1.8.2

Released on Friday, September 18 2026

What's Changed

• Improved attribute selector serialization to write only the case-sensitivity modifier that was specified (#​1351)
• Improved id/name lookup on collections (document.forms["x"], form.elements["x"], ...) to enumerate the underlying sequence once instead of twice
• Improved performance of form.elements / fieldset.elements by walking the tree directly (#​1350)
• Improved GetElementsByTagName / GetElementsByClassName traversal to stop double-scanning each element's children
• Improved selector specificity (Selectors.Specificity, ComplexSelector.Specificity) to be computed once instead of recomputed on every read
• Improved ListSelector.GetMatchingSelector to sort its selectors once instead of on every call
• Improved performance of HTML tree construction by keeping mutation logic out of it (#​1347)
• Improved performance of DOM mutations by building a mutation record only when an observer will consume it (#​1347)
• Improved performance of parser attribute duplication check
• Fixed Document.Forms allocating a new collection instance per read, contradicting its own [DomSameObject] contract
• Fixed classList and the other reflected token lists writing their content attribute without running the attribute change steps or queueing a mutation record
• Fixed clearing a reflected boolean attribute such as disabled removing it without running the attribute change steps or queueing a mutation record
• Fixed vulnerability via SVG style serialization (GHSA-cgp3-27rh-pcp2)
• Fixed a StackOverflowException when parsing a document with deeply nested unclosed <template> elements
• Added Document.MutationVersion, a synchronous counter of DOM mutations that a parse leaves unchanged (#​1344, #​1347)
• Released 1.8.2 by @​FlorianRappl in Release 1.8.2 AngleSharp/AngleSharp#1353

New Contributors
