In case you missed it, we just released the fourth milestone of Ceylon and Ceylon IDE. The next release will be the feature-complete Ceylon 1.0 beta, now due in January. We've also pushed a major update to Ceylon Herd.
Another cool new features of the language is the assert statement. If
assertions doesn't sound that cool or new to you, then I bet you have not yet seen Ceylon's unique spin on the concept. You can read more about it at the Ceylon blog.
(P.S. I'm now mostly blogging over at the Ceylon site, and on Google plus, but I'll still post items here from time to time.)
