| title: Hydra at Facebook | |
| ### Intro | |
| Facebook has multiple different environments, such as the **Internal FB Cluster**, the **FAIR Cluster** etc. | |
| The FB specific docs are describing the differences. | |
| ### Release strategy | |
| Hydra's source of truth is the [GitHub repo](https://github.com/facebookresearch/hydra). | |
| Hydra is developed using release branches. Once a new major is released, it is maintained in patch only mode. | |
| Primary development is happening on the `master` branch. | |
| When a new major version of Hydra is released, a new release branch is created in Hydra repo. A corresponding Hydra version will be created inside `github/facebookresearch/hydra_VERSION` to track | |
| the release branch. | |
| Hydra is trying hard to remain backward compatible between two subsequent versions and in most cases the upgrade will be smooth. | |
| There could be some new deprecations warnings that should be fixed before the next major version. | |
| ### Maintaining this documentation | |
| This documentation lives in in the Hydra repo which is publicly accessible. The pages will only normally render on the internal | |
| copy of the docs, but keep in mind that everyone can read those docs in the repo if they want to. | |
| 1. Do not put anything sensitive here, no root passwords or launch codes. | |
| 2. If you are in need to have sensitive Hydra related documentation please reach out to the maintainers of Hydra for help. | |
