Previously, it was not possible to install both the 32-bit and 64-bit variants of Connector/ODBC. It is now possible to install both, if required, and to upgrade older versions of Connector/ODBC 8.0 to version 8.0.33 (and later). (Bug #35078964)

When MySQL Installer runs on a host with no internet connection, it can appear to be unresponsive for several minutes while it searches for a connection. With this fix, the wait time is reduced. In addition, if MySQL Installer detects no connection at startup, it provides a new prompt to run in offline mode, which resumes user interaction immediately without internet capabilities. Offline mode can be enabled or disabled independently with an option located in the General tab of the MySQL Installer Options dialog or from the command line using the --set --offline-mode command.

MySQL Installer now checks for the SHA256 digests of ZIP and MSI files to ensure that the downloaded packages are valid. (Bug #16656800)

Semicolons are now supported as part of a root password. All characters that MySQL Server supports by default are also supported by MySQL Installer. (Bug #77840, Bug #21507764)

In some cases, the server configuration operation was unable to switch between strong and legacy authentication methods, causing the configuration to stop without recourse. (Bug #34947724)

MySQL Installer could create instances of WebClient, CookieAwareWebClient, or both when performing each web request. In some cases, it did not dispose of these resources properly. This fix now permits reusing the same object, if possible, to improve performance and reliability. (Bug #34811548)

Too many concurrent products could cause disruptive errors during a web-package download operation. MySQL Installer now automatically detects failed downloads caused by an excess of concurrent products and trims the number permitted to reduce the likelihood of errors. It also retries a failed product download up to three times. (Bug #34811533)

Product version conflicts could occur between products installed using MySQL Installer and products installed using standalone product MSI files. Now, MySQL Installer sets the correct configuration consistently and permits upgrades between products with different configurations. (Bug #28226183)
