  • --llm-model-path <path>
  • --embeddings-model-path <path>
• KV-cache size controls to control how much of your system resources are allocated to inference generation. Default: --kv-size-mode auto
  • --kv-size-mode <auto|min|medium|max> (apply sizing by mode: auto | 33% | 66% | 100% of available limit)

​

Fixed

• Fixed intent resolution comparison.

​

Added

• Faster, more resilient networking: QUIC transport (opt-in) runs alongside TCP on the same port with automatic TCP fallback; upgraded to QUICv1 for lower latency and smoother handshakes.
• Connect through tough networks: NAT hole-punching (DCUtR) upgrades relayed links to direct connections with retry/backoff and Prometheus metrics for visibility.
• Smarter peer knowledge: PeerStore now tracks multiple addresses per peer to improve reachability.
• Configurable relay mode: Optional GossipSub relay acceptance/validation (off by default). Enable with FT_GOSSIPSUB_RELAY_ENABLED=true.
• Easier bring-up & testing: IPFS bootstrapping option; Docker Compose to run multiple nodes on one machine; Dockerfile now works with Podman.
• Better observability: New Prometheus metrics for DCUtR operations, peer analysis, and connection state.

​

Changed

• Less waste, better throughput: Participation logic tuned so a node skips very slow or ineffective rounds.
• Lower latency by default: Dialer prioritizes QUIC addresses when available.
• Cleaner logs: Error noise reduced where retries are automatic; clearer transport-type logging.

• Safer defaults: Updated node/network configuration; DCUtR is enabled conditionally via config.

​

Added

• Compatibility check: if nvidia-smi is missing and the system is not macOS, the app now shows System Incompatible notification.

​

Changed

• GPU-based systems will now always run GPU capsule.
• Simplified onboarding: Go to node button now closes the dialog instead of redirecting to another page.
• (macOS) Improved active window behavior:
  • App window always creates a menu bar entry.
  • When switching to app, a menu bar window is opened.
  • When launching the app when it is already running, its window is opened instead of launching another instance of the app.

​

Fixed

• Notifications:
  • Removed interaction options from notifications that have already been resolved.
  • Fixed globe icon color on notifications — it was invisible in light theme.

​

Added

• Bug reporting: System information is now collected and sent as a separate file (contained in the log archive) when submitting a bug report.
• Added “Documentation” item to the tray menu.
• (macOS) Launch Agent is now used instead of AppleScript for the auto-launch option — now the app should’t ask for additional permissions.

​

Changed

• (macOS) Updated app icons.
• Clarified titles in a few app messages.
• Adjusted memory check — it now uses available VRAM instead of total VRAM.
• VRAM warning is now triggered only if less than 2 GB of free VRAM is available.

​

Fixed

• Notification Center:
  • Some feedback messages no longer appear in the notification center for clarity.
  • Some warnings and critical notifications (e.g. Heavy Load, Connection Failed) will no longer duplicate if an active notification with the same code already exists.
• Fixed Connection Failed notification during onboarding – now only shown at the creation stage when an internet connection is actually needed.
• Fixed model list handling — now filtering out unnecessary models using the automation:false tag, they will no longer appear in automatic mode.
• Improved stability when losing internet connection:
  • When a download is interrupted due to lost connection, the model will no longer be mistakenly marked as downloaded and re-downloaded by the capsule.
  • Better separation of Connection Failed error states during node operation.
  • Reconnection notifications are now more stable both when the capsule is stopped and when it is running. It retries pings and disappears when connection is established; if automatically paused, it resumes automatically.
  • Service connection status no longer disappears after a timeout when offline — it now clears only after a successful ping or when the node connection issue is resolved.
  • Downloads now reliably restart once internet connection is restored (previously, this worked inconsistently).
• Fixed broken dock menu on macOS
• Fixed incorrect behavior of tray options in “Open in window” mode.
