February 2026 (2026-02) monthly summary for apache/nifi development. Focused on security and protocol compliance improvements in the HTTP Replication Client. Key delivery: RFC 9112-compliant handling by disallowing the Transfer-Encoding header in replicated HTTP requests, with automated tests to verify enforcement during replication. This change reduces cross-node replication risks, enforces consistent behavior across environments, and strengthens security posture for HTTP replication.

December 2025 focused on reliability improvements and deployment flexibility for Apache NiFi. Delivered a critical bug fix for streaming failures in ExecuteSQLRecord and introduced Kerberos configuration support for NiFi Registry, enabling non-standard krb5.conf paths. These changes enhance error handling, observability, and secure deployment options with minimal operational disruption.

December 2024 — Apache NiFi (apache/nifi): Stability and test coverage improvements for Python processors. Delivered a reliability improvement by correcting the Python Processor Description Display, ensuring extension tags are properly set in definitions, and updated regression tests for manifest-related metadata. No new user-facing features this month; focus was on improving accuracy, reliability, and maintainability of processor metadata across the UI and management plane.
