3.2 How does Reach use version numbers?

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

'reach 0.1';

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.
