v3.3.3

Fixed

• Python enum KeyError (#324) — ConversionOptions() with default enums no longer crashes; PyO3 enum fields are passed directly instead of broken str() + map lookup.
• Ruby Magnus binding — fixed 65 compilation errors: funcall API, visitor bridge args, Vec conversion, optional flattening, sanitized field serde round-trip.
• Elixir .formatter.exs — 120-char line length, generated code passes mix format --check-formatted.
• Unused deps — removed serde_json from Node and WASM binding crates.
• Checkstyle — excluded test_apps/ from pre-commit checkstyle hook.

• Elixir NIF rustler 0.37 — replaced all removed APIs.
• Elixir type conversions — fixed double-optional wrapping.

v3.3.0

[3.3.0] - 2026-04-23

Added

• exclude_selectors option — CSS selector-based element exclusion. Unlike strip_tags (which removes the wrapper but keeps children), excluded elements and all descendants are dropped entirely. Supports any CSS selector: .class, #id, [attribute], compound selectors. Works in both markdown and plain text output modes.
• CLI flags — --preserve-tags, --skip-images, --max-depth for full ConversionOptions parity.
• Visitor pattern for all bindings (#314, #313) — restored visitor support across Python, TypeScript, Ruby, PHP, Go, Java, C#, Elixir, R, WASM, and C FFI.
• R visitor support — added visitor callbacks for the R binding.
• E2E test fixtures — 78 new fixtures for 100% ConversionOptions field coverage (35/35 fields). Added fixtures for exclude_selectors, ConversionResult.tables, and ConversionResult.warnings.
• Ruby RBS type stubs — auto-generated via alef from the Rust IR, including VERSION constant. Gemspec now includes sig/**/*.
• Alef pre-commit hook — alef-verify hook added to .pre-commit-config.yaml to check generated code freshness. CI installs alef v0.5.3 binary.

Fixed

• <h1> inside <header> not exported (#321) — top-level <header> elements were unconditionally dropped during preprocessing; now only <header> with navigation hints (e.g. class="site-header", role="navigation") is removed.
• PreprocessingPreset not wired into preprocessing logic — the preset field on PreprocessingOptions was defined but never checked. Now Minimal/Standard/Aggressive presets have distinct behavior.
• remove_forms flag was dead code — <form> elements are now dropped when remove_forms: true and preset is Standard or Aggressive.
• Aggressive preset — now drops navigation-hinted elements of any tag type, <noscript> elements, and noise-hinted elements (cookie banners, ad containers).
• Python NodeContent type — binding wrapper now implements Default, Serialize, Deserialize via forwarding to core type, fixing compilation when DocumentNode (which contains NodeContent) derives these traits.
• Python dict[str, Any] for data enums — NodeContent, AnnotationKind, VisitResult now use TypedDicts with Literal discriminators instead of untyped dicts.
• Python __init__.py exports — all public types now exported from the package.
• ImageMetadata.dimensions — tuple type (u32, u32) correctly maps to Vec<u32> / number[] / []uint32 in all bindings via serde round-trip conversion.
• FFI doc comments — multi-line doc strings on VTable struct fields now properly prefixed with /// on every line (was breaking cargo fmt).
• FFI optional parameters — visitor methods with optional string params (title, id, lang) correctly generate Option<&str> instead of &str.

[3.3.3] - 2026-04-23

Fixed

• Python enum KeyError (#324) — ConversionOptions() with default enums no longer crashes; PyO3 enum fields are passed directly instead of broken str() + map lookup.
• Ruby Magnus binding — fixed 65 compilation errors: funcall API, visitor bridge args, Vec conversion, optional flattening, sanitized field serde round-trip.
• Elixir .formatter.exs — 120-char line length, generated code now passes mix format --check-formatted.
• Unused deps — removed serde_json from Node and WASM binding crates.
• Checkstyle — excluded test_apps/ from pre-commit checkstyle hook.

[3.3.2] - 2026-04-23

Fixed

• Elixir visitor bridge — implemented async thread-based visitor protocol using rustler::thread::spawn + OwnedEnv::send_and_clear + mpsc channels, replacing the impossible synchronous env.call() approach.
• Elixir NIF rustler 0.37 — replaced removed SavedTerm, is_nil(), Pid::spawn_monitor, .encode() APIs with 0.37-compatible equivalents.
• Elixir type conversions — fixed double-optional wrapping (map(Some)) and ambiguous From impl in generated _from methods.
• Java checkstyle — added maven-checkstyle-plugin to pom.xml pointing to project checkstyle.xml (120-char limit), so mvn checkstyle:check uses our config instead of default Sun checks.
• Ruby Rakefile — explicit Bundler::GemHelper.install_tasks name: for Bundler 4 compatibility.

[3.3.1] - 2026-04-23

Fixed

• Java checkstyle — switched to 120-char line limit, added Spotless auto-formatting with Eclipse JDT formatter, added final params and javadoc to all generated code.
• Elixir list type collision — NodeContent::List variant no longer redefines Elixir's built-in list/0 type (now emits list_variant).
• Elixir NIF missing serde — added serde with derive feature as direct dependency to the NIF crate.
• C# VisitResult.Continue — default visitor methods now use new VisitResult.Continue() instead of non-invocable VisitResult.Continue().
• Node convert export — restored the missing #[napi] pub fn convert function dropped during binding regeneration.
• Ruby CI — updated Bundler from 2.7.2 to 4.0.3 to match Gemfile.lock.
