The clearest thread today is cleanup following James Snell's DTLS improvements in PR 64314. That change introduced destructured test helpers that violated lint rules and, in two files, called assertion functions that were never even imported — a bug that would throw at runtime. Matteo Collina caught and fixed both…
Second theme: streaming performance is getting sustained attention. Collina landed PR 64818, moving the byte stream controller's pending BYOB descriptor list onto the same ring-buffer structure already used elsewhere in WHATWG streams, cutting per-read allocation costs. He's also got PR 64890 open, targeting…
Third: a security-and-safety theme in native bindings. PR 64881 fixes a crash in FFI's ref and unref callback handlers that could dereference an empty handle after garbage collection — now throws a proper argument error instead. PR 64878 does the same for DNS's `lookupService`, replacing a native assertion crash…
