New

Ads & Trackers (Beta): blocks trackers and ad networks, plus YouTube and Facebook ads, “turn off your ad blocker” walls, and the empty boxes ads leave behind. Off until you switch it on.
Catches shop tricks: Sieve remembers what a shop told you last time, so a fake countdown, an “only 2 left” that never changes, or a sale that “ends today” every day gets caught.
“On this page”: the toolbar popup lists the tricks found on the page you’re on, with Show me and Undo for each.
Free-trial warnings: shows the real price and the date you’ll be charged, in any currency, and can remind you two days before.
Fake popularity: hides “Sarah just bought this” pop-ups and flags “23 people are viewing this” counts that nobody can check.
AI Blocker: three optional switches, for AI chatbots, AI writing tools and AI companions.
Cool-off: an optional wait (1 hour to 7 days) before you can turn your protection down.
More YouTube switches: hide search suggestions, the sign-in prompt, “More from YouTube” and the sidebar feed.

Changed

A new look, a new sieve icon, and a Light/Dark/System appearance setting.
Lighter and faster on every page, with a smaller download.

Fixed

Turning off autoplay and hiding end cards on YouTube now actually work.
The Popup Blocker now works on most sites, and a site can no longer switch it off for itself.
The Dark Pattern Blocker no longer mislabels innocent buttons and checkboxes.
