私は、エピファニーがラズベリー pi のネイティブ Web ブラウザーであることに気付きました。ドキュメントは、エピファニーが html5 をより適切にサポートしていることに言及しています。しかし、エピファニーでサポートされているすべての html5 機能をどこにも見つけることができません。特に websocket のサポート。2015 年 3 月に新しいリリースが予定されているようです。ただし、html5 サポートに関するドキュメントはありません。エピファニーが webkit gtk モジュール上に構築されていることは知っていますが、この方法でもドキュメントが不足しています。
epiphany でサポートされているすべての html5 機能のドキュメントがどこにあるか教えてもらえますか? (特にウェブソケット)
ありがとうございました
