• Document::__construct now accepts \DOMDocument|string|null as its source.
• Document::serialize has been removed in favor of Document::saveHTML, making it more in line with PHP's DOM.
• Added Document::loadDOM for loading a vanilla PHP \DOMDocument into this library. As mentioned above Document::__constructor also accepts a \DOMDocument.
• Document::importNode will correctly convert an imported template element as a HTMLTemplateElement.
• TemplateElement is now HTMLTemplateElement.
• DOM walker methods now correctly check if the output of the closure is true
• Unnecessary test cases removed.
• Updated mensbeam/intl dependency.
• Moved scope methods from Element to OpenElementsStack. They don't need to be used outside of the parser and don't make sense there.
• Cleaned up parse errors. Displaying what is expected or found is not helpful.
• Changed DataStream from using an internal array storage to using /mensbeam/intl, much more efficient and in line with the specification.
• DataStream now calculates the line and column as it goes instead of relying upon a weird array of positions.
• Removed dependency on ext-intl.
