Reach uses semantic versioning, which means that given Reach version number MAJOR.MINOR.PATCH,
MAJOR versions are incompatible.
MINOR versions are compatible, but have additional features relative to earlier version.
PATCH versions are entirely compatible.
However, the major version 0.y.z is pre-stability and makes no promises about compatibility of any kind.
Reach source code starts with
because this indicates that it relies on this major version and the features added in this minor version.
Reach tools are specified by the entire version number with a v at the front, vMAJOR.MINOR.PATCH, but are also available at all prefixes (i.e., vMAJOR.MINOR and vMAJOR). Additionally, there is a version stable which resolves to the most recent stable vMAJOR version.
