Hi everyone. It's been quite a while since we've done any major work on Fuel, so we are very excited to announce version 4.0.0 of Fuel today! Short-list of the most interesting things: - builder API - support for talents and anonymous classes - support for FullBlockClosure - full serialization support by default (no more need to load FuelMetalevel to serialize classes and methods) - full serialization support for Squeak The complete release notes are over on GitHub: https://theseion.github.io/Fuel/releases/4.0.0/. We hope that you'll like what we've done and we're excited to see, what kind of magic you will do with it. If you are using Fuel in a project, please let us know and we'll add it to the list of projects on GitHub (good for us and you ;)). As always, please report any issues to https://github.com/theseion/Fuel/issues and we'll try to help you out. Cheers, Max (on behalf of the Fuel team)
