Changes in MySQL Installer 1.6.16 (2025-08-18)

• Functionality Added or Changed

• Bugs Fixed

Functionality Added or Changed

• When using MySQL Installer to create and configure an InnoDB cluster and bootstrap MySQL Router, the default user in the MySQL Router configuration is now root and the default port is now 3310. (Bug #30048667)

Bugs Fixed

• The Next button was not enabled by default on the Select Product To Upgrade page, when all products were selected for upgrade. (Bug #38268979)

• When run in silent mode, the MySQL Community Server Installer installed the commercial instead of the community version of MySQL. (Bug #38070201)

• After a product was downloaded by the Download step of MySQL Installer, navigating back to the Select Products page and clicking Next would display the Download page again, even when there was nothing left to download; this fix prevents the Download page from appearing unnecessarily in that scenario. (Bug #32177323)

• When installing the Samples and Examples, the installer did not check there was a valid version of the server present and displayed the Samples and Examples configuration page.

  As of this release, the configuration page is only displayed if a valid version of the server is present. Similarly for the Reconfigure link for MySQL Router. (Bug #30179541)

• One or more of the following issues occurred when the Cancel button was clicked as MySQL Installer was in the process of executing installations or updates for MySQL products, depending on the situation:

  • MySQL Installer quits unexpectedly.

  • The confirmation dialogue for the cancellation came up twice.

  • For products whose installations or updates were cancelled, new attempts to install or update them failed, unless MySQL Installer is restarted.

  With the fixes, the cancellations work as expected. Notice that you cannot cancel an installation or update that is already underway; you can only cancel the installations or updates that have been selected and are waiting for execution. And for that reason, if there is only one product to be installed or updated and its execution has started, the Cancel button is now disabled. (Bug #29331115, Bug #30765522)

• When users specified an out-of-range MySQL Router port number, the error message gave the wrong range. The error message was also repeated unnecessarily at a few other steps. (Bug #28543086)
