@benorfaz should this be a non-dimissible notice, or should we allow customers to dismiss it?

What about potential hotfix releases, 3.16.0.1, etc?

from wp-rocket.

Could you provide the IDs for the docs, and same for the FR versions?

Also, I'm not sure how we can handle the old version check, because we're not in the update process, so that value is no longer available, as we don't store it.

Same for the fresh install, we don't have an indication that the current installation is new.
