pub_semver 2.0.0

Versions and version constraints implementing pub's versioning policy. This is very similar to vanilla semver, with a few corner cases.

2.0.0

• Stable null safety release.

2.0.0-nullsafety.0

• Migrate to null safety.
• Version.primary now throws StateError if the versions argument is empty.

1.4.4

• Fix a bug of VersionRange.union where ranges bounded at infinity would get combined wrongly.

1.4.3

• Update Dart SDK constraint to >=2.0.0 <3.0.0.
• Update package:collection constraint to ^1.0.0.

1.4.2

• Set max SDK version to <3.0.0.

1.4.1

• Fix a bug where there upper bound of a version range with a build identifier could accidentally be rewritten.

1.4.0

• Add a Version.firstPreRelease getter that returns the first possible pre-release of a version.

• Add a Version.isFirstPreRelease getter that returns whether a version is the first possible pre-release.

• new VersionRange() with an exclusive maximum now replaces the maximum with its first pre-release version. This matches the existing semantics, where an exclusive maximum would exclude pre-release versions of that maximum.

  Explicitly representing this by changing the maximum version ensures that all operations behave correctly with respect to the special pre-release semantics. In particular, it fixes bugs where, for example, (>=1.0.0 <2.0.0-dev).union(>=2.0.0-dev <2.0.0) and (>=1.0.0 <3.0.0).difference(^1.0.0) wouldn't include 2.0.0-dev.

• Add an alwaysIncludeMaxPreRelease parameter to new VersionRange(), which disables the replacement described above and allows users to create ranges that do include the pre-release versions of an exclusive max version.

1.3.7

• Fix more bugs with VersionRange.intersect(), VersionRange.difference(), and VersionRange.union() involving version ranges with pre-release maximums.

1.3.6

• Fix a bug where constraints that only allowed pre-release versions would be parsed as empty constraints.

1.3.5

• Fix a bug where VersionRange.intersect() would return incorrect results for pre-release versions with the same base version number as release versions.

1.3.4

• Fix a bug where VersionRange.allowsAll(), VersionRange.allowsAny(), and VersionRange.difference() would return incorrect results for pre-release versions with the same base version number as release versions.

1.3.3

• Fix a bug where VersionRange.difference() with a union constraint that covered the entire range would crash.

1.3.2

• Fix a checked-mode error in VersionRange.difference().

1.3.1

• Fix a new strong mode error.

1.3.0

• Make the VersionUnion class public. This was previously used internally to implement new VersionConstraint.unionOf() and VersionConstraint.union(). Now it's public so you can use it too.

• Added VersionConstraint.difference(). This returns a constraint matching all versions matched by one constraint but not another.

• Make VersionRange implement Comparable<VersionRange>. Ranges are ordered first by lower bound, then by upper bound.

1.2.4

• Fix all remaining strong mode warnings.

1.2.3

• Addressed three strong mode warnings.

1.2.2

• Make the package analyze under strong mode and compile with the DDC (Dart Dev Compiler). Fix two issues with a private subclass of VersionConstraint having different types for overridden methods.

1.2.1

• Allow version ranges like >=1.2.3-dev.1 <1.2.3 to match pre-release versions of 1.2.3. Previously, these didn't match, since the pre-release versions had the same major, minor, and patch numbers as the max; now an exception has been added if they also have the same major, minor, and patch numbers as the min and the min is also a pre-release version.

1.2.0

• Add a VersionConstraint.union() method and a new VersionConstraint.unionOf() constructor. These each return a constraint that matches multiple existing constraints.

• Add a VersionConstraint.allowsAll() method, which returns whether one constraint is a superset of another.

• Add a VersionConstraint.allowsAny() method, which returns whether one constraint overlaps another.

• Version now implements VersionRange.

1.1.0

• Add support for the ^ operator for compatible versions according to pub's notion of compatibility. ^1.2.3 is equivalent to >=1.2.3 <2.0.0; ^0.1.2 is equivalent to >=0.1.2 <0.2.0.

• Add Version.nextBreaking, which returns the next version that introduces breaking changes after a given version.

• Add new VersionConstraint.compatibleWith(), which returns a range covering all versions compatible with a given version.

• Add a custom VersionRange.hashCode to make it properly hashable.

1.0.0

• Initial release.
