This site automatically collects, indexes, and makes available for viewing (and as subscribe-able feeds), information about updates to Browser Compatibility Data (BCD). Currently there are two different views (and feeds) on this data, which are compiled each Tuesday (US/Eastern time). h/t https://researchbuzz.masto.host/@researchbuzz/113210277764638289 Perhaps you're interested in which changes were reported last week, or more specifically which features became "new baseline" last week (marked as available in all 3 engines).
