• Microbundle now uses the .mjs file extension for JS Module files, and will auto-detect them as source code.
• Update to the latest and greatest Rollup.

Special thanks to @Andarist and @ForsakenHarmony for their awesome work keeping Microbundle moving forward! 🙇‍♂️

• Breaking Change: --external all is now the default. Modules listed in your package.json's "dependencies" and "peerDependencies" will be linked as imports/require statements (thanks @Andarist)
• Importing subdirectories from packages now treats them as external (#83, thanks @Andarist)
• When builds fail, actually output some useful information (#120, thanks @jesstelford)
• Output much more helpful Rollup errors (#128, thanks @gribnoysup)

• Add .tsx support! (thanks @jaredpalmer)
• Updated to Rollup 0.60+
• watch mode can now also be activated via a --watch flag (thanks @ngryman)

• New API: options.onBuild. You supply a function, it gets called on each build in watch mode (thanks @fwilkerson)
• Switch to rollup-plugin-typescript2 🔥 (thanks @freeman)
• Add --source-map option (use --no-source-map to disable them, thanks @cristianbote)
