Bugfixes

• #5: Network requests aren't canceled when unfurling is canceled.

Breaking changes

• HtmlMetadataUnfurlerExtension#downloadHtml() is now suspending

Bugfixes

unfurl v2 brings support for kotlin coroutines, testability and several improvements to parsing of social tags.

Breaking changes

• TweetUnfurler was removed, thanks elon!
• Unfurler#unfurl() is now suspending
• Renames
  • UnfurlLogger.Println -> UnfurlLogger.println()
  • UnfurlLogger.NoOp -> UnfurlLogger.noOp()
  • HtmlTagsBasedUnfurler -> HtmlMetadataUnfurlerExtension
• UnfurlResult#contentPreview was removed in favor of UnfurlResult#extras, inspired by okio-filesystem

Unfurler extensions can now include arbitrary metadata in unfurled links using UnfurlResult#contentPreview. TweetUnfurler uses this to populate tweet details such as username, profile photo, media attachments, etc.

Breaking changes

• Renamed Logger to UnfurlerLogger and added an API to log exceptions that can be used with your error reporting service.
• Removed HtmlMetadataParser to simplify API surface. You're encouraged to create an extension instead by subclassing HtmlTagsBasedUnfurler.

• Follow HTTP redirects with the default OkHttp client (aaa6dd6)
• Use redirected URL in UnfurlResult instead of the original URL passed to Unfurler#unfurl (b11a15f)
• Use OkHttp 5.x in CLI
