Somnia v12.2.0-beta.9

Highlights

Advanced export dialogs (AE2) across studios: PDF (editable copy, flattened print and screen copies, metadata), Animation (frame, sequence, GIF, APNG, WebM, sprite sheet), 3D (GLB, glTF, STL, OBJ, PNG still), Video (format, resolution, aspect, fps, quality, range), Sound (bit depth, channels, normalise, WAV tags) and Vector (format, area, exact size, background, metadata, live preview).
Video: named timeline markers (inspector list, timeline ticks, commands, project file), picture fade from and to black per clip, and per-clip colour correction (brightness, contrast, saturation).
Code studio: multi-cursor, delete-line and comment commands, plus line operations (sort, unique, trim, join, case).
Sound: automation curve shapes (linear, hold, ease) on all five lanes (session schema v15), copy rack to another target, reset insert parameters, delete rack presets, duplicate insert next to original.
Slides: icon picker that inserts icons as pictures, and PDF export of the deck.
Sheets: CSV/TSV import with delimiter detection, preview and targets.
Documents: footnotes and figure captions as managed text conventions.
Job leases now run video export, sound playback and agent turns; the signed extension blocklist is wired through with the maintainer-review mark.

i18n: added ext.blocklist keys to all five locale catalogues and completed the pt-BR advanced-export catalogue.
Documents: stopped truncated labels in the format bar.
UI: restored the accent primary button in confirm dialogs; styled the sheets CSV import dialog.
Preview: capped script-error traffic from looping pages in live preview.
Styles: pointed dead design-token references at canonical tokens; studio panels now share shell styles.

Interactive Windows/macOS launch and real-device feel tests remain unverified; CI checks are not a substitute. macOS is Apple Silicon only, ad-hoc signed and not notarized: Gatekeeper may require System Settings > Privacy & Security > Open Anyway. Do not disable Gatekeeper.
Collaboration remains alpha; LAN, relay, updater installs and real provider/model quality are not certified by offline tests.
This prerelease does not replace the Microsoft Store package.

Windows: setup.exe/MSI (x64 and ARM64). Linux: AppImage/DEB (amd64 and arm64). macOS: DMG (Apple Silicon), copy to Applications, follow the security exception above if offered.
