This is an automated email summarizing recent activity on the  
developer-signals repo, which is where web developers add their support for  
web features that are not yet implemented in all major browsers.


Federated Credential Management made a strong debut, instantly becoming the  
most active feature with 35 upvotes. Momentum from the previous period  
continued for several highly-requested features, including Anchor  
positioning which gained another 17 upvotes. A customizable <select>  
element (14 new upvotes), the Temporal API, and JPEG XL (both with 11 new  
upvotes) also maintained significant developer interest. Additionally, the  
CSS corner-shape property and container scroll-state queries saw notable  
increases in support.
