* Fixed: constraints in the form of `X || Y, >=Y.1` and other such complex constructs were in some cases being optimized into a more restrictive constraint
### [3.2.2] 2020-10-14
* Fixed: internal code cleanups
### [3.2.1] 2020-09-27
* Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
* Fixed: normalization of beta0 and such which was dropping the 0
### [3.2.0] 2020-09-09
* Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0
* Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience
### [3.1.0] 2020-09-08
* Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 3.0.1
* Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package
### [3.0.1] 2020-09-08
* Fixed: handling of some invalid -dev versions which were seen as valid
### [3.0.0] 2020-05-26
* Break: Renamed `EmptyConstraint`, replace it with `MatchAllConstraint`
* Break: Unlikely to affect anyone but strictly speaking a breaking change, `*.*` and such variants will not match all `dev-*` versions anymore, only `*` does
* Break: ConstraintInterface is now considered internal/private and not meant to be implemented by third parties anymore
* Added `Intervals` class to check if a constraint is a subsets of another one, and allow compacting complex MultiConstraints into simpler ones
* Added `CompilingMatcher` class to speed up constraint matching against simple Constraint instances
* Added `MatchAllConstraint` and `MatchNoneConstraint` which match everything and nothing
* Added more advanced optimization of contiguous constraints inside MultiConstraint
* Added tentative support for PHP 8
* Fixed ConstraintInterface::matches to be commutative in all cases
### [2.0.0] 2020-04-21
* Break: `dev-master`, `dev-trunk` and `dev-default` now normalize to `dev-master`, `dev-trunk` and `dev-default` instead of `9999999-dev` in 1.x
* Break: Removed the deprecated `AbstractConstraint`
* Added `getUpperBound` and `getLowerBound` to ConstraintInterface. They return `Composer\Semver\Constraint\Bound` instances
* Added `MultiConstraint::create` to create the most-optimal form of ConstraintInterface from an array of constraint strings
* Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
* Fixed: normalization of beta0 and such which was dropping the 0
### [1.7.0] 2020-09-09
* Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0
* Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience
### [1.6.0] 2020-09-08
* Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 1.5.2
* Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package
### [1.5.2] 2020-09-08
* Fixed: handling of some invalid -dev versions which were seen as valid
* Fixed: some doctypes
### [1.5.1] 2020-01-13
* Fixed: Parsing of aliased version was not validating the alias to be a valid version
### [1.5.0] 2019-03-19
* Added: some support for date versions (e.g. 201903) in `~` operator
* Fixed: support for stabilities in `~` operator was inconsistent
### [1.4.2] 2016-08-30
* Fixed: collapsing of complex constraints lead to buggy constraints
