       References: See also: Bug #31591391.

     * A large number of nested arguments in full-text search
       query caused an error. (Bug #29929684)

     * An assertion could be raised when the SQL layer passed
       incorrect information to InnoDB about the type of
       operation to be performed on a temporary table. (Bug
