[Unreleased]

[1.0.0] - 2026-09-12

Stable VDOM diff + hydration, router, CLI, testing, and benchmark/a11y
harnesses — all exit criteria satisfied. See docs/src/release-v1.md.
No API changes since 1.0.0-rc.1.

[1.0.0-rc.1] - 2026-09-11

Release candidate: the public API is frozen for 1.0.0. The only remaining
gates before the final v1.0.0 tag are non-codeable — production burn-in and
real-browser benchmarks (see docs/src/release-v1.md).

Added

• rustweb-testing::a11y: offline static accessibility audit returning
  severity-ranked, path-located violations with fix hints (rules:
  interactive-name, form-label, image-alt, heading-order,
  list-structure, landmark-main). Enforced through cargo test on every
  CI job.
• examples/todo-app: example_is_a11y_clean gates the shipped example to
  zero blocking a11y violations.

Changed

• docs/src/a11y.md and docs/src/release-v1.md updated: fuzz is validated at
  10M iterations and the a11y static audit is now a code-complete, PR-enforced
  exit criterion; the only remaining v1.0 gates are real-browser benchmarks and
  production burn-in.

[0.2.0] - 2026-09-11

Added

• crates/core: ComponentError::Panicked, RenderError::Panicked,
  run_guarded and run_render_guarded panic boundary (crates/core/src/runtime.rs).
• crates/core: UnnecessaryRenderDetector profiler and RenderSample payload
  for measuring view/patch time and skipping redundant renders
  (crates/core/src/perf.rs).
• crates/core: Scheduler with per-tick budget to keep Msg ping-pong loops
  recoverable (crates/core/src/scheduler.rs).
• crates/dom: Renderer::update that diffs, applies patches, and
  debug-asserts the committed tree equals the desired tree
  (crates/dom/src/renderer.rs).
• crates/dom: EventDelegator::root_listener_count — 100 bindings share 1
  root click listener (crates/dom/src/events.rs).
• crates/macro: html! rejects ARIA typos at compile time with Levenshtein
  suggestions (crates/macro/src/lib.rs).
• crates/router: LazyRoute factories run exactly once and are unit-tested
  (lazy_loads_once).
• tests/fuzz_diff.rs: deterministic fuzz harness (seed + iters) asserting
  apply-success rate and SSR match rate over 100k+ iterations.
• tests/ssr_golden.rs: golden-format tests freezing the SSR marker contract
  (data-rwh, data-rwe-*, data-rwh-checksum, <!--rwc:-->, <!---->).
• examples/todo-app: full runtime loop demo (create → view → Msg::Add/Toggle → update → diff → apply → SSR → verify_hydration) driven by Renderer.
• .github/workflows: release.yml (tag-triggered publish in dependency
  order), audit.yml (cargo-audit + cargo-deny + weekly schedule), docs.yml
  (mdBook + GitHub Pages), dependabot.yml (weekly cargo + actions).
• SECURITY.md, deny.toml, .github/CODEOWNERS, issue/PR templates.

Changed

• crates/dom/src/diff.rs: remove paths now use OLD-tree navigation while
  create/move/set paths use NEW-tree navigation. This eliminates cross-parent
  index drift when both structural and content patches coexist.
• crates/dom/src/diff.rs: mixed keyed/unkeyed child lists fall through to
  positional diff (documented limitation, no cross-parent structural ambiguity).
• Attribute diffing switched to ordered comparison; set_attr_at now
  remove-then-push so SSR attribute order stays deterministic and matches the
  post-patch tree.
• Root Cargo.toml: thiserror = "2" (2.0.20), rustweb-macro: syn = "3"
  (3.0.5). CI actions upgraded to checkout@v7,
  upload-pages-artifact@v5, deploy-pages@v5, action-gh-release@v3.
• All Markdown rewritten to professional English; comments stripped repo-wide.
• docs/book.toml language id → en.

Deprecated

• None.

Removed

• None.

Fixed

• GitHub Pages docs workflow: 403 on first upload because Pages was not
  enabled; switched mdBook installer to taiki-e/install-action@mdbook
  (peaceiris action pinned to deprecated Node 20).
• cargo fmt --all -- --check failures after comment stripping.
• 16 clippy warnings that had been silenced by -D warnings; resolved in
  source rather than with #[allow] (one exception:
  #[allow(clippy::derivable_impls)] on Default for Cmd to avoid
  introducing a spurious C: Default bound).

Migration (v0.1 → v0.2)

• No source-level breaking changes for user code. Public types, html!
  expansion, and SSR marker format are additive.
• If you pinned rustweb-cli build --features ssr, feature names are
  unchanged.
• If you rely on apply_patches_to_tree for cross-parent mixed structural
  patches, prefer calling Renderer::update (it owns the diff+apply pairing
  and debug-asserts committed==next).
