# Changes to PostCSS Is Pseudo Class ### 2.0.6 (June 23, 2022) - Fix selector order with any pseudo element. - Fix transforming pseudo elements in `:is()`. Following the specification pseudo elements are invalid and we now transform to a known invalid pseudo element. - Add `onPseudoElement` plugin option. Set `{ onPseudoElement: 'warning' }` to receive warnings when this plugin encounters an unprocessable pseudo element. ### 2.0.5 (June 4, 2022) - Update `@csstools/selector-specificity` (major) ### 2.0.4 (May 17, 2022) - Fix selector order with `:before` and other pseudo elements. ### 2.0.3 (May 11, 2022) - Use `@csstools/selector-specificity` for specificity calculations. ### 2.0.2 (April 4, 2022) - Improved : compound selector order with pseudo elements - Improved : selector specificity calculation. ### 2.0.1 (March 4, 2022) - Preserve selector order as much as possible. Fixes issues where pseudo elements `::before` were moved. ### 2.0.0 (January 31, 2022) - Remove `skip` flag in `onComplexSelectors` option. If a complex selector is encountered that has no known equivalent, it will always be skipped and preserved now. The previous behavior was to remove `:is()` even if that broke the selector. ### 1.0.1 (January 17, 2022) - Fix selector order ### 1.0.0 (January 13, 2022) - initial release
