List of Duolingo's past improvements
Duolingo always seems to be improving, which is terrific, e.g., today I'm seeing "concepts" come up in the exercises.
Is there a chronological list of recent changes somewhere on the site? Sort of like a news feed from staff?
Thanks for reading.
Luis usually posts the announcements about new features in Discussions. Apart from that, some new features are blind-tested, i.e. introduced to some people without any announcement to test their effectiveness without bias.
What kind of "concepts" do you mean?
I think what you're looking for is a changelog. I agree that it would be neat to have a changelog just to look at, though realistically it's super low on my list of things I would like the staff to concentrate manpower on :)
