Improvements

• Added native XPath support with Element.selectXpath(String) #1629
• Added full support for the <template> tag, up to the HTML5 parser spec. #1634
• Added support in CharacterReader to track newlines, so that parse errors can be reported more intuitively. #1624
• Tracked parse errors now have more details, including the erroneous token, to help clarify the errors.
• Speed and memory optimizations for the :has(subquery) selector.
• The :contains(text) and :containsOwn(text) selectors are now whitespace normalized, aligning to the document text that they are matching against. #876
• In Element, speed optimized adopting all of an element's child nodes into a currently empty element. Improves the HTML adoption agency algorithm when adopting elements with many children. #1638
• Increased the parse speed when in RCData (e.g. <title>) and unescaped <tag> tokens are found, by memoizing the </title> scan and reducing GC. #1644
• When parsing custom tags (in HTML or XML), added a flyweight cache on Tag.valueOf(String) to reduce memory overhead when many tags are repeated. Also tuned other areas of the parser when many very deeply stacked custom elements were present. #1646

Bug Fixes

• The OSGi bundle meta-data incorrectly set a version on the import of javax.annotation (used as a build-time dependency for nullability assertions). #1616
• When tracking errors or checking for validity in the Cleaner, errors were incorrectly raised for missing optional closing tags.
• The Attributes.equals() method was sensitive to the order of its contents, but it should not be. #1492
• When the HTML parser was configured to preserve case, Element text methods would miss adding whitespace for BR tags.
• Attribute names are now normalized & validated correctly for the specific output syntax (HTML or XML). Previously, syntactically invalid attribute names could be output by the html() methods. Such attributes are still available in the DOM, and will be normalized if possible on output. #1474
• Bugfix [Fuzz]: fixed an IOOB when an empty select tag was followed by a body tag that needed reparenting. #1639

Build Improvements

• Fixed nullability annotations for Node.equals(Object) and other equals methods. #1628
• Added JDK 17 to the CI builds. #1641
