It's actually been here for as long as I've been a member. With the new format you go to the top and click on the three dots to the right of your avatar to get to it.If you click in the search box it shows a second box called "Advanced Search". Click on Advanced Search and you can select just the forums you want to search and filter like old times.
They are working on that. Click the 3-dot menu, then FAQ, then on the left menu RELEASE NOTES. I haven't yet found a way to actually subscribe to updates to the RELEASE NOTES section, but they DO include a pop-up notification when changes occur. We will see if allowing PUSH NOTIFICATIONS advises us of site changes after releases.It's kind of a challenge to find the features with the new format.
Sneaky buggers. That's precisely the functionality that wasn't there last week. Shoulda renamed it "advanced advanced search".Look at the upgraded ADVANCED SEARCH again
