Inspector probe mode gains per-probe conditions (
8c6cbb8)
node inspect now accepts --cond <expr> alongside each probe/expression pair, letting you suppress hits unless the condition is truthy at the probe location. That makes probe mode much more usable on hot paths, and the new rules clarify how conditions interact when multiple probes share the same location.
EventEmitter stops retaining removed event names (
35115c0)
Removed listener names are no longer kept around as forever-undefined properties on ordinary emitters, avoiding unbounded growth when event names are unstructured. Preallocated emitters still preserve shape mode, so this keeps the performance win without the memory leak.
WHATWG stream request queues switch to a ring buffer (ace91de)
Readable and writable stream request queues now use the shared Queue structure instead of plain arrays with repeated shift() calls. This removes O(n) queue draining behavior and cuts overhead in common stream reader/writer paths.
EventEmitter once/removeListener get faster (384d7a4)
once() now uses a closure instead of a bound state object, and listener removal keeps object shape stable while also outlining a few cold paths for V8 inlining. The change is a broad performance refactor for one of Node's most frequently used subsystems.
