RAW mode can develop to a 16-bit working TIFF and optionally write a `*-developed.jpg` output while leaving the original JPEG untouched. +- Added **RAW development workflow** via RawTherapee **CLI** (`rawtherapee-cli`) with configurable extra args, better error reporting, output validation, and timeout handling. +- Added editor quality upgrades: **16-bit aware editing pipeline** using float32 working buffers, sRGB↔linear conversions for “true headroom” edits, OpenCV Gaussian blur helpers, and new **Texture** control. +- Added editor metadata display in the window title (filename + detected bit depth). +- Added robust undo/restore helper (`_restore_backup_safe`) to better handle locked files and tricky restore scenarios. +- Added support for indexing and displaying `*-developed.jpg` images and **orphaned RAWs** in the browser list; updated pairing test expectations accordingly. + +### Changed +- Reworked README installation instructions: + - macOS recommended flow with **Python 3.12** (Homebrew) + venv + `pip install .` + - Simplified run command (`faststack`) and clarified Windows/Linux steps. +- Switched RawTherapee path detection defaults from GUI executable to **CLI executable** on Windows/macOS/Linux. +- Improved Prefetcher decode behavior by using TurboJPEG **only for JPEGs**, with a Pillow fallback for non-JPEG formats or decode failures. +- Centralized navigation state changes (`_set_current_index`) and ensured edit mode resets appropriately on navigation (defaults back to JPEG unless RAW-only). + +### Fixed +- Fixed editor memory usage by clearing large editor buffers when the editor closes and resetting cached preview state. +- Fixed a QML slider double-click reset edge case where the slider could remain in a pressed/dragging state (force release via a short disable/reenable tick). +- Fixed histogram scheduling/thread-safety issues by tightening locking around pending/inflight state and improving failure handling when preview data is missing or executor submission fails. + + ## [1.5.0] -
