+# ramsey/uuid Changelog
+
+## 3.8.0
+
+_Released: 2018-07-19_
+
+  * Add support for determining MAC address on FreeBSD systems ([#212](https://github.com/ramsey/uuid/pull/212))
+  * Add a polyfill for PHP ctype functions to support systems where the ctype functions are not part of the PHP build ([#223](https://github.com/ramsey/uuid/pull/223))
+  * Improve validation to disallow UUIDs with a trailing newline character ([#225](https://github.com/ramsey/uuid/pull/225))
+  * Add annotations for thrown exceptions for improved IDE hinting ([#232](https://github.com/ramsey/uuid/pull/232))
+  * Improve documentation, testing, and project metadata (i.e. `.gitattributes`, etc.)
+
+## 3.7.3
+
+_Released: 2018-01-19_
+
+  * In rare cases, when using `glob()` to find `/sys/class/net/*/address` files on Linux, `glob()` encountered errors, returning `false` instead of an empty array, causing `array_map()` to emit warnings since its second parameter was not an array; this release gracefully handles cases where `glob()` returns `false` [#203](https://github.com/ramsey/uuid/issues/203)
+  * Fixed an off-by-one error in `DefaultTimeGenerator` and switching to `random_int()` from `mt_rand()` for better random numbers [#206](https://github.com/ramsey/uuid/pull/206)
+
+## 3.7.2
+
+_Released: 2018-01-13_
+
+  * On Linux, first check sysfs to determine node identifier; this provides a reliable way to identify the node on Docker images, etc. [#185](https://github.com/ramsey/uuid/pull/185)
+
+## 3.7.1
+
+_Released: 2017-09-22_
+
+  * Use `random_bytes()` when generating random nodes
+  * Set the multicast bit for random nodes, according to RFC 4122, §4.5, [#170](https://github.com/ramsey/uuid/pull/170), [#171](https://github.com/ramsey/uuid/pull/171), [#182](https://github.com/ramsey/uuid/pull/182)
+
+## 3.7.0
+
+_Released: 2017-08-04_
+
+  * Add UUID version constants [#173](https://github.com/ramsey/uuid/issues/173), [#177](https://github.com/ramsey/uuid/pull/177)
+    * `Uuid::UUID_TYPE_TIME`
+    * `Uuid::UUID_TYPE_IDENTIFIER`
+    * `Uuid::UUID_TYPE_HASH_MD5`
+    * `Uuid::UUID_TYPE_RANDOM`
+    * `Uuid::UUID_TYPE_HASH_SHA1`
+
+## 3.6.1
+
+_Released: 2017-03-26_
+
+  * Optimize UUID string decoding [#164](https://github.com/ramsey/uuid/pull/164)
+
+## 3.6.0
+
+_Released: 2017-03-18_
+
+  * Add `InvalidUuidStringException`, thrown when attempting to decode an invalid string UUID; this does not introduce any BC issues, since the new exception inherits from the previously used `InvalidArgumentException` [#162](https://github.com/ramsey/uuid/pull/162)
+  * Improve memory usage when generating large quantities of UUIDs (use `str_pad()` and `dechex()` instead of `sprintf()`) [#160](https://github.com/ramsey/uuid/pull/160)
+  * Minor test and documentation updates
+
+## 3.5.2
+
+_Released: 2016-11-22_
+
+  * Improved test coverage.
+
+## 3.5.1

+  * Fixed issue where same UUIDs were not treated as equal with mixed case ([#131](https://github.com/ramsey/uuid/issues/131), [#137](https://github.com/ramsey/uuid/pull/137)).
+  * Test cleanup.
+
+## 3.5.0
+
+_Released: 2016-08-02_
+
+  * Add `OrderedTimeCodec` to store UUID in an optimized way for InnoDB ([#117](https://github.com/ramsey/uuid/issues/117), [#118](https://github.com/ramsey/uuid/pull/118)).
+  * Fixed `RandomNodeProvider` to prevent invalid node generation ([#129](https://github.com/ramsey/uuid/pull/129)).
+  * Cache failed attempt to retrieve system node to avoid multiple system calls ([#107](https://github.com/ramsey/uuid/issues/107), [#121](https://github.com/ramsey/uuid/pull/121)).

+
+## 3.0.0
+
+_Released: 2015-09-28_
+
+The 3.0.0 release represents a significant step for the ramsey/uuid library. While the simple and familiar API used in previous versions remains intact, this release provides greater flexibility to integrators, including the ability to inject your own number generators, UUID codecs, node and time providers, and more.
