+# Deprecations
+
+This document lists all the planned deprecations.
+
+## Handlers will be removed in 2.0
+
+The `Handler` type and associated calls will be removed in version 2.0.
+
+### Upgrade path
+
+You should create your own implementation for handling OOP usage,
+but it's recommended to move away from using an OOP-style wrapper entirely.
+
+The reason for this is that it's too easy for implementation details (for
+your application this is Flysystem) to leak into the application. The most
+important part for Flysystem is that it improves portability and creates a
+solid boundary between your application core and the infrastructure you use.
+The OOP-style handling breaks this principle, therefore I want to stop
+promoting it.

+CHANGELOG
+---------
+
+### v3.4.1, 2019.10.19
+
+- Fixed a [bug](https://github.com/opis/closure/issues/40) that prevented serialization to work correctly.
+
+### v3.4.0, 2019.09.03
+
+- Added `createClosure` static method in `Opis\Closure\SerializableClosure`.
+This method creates a new closure from arbitrary code, emulating `create_function`,
+but without using eval
+
+### v3.3.1, 2019.07.10
+
+- Use `sha1` instead of `md5` for hashing file names in `Opis\Closure\ReflectionClosure` class
+
+### v3.3.0, 2019.05.31
+
+- Fixed a bug that prevented signed closures to properly work when the serialized string
+contains invalid UTF-8 chars. Starting with this version `json_encode` is no longer used
+when signing a closure. Backward compatibility is maintained and all closures that were 
+previously signed using the old method will continue to work.
+
+### v3.2.0, 2019.05.05
+
+- Since an unsigned closure can be unserialized when no security provider is set, 
+there is no reason to treat differently a signed closure in the same situation.
+Therefore, the `Opis\Closure\SecurityException` exception  is no longer thrown when 
+unserializing a signed closure, if no security provider is set.
+
+### v3.1.6, 2019.02.22
+
+- Fixed a bug that occurred when trying to set properties of classes that were not defined in user-land.
+Those properties are now ignored.
+
+### v3.1.5, 2019.01.14
+
+- Improved parser
+
+### v3.1.4, 2019.01.14
+
+- Added support for static methods that are named using PHP keywords or magic constants.
+Ex: `A::new()`, `A::use()`, `A::if()`, `A::function()`, `A::__DIR__()`, etc.
+- Used `@internal` to mark classes & methods that are for internal use only and
+backward compatibility is not guaranteed.
+
+### v3.1.3, 2019.01.07
+
+- Fixed a bug that prevented traits to be correctly resolved when used by an
+anonymous class
+- Fixed a bug that occurred when `$this` keyword was used inside an anonymous class
+
+### v3.1.2, 2018.12.16
+

+Serializable closures
+---------------------
+**Opis Closure** is a library that aims to overcome PHP's limitations regarding closure
+serialization by providing a wrapper that will make all closures serializable. 
+
+**The library's key features:**
+
+- Serialize any closure
+- Serialize arbitrary objects
+- Doesn't use `eval` for closure serialization or unserialization
+- Works with any PHP version that has support for closures
+- Supports PHP 7 syntax
+- Handles all variables referenced/imported in `use()` and automatically wraps all referenced/imported closures for
+proper serialization
+- Handles recursive closures
+- Handles magic constants like `__FILE__`, `__DIR__`, `__LINE__`, `__NAMESPACE__`, `__CLASS__`,
+`__TRAIT__`, `__METHOD__` and `__FUNCTION__`.
+- Automatically resolves all class names, function names and constant names used inside the closure
+- Track closure's residing source by using the `#trackme` directive
+- Simple and very fast parser
+- Any error or exception, that might occur when executing an unserialized closure, can be caught and treated properly
+- You can serialize/unserialize any closure unlimited times, even those previously unserialized
+(this is possible because `eval()` is not used for unserialization)
+- Handles static closures
+- Supports cryptographically signed closures
+- Provides a reflector that can give you information about the serialized closure
+- Provides an analyzer for *SuperClosure* library
+- Automatically detects when the scope and/or the bound object of a closure needs to be serialized
+in order for the closure to work after deserialization
+
+### Documentation
+
+The full documentation for this library can be found [here][documentation].
+
+### License
+
+**Opis Closure** is licensed under the [MIT License (MIT)][license].
+
+### Requirements
+
+* PHP ^5.4 || ^7.0
+
+## Installation
+
+**Opis Closure** is available on [Packagist] and it can be installed from a 
+command line interface by using [Composer]. 
+
+```bash
+composer require opis/closure
+```
+
+Or you could directly reference it into your `composer.json` file as a dependency
+
+```json
+{
+    "require": {
+        "opis/closure": "^3.4"
+    }
+}
+```
+
+### Migrating from 2.x
+
+If your project needs to support PHP 5.3 you can continue using the `2.x` version
+of **Opis Closure**. Otherwise, assuming you are not using one of the removed/refactored classes or features(see 
+[CHANGELOG]), migrating to version `3.x` is simply a matter of updating your `composer.json` file. 
+
+### Semantic versioning
+
+**Opis Closure** follows [semantic versioning][SemVer] specifications.
+
+### Arbitrary object serialization
+
+This feature was primarily introduced in order to support serializing an object bound 
+to a closure and available via `$this`. The implementation is far from being perfect 
+and it's really hard to make it work flawless. I will try to improve this, but I can 
+not guarantee anything. So my advice regarding the `Opis\Closure\serialize|unserialize` 
+functions is to use them with caution.
+
+### SuperClosure support
+
+**Opis Closure** is shipped with an analyzer(`Opis\Closure\Analyzer`) which 
+aims to provide *Opis Closure*'s parsing precision and speed to [SuperClosure].
