New this build: improvements to Crosswalk, including support for detecting system buttons like the back and menu buttons. There's also a few other bug fixes and tweaks. Intel are going to keep improving Crosswalk on their end, so hopefully some new features and improvements will keep coming from them too. In case you missed it, you can find out more about our new support for Android via Crosswalk in the blog post Introducing Crosswalk: the new way to publish to Android.
Please also note the breaking change regarding the Sprite 'AnimationSpeed' expression. Some projects may rely on the fact this returned a positive value even when the animation was playing backwards; it now returns a negative value in this case. This is probably unlikely to affect many projects, but it is something that works differently so could potentially break things that depend on how it used to work.
This build is a little late since we took some time off over the holidays, but we should be back to our regular cycle now. Hopefully we'll have a stable update out soon as well.
