- Update to 2.12.5
Version 2.12.5 fixes two security vulnerabilities that may lead
to privilege escalation for authenticated API users.
Other improvements include several bugfixes related to downtimes,
downtime notifications, and more reliable connection handling.
* Security
- Don't expose the PKI ticket salt via the API. This may lead
to privilege escalation for authenticated API users by them
being able to request certificates for other identities
(CVE-2021-32739)
- Don't expose IdoMysqlConnection, IdoPgsqlConnection, and
ElasticsearchWriter passwords via the API
(CVE-2021-32743)
- Windows: Update bundled OpenSSL to version 1.1.1k #8888
Depending on your setup, manual intervention beyond installing
the new versions may be required, so please read the more
detailed information in the release blog post carefully.

- Don't send downtime end notification if downtime hasn't
started #8878

- Trigger fixed downtimes immediately if the current time
