Headline: all audio is now encrypted (AES-256-GCM), keyed by a per-profile password. Mandatory — v3.3 only interoperates with v3.3+. Encryption - RemSoundCrypto (Core): PBKDF2 key derivation, AES-GCM encrypt/decrypt (low-alloc, into-span), password fingerprint, light on-disk obfuscation. - Wire: SenderLane encrypts the audio payload (PCM split across parts when the +28 overhead crosses MTU); AudioReceiver/StreamSession decrypt via a shared single-thread AudioDecryptor. Fingerprint piggybacks on the Format packet (offset 36, backward-compatible) so a peer can detect a password mismatch. - Profile.Password (scrambled), carried through BuildCurrentProfile; MainForm derives + pushes the key/fingerprint to sender + receiver (RecomputeAudioCrypto). - UX: ask-for-password on profile create; File -> Change this profile's password (ProfilePasswordDialog); Options -> Profile passwords (manager); a gate that prompts before streaming without a password; and a clear "passwords don't match" / "peer needs to update" message driven by the fingerprint. Cue fixes - CuePlayer (NAudio) replaces System.Media.SoundPlayer, which silently failed on the 96 kHz/24-bit cue WAVs (and any custom file) — cues now play reliably, resampled to 48 kHz/16-bit. Also fixes the Preferences preview button. - Connect/disconnect cues now audio-gated with hysteresis: connected when audio flows OR heartbeat healthy; lost only when audio stops AND heartbeat unreachable. Kills false disconnects and the receive-only "no cues" case. - Honest cue logging (played / muted / not loaded). Smaller - Endpoint stickiness: keep the audio target pinned to the heartbeat-proven address instead of chasing a multi-homed peer's other (unreachable) address. - "Online/offline" label now audio+heartbeat aware, not discovery-only. - "Show what's new after each update" preference (on by default). Docs: About v3.3 block, RELEASE_NOTES, README (encryption as a headline), manual section 12 "Passwords and encryption" (+ renumber), MANUAL.md regenerated. Version 3.2.0 -> 3.3.0.

C# fallback, which `new`s ~15 working buffers per encode call (issue #22 on the

Concentus repo, open since 2018) and produces ~4.5 MB/s of GC pressure per

encoding lane at 10 ms frames. Switching to native via this package keeps the

encoder state allocated once (C-side) and reuses it across calls. Same encoder

|
settings, bit-for-bit identical audio output. Installed at the top-level project

(per the package's install guidance) so `dotnet publish` correctly trims native

binaries for irrelevant RIDs from the release output. 2026-05-23. -->
