llama.cpp Windows Manager v1.1.7

llama.cpp Windows Manager v1.1.7

v1.1.7 is a major release with multi-language support (21 languages), security hardening across process supervision, the API key lifecycle, and the model gateway, plus metrics accuracy improvements for parallel-slot workloads.

Multi-Language Support

• 21 languages now available in the sidebar language selector, covering ~96% of global users: Bulgarian (human-translated), plus 17 machine-translated languages at 87-98% coverage (Spanish, Russian, German, French, Japanese, Portuguese, Chinese, Italian, Turkish, Persian, Polish, Dutch, Vietnamese, Korean, Indonesian, Czech, Swedish). Arabic and Hindi use English fallback text pending native-script translations.
• All navigation buttons, page titles, column headers, field labels, dialog strings, status messages, tray menu items, and tooltip templates are now localised across all 530 translation keys. The language selection is persisted and applied immediately on app restart.
• English is always loaded as a fallback, so missing translations display gracefully in English rather than showing raw key names.

Security Hardening

• Custom parameter guard — User-supplied custom launch parameters can no longer override security-critical llama-server flags (--host, --port, --api-key). Attempting to do so now shows a clear error message.
• Native process cleanup — Native Windows llama-server.exe processes are now bound to a Windows Job Object with KILL_ON_JOB_CLOSE, so they are terminated automatically if the app crashes or is force-killed. Previously, native processes could become orphaned and continue running on their ports.
• API key lifecycle — Disabling API key authentication now clears the stored key from settings and triggers an OpenCode credential wipe (writes EMPTY to the provider config) instead of leaving the old key in plaintext.
• API key in process commands — The model API key is now passed via the LLAMA_API_KEY environment variable instead of a command-line argument, keeping it out of process command lines visible in Task Manager or WMI. For WSL launches, WSLENV forwarding is used to avoid embedding the key in the bash command string.
• Gateway upstream timeout — Added a 15-minute HTTP timeout on gateway upstream proxy requests to prevent thread-pool exhaustion during hung model inference.
• Null-byte rejection — WSL shell quoting (BashQuote) now rejects null bytes as a defense-in-depth measure against command truncation.
• Partial download cleanup — Cancelled or failed Hugging Face model downloads now delete their .partial files automatically, preventing multi-gigabyte orphaned files from accumulating in the models folder.

Metrics Accuracy

• Parallel-slot rate correction — The generation live rate now uses llama.cpp's reported active-generation seconds (tokens_predicted_seconds_total) instead of wall-clock time between polls. This prevents rate dilution when the model is idle between requests — a 2-slot session that generates at 35 t/s during bursts no longer shows an artificially low 13 t/s average during quiet periods.
• Newer llama.cpp support — The /slots endpoint parser now handles the current next_token object format (single object) in addition to the legacy array format, so per-slot generated-token counters are correctly populated across recent llama.cpp builds.
• Broader metric matching — Prometheus counter patterns expanded to match additional metric name variants (tokens_decoded_total, tokens_generated without _total suffix), improving compatibility with evolving upstream llama.cpp metric naming.

Localization Fixes

• Fixed navigation buttons showing raw key names (e.g. Nav.Overview) instead of translated labels on app restart with a non-English saved language.
• Fixed the language selector combo being empty on first launch after initialisation.
• Fixed active navigation highlighting breaking for non-English languages due to Loc.T() being used for internal page identifiers.
• Fixed the UpdatesNavButton label being overwritten with hardcoded English by the background update checker.
• Localised ~80 previously hardcoded English strings across page factories, view models, dialog factories, column headers, and status messages.

UI

• Added a visual separator between the language selector and the navigation buttons in the sidebar, matching the existing Tools section divider.

Build & Dependencies

• Bumped app metadata, visible UI version labels, and docs to v1.1.7.
• 19 new embedded localisation JSON resources added to the build.
• New ProcessJobObjectService infrastructure service for native Windows Job Object management.

Upgrade Notes

• Existing models, runtimes, logs, cache, state, and settings are preserved by installer update/repair and by default uninstall.
• No configuration changes are required. The language selector defaults to English; select another language from the sidebar dropdown to switch.
• This release is unsigned. Verify the .sha256 companion assets and expect Windows SmartScreen or publisher warnings until a trusted signing certificate is used.
