2.7.0 (2018-06-26)

• Updated dependencies, particularly, string-trim-spaces-only and others

2.6.0 (2018-06-20)

• Two range- dependencies have been renamed, namely ranges-push and ranges-apply. We tapped them.

2.5.0 (2018-06-11)

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

2.4.0 (2018-05-16)

• Tapped dependency string-match-left-right with its new {relaxedApi: true} option. This prevents throw errors in some edge case scenarios.

2.3.0 (2018-05-15)

• 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 from production code.
• Unit tests are pointing at ES modules build, which means that code coverage is correct now, without Babel functions being missed

2.2.0 (2018-03-27)

• Relaxed the API - if the input is non-string, it's just returned back.
• Switched from raw ESLint on airbnb-base preset to raw ESLint and Prettier.

2.1.0 (2018-02-14)

• Trimming now touches only spaces. Line breaks, tabs and non-breaking spaces are not touched.

2.0.0 (2018-02-13)

• Rewrote the whole thing. Added more unit tests.

1.0.0 (2018-01-11)

• First public release
