February 2021 Update Notes?

Is there somewhere we can see notes about what exactly is being updated each time? I am updating Fresco and everything else because an update became available, but I would like to see what problems are being fixed specifically in the update. 

Fresco has been incredibly buggy for me the last month or so and I am crossing my fingers hard about this update. Would love to hear about whether it improves stability or experience for people...

Mostly, I want to be able to just work in the app for extended periods without sudden onsets of lag or unexpected crashing, also maybe an eye dropper that doesn't take an extra second to register my selection.

I love this app when it works. Really love it. I just need it to be stable and consistent for hours and hours at a time.
