Changelog

[Unreleased]

[3.0.0] - 2026-03-31

Added

• Added WASM support.
• HTML: added extended serialization API (serialize_ext).
• HTML: added scripting getter/setter; const for dom_opt getter.
• HTML: added <selectedcontent> element with spec-compliant disabled-state tracking.
• Style: new lxb_style_init()/lxb_style_destroy() API replacing lxb_html_document_css_init().
• DOM: new per-tag mutation dispatch tables — mutation (inserted, removed, moved, destroy, children_changed, connected) and attr_mutation (change, append, remove, replace) — replacing the old monolithic node_cb.
• DOM: added LXB_DOM_DOCUMENT_OPT_WO_EVENTS flag to suppress all mutation callbacks for plain parsing without overhead.
• DOM: added LXB_DOM_ELEMENT_CONDITION_DIRTY_STYLE for lazy style cleanup.
• Core: added new status LXB_STATUS_SKIPPED.
• Added support for pkg-config (lexbor.pc).
• Amalgamation: added cross-platform port support.
• Added const to certain function arguments across the API.

Changed

• Breaking: Style: replaced custom event system (lxb_style_event_*) with spec-compliant WHATWG DOM steps (element_steps, attribute_steps) using per-tag dispatch tables generated at build time.
• Breaking: DOM: document.node_cb replaced by mutation and attr_mutation callback tables.
• HTML: open_elements pop functions now return lxb_status_t and invoke per-tag callbacks.
• HTML: parse_cb mechanism removed; <style> parsing now happens through the pop callback in the Style module.
• HTML: <option> now tracks selectedness as a stored boolean field; insertion/removal steps update the nearest ancestor <select>.
• HTML: <select> implements the full WHATWG selectedness-setting algorithm, display size computation, and list-of-options tree walk.
• Packaging: updated DEB/RPM packaging for current distro standards.
