In 2019, while working at Facebook, I started Hydra to make it easier to build and configure complex applications. We released it as open source under the MIT license, and it grew far beyond its original setting.

Hydra became what it is because of its users, contributors, and maintainers. People adopted it in research labs, startups, large companies, and personal projects. They reported problems, proposed ideas, wrote plugins, improved the documentation, and helped shape the project over many years.

Today, I am happy to share that Hydra has moved from Meta stewardship to an independent home under the Hydra Ecosystem GitHub organization.

After many months and a lot of hard work by many people, Hydra 1.2 is released! Hydra 1.2 comes with OmegaConf 2.2, which has its own share of improvements.

We are happy to announce that we are adding a Ray Launcher to the Hydra Launchers family. Hydra's Launcher plugins enable launching to different environments without changing your existing workflows or application code. The Hydra Ray Launcher can be used to launch your application to a new or existing Ray cluster, locally or on AWS. In this post we demonstrate the major functionalities of the Launcher. For more details on installation and configuration, please check out the Hydra Ray Launcher documentation. As always, please join our community and give us feedback!

After many months and a lot of hard work by many people, Hydra 1.0 is finally out! Despite some very big changes, this is still the Hydra you love - only bigger, stronger and with more heads.
