Changes since R1.0.0 RC2. CB1 0.5.

Dolby Vision

Improved scaled Master Reference rendering by removing a redundant full-resolution intermediate pass, without changing movie pixels, metadata or Kodi scaling filters.
Added software-decoded 10-bit AV1 Dolby Vision input using Kodi's existing uploaded textures. #85
Added an explicit active-area override for already-cropped files retaining incorrect L5 margins. Authored margins remain the default. #84
Added GPU bilinear FEL upscaling alongside Reference GPU. Master Reference retains its reference reconstruction filters.
Fixed playback freezing on the reported Saving Private Ryan FEL sample. The enhancement decoder now recovers forward after damaged data, preserves already decoded exact pairs and resumes at a verified random-access picture instead of waiting indefinitely.
Improved BL/EL pairing after Blu-ray seeks when both tracks contain unmatched preroll. Missing or ambiguous enhancement pictures are never replaced with neighbouring frames.
Aligned HDR10-to-Dolby Vision Adaptive processing with the DV-source Adaptive logic while retaining its AI-derived source statistics.
Kept independent playback preferences for Dolby Vision, HDR10 and HDR10+ sources. Automatic fallback no longer replaces the user's saved choice for the next file.
Added Kodi default consistently to the three playback selectors, leaving normal playback to Kodi without CB1 image processing.

Reworked HDR10 Expert renamed to HDR10 Rendering Reference around explicit display mapping: manually entered peak brightness, OLED/LCD/projector black presets or a custom black level, and output gamut selection.
Corrected near-black handling and creative-trim application to preserve shadow steps rather than applying a linear RGB offset that can crush them.
Added bounded highlight/gamut handling and coherent output metadata, including targets above the source mastering peak.
Improved HDR10 Rendering startup, resource ownership and transitions back from Dolby Vision; corrected the contrast-state issue reported during live switching.

Improved HDR10+ to Dolby Vision Rendering metadata mapping with weighted source-distribution estimates, bounded handling of incomplete statistics and continuous scene/seek state. Source video pixels remain unchanged by this metadata conversion. Weighted-percentile estimation adapted from AVDVPlus HistogramPlus.
Improved conversion startup and playback/seek recovery, with source metadata kept separate from estimated values.
Retained native HDR10+ playback through Kodi default, without activating the conversion pipeline.

Bundled the Java runtime and the BD-J JAR pair matching the native libbluray 1.5.0, avoiding the mismatch with older add-on JARs.
Fixed UHD menu video dimensions, missing/unknown video-size handling, audio/subtitle language selection and component inventories. Shared Java control fixes adapted from SamuriHL's CoreELEC work.
Improved direct-title stream inventory and BL/EL resynchronization without disc-name-specific workarounds.

Intel HDMI now identifies the source as a media player rather than a PC, avoiding LG automatic PC-mode and triggering Low Latency mode (#86). A driver override retains PC identification if required. Based on big-fella, via dangerouslaser.
Fixed an HDR10-to-Dolby Vision AI startup wait after fallback/re-entry by correcting the existing preparation order.
Fixed Intel HDMI link recovery with active HDR10+ metadata, retaining normal output validation. Contributed by lessbones in #83.
Improved return to SDR, live connector-state checks and output recovery after failed playback or mode changes.
Retained pending HDMI modesets until the requested timing is actually committed, including when Kodi temporarily reuses its last working configuration.
Improved AI frame/pool retirement, re-entry and paused-output resizing, without changing native Kodi scaling filters.
Added earlier NVIDIA driver-selection and boot diagnostics to distinguish driver initialization, connector selection and damaged boot media.
Corrected audio channel-map handling and retry state without adding artificial audio/video offsets.

Added optional optimized GUI compositing for compatible Dolby Vision output paths; movie pixels and metadata are unchanged. reducing GPU workload by 30% to render GUI on certain circuit
Clarified file metadata, metadata used by CB1 and metadata sent to the TV. Forwarded metadata is no longer misleadingly described as unused merely because CB1 does not apply it locally.
Clarified CM2.9/CM4 processing status, including live Auto/Auto 2 decisions.

Brief stutter or dropped frames may occur immediately after seeking.
Some backward-seek sequences on dual-track FEL MP4 files can stop playback; also reproduced on the previous RC3 build.
Disc-specific Java applications and repeated-disc memory behaviour are not universally qualified.
Some GTX 10-series , Intel Arc and NVIDIA RTX 50-series compatibility reports.
DV to HDR10+ need to be refined