+
+  * BREAK: The root namespace for this package has changed from "Rhumsaa" to "Ramsey." In most cases, simply making this change in your applications is the only upgrade path you will need. Everything else should work as expected.
+  * BREAK: The UUID [Doctrine field type](http://doctrine-dbal.readthedocs.org/en/latest/reference/types.html) has been moved to [ramsey/uuid-doctrine](https://github.com/ramsey/uuid-doctrine).
+  * BREAK: The `uuid` console application has been moved to [ramsey/uuid-console](https://github.com/ramsey/uuid-console).
+  * BREAK: The `Uuid::VERSION` package version constant has been removed.
+  * See also the release notes for [3.0.0-alpha1][300-alpha1], [3.0.0-alpha2][300-alpha2], [3.0.0-alpha3][300-alpha3], and [3.0.0-beta1][300-beta1].

+[300-beta1]: https://github.com/ramsey/uuid/blob/master/CHANGELOG.md#300-beta1
+
+## 3.0.0-beta1
+
+_Released: 2015-08-31_
+
+  * Improve GUID support to ensure that:
+    * On little endian (LE) architectures, the byte order of the first three fields is LE.
+    * On big endian (BE) architectures, it is the same as a GUID.
+    * String representation is always the same.
+  * Fix exception message for `DegradedNumberConverter::fromHex()`.
+  * Add Scrutinizer configuration to run code-quality builds through Scrutinizer.
+  * Auto-fix Scrutinizer issues.
+  * Fix support URLs in composer.json to point to the correct GitHub repository.
+
+## 3.0.0-alpha3
+
+_Released: 2015-07-28_
+
+  * Time generator improvements:
+    * Enabled use of custom TimeGenerator implementations.
+      * BREAK: Removed now unnecessary `timeConverter` and `timeProvider` properties, setters, and getters in both `FeatureSet` and `UuidFactory` as those are now exclusively used by the default `TimeGenerator`.
+      * Added a `setTimeGenerator` method on `UuidFactory` to override the default time generator.
+    * Add option to enable `PeclUuidTimeGenerator` via `FeatureSet`.
+
+## 3.0.0-alpha2
+
+_Released: 2015-07-28_
+
+  * BREAK: Removed `PeclUuidFactory` in favor of using pecl-uuid with generators.
+  * NEW: Refactored time-based (version 1) UUIDs into a `TimeGeneratorInterface` to allow for other sources to generate version 1 UUIDs in this library.
+  * NEW: Added `PeclUuidTimeGenerator` and `PeclUuidRandomGenerator` for creating version 1 or version 4 UUIDs using the pecl-uuid extension.
+  * NEW: Add `RandomBytesGenerator` for use with PHP 7. ramsey/uuid will default to use this generator when running on PHP 7.
+  * `RandomLibAdapter` now defaults to a medium-strength generator with [ircmaxell/random-lib](https://github.com/ircmaxell/RandomLib). This is configurable, so other generator strengths may be used.
+  * Migrated to the Travis CI container-based infrastructure for builds.
+  * Documentation updates and corrections.
+
+## 3.0.0-alpha1
+
+_Released: 2015-07-16_
+
+  * BREAK: The root namespace for this package has changed from "Rhumsaa" to "Ramsey." In most cases, simply making this change in your applications is the only upgrade path you will need. Everything else should work as expected.
+  * BREAK: The UUID [Doctrine field type](http://doctrine-dbal.readthedocs.org/en/latest/reference/types.html) has been moved to [ramsey/uuid-doctrine](https://github.com/ramsey/uuid-doctrine).
+  * BREAK: The `uuid` console application has been moved to [ramsey/uuid-console](https://github.com/ramsey/uuid-console).
+  * BREAK: The `Uuid::VERSION` package version constant has been removed.
+  * NEW: The `Uuid` class is no longer marked as `final`. Everything is now based around interfaces and factories, allowing you to use this package as a base to implement other kinds of UUIDs with different dependencies.
+  * NEW: Through setting dependencies on `UuidFactory` and/or extending `FeatureSet`, you may override any package defaults, injecting your own dependencies.
+  * NEW: For random number generation, in addition to `OpenSslGenerator` (used if `openssl_random_pseudo_bytes()` is present) and the fallback `MtRandGenerator`, you may use the bundled `CombGenerator` for sequential UUIDs or the `RandomLibAdapter` if using [ircmaxell/random-lib](https://github.com/ircmaxell/RandomLib).
+  * NEW: In addition to the default UUID generation, this library also supports GUID generation by configuring a `FeatureSet` to use GUIDs.
