+# Changelog
+
+All notable changes to phar-io/version are documented in this file using the [Keep a CHANGELOG](http://keepachangelog.com/) principles.
+
+## [3.2.1] - 2022-02-21
+
+### Fixed
+
+- Have ExactVersionConstraint honor build metadata (added in 3.2.0)
+
+
+## [3.2.0] - 2022-02-21
+
+### Added
+
+- Build metadata is now supported and considered for equality checks only
+
+
+## [3.1.1] - 2022-02-07
+
+### Fixed
+
+- [#28](https://github.com/phar-io/version/issues/28): `VersionConstraintParser` does not support logical OR represented by single pipe (|) (Thanks @llaville)
+
+
+## [3.1.0] - 2021-02-23
+
+### Changed
+
+- Internal Refactoring
+- More scalar types
+
+### Added
+
+- [#24](https://github.com/phar-io/version/issues/24): `Version::getOriginalString()` added (Thanks @addshore)
+- Version constraints using the caret operator (`^`) now honor pre-1.0 releases, e.g. `^0.3` translates to `0.3.*`)
+- Various integration tests for version constraint processing
+
+### Fixed
+
+- [#23](https://github.com/phar-io/version/pull/23): Tilde operator without patch level
+
+
+
+## [3.0.4] - 14.12.2020
+
+### Fixed 
+
+- [#22](https://github.com/phar-io/version/pull/22): make dev suffix rank works for uppercase too
+
+## [3.0.3] - 30.11.2020
+
+### Added
+
+- Comparator method `Version::equals()` added
+
+
+## [3.0.2] - 27.06.2020
+
+This release now supports PHP 7.2+ and PHP ^8.0. No other changes included.
+
+
+## [3.0.1] - 09.05.2020
+
+__Potential BC Break Notice:__
+`Version::getVersionString()` no longer returns `v` prefixes in case the "input"
+string contained one. These are not part of the semver specs
+(see https://semver.org/#is-v123-a-semantic-version) and get stripped out.
+As of Version 3.1.0 `Version::getOriginalString()` can be used to still
+retrieve it as given.
+
+### Changed
+
+- Internal Refactoring
+- More scalar types
+
+### Fixed
+
+- Fixed Constraint processing Regression for ^1.2  and ~1.2
+
+
+## [3.0.0] - 05.05.2020
+
+### Changed
+
+- Require PHP 7.2+
+- All code now uses strict mode
+- Scalar types have been added as needed
+
+### Added
+
+- The technically invalid format using 'v' prefix ("v1.2.3") is now properly supported 
+
+
+## [2.0.1] - 08.07.2018
+
+### Fixed
+
+- Versions without a pre-release suffix are now always considered greater 
+than versions with a pre-release suffix. Example: `3.0.0 > 3.0.0-alpha.1`  
+
+
+## [2.0.0] - 23.06.2018
+
+Changes to public API:
+
+- `PreReleaseSuffix::construct()`: optional parameter `$number` removed
+- `PreReleaseSuffix::isGreaterThan()`: introduced
+- `Version::hasPreReleaseSuffix()`: introduced
+
+### Added
+
+- [#11](https://github.com/phar-io/version/issues/11): Added support for pre-release version suffixes. Supported values are:
+  - `dev`
+  - `beta` (also abbreviated form `b`)
+  - `rc`
+  - `alpha` (also abbreviated form `a`)
+  - `patch` (also abbreviated form `p`)
+
+  All values can be followed by a number, e.g. `beta3`. 
+
+  When comparing versions, the pre-release suffix is taken into account. Example:
+`1.5.0 > 1.5.0-beta1 > 1.5.0-alpha3 > 1.5.0-alpha2 > 1.5.0-dev11`
+
+### Changed
+
+- reorganized the source directories
+
+### Fixed
+
+- [#10](https://github.com/phar-io/version/issues/10): Version numbers containing 
+a numeric suffix as seen in Debian packages are now supported.

+# Version
+
+Library for handling version information and constraints
+
+[![Build Status](https://travis-ci.org/phar-io/version.svg?branch=master)](https://travis-ci.org/phar-io/version)
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phar-io/version
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phar-io/version
+
+## Version constraints
+
+A Version constraint describes a range of versions or a discrete version number. The format of version numbers follows the schema of [semantic versioning](http://semver.org): `<major>.<minor>.<patch>`. A constraint might contain an operator that describes the range.
+
+Beside the typical mathematical operators like `<=`, `>=`, there are two special operators:
+
+*Caret operator*: `^1.0`
+can be written as `>=1.0.0 <2.0.0` and read as »every Version within major version `1`«.
+
+*Tilde operator*: `~1.0.0`
+can be written as `>=1.0.0 <1.1.0` and read as »every version within minor version `1.1`. The behavior of tilde operator depends on whether a patch level version is provided or not. If no patch level is provided, tilde operator behaves like the caret operator: `~1.0` is identical to `^1.0`.
+
+## Usage examples
+
+Parsing version constraints and check discrete versions for compliance:
+
+```php
+
+use PharIo\Version\Version;
+use PharIo\Version\VersionConstraintParser;
+
+$parser = new VersionConstraintParser();
+$caret_constraint = $parser->parse( '^7.0' );
+
+$caret_constraint->complies( new Version( '7.0.17' ) ); // true
+$caret_constraint->complies( new Version( '7.1.0' ) ); // true
+$caret_constraint->complies( new Version( '6.4.34' ) ); // false
+
+$tilde_constraint = $parser->parse( '~1.1.0' );
+
+$tilde_constraint->complies( new Version( '1.1.4' ) ); // true
+$tilde_constraint->complies( new Version( '1.2.0' ) ); // false
+```
+
+As of version 2.0.0, pre-release labels are supported and taken into account when comparing versions:
+
+```php
+
+$leftVersion = new PharIo\Version\Version('3.0.0-alpha.1');
+$rightVersion = new PharIo\Version\Version('3.0.0-alpha.2');
+
+$leftVersion->isGreaterThan($rightVersion); // false
+$rightVersion->isGreaterThan($leftVersion); // true
+
+```
