Pre-release versions (1.0.0-beta.1)
^1.0.0-beta.1 means at least 1.0.0-beta.1 and below 2.0.0.
Meaning and matches
Examples
Note
A pre-release only matches a range that names a pre-release of the same version. So ^1.0.0-beta.1 allows 1.0.0-beta.2 but not 1.1.0-beta.1, which keeps unstable versions out by accident.
