Somnia 12.2.0-beta.5

Somnia 12.2.0-beta.5 (pre-release)

Built from fully green CI runs on commit f9d28a4 (e2e suite run 39048817930 on c6a1832 plus harness-only pin, and the full release-matrix run 39060016007 on f9d28a4: frontend e2e, native, macOS, Windows, both CLI jobs, cli-checksums).

Highlights

• Agent panel: one conversation follows you across studios - stable conversation id, cross-studio history under the explicit "Reuse chat history" opt-in (off by default), tool offers follow the active studio (0105, 0109).
• Handoff hardening: Slides picture round-trip through Photos works end to end (opaque fixture, handback survives engine refusals, returned picture reaches slides.replaceImage as base64, deck identified by media name).
• Sound: AI proposal review names the settings-changes list for assistive tech; propose tool stays offerable to local models.
• Animation: APNG exports download as .png; stacked timeline keys cycle on click; timeline lane header wraps long layer names.
• Sheets: Excel-style cut/paste moves the block (cleared by Delete); Edit-in-Sheets handoff opens explicitly.
• Photos: opening a photo no longer crashes on the Light panel.

Fixes

• 3D: bevel segments forwarded through the viewport controller; multi-mark gizmo group pivot; area lights survive .som3d roundtrips; texture slot thumbnails render; remesh/sculpt command fixes; slow first-time viewport loads finish.
• Documents: render-time selection reads survive a caret ahead of block text.
• Code: per-file unsaved source tab status.
• Markdown: source editor regains focus after the reveal menu closes.
• Video: atomic I/O trim against render-loop re-sync.
• Agent: saved status rendered once, chip refresh regression fixed.
• Design system: dropped the stale class:diff hook (selector artifact, production unchanged).

Planned for beta.6

The following items from the beta.4 line are intentionally not part of this build and return in beta.6: session safety (crash-recovery checkpoints), settings transfer (export/import UI), studio lifecycle and jobs scheduling (performance controls), the in-app update channel, accessibility toolbar navigation, and native Windows ARM64 / Linux ARM64 builds.

Known issues

• Installers remain unsigned; SmartScreen and Gatekeeper can warn.
• No ARM64 builds in this release (Windows ARM64 and Linux ARM64 return in beta.6). No Intel macOS build.
• Deploy, frameworks and the Somnia CLI remain experimental.
• Known CI flake: chatUnread timeout (core tests) can intermittently fail a run; reruns pass.

Install

• macOS: Somnia_12.2.0_aarch64.dmg (Apple Silicon only, ad-hoc signed, not notarized; right-click > Open on first launch).
• Windows x64: Somnia-v12.2.0-beta.5-x64-setup.exe or -x64.msi.
• Linux x64: .deb and .AppImage.
• CLI archives (Linux/Windows, x86_64) are attached (somnia-cli-*); keep sidecar/ next to the binary and install Node 20+ and git on PATH.
