StreamCraft 0.12.1 — Voice chat, sharper screens, and a proper consent flow

This is a large step up from the last public release (0.9.9). The headlines: real-time voice chat, a wave of Display Block upgrades, a complete terms & age-gate consent flow, and broad cross-platform fixes for Linux and macOS. Everything new since 0.9.9 is summarized below.

🎙️ Voice chat (new)

Proximity-based, in-world voice — talk to nearby players or just your stream's viewers, no external app.

• Two modes: open proximity (distance-attenuated) or stream-bound (only your viewers hear you).
• Push-to-talk, open-mic, or voice-activated, with a mic-activity indicator. Opt-in — press M, off by default.
• Microphone & speaker selection, per-player volume sliders, and audio processing: echo cancellation, noise suppression, and auto-gain.
• Tuned for real distance — an adaptive jitter buffer keeps long-haul (e.g. transatlantic) calls smooth while staying low-latency on LAN.
• Ships on every Fabric band (1.20.1 through 26.1) and NeoForge.

🖥️ Display Blocks

• Auto-crop black bars. Letterboxed films and pillarboxed 4:3 sources now fill the panel cleanly — the block adopts the content's aspect ratio, no bars, no distortion.
• Pixel-precise positioning. Hold Shift while adjusting Distance/Horizontal to nudge by a single pixel, plus a new up/down vertical axis — screens sit exactly where you want them.
• Opaque backdrop. Shared screens and webcams are no longer see-through from behind.
• Cleaner, more compact Display Config screen.

📜 Terms, consent & age gate (new)

• A one-time Terms of Use screen the first time you turn on camera, screen share, share-to-web, or voice — links to the Terms, Privacy Policy, and Acceptable Use Policy, an age selection, and an explicit "I Agree," followed by a "How It Works" walkthrough.
• Children's-privacy protections: under-13 players can use on-device features only — nothing is transmitted to other people.
• Consent is withdrawable instantly: turn a feature off and transmission stops immediately. Nothing is recorded or stored.

🩹 Cross-platform fixes

• Linux: fixed Wayland/GNOME screen-share producing no video; fixed a hard crash the moment you published a webcam on some Intel GPUs; fixed received stream audio being silently dropped on PipeWire systems (now plays natively — no pipewire-alsa needed).
• macOS: screen shares recover automatically if the capture stalls mid-session, and the menu bar is no longer included in a shared screen.
• Desktop/system audio now reliably reaches viewers on screen shares.

🧩 Compatibility & polish

• Quilt Loader support for the Fabric builds.
• Fixed the Display Block crafting recipe failing to produce on Minecraft 1.20.5–1.21.1.
• HUD LIVE / MIC stream indicators repositioned to the top-left so they stay clear of vanilla potion icons and minimaps.
• A ♥ support page in the menu for backing the project.

Notes

• Run the same StreamCraft version on the client and the server — both must have the mod.
• This is the only supported StreamCraft release; earlier versions have been retired. Update both client and server to 0.12.1.
