8.0.0

This release is accompanied by:

• A new semantic version policy. The use of the tilde (~) in package.json is now recommended, e.g. "stylelint": "~8.0.0", to guarantee the results of your builds (#1865).
• A new VISION document, complemented by (#2704):
  • The restructuring of the list of rules into three groups:
    • Possible errors.
    • Limit language features.
    • Stylistic issues.
  • The release of a new sharable config, stylelint-config-recommended. This config only turns on the possible error rules. stylelint-config-standard now builds on top of the recommended config by turning on over 60 additional stylistic rules.

7.8.0

• Deprecated: 15 rules (#2197, #2285 & #2309).
  • block-no-single-line. Use block-opening-brace-newline-after and block-closing-brace-newline-before rules with the option "always" instead.
  • declaration-block-properties-order. Use the stylelint-order plugin pack instead.
  • rule-nested-empty-line-before and rule-non-nested-empty-line-before. Use the new rule-empty-line-before rule instead.
  • time-no-imperceptible. Use the new time-min-milliseconds rule with 100 as its primary option.
  • It is beyond the scope of stylelint's core package to effectively validate against the CSS spec. Please investigate csstree and css-values for this functionality, and contribute to those projects and to stylelint plugins wrapping them. csstree already has a stylelint plugin, and css-values needs one to be developed. The following rules are deprecated for this reason.
    • media-feature-no-missing-punctuation.
    • selector-no-empty.
  • A plugin is a better package for a rule that wraps a third-party library. The following rules are deprecated for this reason. We encourage users to create and help maintain plugins for these rules.
    • no-browser-hacks
    • no-indistinguishable-colors
    • no-unsupported-browser-features
  • The following rules did not seem useful. If you liked these rules, please create plugins for them.
    • custom-property-no-outside-root

  • "all-nested" option for at-rule-empty-line-before. Use the "inside-block" option instead.
  • "blockless-group" option for at-rule-empty-line-before. Use the "blockless-after-blockless" option instead.
  • "between-comments" option for comment-empty-line-before. Use the "after-comment" option instead.
  • "at-rules-without-declaration-blocks" option for max-nesting-depth. Use the "blockless-at-rules" option instead.

• Removed: --extract and extractSyleTagsFromHtml options. Instead, build and use processors.

• Removed: --verbose CLI flag. Use --formatter verbose instead.
• Removed: NodeJS 0.12.x support. 4.2.1 LTS or greater is now required.
• Removed: media-query-parentheses-space-inside rule. Use the new media-feature-parentheses-space-inside rule instead.

• Changed: .stylelintignore now uses .gitignore syntax, and stylelint looks for it in process.cwd().
• Changed: files matching ignore patterns no longer receive an "info"-severity message, which was always printed by the string formatter. Instead, the file's stylelint result object receives an ignored: true property, which various formatters can use as needed. The standard string formatter prints nothing for ignored files; but when the verbose formatter is used, ignored files are included in the filelist.

• Changed: font-family-name-quotes treats -apple-* and BlinkMacSystemFont system fonts as keywords that should never be wrapped in quotes.

If you do not want to check inside of parentheses, use the new ignore: ["inside-parens"] secondary option. The indentInsideParens: "twice" and indentInsideParens: "once-at-root-twice-in-block" secondary options are unchanged.
