+## Dependencies
+
+-   updated `stylelint` from `^13.7.2` to `^14.5.0`
+-   updated `stylelint-config-standard` from `^20.0.0` to `^25.0.0`
+-   updated `stylelint` peer dependency to `^14.4.0`, i.e. removed support for older versions
+-   added `stylelint-config-prettier` dependency
+
+## Changes to linting rules
+
+-   increased `max-nesting-depth` to 4.
+
+-   added rules:
+
+```js
+'at-rule-disallowed-list': ['debug'],
+'selector-type-no-unknown': null,
+'function-no-unknown': null,
+'no-empty-source': null,
+```
+
+-   removed duplicate rules that were or became standard in stylelint-config-standard or stylelint-config-recommended:
+
+```js
+'property-no-vendor-prefix': true,
+'at-rule-no-vendor-prefix': true,
+'selector-no-vendor-prefix': true,
+'value-no-vendor-prefix': true,
+'function-url-quotes': 'always',
+'font-family-name-quotes': 'always-where-recommended',
+'selector-attribute-quotes': 'always',
+```
+
+-   by adding `stylelint-config-prettier`, all rules that might cause conflict when using prettier are disabled.
+
+-   disabled all stylistic rules as recommended by stylelint [here](https://stylelint.io/user-guide/rules/list/#stylistic-issues), by changing
+
+```js
+'max-empty-lines': 2,
+'string-quotes': 'single',
+'value-keyword-case': [
+  'lower',
+  {
+    ignoreProperties: ['font-family', '/^\\$font-family-.*/']
+  }
+]
+```
+
+to
+
+```js
+'max-empty-lines': null,
+'string-quotes': null,
+'value-keyword-case': null,
+```
+
+-   and by adding the following to disable all other stylistic rules which might come with stylelint-config-standard. Those should be handled by a pretty printer instead.
+
+```js
+'function-name-case': null,
+'custom-property-empty-line-before': null,
