Johnson 2.0.0 prerelease 0

johnson version 2.0.0.pre0 has been released!

Johnson wraps JavaScript in a loving Ruby embrace. It embeds the Mozilla
SpiderMonkey JavaScript runtime as a C extension.

This prerelese is the first to include TraceMonkey, the evolution of
SpiderMonkey, which includes among other things a trace-based JIT
compiler for JavaScript.

Since it’s a pre-release, you need to give gem the --prerelease flag to
install it, i.e.,

gem install johnson --prerelease

Because it’s a prerelease gem, you may need to manually install gem
dependencies. The gem install will tell you if you need to.

The prerelease code is in the unstable branch of the git repo.
