Jun 1, 2025June 2025 summary for Apache NiFi (apache/nifi): Delivered a critical correctness improvement for the ReplaceByPattern feature by enabling handling of duplicate replacement values. This was achieved via a refactor of internal storage from a Map to a List of PatternMapping objects, which allows multiple patterns to map to the same replacement value without loss of accuracy. Added tests to verify correct behavior and prevent regressions. The changes focus on reliability and data integrity in pattern-based replacements across NiFi data flows.