+  * NEW: While the interface to create UUIDs hasn't changed, if using this package on a 32-bit system, you will now receive an object of type `DegradedUuid` (which extends `Uuid`, which implements `UuidInterface`).
+  * NEW: All UUIDs are now [JsonSerializable](http://php.net/JsonSerializable).
+
+## 2.9.0
+
+_Released: 2016-03-22_
+
+  * Drop support for OpenSSL in favor of [paragonie/random_compat][]. This addresses and fixes the [collision issue][].

+* Wiki: <https://github.com/ramsey/uuid/wiki>
+
+## Reporting Bugs
+
+Bugs are tracked in our project's [issue tracker](https://github.com/ramsey/uuid/issues).
+
+When submitting a bug report, please include enough information for us to reproduce the bug. A good bug report includes the following sections:
+
+* Expected outcome
+* Actual outcome
+* Steps to reproduce, including sample code
+* Any other information that will help us debug and reproduce the issue, including stack traces, system/environment information, and screenshots
+
+**Please do not include passwords or any personally identifiable information in your bug report and sample code.**
+
+## Fixing Bugs
+
+We welcome pull requests to fix bugs!
+
+If you see a bug report that you'd like to fix, please feel free to do so. Following the directions and guidelines described in the "Adding New Features" section below, you may create bugfix branches and send us pull requests.
+
+## Adding New Features
+
+If you have an idea for a new feature, it's a good idea to check out our [issues](https://github.com/ramsey/uuid/issues) or active [pull requests](https://github.com/ramsey/uuid/pulls) first to see if the feature is already being worked on. If not, feel free to submit an issue first, asking whether the feature is beneficial to the project. This will save you from doing a lot of development work only to have your feature rejected. We don't enjoy rejecting your hard work, but some features just don't fit with the goals of the project.
+
+When you do begin working on your feature, here are some guidelines to consider:
+
+* Your pull request description should clearly detail the changes you have made. We will use this description to add to our CHANGELOG. If there is no description or it does not adequately describe your feature, we will ask you to update the description.
+* We following the **[PSR-2 coding standard](http://www.php-fig.org/psr/psr-2/)**. Please ensure your code does, too.
+* Please **write tests** for any new features you add.
+* Please **ensure that tests pass** before submitting your pull request. We have Travis CI automatically running tests for pull requests. However, running the tests locally will help save time.
+* **Use topic/feature branches.** Please do not ask us to pull from your master branch.
+* **Submit one feature per pull request.** If you have multiple features you wish to submit, please break them up into separate pull requests.
+* **Send coherent history**. Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
+
+## Running Tests
+
+The following tests must pass before we will accept a pull request. If any of these do not pass, it will result in a complete build failure. Before you can run these, be sure to `composer install`.
+
+```
+composer test
+```
+
+### Locally Test With Emulated MIPS Architecture
+
+The following commands use [Vagrant](https://www.vagrantup.com/) to start an Ubuntu VM, install necessary dependencies, and then run the `tools/run-tests.sh` script that will download a Docker image emulating the MIPS architecture. This is especially helpful for testing UUID generation in a big-endian environment.
+
+```
+vagrant init ubuntu/trusty64
+vagrant up
+vagrant ssh
+sudo apt-get install docker.io qemu-user-static php5-cli php5-curl
+cd /vagrant
+curl -sS https://getcomposer.org/installer | php
+php composer.phar install --no-interaction --prefer-dist
+mkdir -p build/logs
+ARCH=mips PHP_VERSION=5.6.14 TRAVIS_BUILD_DIR=/vagrant ./tools/run-tests.sh

+_NOTICE: Formerly known as `rhumsaa/uuid`, The package and namespace names have changed to `ramsey/uuid` and `Ramsey\Uuid`, respectively._

+
+ramsey/uuid is a PHP 5.4+ library for generating and working with [RFC 4122][rfc4122] version 1, 3, 4, and 5 universally unique identifiers (UUID).
+
+This project adheres to a [Contributor Code of Conduct][conduct]. By participating in this project and its community, you are expected to uphold this code.
+
+
+## About
+
+From [Wikipedia](http://en.wikipedia.org/wiki/Universally_unique_identifier):
+
+> The intent of UUIDs is to enable distributed systems to uniquely identify information without significant central coordination. In this context the word unique should be taken to mean "practically unique" rather than "guaranteed unique". Since the identifiers have a finite size, it is possible for two differing items to share the same identifier. The identifier size and generation process need to be selected so as to make this sufficiently improbable in practice. Anyone can create a UUID and use it to identify something with reasonable confidence that the same identifier will never be unintentionally created by anyone to identify something else. Information labeled with UUIDs can therefore be later combined into a single database without needing to resolve identifier (ID) conflicts.
