Sep 1, 2025September 2025 for gwastro/pycbc: Key features delivered included (1) Flexible HDF Bank Splitter Configuration, enabling users to specify either the number of output banks or the approximate number of templates per bank with refined input validation and more robust distribution logic; (2) Enhanced PyGRB Injection Visualization, refactoring the found-missed plot to support calculating and plotting effective distances, with updated axis labels and captions and improved plotting for diverse injection scenarios; (3) PyGRB Workflow Dependency Synchronization bug fix, ensuring results_page generation waits for minifollowup tasks and removing unused variables / an unnecessary else block for code cleanliness. Major bugs fixed: the PyGRB workflow dependency issue now reliably coordinates subworkflows and results_page jobs, reducing flaky results. Overall impact and accomplishments: increased reliability and throughput of the PyGRB workflow, clearer and more informative visualizations for assessment, and greater configuration flexibility reducing manual intervention. Technologies/skills demonstrated: Python refactoring and cleanup, input validation hardening, data visualization enhancements, and cross-module dependency management; clear traceability to commits 2bef4f07bf12b29236a9e49bd3e3950b1d0999c0, 8fc4f9548483acd3c2e64eb233ea91e3b95edc70, and cc1c8d60342d95992ad8b408e74bba29d72d7880.
