## Release Bumps WebUI to `0.0.29`. Previous release tag: `v0.0.28` ## Changes since `v0.0.28` Features: - Ship version-matched AI authoring guidance with `@microsoft/webui`, using a lightweight skill that reads the installed package's reference (feat: bundle versioned AI guidance with WebUI #522 by @mohamedmansour). - Add plugin-aware component discovery, with filename-based HTML components and manifest-driven FAST components (feat: add plugin-aware component discovery #524 by @mohamedmansour). - Add WebUI Press `--show=all|content` for shell-free documentation views that preserve SSR, hydration, authored examples, and accessible theme behavior (feat: add WebUI Press content mode #525 by @mohamedmansour). - Automatically support Trusted Types for compiled templates and generated CSS import maps without promoting arbitrary state HTML to trusted content (feat: use Trusted Types automatically in the framework #536 by @mohamedmansour). - Keep explicit streaming imports lightweight so applications can load streaming support early and application code later (feat: keep explicit streaming imports lightweight #539 by @mohamedmansour). - Render tree-shaped state with file-scoped named `<for id="...">` bodies, including forward references and recursive reuse without extra client runtime code. Use unbraced `each="item in items"`; the legacy `template` spelling and FAST component references produce actionable diagnostics (feat: add file-scoped recursive for loops #547 by @mohamedmansour). Fixes: - Preserve table-rooted hydration ownership and correctly compile whitespace-bearing, nested directives, preventing duplicate controls after reactive updates. Rebuild templates to receive the compiler fix (fix: preserve table-rooted hydration paths #512 by @mohamedmansour; fix: align client directive parsing with the HTML scanner #531 by @mohamedmansour). - Emit reachable stylesheets and templates in deterministic traversal order. External plugin implementations must adapt the affected `HandlerPlugin` and bootstrap component collection interfaces from hash sets to slices (fix: render reachable-component ordering deterministically #519 by @janechu). - Resolve bare CEM module specifiers through their owning packages, respecting export maps, package boundaries, and cache invalidation when nearer dependencies appear (fix: resolve bare CEM module specifiers #528 by @janechu). - Prevent spurious dev-server rebuilds from read-only filesystem activity and recursive traversal of linked workspace dependencies (Improve benchmark telemetry and dev-server watching #521 by @mohamedmansour). - Update rustls to address TLS 1.3 handshake encryption-level validation advisory RUSTSEC-2026-0285 (fix: update rustls to address RUSTSEC-2026-0285 #533 by @mohamedmansour). - Forward bare boolean and ARIA component inputs into SSR state while preserving empty literal attributes and existing conditional boolean bindings (fix: forward HTML component inputs during SSR #540 by @mohamedmansour). - Preserve sibling route declaration order across SSR and client routing so equally specific routes select the correct pending and error boundaries (fix: preserve route order for pending and error boundaries #541 by @mohamedmansour). - Handle skipped or superseded router view transitions without unhandled animation rejections, while preserving route-commit errors and responsive subsequent navigation (fix: handle router view transition rejections #543 by @mohamedmansour). - Wait for active dev-server rebuilds and their bundler subprocesses before graceful shutdown, preventing output writes after the server exits (fix: wait for dev-server rebuilds during shutdown #546 by @mohamedmansour). - Preserve global theme defaults when custom properties are overridden only by scoped selectors or conditional rules, so unmatched component instances retain their intended colors (fix: preserve theme defaults under scoped CSS overrides #548 by @mohamedmansour). Docs: - Add a data-driven Benchmark Explorer, centralize performance guidance, distinguish independent SSR/browser metrics, and publish resource telemetry with accessible methodology details (docs: centralize performance guidance and benchmark data #486 by @mohamedmansour; Improve benchmark telemetry and dev-server watching #521 by @mohamedmansour). - Update AI reference installation and migration guidance while retaining `/ai`, and clarify plugin-specific discovery and FAST converted-template requirements (feat: bundle versioned AI guidance with WebUI #522 by @mohamedmansour; feat: add plugin-aware component discovery #524 by @mohamedmansour). - Document owned Rust partial rendering, streaming state ownership, and watcher hashing benchmarks, including measurement scope and tradeoffs (perf: reduce partial response allocations #510 by @mohamedmansour; perf: move streaming command processing off async workers #529 by @mohamedmansour; perf: bound watcher hashing memory with reusable scratch #530 by @mohamedmansour). - Document automatic Trusted Types support, CSP enforcement, and first-declared precedence for equally specific routes and their pending/error boundaries (feat: use Trusted Types automatically in the framework #536 by @mohamedmansour; fix: preserve route order for pending and error boundaries #541 by @mohamedmansour). - Explain named recursive loops and their compatibility limits, scoped CSS token defaults, and router view-transition error handling (feat: add file-scoped recursive for loops #547 by @mohamedmansour; fix: preserve theme defaults under scoped CSS overrides #548 by @mohamedmansour; fix: handle router view transition rejections #543 by @mohamedmansour). Maintenance: - Reduce partial-response and per-render allocations through owned state projection, borrowed graph traversal, scalar formatting, and borrowed nested route trees. Rust callers use ownership-taking `Protocol::render_partial(Value, ...)`; JSON boundaries retain `render_partial_json` (perf: reduce partial response allocations #510 by @mohamedmansour; perf: cut per-render handler allocations #511 by @mohamedmansour; perf: avoid cloning nested route trees #513 by @mohamedmansour). - Move streaming command deserialization, validation, and default preparation onto the existing blocking renderer, transferring owned records and state rather than cloning retained projections (perf: move streaming command processing off async workers #529 by @mohamedmansour). - Bound watcher hashing content storage to one reusable 8 KiB buffer instead of repeated file-sized allocations while preserving invalidation behavior (perf: bound watcher hashing memory with reusable scratch #530 by @mohamedmansour). - Parallelize release WASM builds and artifact staging, and consolidate dependency scanning before release jobs (chore: parallelize release pipeline work #509 by @mohamedmansour). - Refresh compatible Rust and JavaScript dependencies and migrate repository tooling and CI to pnpm 12.3.4 while preserving existing audit constraints (chore: update dependencies to latest compatible versions #534 by @mohamedmansour). ## Validation - `cargo xtask check` - `pnpm --dir crates/webui-press test` (16 passed). - `pnpm --dir packages/webui-framework exec playwright test recursive-repeat --workers=2 --reporter=line` (6 passed). - `pnpm --dir packages/webui-router exec playwright test --grep "view transition rejection ownership" --workers=2 --reporter=line` (4 passed).

Description
Custom Elements Manifests can aggregate declarations whose
modules[].pathvalues are bare npm module specifiers. Discovery previously treated every module
path as relative to the package containing the manifest, causing template lookup
to search beneath the wrong package and potentially abort package or scope
discovery.
This change:
nearest installed package;
and wildcard subpaths;
package that owns each referenced module;
cached discovery results.
Test Plan
CEM module paths.
exports.
ownership, path containment, and scope discovery failures.
overrides, and newly installed nearer dependencies.
