Backwards Compatibility
With the release of version 1.0, just features a strong commitment to backwards compatibility and stability.
Future releases will not introduce backwards incompatible changes that make existing justfiles stop working, or break working invocations of the command-line interface.
This does not, however, preclude fixing outright bugs, even if doing so might break justfiles that rely on their behavior.
There will never be a just 2.0. Any desirable backwards-incompatible changes will be opt-in on a per-justfile basis, so users may migrate at their leisure.
Features that aren’t yet ready for stabilization are gated behind the --unstable flag. Features enabled by --unstable may change in backwards incompatible ways at any time.
