![2026-09-15-announcing-flower-1.37-release](https://europe1.discourse-cdn.com/flex013/uploads/flower/original/1X/6cc37a1de2e5f8754603a99322abf0b19f13adba.jpeg) The Flower team is excited to announce the release of Flower 1.37 stable, packed with new updates! **Flower is a friendly framework for collaborative AI and data science.** It makes novel approaches such as federated learning, federated evaluation, federated analytics, and fleet learning accessible to a wide audience of researchers and engineers. ### Thanks to our contributors We would like to give our special thanks to all the contributors who made the new version of Flower possible (in `git shortlog` order): `Charles Beauville`, `Chong Shen Ng`, `Daniel J. Beutel`, `Daniel Nata Nugraha`, `Dimitris Stripelis`, `Heng Pan`, `Javier`, `Julian Rußmeyer`, `Paul Thomas`, `Silvio Cretti`, `Taner Topal`, `Zhewen Tan` ### What’s new? With this release, both RuntimeAPI and ControlAPI now use HTTP, making traffic easier to inspect, debug, and integrate with standard HTTP tooling. Logging is also richer, and the default log output has changed slightly to improve readability. To see all logs, enable [verbose logging](https://flower.ai/docs/framework/1.37/en/how-to-configure-logging.html) for SuperLink, SuperNode, or SuperExec. SuperLink no longer periodically logs which SuperNodes are connected; you can query this information at any time by running `flwr supernode ls`. - **Flower CLI switches to HTTP** ([#8028](https://github.com/flwrlabs/flower/pull/8028), [#8045](https://github.com/flwrlabs/flower/pull/8045), [#8046](https://github.com/flwrlabs/flower/pull/8046), [#8047](https://github.com/flwrlabs/flower/pull/8047), [#8055](https://github.com/flwrlabs/flower/pull/8055), [#8057](https://github.com/flwrlabs/flower/pull/8057), [#8070](https://github.com/flwrlabs/flower/pull/8070), [#8072](https://github.com/flwrlabs/flower/pull/8072), [#8073](https://github.com/flwrlabs/flower/pull/8073), [#8076](https://github.com/flwrlabs/flower/pull/8076), [#8077](https://github.com/flwrlabs/flower/pull/8077), [#8084](https://github.com/flwrlabs/flower/pull/8084), [#8085](https://github.com/flwrlabs/flower/pull/8085), [#8087](https://github.com/flwrlabs/flower/pull/8087), [#8089](https://github.com/flwrlabs/flower/pull/8089), [#8093](https://github.com/flwrlabs/flower/pull/8093), [#8099](https://github.com/flwrlabs/flower/pull/8099)) - **Improve AgentApp conversations with history, connectors, titles, and local app loading** ([#8048](https://github.com/flwrlabs/flower/pull/8048), [#8058](https://github.com/flwrlabs/flower/pull/8058), [#8060](https://github.com/flwrlabs/flower/pull/8060), [#8101](https://github.com/flwrlabs/flower/pull/8101), [#8102](https://github.com/flwrlabs/flower/pull/8102), [#8104](https://github.com/flwrlabs/flower/pull/8104), [#8105](https://github.com/flwrlabs/flower/pull/8105), [#8110](https://github.com/flwrlabs/flower/pull/8110), [#8123](https://github.com/flwrlabs/flower/pull/8123), [#8127](https://github.com/flwrlabs/flower/pull/8127), [#8128](https://github.com/flwrlabs/flower/pull/8128), [#8131](https://github.com/flwrlabs/flower/pull/8131), [#8133](https://github.com/flwrlabs/flower/pull/8133), [#8148](https://github.com/flwrlabs/flower/pull/8148)) - **Configure Runtime API TLS with consistent options** ([#8109](https://github.com/flwrlabs/flower/pull/8109), [#8113](https://github.com/flwrlabs/flower/pull/8113)) - **Deploy SuperNodes using Slurm** ([#8074](https://github.com/flwrlabs/flower/pull/8074)) - **Reject invalid `FedTrimmedAvg` trimming fractions** ([#7946](https://github.com/flwrlabs/flower/pull/7946)) - **Run adaptive federated DDoS attack detection with FLAD** ([#8083](https://github.com/flwrlabs/flower/pull/8083)) - **General improvements** ([#8049](https://github.com/flwrlabs/flower/pull/8049), [#8056](https://github.com/flwrlabs/flower/pull/8056), [#8064](https://github.com/flwrlabs/flower/pull/8064), [#8066](https://github.com/flwrlabs/flower/pull/8066), [#8067](https://github.com/flwrlabs/flower/pull/8067), [#8068](https://github.com/flwrlabs/flower/pull/8068), [#8071](https://github.com/flwrlabs/flower/pull/8071), [#8075](https://github.com/flwrlabs/flower/pull/8075), [#8078](https://github.com/flwrlabs/flower/pull/8078), [#8080](https://github.com/flwrlabs/flower/pull/8080), [#8082](https://github.com/flwrlabs/flower/pull/8082), [#8088](https://github.com/flwrlabs/flower/pull/8088), [#8095](https://github.com/flwrlabs/flower/pull/8095), [#8096](https://github.com/flwrlabs/flower/pull/8096), [#8098](https://github.com/flwrlabs/flower/pull/8098), [#8103](https://github.com/flwrlabs/flower/pull/8103), [#8108](https://github.com/flwrlabs/flower/pull/8108), [#8112](https://github.com/flwrlabs/flower/pull/8112), [#8114](https://github.com/flwrlabs/flower/pull/8114), [#8115](https://github.com/flwrlabs/flower/pull/8115), [#8116](https://github.com/flwrlabs/flower/pull/8116), [#8118](https://github.com/flwrlabs/flower/pull/8118), [#8119](https://github.com/flwrlabs/flower/pull/8119), [#8120](https://github.com/flwrlabs/flower/pull/8120), [#8124](https://github.com/flwrlabs/flower/pull/8124), [#8125](https://github.com/flwrlabs/flower/pull/8125), [#8126](https://github.com/flwrlabs/flower/pull/8126), [#8129](https://github.com/flwrlabs/flower/pull/8129), [#8134](https://github.com/flwrlabs/flower/pull/8134), [#8135](https://github.com/flwrlabs/flower/pull/8135), [#8136](https://github.com/flwrlabs/flower/pull/8136), [#8137](https://github.com/flwrlabs/flower/pull/8137), [#8139](https://github.com/flwrlabs/flower/pull/8139), [#8140](https://github.com/flwrlabs/flower/pull/8140), [#8142](https://github.com/flwrlabs/flower/pull/8142), [#8144](https://github.com/flwrlabs/flower/pull/8144), [#8149](https://github.com/flwrlabs/flower/pull/8149)) ### Incompatible changes - **Remove deprecated SuperLink Exec API options** ([#8100](https://github.com/flwrlabs/flower/pull/8100)) - **Update SuperLink TLS configuration** ([#8106](https://github.com/flwrlabs/flower/pull/8106))
