+### Notable changes
+
+* **contextify**: Fixed a memory consumption issue related to heavy use of `vm.createContext` and `vm.runInNewContext`. (Ali Ijaz Sheikh)
+https://github.com/nodejs/node/pull/5392
+* **governance**: The following members have been added as collaborators:
+ - Andreas Madsen (@AndreasMadsen)
+ - Benjamin Gruenbaum (@benjamingr)
+ - Claudio Rodriguez (@claudiorodriguez)
+ - Glen Keane (@thekemkid)
+ - Jeremy Whitlock (@whitlockjc)
+ - Matt Loring (@matthewloring)
+ - Phillip Johnsen (@phillipj)
+* **lib**: copy arguments object instead of leaking it (Nathan Woltman)
+https://github.com/nodejs/node/pull/4361
+* **src**: allow both -i and -e flags to be used at the same time (Rich Trott)
+https://github.com/nodejs/node/pull/5655
+* **timers**: Internal Node.js timeouts now use the same logic path as those created with `setTimeout()` (Jeremiah Senkpiel) [#4007](https://github.com/nodejs/node/pull/4007)
+  * This may cause a slightly different performance profile in some situations. So far, it has shown to be positive in most cases.
+* **v8**: backport fb4ccae from v8 upstream (Vladimir Krivosheev) #4231
+  -  breakout events from v8 to offer better support for external debuggers
+* **zlib**: add support for concatenated members (Kári Tristan Helgason)
+https://github.com/nodejs/node/pull/5120
+  * Previously, if multiple members were in the same archive, only the first would be read. The others are no longer thrown away.
