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 marked as unstable and may
be changed or removed at any time. Using unstable features produces an error by
default, which can be suppressed with by passing the --unstable flag,
set unstable, or setting the environment variable JUST_UNSTABLE, to any
value other than false, 0, or the empty string.
