Go
Google released a new system programming language. I wonder if the names of Robert Pike and Ken Thomsen will make it more appealing to C people 
It’s clearly meant to go head to head with C++. The two most interesting design decisions to me is their take on OO (feels like templates done right and no crappy inteheritance in the ordinary sense) and concurrency which looks a lot like Erlang because it’s CSP. Both of these things make it feel very functional.
So many languages to tinker with and so little time 
Oh yeah and it doesn’t run on Windows yet
