Somnia 12.2.0-beta.6

Somnia 12.2.0-beta.6 (pre-release)

Built from the full release-matrix CI run 39130472086 on commit 395987f: frontend e2e, native, macOS, Windows, Windows ARM64, Linux ARM64, all four CLI jobs, cli-checksums.

Highlights

• Update channel: signed stable/beta/alpha channels in-app. Beta and alpha builds now install prerelease updates directly from the app; channel manifests (latest.json, latest-beta.json, latest-alpha.json) are published with each release.
• Studio lifecycle: the lifecycle subsystem lands on this line - studios suspend and resume instead of staying resident, cutting idle memory and CPU.
• Session safety: verified crash-recovery checkpoints restore your session after an unexpected exit.
• Settings transfer: export your setup and import it on another machine, with a reviewed apply step before anything changes.
• Accessibility: keyboard navigation and contrast pass across the shell, including toolbar navigation announced in beta.5.
• Native ARM64 builds are back: Windows ARM64 and Linux ARM64 installers and CLI archives ship with this release.
• Sheets: filter slicer with date-aware values and table binding, filter timeline (date-period view, current-period pick, table binding), half-open numeric range filter op, and the duplicated value-list filter removed from the Layout panel.

Fixes

• Sheets: filter mirror readback per column, matching the engine's criteria accumulation; timeline seeds its period ticks from the session filter mirror.
• E2E: the full Playwright suite now runs sharded four ways in a dedicated job; rail toolbar labels resolve per locale in the i18n finish pass.
• Shell: removed stray role=status landmarks that shadowed the shell announce region.

Planned next

Per-studio lifecycle adapters (Slides, Photos, Sound, Video, Vector, Design stay resident today), the job-scheduler bridge with a pressure hook, and extension idle-suspend return in a following beta.

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.
• Known CI flake: studio3d:264 (KHR_texture_transform) can intermittently fail a run; reruns pass.

Install

• macOS: Somnia-v12.2.0-beta.6-macos.dmg (Apple Silicon only, ad-hoc signed, not notarized; right-click > Open on first launch).
• Windows x64: Somnia-v12.2.0-beta.6-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.
