Functionality Added or Changed

• Important Change: For platforms on which OpenSSL libraries are bundled, the linked OpenSSL library for MySQL Cluster Manager has been updated to version 3.0.16. Issues fixed in OpenSSL version 3.0.16 are described at https://openssl-library.org/news/openssl-3.0-notes/. (Bug #37656086)

• Agent: MySQL Cluster Manager now uses the third-party library GLib version 2.82.4. The new GLib version is included in the MySQL Cluster Manager distribution archive. (Bug #37475574)

• A new client command, list certs, lists the files created by the create certs command for a cluster. (Bug #36698435)

Bugs Fixed

• Agent: The stop process timed out for processes in the ADDED state. (Bug #37691818)

• Agent: The create certs command failed after an mcmd agent queried another agent for the certificate authority and key, which were not created by that agent. With this fix, the agent moves on to query another agent in that situation. (Bug #37639369)

• Agent: The backup cluster command failed with an "Access denied" error when the mcmd_password had a '#' at the end. (Bug #37609816)

• Client: A delete cluster command failed if the backup's schema file containing the metadata of the NDB tables was missing (for example, due to accidental manual deletion). With this fix, the command works in such situations. (Bug #37660069)

• Client: At the debug log level, the mcmd log prints the wrong comments for some of the planned steps for the create certs --renew --certs command. (Bug #37464246)
