+CHANGELOG
+=========
+
+1.10.1 (2021-04-14)
+-------------------
+
+* Fix a `TypeError` exception in the pure PHP reader when using large
+ databases on 32-bit PHP builds with the `bcmath` extension. Reported
+ by dodo1708. GitHub #124.
+
+1.10.0 (2021-02-09)
+-------------------
+
+* When using the pure PHP reader, unsigned integers up to PHP_MAX_INT
+ will now be integers in PHP rather than strings. Previously integers
+ greater than 2^24 on 32-bit platforms and 2^56 on 64-bit platforms
+ would be strings due to the use of `gmp` or `bcmath` to decode them.
+ Reported by Alejandro Celaya. GitHub #119.
+
+1.9.0 (2021-01-07)
+------------------
+
+* The `maxminddb` extension is now buildable on Windows. Pull request
+ by Jan Ehrhardt. GitHub #115.
+
+1.8.0 (2020-10-01)
+------------------
+
+* Fixes for PHP 8.0. Pull Request by Remi Collet. GitHub #108.
+
+1.7.0 (2020-08-07)
+------------------
+
+* IMPORTANT: PHP 7.2 or greater is now required.
+* The extension no longer depends on the pure PHP classes in
+ `maxmind-db/reader`. You can use it independently.
+* Type hints have been added to both the pure PHP implementation
+ and the extension.
+* The `metadata` method on the reader now returns a new copy of the
+ metadata object rather than the actual object used by the reader.
+* Work around PHP `is_readable()` bug. Reported by Ben Roberts. GitHub
+ #92.
+* This is the first release of the extension as a PECL package.
+ GitHub #34.
+
+1.6.0 (2019-12-19)
+------------------
+
+* 1.5.0 and 1.5.1 contained a possible memory corruptions when using
+ `getWithPrefixLen`. This has been fixed. Reported by proton-ab.
+ GitHub #96.
+* The `composer.json` file now conflicts with all versions of the
+ `maxminddb` C extension less than the Composer version. This is to
+ reduce the chance of having an older, conflicting version of the
+ extension installed. You will need to upgrade the extension before
+ running `composer update`. Pull request by Benoît Burnichon. GitHub
+ #97.
+
+1.5.1 (2019-12-12)
+------------------
+
+* Minor performance improvements.
+* Make tests pass with older versions of libmaxminddb. PR by Remi
+ Collet. GitHub #90.
+* Test enhancements. PR by Chun-Sheng, Li. GitHub #91.
+
+1.5.0 (2019-09-30)
+------------------
+
+* PHP 5.6 or greater is now required.
+* The C extension now supports PHP 8. Pull request by John Boehr.
+ GitHub #87.
+* A new method, `getWithPrefixLen`, was added to the `Reader` class.
+ This method returns an array containing the record and the prefix
+ length for that record. GitHub #89.
+
+1.4.1 (2019-01-04)
+------------------
+
+* The `maxminddb` extension now returns a string when a `uint32`
+ value is greater than `LONG_MAX`. Previously, the value would
+ overflow. This generally only affects 32-bit machines. Reported
+ by Remi Collet. GitHub #79.
+* For `uint64` values, the `maxminddb` extension now returns an
+ integer rather than a string when the value is less than or equal
+ to `LONG_MAX`. This more closely matches the behavior of the pure
+ PHP reader.
+
+1.4.0 (2018-11-20)
+------------------
+
+* The `maxminddb` extension now has the arginfo when using reflection.
+ PR by Remi Collet. GitHub #75.
+* The `maxminddb` extension now provides `MINFO()` function that
+ displays the extension version and the libmaxminddb version. PR by
+ Remi Collet. GitHub #74.
+* The `maxminddb` `configure` script now uses `pkg-config` when
+ available to get libmaxmindb build info. PR by Remi Collet.
+ GitHub #73.
+* The pure PHP reader now correctly decodes integers on 32-bit platforms.
+ Previously, large integers would overflow. Reported by Remi Collet.
+ GitHub #77.
+* There are small performance improvements for the pure PHP reader.
+
+1.3.0 (2018-02-21)
+------------------
+
+* IMPORTANT: The `maxminddb` extension now obeys `open_basedir`. If
+ `open_basedir` is set, you _must_ store the database within the
+ specified directory. Placing the file outside of this directory
+ will result in an exception. Please test your integration before
+ upgrading the extension. This does not affect the pure PHP
+ implementation, which has always had this restriction. Reported
+ by Benoît Burnichon. GitHub #61.
