Aug 1, 2025Month: 2025-08 - Focused on a targeted bug fix in porepy to improve deprecation warning accuracy during export flows, delivering business value by reducing noise and clarifying deprecated functionality usage. Key improvement: deprecation warnings are now issued only when the deprecated functionality is invoked, instead of at the start of Exporter methods. This change enhances user experience and maintains backward compatibility while simplifying debugging of export workflows.

Jan 1, 2025January 2025 — Focused on improving data integrity in the grid refinement workflow for fracture data within porepy. Implemented a critical bug fix to preserve fracture numbers during grid refinement by extracting the fracture number before refinement and reassigning it to the newly refined grid, preventing data loss and incorrect associations. The change includes tests to validate the preservation behavior (commit: b567d8c342afbccdaff6e07e304c10369daebcff; message: TST: Preserve fracture number during grid refinement process).
