The headline today is convergence on promise-based patterns and cleanup of edge-case correctness across core APIs. The biggest addition is PR 63965 from Ethan Arrowood: an experimental net slash promises namespace, giving connect and listen operations the same async, await-friendly treatment already available in fs…
On the reliability side, bitpshr's fix in PR 64481 closes a real memory leak in AbortSignal dot any. Composite signals that observed a long-lived source were never being removed from the internal retainer set once aborted, so they'd accumulate indefinitely even after garbage collection. If you're building…
A second theme is standards compliance and validation hygiene. HoonDongKang's PR 64739 aligns Blob's slice method with the File API's Web IDL spec, fixing how fractional start and end values are handled — this had been failing web platform tests. Soulee-dev's PR 64731 swaps a hand-rolled boolean check in async hooks…
Smaller but worth noting: luanmuniz's PR 64146 fixes broken argument parsing in the benchmark calibration tool, where threshold values were silently becoming NaN. And test-focused work continues,…
