Ruby 2.6.0 Preview 3 Released — The next step along the road to the (hopefully) eventual Xmas release of 2.6. The big news here is, as we’ve covered recently, the included initial ipmlementation of a JIT compiler, although overall performance is up slightly too. We also get endless ranges, then, and Bundler becoming a default gem.
