Changed

• The plugin now requires stylelint version 16.22.0 or higher.

v3.1.3

Compare Source

Fixed

• stylelint has been moved from dependencies to devDependencies. This may potentially fix some errors (see Stylelint's documentation regarding peerDependencies and PRs that explain the motivation behind this decision).
• postcss has been moved from devDependencies to dependencies. This fixes the “Cannot find package postcss” and “Named export Input not found” error in some environments.

Compare Source

Fixed

• An explicit end position is now passed to all report calls.
  The report calls no longer receive the line argument, which was deprecated in [email protected].

• Added an exception to the declaration-block-semicolon-space-before rule for an empty value of a custom property: now both --custom-prop: ; and --custom-prop:; are considered valid even with the never and never-single-line options.
  You can find a detailed explanation in the original issue (#​51) (@​MorevM).
