+      "Update channel in Settings → Updates: Stable, or Dev for test builds; Dev stays on test builds after a release and still gets the newer release when there is one",
+      "Sharper subtitles and picture: the video and its subtitles are drawn at your screen's resolution instead of the video's (Settings → Player → Sharp video and subtitles, on by default)",
+      "Invite links: Invite copies just a starsync:// link, password included, so a friend just clicks it (or copies it and switches to Starsync) and the app asks \"Join Bob's server?\"",
+      "Invite finds your internet address on its own and says when your router needs the port forwarded; Other addresses picks your home-network or VPN address instead",
+      "Starsync runs once: a link clicked while it is open goes to the open window",
+      "Quick chat: press Enter in the big player to type a message in a small box at the bottom, without opening the chat panel and without the mouse pointer or the controls popping up; it shares its draft with the chat panel, closes by itself when you stop typing, and subtitles move up out of its way",
+      "Danmaku notifications: chat, joins, leaves and Up next can fly across the top of the picture instead of popping up (Settings → Notifications & sounds → Notifications: Danmaku, off by default), with speed, how many at once, where, opacity, size, boldness, outline and avatars all adjustable and a live preview",

+      "Joining while something plays on Windows: the video opens again by itself when it was too early",
+      "Relay: players no longer get stuck after a slow or stalled source",
+      "Relay: X (Twitter) clips play through the relay",
+      "Relay: gentler retries, so Bilibili stops blocking the server",
