v2.0.0

2.0.0 (2026-04-28)

⚠ BREAKING CHANGES

• tune() now resolves with a Blob, not a data URL
  string. Use URL.createObjectURL(blob) for previews, or call the new
  tuneToDataURL() helper for v1-compatible behavior.
• gif and avif are removed from the OutputFormat union.
  canvas.toBlob('image/gif') silently fell back to PNG in every browser
  in v1 (so it never actually emitted GIFs), and no production browser
  encodes AVIF via canvas as of early 2026. Pass 'png' or 'webp' instead.
• errors now reject the returned promise instead of
  silently hanging. Callers without .catch on tune()/tuneToDataURL()
  that relied on the v1 silent-failure behavior must now handle errors.
• the default export was removed in favor of named
  exports. var ImageTune = require('imagetune') no longer works as a
  namespace; use const { tune, tuneToDataURL, ImageTune } = require(...)
  or import { tune } from 'imagetune'.
• the published distribution is now ESM + CJS via the
  exports map. The bare index.js and index.html at the repo root no
  longer exist. Bundlers should resolve correctly via the new exports
  field; <script src> users should target the unpkg/jsdelivr URL.
