Even though newer versions may have been released since 2021, many enterprises and hobbyists stick with the 2021 build for three reasons:

| Event / Release | Date (2021) | Why It Matters | |-----------------|-------------|----------------| | DF6‑Flow v1.0 | March 15 | First stable, production‑ready version; introduced pipeline as code concept and YAML‑based definitions. | | df6org Global Summit | June 9‑10 (virtual) | 500+ participants; keynote by Dr. Ada Liu (MIT) on “Composable AI pipelines”. Recordings now on YouTube (CC‑BY). | | DF6‑Hub Component Registry | July 22 | 1 200+ community‑contributed components (connectors for Kafka, S3, PostgreSQL, etc.). | | DF6‑Bench v2 | September 3 | Added GPU‑accelerated benchmarks; became reference for ML‑pipeline performance. | | First Annual “Open‑Data‑Flow Challenge” | October 14‑31 | Hackathon where teams built end‑to‑end pipelines on a shared dataset; winner received a $10 k grant for further development. | | Launch of “df6.org” website redesign | November 12 | Central hub for documentation, community forum, and live status dashboards. | | Funding Round | December 2 | Secured $500 k from the Open Technology Fund, enabling full‑time staff for core engineering. |

These highlights illustrate how 2021 moved df6org from a prototype community to a recognized open‑source platform.

A common thread across technical support boards is the search for "df6org 2021 driver." Some older Canon, Epson, or Brother multifunction printers used driver package names containing "df6." A 2021 release would likely include compatibility fixes for Windows 10 or macOS Big Sur.
