We removed the "Was this helpful" question because it... wasn't helpful. You'll be able to provide us with feedback in a different way in an upcoming release.
We fixed an accessibility issue where the label for certain notes and examples wasn't announced when using a screen reader.
On articles with accordions, we fixed an issue where the accordions would jump around when selected. Accordions can help simplify the page, lowering users' cognitive load and allowing them to concentrate on the information immediately at hand.
We fixed an issue where the page broke if the video player was re-sized to be full screen.
