In March 2026, delivered key enhancements to romancal's multiband association workflow, improving reliability and usability for cross-skycell data ingestion. The main feature upgraded file-name parsing to handle both positive and negative declinations, added skycell-based grouping, expanded supported file formats, and strengthened test coverage. A bug fix addresses parsing issues for positive declinations, ensuring consistent association results across formats (commit 83f5493bb2168ed516805218d87092e4c24cc996). These changes reduce data-ingestion errors, simplify pipelines, and enable scalable analysis of large surveys.

February 2026 (2026-02) monthly summary for spacetelescope/romancal focused on advancing standardized data products and improving processing accuracy for the Roman mission.

December 2025 (romancal) monthly summary focusing on delivered capabilities and bug fixes that improve data processing workflows and user usability. Key outcomes include a new multiband data management class and documentation improvements that reduce onboarding time and support effort.

November 2025 performance snapshot for spacetelescope/romancal focusing on data release metadata enhancements and data association grouping. Delivered a cohesive feature set that improves data provenance, traceability, and release management across multi-visit datasets, with minimal disruption to existing workflows.

September 2025 monthly summary: Delivered targeted improvements across the JWST and Romancal repositories, focusing on reliability, build stability, and extended weighting capabilities for resampling workflows. The month emphasized robust test coverage, safer dependency management, and new weighting options to support higher-fidelity data processing.

April 2025 monthly summary for spacetelescope/jwst focused on enabling and accelerating sky_var_rdnoise development via fork-based dependency management. Key actions included configuring the build to depend on a forked stcal branch and pointing stcal to a temporary fork repository to facilitate isolated testing and faster iteration.

November 2024 performance summary for spacetelescope/romancal: centralization of S_REGION keyword generation using a shared utility, simplification of test formats, and a bug fix in ResampleData. These changes improve consistency of metadata, reduce maintenance burden, and enhance data provenance and test reliability. Key commits include 11364dd337200b7a8400cc230103a414d6548fe8, c068147d50e8a9118c5b7478dcad5173e0fb8cc4, c5dd2ddc8c5d1c4aeb98faff9430da213045ce9b, and 088212b1e46361447e86954f35a44569b0c2bd30.

October 2024: Delivered a critical enhancement to TweakRegStep in romancal to keep s_region metadata synchronized after WCS adjustments, ensuring spatial regions remain correct after astrometric corrections. Implemented the metadata update, added a targeted test, and extended get_catalog_data to support additional keyword arguments. Included a changelog entry to document the change. These changes improve downstream region handling, data integrity, and traceability for future analyses.
