standard - npm Package Versions

This release contains a bunch of goodies, including new rules that catch potential programmer errors (i.e. bugs) and enforce additional code consistency.

However, the best feature is surely the new --fix command line flag to automatically fix problems. If you ever used standard-format and ran into issues with the lack of ES2015+ support, you'll be happy about --fix.

standard --fix is built into standard v8.0.0 for maximum convenience, it supports ES2015, and it's lightweight (no additional dependencies since it's part of ESLint which powers standard). Lots of problems are already fixable, and more are getting added with each ESLint release.

standard also outputs a message ("Run standard --fix to automatically fix some problems.") when it detects problems that can be fixed automatically so you can save time!

With standard v8.0.0, we are also dropping support for Node.js versions prior to v4. Node.js 0.10 and 0.12 are in maintenance mode and will be unsupported at the end of 2016. Node.js 4 is the current LTS version. If you are using an older version of Node.js, we recommend upgrading to at least Node.js 4 as soon as possible. If you are unable to upgrade to Node.js 4 or higher, then we recommend continuing to use standard v7.x until you are ready to upgrade Node.js.

Important: We will not be updating the standard v7.x versions going forward. All bug fixes and enhancements will land in standard v8.x.

Full changelog below. Cheers!
