Release Notes

facelessuser/soupsieve

### [`v1.9.1`](https://togithub.com/facelessuser/soupsieve/releases/1.9.1) [Compare Source](https://togithub.com/facelessuser/soupsieve/compare/1.9.0...1.9.1) #### 1.9.1 - **FIX**: `:root`, `:contains()`, `:default`, `:indeterminate`, `:lang()`, and `:dir()` will properly account for HTML `iframe` elements in their logic when selecting or matching an element. Their logic will be restricted to the document for which the element under consideration applies. - **FIX**: HTML pseudo-classes will check that all key elements checked are in the XHTML namespace (HTML parsers that do not provide namespaces will assume the XHTML namespace). - **FIX**: Ensure that all pseudo-class names are case insensitive and allow CSS escapes. ### [`v1.9`](https://togithub.com/facelessuser/soupsieve/compare/1.8.0...1.9.0) [Compare Source](https://togithub.com/facelessuser/soupsieve/compare/1.8.0...1.9.0) ### [`v1.8`](https://togithub.com/facelessuser/soupsieve/compare/1.7.3...1.8.0) [Compare Source](https://togithub.com/facelessuser/soupsieve/compare/1.7.3...1.8.0) ### [`v1.7.3`](https://togithub.com/facelessuser/soupsieve/releases/1.7.3) [Compare Source](https://togithub.com/facelessuser/soupsieve/compare/1.7.2...1.7.3) #### 1.7.3 - **FIX**: Fix regression with tag names in regards to case sensitivity, and ensure there are tests to prevent breakage in the future. - **FIX**: XHTML should always be case sensitive like XML. ### [`v1.7.2`](https://togithub.com/facelessuser/soupsieve/releases/1.7.2) [Compare Source](https://togithub.com/facelessuser/soupsieve/compare/1.7.1...1.7.2) #### 1.7.2 - **FIX**: Fix HTML detection for `type` selector. - **FIX**: Fixes for `:enabled` and `:disabled`. - **FIX**: Provide a way for Beautiful Soup to parse selectors in a quirks mode to mimic some of the quirks of the old select method prior to Soup Sieve, but with warnings. This is to help old scripts to not break during the transitional period with newest Beautiful Soup. In the future, these quirks will raise an exception as Soup Sieve requires selectors to follow the CSS specification.
