 ## [Unreleased]
 
+## [0.6.4] — 2026-07-18
+
+### Added
+- **Chat now tells you when a message didn't send.** A message that couldn't go
+  out — because you weren't in a room, or the broadcast failed — is marked
+  **"⚠ Not sent"** with a **Retry** button, instead of sitting in the transcript
+  looking delivered. A successful send shows nothing (PeerSpeak has no
+  delivery/read receipts, so anything else would be a false promise).
+- **Fast typing no longer loses messages.** When you fire off a quick burst,
+  messages past the first few are held as **"queued…"** and sent a moment apart,
+  matching the rate other people's clients accept. Previously a fast burst could
+  look sent on your end while some messages silently never reached the room.
+
+### Changed
+- **Tidier music playlist drawer.** The slide-out playlist no longer repeats the
+  play/skip controls already on the player bar, and the track list now grows to
+  fill the drawer instead of being boxed into a short scroll area, so you can see
+  more of your playlist at once.
+- **Safer chat under the hood.** A round of chat hardening tightened how incoming
+  messages, display names, links, and file/image attachments are validated and
+  bounded, so a malformed or hostile message from a peer can't spoof a name,
+  replay, flood, or run the app out of memory. No change to how normal chat looks
+  or works.
