v2026.1.0

The downloadable image went from about 2.4 GB to about 100 MB: about 95.8% smaller, or about 24x smaller.
Major API and UI refresh with faster loading, stronger invalidation/realtime updates, and broader device/system state coverage.
Stream workflows were reworked across registration, calibration, recording, and media handling.
Localization and peers flows were hardened for seeded maps, pose handling, validation, and multi-source operation.
Camera defaults and platform integration improved, including OV9782 tuning, libcamera fixes, startup/networking/persistence fixes, and Windows USB link fixes.

Reduced downloadable image size from about 2.4 GB to about 100 MB: about 95.8% smaller, or about 24x smaller, than v2026.0.0.
Reduced installed on-device footprint from about 7 GB to about 180 MB: about 97.4% smaller, or about 38.9x smaller.
Reduced average RAM use from about 1 GB to about 250 MB: about 75.0% lower, or about 4x lower.
Reduced idle CPU usage from about 15% to about 2%: about 86.7% lower, or about 7.5x lower.
Reduced idle resource burn and continued memory footprint cleanup across the image and services.
Fixed startup, persistence, dependency-upgrade, and networking issues that affected bring-up and long-running stability.
Expanded system/device surfaces for revision, storage, metrics, bootloader, logs, and health reporting.

Continued the API overhaul with new read-model plumbing, better invalidation, faster request paths, and stronger realtime updates.
Expanded WebSocket coverage for runtime data, including sensor and IMU streams.
Refined frontend data access and pipeline/stream UI plumbing for outputs, metrics, and device state.
Renamed the old snapshots support workflow to Diagnostics, with updated UI/docs terminology.

Seeded sharper OV9782 defaults for new streams and tuned denoise/sharpen behavior.
Improved stream registration and camera-page behavior, including responsive calibration/controls layouts on smaller screens.
Relaxed calibration solve gating and improved advisory guidance during calibration and stream-quality work.
Fixed upload and camera-page UI bugs and hardened recording/media workflows.

Fixed localization pose issues and hardened seeded field-map bootstrap behavior.
Improved localization source handling, validation, and pipeline integration for more reliable multi-source operation.
Continued improvements to peer discovery/registration and related networking flows.

Fixed libcamera IPA install failures that could block image startup.
Fixed Windows USB link handling issues.
Improved backend validation coverage around streams, calibration, and related runtime workflows.
