Now that Ops Center 12.3.1 is released, you may be interested in upgrading.
The process is fairly simple - similar to past upgrades - with one important addition. If you're using an embedded database, we've upgraded the version to 184.108.40.206. If you have an embedded database, you'll need to download the installation bundles for 220.127.116.11 before performing the upgrade. If you're using a customer-managed database, you can upgrade your database to 18.104.22.168 at any point after upgrading Ops Center to 12.3.1.
The Upgrade Guide goes into detail about how to upgrade your environment, with separate procedures based on your environment (single EC or HA) and your preferred method of upgrading (UI or command line).
