Caret ranges are ideal when an author may make breaking changes | |
between `0.2.4` and `0.3.0` releases, which is a common practice. | |
However, it presumes that there will *not* be breaking changes between | |
`0.2.4` and `0.2.5`. It allows for changes that are presumed to be | |
additive (but non-breaking), according to commonly observed practices. | |
* `^1.2.3` := `>=1.2.3 <2.0.0` | |
* `^0.2.3` := `>=0.2.3 <0.3.0` | |
* `^0.0.3` := `>=0.0.3 <0.0.4` | |
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in | |
the `1.2.3` version will be allowed, if they are greater than or | |
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but | |
`1.2.4-beta.2` would not, because it is a prerelease of a | |
different `[major, minor, patch]` tuple. | |
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4` Note that prereleases in the | |
`0.0.3` version *only* will be allowed, if they are greater than or | |
equal to `beta`. So, `0.0.3-pr.2` would be allowed. | |
When parsing caret ranges, a missing `patch` value desugars to the | |
number `0`, but will allow flexibility within that value, even if the | |
major and minor versions are both `0`. | |
* `^1.2.x` := `>=1.2.0 <2.0.0` | |
* `^0.0.x` := `>=0.0.0 <0.1.0` | |
* `^0.0` := `>=0.0.0 <0.1.0` | |
A missing `minor` and `patch` values will desugar to zero, but also | |
allow flexibility within those values, even if the major version is | |
zero. | |
* `^1.x` := `>=1.0.0 <2.0.0` | |
* `^0.x` := `>=0.0.0 <1.0.0` |

#### Tilde Ranges `~1.2.3` `~1.2` `~1` | |
Allows patch-level changes if a minor version is specified on the | |
comparator. Allows minor-level changes if not. | |
