sse_channel 0.2.0 changelog

0.2.0 #

Breaking: SseChannel.stream now emits Event objects exposing data, event, and id metadata rather than raw strings.
Improved IO client compliance with the WHATWG SSE spec: preserves Last-Event-ID, honors retry: hints, sends Cache-Control: no-cache, and retries automatically.
Surface connection and send failures as SseChannelException for both IO and HTML implementations and re-export the type for package users.
Added HtmlSseChannel.test to make browser-specific code testable without a real network connection.
Expanded test coverage with extensive unit tests for the event transformer, IO reconnect flow, and browser behaviour.
