3.3.0 (2018-06-15)

GitHub sold us out. In the meantime, we:

• Migrated to BitBucket (to host repo + perform CI) and Codacy (for code quality audit)
• Dropped BitHound (RIP) and Travis
• Removed package-lock

3.2.0 (2018-05-14)

Improvements

• Now pointing unit tests at ES Modules build, not CommonJS-one. This means, unit test coverage will be correct (higher) because there won't be any missing rows that Babel added which are impossible to cover.
• Tweaks to ava config in package.json, properly enabling the dev Rollup builds.

3.1.0 (2018-04-29)

• Set up Prettier
• Removed package.lock and .editorconfig
• Wired Rollup to remove comments from non-dev builds. This means we can now leave the console.logs in the source code — Rollup will remove them during the builds.

3.0.0 (2017-11-22)

Changes

• Rewrote in ES modules, now serving UMD, Common JS and native ES modules builds. Bumping major just in case.
• Removed JS Standard and switched to raw ESLint on airbnb-base preset, with no-semicolon override.

1.0.0 (2017-05-22)

• First public release
