Aug 1, 2025Month 2025-08 recap for fusedio/udfs: Focused on stabilizing logging and clarifying observability in crop index mapping. Implemented a targeted bug fix to suppress verbose cache logging by forcing cache_verbose to False in the int_to_crop call within crop_stats, reducing log noise and potential performance impact. This change preserves functional behavior of crop mapping while improving log quality and observability. Evidence of work is captured in commit 6b612aa7252a03ad3bb45c5c3fac40b88e98e624 ("remove cache msg (#1183)").

Mar 1, 2025March 2025 delivered a focused geospatial and data tooling upgrade for fusedio/udfs, with an emphasis on reliability, performance, and developer productivity. Key features delivered include robust geospatial tile handling (estimate_zoom fix, added get_tile) and numpy-friendly geo_convert, plus DataFrame analytics utilities (df_summary). The release also expanded coordinate tooling with UTM EPSG/area helpers (get_utm_epsg, get_utm_area) and advanced batch processing/UDF workflows (submit_batch, func_to_udf, Batch_Job support) along with caching controls for udf and submit_job. Additional improvements to developer tooling and data utilities—diff text generation (get_diff_text), only_diff option, and serialization enhancements (pickle-based, with encode/decode utilities and tests)—further boost reliability and speed of feature delivery. Overall impact: accelerated feature delivery for geospatial data pipelines, improved data observability, and scalable batch processing, underpinned by stronger testing and targeted bug fixes.
