#### 2.3.4

* Added `@prepare` annotation to make realtime configuration for tests in Cest and Test classes. [See documentation](http://codeception.com/docs/06-ModulesAndHelpers#Runtime-Configuration-of-a-Test).
 
 Example: disabling Doctrine2 database transaction for a test

```php
<?php
/*
 * @prepare disableTransactions
 */
function testDoctrine()
{
}

protected function disableTransactions(Doctrine2 $module)
{
   $module->_reconfigure(['cleanup' => false);
}
```
* [WebDriver] **SmartWait**. Automatically waits for a few extra seconds for element to appear on a page before failing. Can reduce high usage of `wait*` methods. [See Documentation](http://codeception.com/docs/03-AcceptanceTests#SmartWait)
* Added [RunProcess extension](http://codeception.com/extensions#RunProcess). Use it to start/stop Selenium (or other process) automatically for a test suite.   
* [WebDriver] Customization improvements:
    * added `start` option to disable autostart of a browser for tests. (can be useful for Cloud testing setups)
    * added `_capabilities` method for setting desired capabilities in runtime (can be combined with `@prepare` annotation)
    * `_initializeSession` and `_closeSession` can be used in Helpers to start and stop browser manually (combine with `start: false` config)
* Fixed running a single test from a global config when using included configs. See #4366 by @zebraf1 (improves PhpStorm integration)
* [Doctrine2][Laravel5][Yii2][Phalcon] Print debug information for started/stopped transactions in tests. See #4352
* [PhpBrowser][Frameworks] click with context respects base tag #4330 by @Naktibalda.
* [Yii2] Split `cleanup` configuration option (backward-compatible) to: (#4379 by @leandrogehlen) 
  * `cleanup` - to cleanup loaded fixtures
  * `transaction` - wrap tes into transaction
* [Asserts] Added `assertStringStartsWith` and `assertArraySubset` by @guidocella
* [Db] Added `updateInDatabase` method by @eXorus. See #4385

* [Symfony] Fixed printing debug response when `Symfony::extractRawRoles()` failed on security collector (Symfony >= 3.3) #4309 by @Basster
* [Laravel5] Fixed bug with `disable_exception_handling` functionality. See #4370. By @janhenkgerritsen
* [Db] Added `grabColumnFromDatabase` to fetch values from the column in database. By @RebOOter

#### 2.3.3

* Fixed running with `--coverage`, `--xml`, `--html` options without parameters (Symfony Console 3.3 compatibility).
* Removed `files` section from `composer.json` (regression from 2.3.2) to avoid unintentionally loading shim files. Fixes [Yii migration issue](https://github.com/yiisoft/yii2/issues/14226).
* [WebDriver] `saveScreenshot` allows to save screenshots with no name passed in. See #4263 by @eXorus
* [REST][PhpBrowser] Fixed #4287, using empty values for headers by @tobiastom.
* Phar `self-update` downloads php5.4 build if php version <7.0. Fixes #4269

* [Db] Fixed: Database has been cleaned up between tests even with `cleanup: false`.  
* [Db] Made `dump` optional if `populator` is set. Fixes #4247
