v0.10.0

🚀 Release @addon-core/browser v0.10.0 (2026-10-11)

💥 Breaking Changes

• getSidebarPath now returns extension-local paths without a
  leading slash and preserves query parameters and fragments. isOpenSidebar
  without a window ID checks the last focused window and returns false when
  its state cannot be confirmed. isDownloadExists returns false for missing
  records and failed checks instead of undefined or a rejected Promise.

✨ Features

• api: add sidebar states and safe custom predicates (ad9ba40)

  Expose SidebarState and getSidebarState for open, closed, and unknown results.
  Normalize extension-local sidebar paths while preserving query and fragment.
  Make custom predicates return false when a condition cannot be confirmed.
  Preserve native proxy errors and strict lookups used by Action and downloads.

  Cover failure paths, browser profiles, public types, and ESM/CJS consumers.
  Document predicate contracts and reserve changelog updates for release-it.

• api: generate availability checks for all API modules (d997cad)

  Generate synchronous namespace checks for 27 browser APIs, deriving each
  export name from its namespace and returning false on unavailable globals
  or access errors. Preserve the three existing public availability names
  and share Action and Sidebar selectors with their methods.

  Encapsulate API descriptions behind default-export codegen entrypoints.
  Move event descriptions into events/apis and keep rendering algorithms
  separate from the common validation and file-writing runner.

  Cover availability behavior, generator entrypoints, public types, ESM/CJS
  consumers, and tree shaking. Update API documentation, contributor
  guidance, generation commands, and watch paths.

• api: generate event wrappers and standardize API modules (83f24a4)

  Move production APIs into src/api with separate method, event, and custom
  listener modules while preserving published package entrypoints.

  Generate 71 native event wrappers across 19 namespaces from shared and
  specialized templates. Check generated sources in CI and verify tree
  shaking against built-package consumers.

  Add onSpecificAlarms and onSpecificCommands map-based subscriptions.
  Subscribe notification listeners directly and retain an explicit
  availability check for callers.

  Fix sidebar capability detection, asynchronous error propagation, and
  window filtering. Align Opera setIcon declarations and the test harness
  with its optional callback signature.

  Cover methods, events, custom listeners, and consumer types, and update
  API documentation and contributor guidance for the new structure.

• bookmarks: add native methods and generated events (8dc0860)

• dnr: add native methods and generated event (d682a84)

  Add thirteen Dnr method wrappers, generated availability and debug subscriptions,
  and browser-specific types. Document native permissions and compatibility.
  Cover real network effects in Chromium and Firefox.

• search: add search API and browser integration tests (1b6a183)

  Add search helpers, capability checks, public types, and documentation.
  Verify native behavior in isolated Chromium and Firefox extensions.

  Run the browser suites in CI before publishing releases.

• tab-groups: add native methods and generated events (c89015a)

  Add four methods, generated subscriptions and availability, portable types,
  documentation and consumer checks. Cover the lifecycle and browser-specific
  payloads in Chromium and Firefox, including permission-denied profiles.

  Fix ungroupTab to use Firefox's Promise-only invocation while retaining
  callback support for the chrome facade.

• top-sites: add API wrappers and browser integration tests (887302b)

  Add getTopSites with Firefox options and generated availability checks.
  Cover native behavior, permissions, installed consumers, and tree shaking.
  Document the API using the shared reference format.

🐛 Bug Fixed

• api: normalize native calls and verify identity browser flows (2e9b1df)

• build: clean output before parallel tsup builds (8259d25)