+* A custom `autoload.php` file is provided for installations without
+ Composer. GitHub #56.
+
+1.2.0 (2017-10-27)
+------------------
+
+* PHP 5.4 or greater is now required.
+* The `Reader` class for the `maxminddb` extension is no longer final.
+ This was change to match the behavior of the pure PHP class.
+ Reported and fixed by venyii. GitHub #52 & #54.
+
+1.1.3 (2017-01-19)
+------------------
+
+* Fix incorrect version in `ext/php_maxminddb.h`. GitHub #48.
+
+1.1.2 (2016-11-22)
+------------------
+
+* Searching for database metadata only occurs within the last 128KB
+ (128 * 1024 bytes) of the file, speeding detection of corrupt
+ datafiles. Reported by Eric Teubert. GitHub #42.
+* Suggest relevant extensions when installing with Composer. GitHub #37.
+
+1.1.1 (2016-09-15)
+------------------
+
+* Development files were added to the `.gitattributes` as `export-ignore` so
+ that they are not part of the Composer release. Pull request by Michele
+ Locati. GitHub #39.
+
+1.1.0 (2016-01-04)
+------------------
+
+* The MaxMind DB extension now supports PHP 7. Pull request by John Boehr.
+ GitHub #27.
+
+1.0.3 (2015-03-13)
+------------------
+
+* All uses of `strlen` were removed. This should prevent issues in situations
+ where the function is overloaded or otherwise broken.
+
+1.0.2 (2015-01-19)
+------------------
+
+* Previously the MaxMind DB extension would cause a segfault if the Reader
+ object's destructor was called without first having called the constructor.
+ (Reported by Matthias Saou & Juan Peri. GitHub #20.)
+
+1.0.1 (2015-01-12)
+------------------
+
+* In the last several releases, the version number in the extension was
+ incorrect. This release is being done to correct it. No other code changes
+ are included.
+
+1.0.0 (2014-09-22)
+------------------
+
+* First production release.
+* In the pure PHP reader, a string length test after `fread()` was replaced
+ with the difference between the start pointer and the end pointer. This
+ provided a 15% speed increase.
+
+0.3.3 (2014-09-15)
+------------------
+
+* Clarified behavior of 128-bit type in documentation.
+* Updated phpunit and fixed some test breakage from the newer version.
+
+0.3.2 (2014-09-10)
+------------------
+
+* Fixed invalid reference to global class RuntimeException from namespaced
+ code. Fixed by Steven Don. GitHub issue #15.
+* Additional documentation of `Metadata` class as well as misc. documentation
+ cleanup.
+
+0.3.1 (2014-05-01)
+------------------
+
+* The API now works when `mbstring.func_overload` is set.
+* BCMath is no longer required. If the decoder encounters a big integer,
+ it will try to use GMP and then BCMath. If both of those fail, it will
+ throw an exception. No databases released by MaxMind currently use big
+ integers.
+* The API now officially supports HHVM when using the pure PHP reader.
+
+0.3.0 (2014-02-19)
+------------------
+
+* This API is now licensed under the Apache License, Version 2.0.
+* The code for the C extension was cleaned up, fixing several potential
+ issues.
+
+0.2.0 (2013-10-21)
+------------------
+
+* Added optional C extension for using libmaxminddb in place of the pure PHP
+ reader.
+* Significantly improved error handling in pure PHP reader.
+* Improved performance for IPv4 lookups in an IPv6 database.
+
+0.1.0 (2013-07-16)
+------------------
+
+* Initial release

+# MaxMind DB Reader PHP API #
+
+## Description ##
+
+This is the PHP API for reading MaxMind DB files. MaxMind DB is a binary file
+format that stores data indexed by IP address subnets (IPv4 or IPv6).
+
+## Installation (Composer) ##
+
+We recommend installing this package with [Composer](https://getcomposer.org/).
+
+### Download Composer ###
+
+To download Composer, run in the root directory of your project:
+
+```bash
+curl -sS https://getcomposer.org/installer | php
+```
+
+You should now have the file `composer.phar` in your project directory.
