Apache NiFi rel/nifi-2.10.0 was published on June 23, 2026 as NiFi 2.10.0, with branch creation support in Registry Clients as the clearest change for teams that manage versioned flow deployments. This is not a prerelease, and the release also groups JSON reader and writer flexibility, Content Repository cleanup, parameter context references, and cluster safety fixes into one operator focused update.

Apache NiFi is a flow based data integration platform used for ETL, streaming ingestion, and edge collection. The last week on main brought 14 commits and a large dependency refresh ahead of 2.11.0-SNAPSHOT. The work that matters for operators is not the UI package bumps. It is connector observability APIs, a Kafka header encoding fix, and several pipeline processor corrections that affect how binary metadata survives a flow.
