Summary

With over 35 new features, changes and bug fixes, Bit's v13 is focused on increased stability with over 20 bug fixes and support for common workflows including webpack resolve, tsconfig resolving, Vue resolve alias (Vue Webpack template) , Babel module resolver etc. Here are some of v13's highlights.

• add ability to configure custom module resolution in Bit (paths and aliases), to support absolute import statements for projects that use similar features using Webpack, Typescript, Babel, Vue alias etc. PR-#980, #852, #865, #869
• over 20 bug fixes including max call stack, import of binary files and more.
• environments transformed and refactored to act as native Bit extensions. PR-#931
• support "export X from Y" syntax of ES6 without importing X first. PR-#981
• support mixed mode of common-js and ES6. PR-#1036
• support Installing Bit using NPM using sudo. commit.
• introducing new flags for bit init including --reset and --reset-hard. PR-#1012

As a reminder, we're switching to major versions to indicate that we, like many others, have been using Bit in production for a long time. v13 follows the previous v0.12 and looking forward we'll continue to follow semver like we've done since 2016.
