Three reliability fixes — peer-address recovery, a reconnect crash, and a long-run memory/CPU leak. Wire format and audio pipeline are unchanged from v1.4 / v1.5 — all three releases interoperate.
- **Peer address recovery.** If the address you connected to stops responding — a peer rebooted onto a new IP, or a computer name resolved (via DNS / a router or Pi-hole record) to a stale address — RemSound now follows the peer to the live address it is still heartbeating from, instead of sending audio to a dead address indefinitely. Recovery is automatic within a few seconds. It only adopts private-network (LAN) addresses, so a relay's public address can never be mistaken for a moved peer.
- **Reconnect crash fixed.** When a peer reconnected — typically after rebooting — the Connectivity tab's peer list could be read mid-rebuild with a stale list index, throwing an `IndexOutOfRangeException` from the 1-second status timer and bringing the app down with a crash dialog. The list reads are now bounds-checked, and the status tick is wrapped so a transient UI hiccup is logged instead of fatal.
- **Long-run memory and CPU leak fixed.** A receiver left running for hours could grow to several gigabytes of memory and climbing CPU. Decoder sessions orphaned by peer reconnects (each reconnect creates a fresh stream identity) were not being reliably reclaimed — they piled up, each holding a multi-megabyte playout buffer and costing render-thread time on every audio callback. Idle sessions are now reaped on their own activity timer, with a hard cap on live sessions as a backstop, so memory and CPU stay bounded however long RemSound runs.
2. Extract somewhere with write permission (e.g. `C:\RemSound\`, `Documents\RemSound\`). Avoid `Program Files` unless you grant write permission so the self-updater can replace files in place.
If you installed RemSound inside a Dropbox-synced (or other file-sync) folder and your install is v1.0 / v1.1 / v1.2, see the [v1.3 release notes](https://github.com/Ednunp/RemSound/releases/tag/v1.3) for one-time manual install steps. From v1.3 onward Check-for-updates handles Dropbox correctly.
