    First, thanks for all remarkably good internship applications we received. All positions are now taken, and our whole team is now working on exciting new features.

    The next version of OPA, scheduled for the end of March, will feature an extended, much improved standard library. We're also working on building a faster compiler and we hope it will be ready in time to be included in this next release. Stay tuned!
