1.3.2 - 2026-05-19

🔒 Security

• HtmlAdapter URL scheme gate (defence-in-depth) — <img src> and <a href> are now routed through UrlSafety.isSafe (from hyper_render_core) after _resolveUrl runs. Even when callers bypass HtmlSanitizer (calling HtmlAdapter().parse(...) directly, or rendering with sanitize: false), javascript:, vbscript:, file:, mhtml:, about:, data:image/svg, and control-character smuggling variants now collapse to inert # (links) or '' (images). Mirrors the same gate the Markdown and Delta adapters already applied.

🚀 Performance

• HtmlAdapter.extractCss regex fast-path — for inputs ≥ 32 KB or with no <style tag at all (the common Markdown/Delta case), extractCss skips the full html5lib parse on the UI thread and uses a focused regex. Saves 50–300 ms on a 200 KB document on a mid-range Android, eliminating the synchronous parse stall that occurred on every initial render. Small inputs continue to use the full DOM parser for fidelity.

🧪 Tests

• +29 tests added across html_url_safety_test, css_parser_test, extract_css_perf_test. Covers scheme blocklist, smuggling, multiple <style> blocks, case-insensitive matching, fast-path threshold behaviour, comma/class/id selectors, keyframes round-trip.

🏗️ Maintenance

1.3.0 - 2026-05-03

• display: none: Elements with display: none are now correctly skipped — no more [edit] links leaking from Wikipedia-style HTML
• <pre> / code blocks: Inline code and code blocks now render via CodeBlockWidget
• <hr>: Renders as a styled BlockNode with a border instead of a LineBreakNode
• CSS Grid: display: grid with row/column track sizing, gap, and span support
• RTL/BiDi: direction: rtl for Arabic, Hebrew, and Persian content

🐛 Bug Fixes

• Whitespace preservation: Whitespace-only text nodes between inline elements no longer dropped — fixes missing spaces between <span> siblings
• appendChild for top-level nodes: Fixed parent reference not being set for top-level nodes added to the document root
• Shared ComputedStyle mutation: _defaultStyles map now returns .copyWith() copies — prevents cross-node style bleed
• Link XSS: javascript:, vbscript:, and data: hrefs are sanitized and blocked
• <details>/<summary>: Fixed double-render issue on expanded details elements
• @override analyzer warning: parseKeyframes() no longer carries @override annotation — flutter analyze reports 0 issues
• CSS float class detection: _containsFloatChild now detects Bootstrap/Tailwind float class patterns

🔬 Tests

• Added regression tests for display:none, <pre>, whitespace handling

1.2.0 - 2026-03-30
