+# Changelog
+
+All notable changes to phar-io/version are documented in this file using the [Keep a CHANGELOG](http://keepachangelog.com/) principles.
+
+## [2.0.1] - 08.07.2018
+
+### Fixed
+
+- Versions without a pre-release suffix are now always considered greater 
+than versions without 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.  
+
+[2.0.1]: https://github.com/phar-io/version/compare/2.0.0...2.0.1
+[2.0.0]: https://github.com/phar-io/version/compare/1.0.1...2.0.0

+# 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
+
+```
