V8 CPU profiling now accepts options (
4e332e0)
v8.startCpuProfile() and worker.startCpuProfile() now take an options object with sampleInterval and maxBufferSize. The implementation wires those settings through the V8 and worker internals, giving users control over profile granularity and retained sample count.
HTTP keep-alive default increased to 65 seconds (
9f75269)
Node’s default http.Server.keepAliveTimeout has been raised from 5s to 65s. That changes connection reuse behavior for servers by default, and the docs/tests were updated to reflect the new timeout.
URLSearchParams set/delete duplicate handling optimized (
c202696)
URLSearchParams.set() and .delete() were rewritten to avoid repeated splice() calls while mutating the internal list. This should reduce overhead on large parameter sets, and the new benchmark covers unique vs. duplicate-heavy cases.
processTicksAndRejections() skips unnecessary rejection work (44f9fc3)
Promise rejection processing now only runs when there is actually rejection work pending. This trims extra work from the tick/rejection loop without changing the observable API.
