It's designed for two main audiences: Go developers who want low-level control without having to learn another language. C developers who like Go's style. At the end of the v0.2 post, I said the obvious goal for the next release was concurrency, along with the stdlib packages that support it. That's what v0.3 is about. So now has threads, channels, worker pools, mutexes, and atomics — enough tools for parallel data processing or handling network connections. This release also adds a streaming JSON package, a bunch of safety checks (escape analysis, leak checking, nil-pointer panics, stack traces), and proper so test and so bench commands.
