AMD typically release their "Optional" Drivers Adhoc (i.e. whenever they think they've fixed / improved something, they push it out) … so it's not uncommon to have an Optional Driver every 1 - 2 Weeks.
With this said they're currently committed to a "Day One" Driver Update for every major Release., so whenever a new game comes out; they'll push a new update. This will typically be either the day before... or on Release itself.
Now Adrenalin is supposed to push a Windows Notification whenever a New Optional / Recommended Driver is available... this typically doesn't happen. The Optional Drivers seem to only get a Notification if you manually "Check for New Driver" or the AMD Driver Team remember to push the notification., where-as the Recommended will typically Automatically Install.
As a note the Call of Duty Modern Warfare ("Game Ready") Driver was released a few hours ago., as Optional 19.10.2
According to the notes it improves performance (on Ultra High Settings) by about 8%... with no other known issues.
The Outer Worlds ("Game Ready") Driver is also part of this package; providing a similar performance uplift but there is a known issue with the Character Model disappearing on the Inventory Screen., this hasn't been fixed but is known (thus will probably see a fix in the coming weeks).

One thing I would recommend is getting and setting up the AMD Link App for your Android / iOS Device.
It's essentially the Radeon Overlay / Settings (Alt-R) but on your Phone, and it allows you to Real-Time interact; so you can for example Tweak GPU Settings., Monitor your Card., use ReLive., Stream to other Devices., etc.
It also does keep you notified of updates such-as New Drivers.
