I went through and archived a bunch of the older Release Notes announcements since the category was starting to get a bit cluttered. These are still available to view by clicking "Archived Topics" at the top.

Good idea! But I don't see any archived topics button, maybe only administrators can see it? I was thinking about making a kind of cheat sheet based on the various announcements, since there are some cool features like translation, expression tokens, developer console or arithmetic expressions that I keep forgetting how to use exactly.

You are correct - after looking more closely, I see that the button to view archived topics is listed as a moderator action.

I am going to unarchive them for now. :) Maybe I could do something similar to your idea at some point and make a sticky post containing a summary of new features/changes that have been done during Founder's Access.

I had a look at the development updates and various other posts, here's what I came up with: https://wri.tt/o987dkqouum5tndz

Nice, thanks for putting this together! If you don't mind, I may post this as a sticky topic somewhere like Help & Support since it would be a useful reference.

Sure, feel free to do that :) I'll update it when needed.
