+* **combineLatest:** emit unique array instances with the default projection ([2e30fd1](https://github.com/ReactiveX/RxJS/commit/2e30fd1))
+* **Observable.from:** standardise arguments (remove map/context) ([aa30af2](https://github.com/ReactiveX/RxJS/commit/aa30af2))
+* **schedulers:** fix asap and animationFrame schedulers to execute across async boundaries. (#182 ([548ec2a](https://github.com/ReactiveX/RxJS/commit/548ec2a)), closes [(#1820](https://github.com/(/issues/1820) [#1814](https://github.com/ReactiveX/RxJS/issues/1814)

+### BREAKING CHANGES
+
+* Observable.from: - Observable.from no longer supports the optional map function and associated context argument.
