Mar 1, 2025March 2025 (2025-03) monthly summary for girder/large_image: Delivered two major feature sets and code-quality improvements that enhance UI responsiveness, caching behavior, and geospatial defaults. The histogram request workflow in CompositeLayers.vue now supports debounced, per-frame queued requests with deduplication, significantly reducing UI thrash during rapid data updates and preserving current visualization state. Tile source defaults and LRU caching improvements centralize default_encoding and default_projection, apply defaults only to geospatial sources, strengthen caching correctness via updated getLRUHash logic and a PROJECTION_SENTINEL, and include tests and documentation for maintainability. Overall impact: improved user experience, reduced server load, and safer defaults for geospatial data.

Feb 1, 2025February 2025 monthly summary for girder/large_image focused on delivering interactive visualization features, stabilizing editing and data I/O pipelines, and expanding test coverage to reduce regressions. Key features shipped include a rectangle drawing tool in the ipyleaflet viewer, histogram editor enhancements (real min/max when autoRange, tooltips on handles, and snapping to autoRange precision), and UI/UX improvements with GeomanDrawControl and native SVG tooltips. Zarr Sink improvements were implemented for minimum dimension constraints and better axis handling. Region indicator refinements with updated tests and terminology changes were completed. In parallel, critical bug fixes increased reliability for popups, issue #1804, and histogram rendering. Overall, these changes enable faster, more accurate geospatial annotations and analytics while improving data integrity and test coverage.
