+- Fix: image with broken element throwing error on toObject() [#2878](https://github.com/kangax/fabric.js/pull/2878)
+- Fix: Warning on trying to set proprietary browser version of ctxImageSmoothingEnabled [#2880](https://github.com/kangax/fabric.js/pull/2880)
+- Fix: Fixed Svg import regression on color and drawing polylines [#2887](https://github.com/kangax/fabric.js/pull/2887)
+- Fix: Fixed animation ease that starts and stop at same value [#2888](https://github.com/kangax/fabric.js/pull/2888)
+- Fix: Allow a not stateful canvas to fire object:modified at end of transform. [#2890](https://github.com/kangax/fabric.js/pull/2890)
+- Fix: Made event handler removal safer. Removing firing events will not cause errors. [#2883](https://github.com/kangax/fabric.js/pull/2883)
+- Fix: Proper handling of perPixelTargetFind and multi selections [#2894](https://github.com/kangax/fabric.js/pull/2894)
+- Fix: Do not clear contextTop on drawingMode, to allow drawing over animations [#2895](https://github.com/kangax/fabric.js/pull/2895)
+- Change the dependencies to optional. Allow npm to continue installing if nodecanvas installation fail.[#2901](https://github.com/kangax/fabric.js/pull/2901)
+- Fix: Check again the target on mouseup [#2902](https://github.com/kangax/fabric.js/pull/2902)
+- Fix: On perPixelTargetFind detect corners only if target is active [#2903](https://github.com/kangax/fabric.js/pull/2903)
+- Improvement: Add canvas mouseout event listener [#2907](https://github.com/kangax/fabric.js/pull/2907)
+- Improvement: Make small object draggable easier [#2907](https://github.com/kangax/fabric.js/pull/2907)
+- Improvement: Use sendToBack, bringToFront, bringForward, sendBackwards for multiple selections [#2908](https://github.com/kangax/fabric.js/pull/2908)
