4.7.0 (2026-04-28)

Features

  • Support multiple targets in wait() (#68) (d229660)

4.6.0 (2026-04-28)

Features

  • Add filter callback option to restrict which matched nodes trigger the callback (#67) (e1bca5a)

4.4.0 (2026-04-28)

Features

4.3.0 (2026-04-28)

Features

  • add once option to watch() for callback-style one-shot observation (#64) (f799bbb)

4.2.0 (2026-04-28)

Features

4.1.0 (2026-04-28)

Features

  • make clear() return this to enable method chaining (#61) (7c7a7a1)

4.0.3 (2026-04-17)

Bug Fixes

  • Restrict CHANGE-only observer optimization to Element references (#59) (63d5369)

4.0.2 (2026-04-15)

Bug Fixes

  • Throw [TARGET] error on invalid CSS selector instead of propagating SyntaxError (#58) (60fed6f)

4.0.1 (2026-04-15)

Bug Fixes

  • Disconnect observer and clear timeout after wait() resolves (#57) (08f9251)

4.0.0 (2026-04-03)

Features

  • Move timeout/onError to watch(), remove continuous mode from wait() (#34) (2eaef59)

BREAKING CHANGES

  • wait() no longer accepts an onEvent callback. Use watch() instead.
  • onError removed from WaitOptions; moved to WatchOptions.

3.1.0 (2026-04-03)

Features

3.0.0 (2026-04-02)

Bug Fixes

  • Trigger major version bump for breaking changes (3836c92)

BREAKING CHANGES

  • watch() is a new dedicated method for recurring mutations. wait() with a callback still works but watch() is the preferred API going forward.
  • AbortSignal support added to both wait() and watch(). Passing an already-aborted signal to wait() now rejects immediately with an AbortError instead of starting observation.

2.1.0 (2026-04-02)

Features

  • Add AbortSignal support to wait() and watch() (#30) (2e26fcb)
  • Add watch() method for recurring mutation callbacks (#29) (2366741)

3.0.0-beta.2 (2026-04-02)

Features

  • Add AbortSignal support to wait() and watch() (#30) (17406c2)

3.0.0-beta.1 (2026-04-02)

Bug Fixes

  • Flag watch() as breaking change for correct semver bump (4a74e47)

BREAKING CHANGES

  • watch() shares the observer slot with wait(). Calling watch() rejects any pending wait() Promise with [ABORT] and stops any ongoing observation. Use separate instances for parallel observations.
