Today's release included a change to the way that discussions can be viewed by users. There is a new button on the upper righthand corner of the discussion (see attached screengrab). When clicked, it will allow you to see the most recent "parent" post. That is, it sorts all of the non nested replies in reverse chronological order. Clicking that button holds your preference around the site, so just click it again if you want to look at discussions the "old" way, in chronological order.
In addition, there was a release to allow for continuous loading on user's profile pages on mobile, in addition to the category pages. So you can now browse back as far as you'd like with ease!
We hope that these improvements help your Chowhound experience. Thanks,
