 ### Updates
 
+* Updated to the latest build of [p2.js](https://github.com/schteppe/p2.js/commit/d1c7a340c42e4d5d1d939fba5fd13c5e49d6abd2)
 * TypeScript definition updates to help fix for the `noimplicitany` option (thanks @Waog #1088)
 * All of the Pixi geom classes have been removed from the build file as they aren't needed (the Phaser.Geom classes overwrite them), saving some space in the process.
 
+### p2.js changes
+
+* DistanceConstraint signature changed to take the new localAnchors.
+* 
+
 ### New Features
 
 * Device will now detect for Kindle and PS Vita (thanks @lucbloom)
