 All Notable changes to `gmponos\guzzle_logger` will be documented in this file
 
+## 0.3.0 - 2018-08-23

+### Changed
+- The package was reading the headers of the Request/Response and if they contained `application/json` the body
+was parsed into an array in order to be better readable in the logger. This has changed to match a regular expression

+- According to PHPStorm indication the `ext-json` needs to be installed in order for the package to work. Therefore
+it was added as a requirement to `composer.json`
