Somnia 12.2.0-beta.7

Somnia 12.2.0-beta.7 (pre-release)

Built from the full release-matrix CI run on the release commit: frontend e2e, native, macOS, Windows, Windows ARM64, Linux ARM64, all four CLI jobs, cli-checksums.

Highlights

• Studio lifecycle adapters: Slides, Photos, Sound, Video, Vector and Design now suspend in the background and resume from verified checkpoints - dirty documents keep their unsaved work through suspension and are never evicted silently.
• Session safety: Documents and Sheets write verified recovery checkpoints while you edit and restore them after a crash or a lost engine. Closing the window with unsaved edits now asks first and says whether a recovery copy exists.
• Transcript Hub: transcribe a browser-decodable audio file locally with the optional whisper.cpp helper and the existing ggml-base model (up to 10 minutes and 20 MB). Review and edit the text, export as TXT. No cloud fallback; builds without the helper refuse transcription.
• Job scheduler: application-owned job leases with priority lanes, bounded queues and byte reservations. Lifecycle pressure and resource profiles control admission; queued and running jobs protect engines from suspension.
• Extension idle-suspend: idle extension hosts suspend after 5 minutes (1 minute under memory pressure) and resume on demand, inside the lifecycle extensions budget.

Fixes

• 3D Studio e2e: viewport readiness is now a deterministic session signal, deflaking the intermittent KHR_texture_transform timeout.
• Transcript Hub controls use the design-system primitives.

Known issues

• Installers remain unsigned; SmartScreen and Gatekeeper can warn.
• No Intel macOS build (Apple Silicon only).
• Deploy, frameworks and the Somnia CLI remain experimental.
• Studio export/playback/AI call sites do not acquire job leases yet; they run outside admission control in this build.
• The Transcript Hub shows "unavailable" until an optional helper release is published for the platform.

Install

• macOS: Somnia-v12.2.0-beta.7-macos.dmg (Apple Silicon only, ad-hoc signed, not notarized; right-click > Open on first launch).
• Windows x64: Somnia-v12.2.0-beta.7-x64-setup.exe or -x64.msi. Windows ARM64: -arm64-setup.exe or -arm64.msi.
• Linux x64: -amd64.deb and -amd64.AppImage. Linux ARM64: -arm64.deb.
• CLI archives (Linux/Windows, x86_64 and aarch64) are attached (somnia-cli-*); keep sidecar/ next to the binary and install Node 20+ and git on PATH.
