Version 2.0 — ground-up rewrite built on the geosam core library: Architecture: - Full backend rewrite — replaced in-plugin SAM implementation with the geosam core library - SAM backend switched to Ultralytics — model loading and inference now use the ultralytics SAM stack - Plugin-managed dependencies — installed into a plugin-private directory per QGIS runtime, no manual pip commands New Features: - Live Encoding mode — segment directly from a raster layer without pre-encoding; features are encoded on the fly via QGIS background tasks and cached for fast re-queries - Pre-encoded mode — use Image Encoder to generate reusable feature files for repeated segmentation of the same image - Online tile layer support — XYZ and WMS tile layers can be used in live-encoding mode - SAM2 and SAM3 model support — added the SAM2 and SAM3 model family alongside the original SAM - Vectorization mode — choose between Pixel-Level and Simplified polygon output - Max Polygon Only mode — keep only the largest polygon from the current mask - Unified Settings dialog — four tabs (Dependencies, Model Management, Cache, Help) - In-app Model Management — download, delete, and unload SAM checkpoints with Ultralytics + ModelScope fallback - Feature cache management — configurable cache directory, maximum size, performance mode (Balanced / Fastest / Low Memory) - Split-panel UI — Segmentation dock widget with Input/Output + Prompts on the left, Styles + Options on the right - Multi-language UI — translated into 中文, 日本語, 한국어, Français, Русский, العربية, Deutsch, Español, and Português Improvements: - PyQt6 / QGIS 4 compatibility - Faster prompt response via feature cache reuse - Better memory management (Balanced vs Low Memory strategies) - Preserved polygon holes when saving SAM results - Tab key cycles prompt types; keyboard shortcuts work even when widget is not focused - Preview Mode — SAM predictions follow the mouse cursor in real time Removed: - torchgeo and segment_anything as runtime dependencies - Minimum Pixels parameter from the Segmentation tool UI - Load Demo option (demo image no longer auto-loaded) - Manual pip dependency installation (replaced by Settings dialog)