+
+### Install Dependencies ###
+
+Run in your project root:
+
+```
+php composer.phar require maxmind-db/reader:~1.0
+```
+
+You should now have the files `composer.json` and `composer.lock` as well as
+the directory `vendor` in your project directory. If you use a version control
+system, `composer.json` should be added to it.
+
+### Require Autoloader ###
+
+After installing the dependencies, you need to require the Composer autoloader
+from your code:
+
+```php
+require 'vendor/autoload.php';
+```
+
+## Installation (Standalone) ##
+
+If you don't want to use Composer for some reason, a custom
+`autoload.php` is provided for you in the project root. To use the
+library, simply include that file,
+
+```php
+require('/path/to/MaxMind-DB-Reader-php/autoload.php');
+```
+
+and then instantiate the reader class normally:
+
+```php
+use MaxMind\Db\Reader;
+$reader = new Reader('example.mmdb');
+```
+
+## Installation (RPM)
+
+RPMs are available in the [official Fedora repository](https://apps.fedoraproject.org/packages/php-maxminddb).
+
+To install on Fedora, run:
+
+```bash
+dnf install php-maxminddb
+```
+
+To install on CentOS or RHEL 7, first [enable the EPEL repository](https://fedoraproject.org/wiki/EPEL)
+and then run:
+
+```bash
+yum install php-maxminddb
+```
+
+Please note that these packages are *not* maintained by MaxMind.
+
+## Usage ##
+
+## Example ##
+
+```php
+<?php
+require_once 'vendor/autoload.php';
+
+use MaxMind\Db\Reader;
+
+$ipAddress = '24.24.24.24';
+$databaseFile = 'GeoIP2-City.mmdb';
+
+$reader = new Reader($databaseFile);
+
+// get returns just the record for the IP address
+print_r($reader->get($ipAddress));
+
+// getWithPrefixLen returns an array containing the record and the
+// associated prefix length for that record.
+print_r($reader->getWithPrefixLen($ipAddress));
+
+$reader->close();
+```
+
+## Optional PHP C Extension ##
+
+MaxMind provides an optional C extension that is a drop-in replacement for
+`MaxMind\Db\Reader`. In order to use this extension, you must install the
+Reader API as described above and install the extension as described below. If
+you are using an autoloader, no changes to your code should be necessary.
+
+### Installing Extension ###
+
+First install [libmaxminddb](https://github.com/maxmind/libmaxminddb) as
+described in its [README.md
+file](https://github.com/maxmind/libmaxminddb/blob/master/README.md#installing-from-a-tarball).
+After successfully installing libmaxmindb, run the following commands from the
+top-level directory of this distribution:
+
+```
+cd ext
+phpize
+./configure
+make
+make test
+sudo make install
+```
+
+You then must load your extension. The recommend method is to add the
+following to your `php.ini` file:
+
+```
+extension=maxminddb.so
+```
+
+Note: You may need to install the PHP development package on your OS such as
+php5-dev for Debian-based systems or php-devel for RedHat/Fedora-based ones.
+
+## 128-bit Integer Support ##
+
+The MaxMind DB format includes 128-bit unsigned integer as a type. Although
+no MaxMind-distributed database currently makes use of this type, both the
+pure PHP reader and the C extension support this type. The pure PHP reader
+requires gmp or bcmath to read databases with 128-bit unsigned integers.
+
+The integer is currently returned as a hexadecimal string (prefixed with "0x")
+by the C extension and a decimal string (no prefix) by the pure PHP reader.
+Any change to make the reader implementations always return either a
+hexadecimal or decimal representation of the integer will NOT be considered a
+breaking change.
+
+## Support ##
+
+Please report all issues with this code using the [GitHub issue tracker](https://github.com/maxmind/MaxMind-DB-Reader-php/issues).
+
+If you are having an issue with a MaxMind service that is not specific to the
+client API, please see [our support page](https://www.maxmind.com/en/support).
+
+## Requirements ##
+
+This library requires PHP 5.6 or greater.
+
+The GMP or BCMath extension may be required to read some databases
+using the pure PHP API.
+
+## Contributing ##
+
+Patches and pull requests are encouraged. All code should follow the PSR-1 and
+PSR-2 style guidelines. Please include unit tests whenever possible.
+
+## Versioning ##
+
+The MaxMind DB Reader PHP API uses [Semantic Versioning](https://semver.org/).
