March 2026 saw several web platform features reach Baseline interoperability milestones. Newly available features include the math font-family for MathML, Iterator.concat() for combining iterables, readable byte streams for efficient binary data handling, the Reporting API for browser-level error notifications, WebTransport for low-latency HTTP/3 communication, and new text-indent keywords (each-line and hanging). A large set of features also reached the Widely available tier (30 months of interoperability), including CSS subgrid, contain-intrinsic-size, @counter-style, image-set(), link rel=modulepreload, hyphens properties, overflow media queries, navigator.storage, and device orientation events.
