+# CHANGELOG
+
+## 2.3.0 - 2016-01-05
+
+* Added support for [JEP-9](https://github.com/jmespath/jmespath.site/blob/master/docs/proposals/improved-filters.rst),
+  including unary filter expressions, and `&&` filter expressions.
+* Fixed various parsing issues, including not removing escaped single quotes
+  from raw string literals.
+* Added support for the `map` function.
+* Fixed several issues with code generation.
+
+## 2.2.0 - 2015-05-27
+
+* Added support for [JEP-12](https://github.com/jmespath/jmespath.site/blob/master/docs/proposals/raw-string-literals.rst)
+  and raw string literals (e.g., `'foo'`).
+
+## 2.1.0 - 2014-01-13
+
+* Added `JmesPath\Env::cleanCompileDir()` to delete any previously compiled
+  JMESPath expressions.
+
+## 2.0.0 - 2014-01-11
+
+* Moving to a flattened namespace structure.
+* Runtimes are now only PHP callables.
+* Fixed an error in the way empty JSON literals are parsed so that they now
+  return an empty string to match the Python and JavaScript implementations.
+* Removed functions from runtimes. Instead there is now a function dispatcher
+  class, FnDispatcher, that provides function implementations behind a single
+  dispatch function.
+* Removed ExprNode in lieu of just using a PHP callable with bound variables.
+* Removed debug methods from runtimes and instead into a new Debugger class.
+* Heavily cleaned up function argument validation.
+* Slice syntax is now properly validated (i.e., colons are followed by the
+  appropriate value).
+* Lots of code cleanup and performance improvements.
+* Added a convenient `JmesPath\search()` function.
+* **IMPORTANT**: Relocating the project to https://github.com/jmespath/jmespath.php
+
+## 1.1.1 - 2014-10-08
+
+* Added support for using ArrayAccess and Countable as arrays and objects.
+
+## 1.1.0 - 2014-08-06
+
+* Added the ability to search data returned from json_decode() where JSON
+  objects are returned as stdClass objects.

+============
+jmespath.php
+============
+
+JMESPath (pronounced "jaymz path") allows you to declaratively specify how to
+extract elements from a JSON document. *jmespath.php* allows you to use
+JMESPath in PHP applications with PHP data structures. It requires PHP 5.4 or
+greater and can be installed through `Composer <http://getcomposer.org/doc/00-intro.md>`_
+using the ``mtdowling/jmespath.php`` package.
+
+.. code-block:: php
+
+    require 'vendor/autoload.php';
+
+    $expression = 'foo.*.baz';
+
+    $data = [
+        'foo' => [
+            'bar' => ['baz' => 1],
+            'bam' => ['baz' => 2],
+            'boo' => ['baz' => 3]
+        ]
+    ];
+
+    JmesPath\search($expression, $data);
+    // Returns: [1, 2, 3]
+
+- `JMESPath Tutorial <http://jmespath.org/tutorial.html>`_

+
+PHP Usage
+=========
+
+The ``JmesPath\search`` function can be used in most cases when using the
+library. This function utilizes a JMESPath runtime based on your environment.
+The runtime utilized can be configured using environment variables and may at
+some point in the future automatically utilize a C extension if available.
+
+.. code-block:: php
+
+    $result = JmesPath\search($expression, $data);
+
+    // or, if you require PSR-4 compliance.
+    $result = JmesPath\Env::search($expression, $data);
+
+Runtimes
+--------
+
+jmespath.php utilizes *runtimes*. There are currently two runtimes:
+AstRuntime and CompilerRuntime.
+
+AstRuntime is utilized by ``JmesPath\search()`` and ``JmesPath\Env::search()``
+by default.
+
+AstRuntime
+~~~~~~~~~~
+
+The AstRuntime will parse an expression, cache the resulting AST in memory,
+and interpret the AST using an external tree visitor. AstRuntime provides a
+good general approach for interpreting JMESPath expressions that have a low to
+moderate level of reuse.
+
+.. code-block:: php
+
+    $runtime = new JmesPath\AstRuntime();
+    $runtime('foo.bar', ['foo' => ['bar' => 'baz']]);
+    // > 'baz'
+
+CompilerRuntime
+~~~~~~~~~~~~~~~
+
+``JmesPath\CompilerRuntime`` provides the most performance for
+applications that have a moderate to high level of reuse of JMESPath
+expressions. The CompilerRuntime will walk a JMESPath AST and emit PHP source
+code, resulting in anywhere from 7x to 60x speed improvements.
+
+Compiling JMESPath expressions to source code is a slower process than just
+walking and interpreting a JMESPath AST (via the AstRuntime). However,
+running the compiled JMESPath code results in much better performance than
+walking an AST. This essentially means that there is a warm-up period when
+using the ``CompilerRuntime``, but after the warm-up period, it will provide
+much better performance.
+
+Use the CompilerRuntime if you know that you will be executing JMESPath
+expressions more than once or if you can pre-compile JMESPath expressions
+before executing them (for example, server-side applications).
+
+.. code-block:: php
+
+    // Note: The cache directory argument is optional.
+    $runtime = new JmesPath\CompilerRuntime('/path/to/compile/folder');
+    $runtime('foo.bar', ['foo' => ['bar' => 'baz']]);
+    // > 'baz'
+
+Environment Variables
+^^^^^^^^^^^^^^^^^^^^^
+
+You can utilize the CompilerRuntime in ``JmesPath\search()`` by setting
+the ``JP_PHP_COMPILE`` environment variable to "on" or to a directory
+on disk used to store cached expressions.
+
+Testing
+=======
+
+A comprehensive list of test cases can be found at
+https://github.com/jmespath/jmespath.php/tree/master/tests/compliance.
+These compliance tests are utilized by jmespath.php to ensure consistency with
+other implementations, and can serve as examples of the language.
+
+jmespath.php is tested using PHPUnit. In order to run the tests, you need to
+first install the dependencies using Composer as described in the *Installation*
+section. Next you just need to run the tests via make:
+
+.. code-block:: bash
+
+    make test
+
+You can run a suite of performance tests as well:
+
+.. code-block:: bash
+
+    make perf
