Change Log

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

8.6.0 - 2016-11-22

• Update ESLint from 3.8.x to 3.10.x.
• 3 additional rules are now fixable with standard --fix!

8.5.0 - 2016-10-25

• Update ESLint from 3.7.x to 3.8.x.
• 2 additional rules are now fixable with standard --fix!

8.4.0 - 2016-10-10

• Update ESLint from 3.6.x to 3.7.x.
• 5 additional rules are now fixable with standard --fix!
• Use more conservative semver ranges #654

8.3.0 - 2016-09-29

The last release (8.2.0) added ES7 support. This release (8.3.0) adds ES8 support ...just 3 days later!

This release should eliminate the need to specify babel-eslint as a custom parser, since standard can now parse ES8 (i.e. ES2017) syntax out of the box. That means async and await will just work.

• Support ES8 (i.e. ES2017) syntax.

8.2.0 - 2016-09-26

For many users, this release should eliminate the need to specify babel-eslint as a custom parser, since standard can now parse ES7 (i.e. ES2016) syntax out of the box.

• Support ES7 (i.e. ES2016) syntax.
• Update ESLint from 3.5.x to 3.6.x.
• 4 additional rules are now fixable with standard --fix!

8.1.0 - 2016-09-17

• Update ESLint from 3.3.x to 3.5.x.
• Around 10 additional rules are now fixable with standard --fix!

8.0.0 - 2016-08-23

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!

New features

7.0.0 - 2016-05-02

Changes

• Upgrade eslint to version ~2.9.0
• Remove "rules" configuration option #367 from package.json (Reasoning is here)

New rules

Estimated % of affected standard users, based on test suite

Removed rules

• Require parens in arrow function arguments (arrow-parens)

6.0.8 - 2016-03-07

6.0.2 - 2016-02-06

• Internal change: Remove .eslintrc file, and use inline config

6.0.1 - 2016-02-05

• Internal change: Move .eslintrc file to root folder

6.0.0 - 2016-02-05

The goal of this release is to make standard faster to install, and simpler to use.

Remove standard-format (#340) (#397)

• Eliminates 250 packages, and cuts install time in half!
• For npm 2, install time goes from 20 secs —> 10 secs.
• For npm 3, install time goes from 24 secs —> 12 secs.
• To continue using standard-format, just install it separately: npm install -g standard-format

React-specific linting rules are removed (#351) (#367) (eslint-config-standard-react/#13)

• JSX is still supported, and it continues to be checked for style.
• There were only a few React-specific rules, but they made it extremely difficult for users of alternatives like virtual-dom or deku, and unecessarily tied standard to a single library.
• JSX rules come from eslint-config-standard-jsx. The eslint-config-standard-react dependency was removed.

New Rules

The percentage (%) of users that rule changes will effect, based on real-world testing of the top ~400 npm packages is denoted in brackets.

• Disallow __dirname/__filename string concatenation (#403) (no-path-concat) [5%]
• Require parens in arrow function arguments
 (#309) (arrow-parens) [5%]
• Ensure that new Promise() is instantiated with the parameter names resolve, reject (#282) (promise/param-names) [1%]
• Enforce Usage of Spacing in Template Strings (template-curly-spacing) [1%]
• Template strings are only allowed when necessary, i.e. template string features are being used (eslint got stricter: eslint/eslint#5147) [1%]
• Better dead code detection after conditional statements (eslint got stricter) [1%]
• Enforce spaces around * in yield * something (#335) (yield-star-spacing) [0%]
• Disallow labels on loops/switch statements too (made rule stricter) (no-labels) [0%]
• Disallow unnecessary constructor (no-useless-constructor) [0%]
• Disallow empty destructuring patterns (no-empty-pattern) [0%]
• Disallow Symbol Constructor (no-new-symbol) [0%]
• Disallow Self Assignment (no-self-assign) [0%]

Removed Rules

• parseInt() radix rule because ES5 fixes this issue (#384)
 (radix) [0%]

Expose eslint configuration via command line options and package.json

For power users, it might be easier to use one of these new hooks instead of forking standard, though that's still encouraged, too!

• Set eslint "plugins" (#386)
• Set eslint "rules" (#367)
• Set eslint "env" (#371)

To set custom ESLint plugins, rules, or envs, use the command line --plugin, --rules, and --env flags.

In package.json, use the "standard" property:

{
  "standard": {
    "plugins": [ "my-plugin" ]
  }
}

Upgrade to ESLint v2

• There may be slight behavior changes to existing rules. When possible, we've noted these in the "New Rules" and "Removed Rules" section.

Improve test suite

• Rule changes can be tested against every package on npm. For sanity, this is limited to packages with at least 4 dependents. Around ~400 packages.

Known Issues

• Using prerelease eslint version (2.0.0-rc.0). There may be breaking changes before the stable release.
• no-return-assign behavior changed with arrow functions (eslint/eslint#5150)

• standard (v5.4.1...v6.0.0)
• eslint-config-standard (v4.4.0...v5.0.0)
