• #12471 Fixed an issue that data integration configurations failed to load correctly during upgrades from EMQX version 5.0.2 to newer releases.

  • /clients/:clientid/subscribe/bulk

  • /clients/:clientid/unsubscribe

  • /clients/:clientid/unsubscribe/bulk

• #12601 Fixed an issue where logs of the LDAP driver were not being captured. Now, all logs are recorded at the info level.

• #12606 The Prometheus API experienced crashes when the specified SSL certificate file did not exist in the given path. Now, when an SSL certificate file is missing, the emqx_cert_expiry_at metric will report a value of 0, indicating the non-existence of the certificate.

• #12620 Redacted sensitive information in HTTP headers to exclude authentication and authorization credentials from debug level logs in the HTTP Server connector, mitigating potential security risks.
