The best way to know what is happening is to use RSS. And there is a couple of nice rss that you can use to stay updated.
First there is the news about this and that, that I post on this page.
Then we have the FunTechCortexMX project that will build the toolchain, the the test suite to verify it.
And the template project that will become a reference project, and show how you can use this toolchain in a nice way.