+
+Much inspiration for this library came from the [Java][javauuid] and [Python][pyuuid] UUID libraries.
+
+
+## Installation
+
+The preferred method of installation is via [Packagist][] and [Composer][]. Run the following command to install the package and add it as a requirement to your project's `composer.json`:
+
+```bash
+composer require ramsey/uuid
+```
+
+
+## Upgrading from 2.x to 3.x
+
+While we have made significant internal changes to the library, we have made every effort to ensure a seamless upgrade path from the 2.x series of this library to 3.x.
+
+One major breaking change is the transition from the `Rhumsaa` root namespace to `Ramsey`. In most cases, all you will need is to change the namespace to `Ramsey` in your code, and everything will "just work."
+
+Here are full details on the breaking changes to the public API of this library:
+
+1. All namespace references of `Rhumsaa` have changed to `Ramsey`. Simply change the namespace to `Ramsey` in your code and everything should work.
+2. The console application has moved to [ramsey/uuid-console](https://packagist.org/packages/ramsey/uuid-console). If using the console functionality, use Composer to require `ramsey/uuid-console`.
+3. The Doctrine field type mapping has moved to [ramsey/uuid-doctrine](https://packagist.org/packages/ramsey/uuid-doctrine). If using the Doctrine functionality, use Composer to require `ramsey/uuid-doctrine`.
+
+
+## What to do if you see a "rhumsaa/uuid is abandoned" message
+
+When installing your project's dependencies using Composer, you might see the following message:
+
+```
+Package rhumsaa/uuid is abandoned, you should avoid using it. Use ramsey/uuid instead.
+```
+
+Don't panic. Simply execute the following commands with Composer:
+
+``` bash
+composer remove rhumsaa/uuid
+composer require ramsey/uuid=^2.9
+```
+
+After doing so, you will have the latest ramsey/uuid package in the 2.x series, and there will be no need to modify any code; the namespace in the 2.x series is still `Rhumsaa`.
+
+
+## Requirements
+
+Some methods in this library have requirements due to integer size restrictions on 32-bit and 64-bit builds of PHP. A 64-bit build of PHP and the [Moontoast\Math][] library are recommended. However, this library is designed to work on 32-bit builds of PHP without Moontoast\Math, with some degraded functionality. Please check the API documentation for more information.
+
+If a particular requirement is not present, then an `UnsatisfiedDependencyException` is thrown, allowing one to catch a bad call in an environment where the call is not supported and gracefully degrade.
+
+
+## API documentation
+
+The [latest class API documentation][apidocs] is available online.
+
+This project uses [ApiGen](http://apigen.org/) to generate this documentation. To generate the documentation on your own, install dev dependencies and run the following command from the root of the project:
+
+```
+composer build-docs
+```
+
+This will generate documentation in the `build/apidocs/` folder.
+
+
+## Examples
+
+See the [cookbook on the wiki][wiki-cookbook] for more examples and approaches to specific use-cases.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use Ramsey\Uuid\Uuid;
+use Ramsey\Uuid\Exception\UnsatisfiedDependencyException;
+
+try {
+
+    // Generate a version 1 (time-based) UUID object
+    $uuid1 = Uuid::uuid1();
+    echo $uuid1->toString() . "\n"; // i.e. e4eaaaf2-d142-11e1-b3e4-080027620cdd
+
+    // Generate a version 3 (name-based and hashed with MD5) UUID object
+    $uuid3 = Uuid::uuid3(Uuid::NAMESPACE_DNS, 'php.net');
+    echo $uuid3->toString() . "\n"; // i.e. 11a38b9a-b3da-360f-9353-a5a725514269
+
+    // Generate a version 4 (random) UUID object
+    $uuid4 = Uuid::uuid4();
+    echo $uuid4->toString() . "\n"; // i.e. 25769c6c-d34d-4bfe-ba98-e0ee856f3e7a
+
+    // Generate a version 5 (name-based and hashed with SHA1) UUID object
+    $uuid5 = Uuid::uuid5(Uuid::NAMESPACE_DNS, 'php.net');
+    echo $uuid5->toString() . "\n"; // i.e. c4a760a8-dbcf-5254-a0d9-6a4474bd1b62
+
+} catch (UnsatisfiedDependencyException $e) {
+
+    // Some dependency was not met. Either the method cannot be called on a
+    // 32-bit system, or it can, but it relies on Moontoast\Math to be present.
+    echo 'Caught exception: ' . $e->getMessage() . "\n";
+
+}
+```
