and crash recovery by default.

MySQL 5.5 also provides a number of additional enhancements including:

  - Significantly improved performance on Windows, with various Windows
    specific features and improvements
  - Higher availability, with new semi-synchronous replication and
    Replication Heartbeat
  - Improved usability, with Improved index and table partitioning,
    SIGNAL/RESIGNAL support and enhanced diagnostics, including a new
    Performance Schema monitoring capability.

Changes in MySQL 5.5.58 (2017-10-16, General availability)

   Packaging Notes

     * mysqlcheck was missing in the MySQL Server Docker image,
       which prevented mysql_upgrade from running. (Bug #26400146,
       Bug #86968)

   Bugs Fixed

     * Replication: Replication clients no longer enable LOCAL
       capability for LOAD DATA statements, because they do not use LOAD
       DATA LOCAL statements. (Bug #24763131)

     * yaSSL could incorrectly perform TLS cipher negotiation.
       (Bug #26482173)

     * The server failed to check the maximum path length for
       partition names. (Bug #26390632)

     * Identifiers containing a mixture of backslashes and
       backticks could be parsed incorrectly. (Bug #26372491)

     * NAME_CONST() can return null if incorrect arguments are
       given. In some cases, this was not handled and could cause a
       server exit. (Bug #19143243, Bug #26361149)
