Using ~ with a minor version specified allows patch changes. Using ~ with only major version specified will allow minor changes.
| Version range | Expanded version range |
|---|---|
~3.1.4 | >=3.1.4 <3.2.0 |
~3.1 | 3.1.xor>=3.1.0 <3.2.0 |
~3 | 3.xor>=3.0.0 <4.0.0 |
Note: Specifying pre-releases in tilde ranges will only match pre-releases in that same full version. For example, the version range ~3.1.4-beta.2 would match against 3.1.4-beta.4 but not 3.1.5-beta.2 because the major.minor.patch version is different.
Allow changes that do not modify the first non-zero digit in the version, either the 3 in 3.1.4 or the 4 in 0.4.2.
