When does Grafana images get the latest Plugin versions?

I am interested in the latest Canvas features, but when I run the latest version as a container, the Canvas version is from the 10th of April (more than 6 months old). How often the built-in plugins get updated? I can’t find a way to manually update it.

Edit: In the Canvas page, the latest update is also from the 10th of April Canvas plugin for Grafana | Grafana Labs
In Play Grafana, the newest features are available.

Apparently, the features were released in 12.2. No idea why the Canvas version is still written as “10th of April”.
