Release Notes

AngleSharp/AngleSharp (AngleSharp)

v1.8.6

Released on Sunday, October 25 2026.

• Removed temporary copies when serializing text that needs no HTML escaping
• Fixed INode.Equals (isEqualNode) to compare what the DOM spec compares: character data, doctype identifiers, processing instructions, element prefixes and attribute local names, no longer base URLs, without overflowing the stack on deep trees
• Fixed IAttr.Equals comparing the prefix instead of the local name
• Fixed IDocument.Import (importNode) returning nodes owned by the source document instead of the importing one
• Fixed IDocument.Import accepting a shadow root instead of throwing NotSupported
• Fixed INode.Clone and Import overflowing the stack on deeply nested trees and templates
• Fixed a shallow clone of a <template> copying its contents
• Fixed serializing < and > in attribute values unescaped, which let markup break out when reparsed under different rules (mutation XSS); they are now written as < and > like browsers do since the HTML spec change of May 2025
• Fixed IRange.CopyContent and ExtractContent overflowing the stack on deeply nested ranges
• Fixed Dispatch (dispatchEvent) returning true for a canceled event
• Fixed MutationObserver not observing a document itself and throwing for one without a root element
• Fixed MutationObserver.Disconnect keeping the previous targets for a later Connect
• Fixed a failing navigation or submission from DoClick crashing the process; it is reported as a context error
• Fixed URLSearchParams treating non-ASCII values as single bytes and leaving + undecoded @​NotAFlightRisk
• Added the IHtmlSelectElement.SelectedIndex setter
• Added HtmlParserOptions.MaximumDepth (default 512) to stop deeply nested markup from building trees that overflow the stack
• Added focusing of elements with a tabindex and blurring of any focused element
• Added DoClickAsync to await a click's navigation or form submission
• Added toggling the parent <details> when clicking its <summary>
• Added declarative shadow DOM: the parser attaches <template shadowrootmode="open"> (or closed) as the shadow root of its parent
• Added :host(<compound>), and selectors in a shadow tree reaching its host (only through :host)

bUnit-dev/bUnit (bunit)

v2.13.3

Fixed

• Find threw TypeLoadException with AngleSharp 1.8.6 because HtmlSelectElementWrapper did not implement the new SelectedIndex setter. Reported by @​poxet in #​1957. Fixed by @​linkdotnet.
• A WaitFor* call whose first check passed left its timeout timer running, which kept the helper, the renderer and everything the renderer holds alive until the timeout elapsed. With a long DefaultWaitTimeout, a test suite could hold every rendered component in memory for its whole run. Fixed by @​xaviergxf.
