MySQL Installer Release Notes  /  Changes in MySQL Installer 1.4.20 (2017-08-18)

Changes in MySQL Installer 1.4.20 (2017-08-18)

Functionality Added or Changed

  • The configuration templates provided by MySQL Installer now omit the query_cache_size and query_cache_type server system variables from MySQL 5.7 and MySQL 8.0 server option files on Windows hosts. Both variables have been either deprecated or removed.

Bugs Fixed

  • MySQL Installer attempted to install the Connector/Python (x64) instead of Connector/Python (x32), based on the operating system (win64) and not on the version of Python installed. (Bug #26613477)

  • When installing Connector/Python, the prerequisite-detection mechanism failed to detect that the correct version of Python was installed on the host and the installation failed. (Bug #26578629)

  • When installing MySQL Server for Windows (32-bit) on a host with an existing instance of MySQL Server (64-bit) installed, the prerequisite-detection mechanism did not detected the required Microsoft Visual C++ redistributable package if it was missing. (Bug #25865192)

  • MySQL 5.1 and MySQL 5.5 server configuration templates continued to include the table_cache server system variable, which is no longer valid. This fix replaces table_cache with the table_open_cache variable in the configuration files of these servers. (Bug #14700224, Bug #67053)
