The configuration templates provided by MySQL Installer now omit the
query_cache_size
andquery_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.
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server system variable, which is no longer valid.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 replacestable_cache
with thetable_open_cache
variable in the configuration files of these servers. (Bug #14700224, Bug #67053)
