Crystal Automated Release
Intro As we shared at the end of 2017, we restarted this year working on a plan towards 1.0. Our first stop was improving the automation of releases.

This is not a new year’s resolution
Almost 1 year ago, riding the wave of end of year optimism, Manas.Tech (“we” from here on in this post) decided to commit to wrap up a 1.0 release during 2017 that would include all possible breaking changes to the language.
