-### Changed
-- Function `sendRequest` of `\Http\Adapter\Guzzle6\Client` used to throw a `\UnexpectedValueException`. Now it throws a 
-`Http\Adapter\Guzzle6\Exception\UnexpectedValueException` that extends the `\UnexpectedValueException` and implements
-the `Psr\Http\Client\ClientExceptionInterface`. This is done in order to be PSR-18 compliant.
+### Fixed
+- `\Http\Adapter\Guzzle6\Client::sendRequest` no longer throws any exceptions that do not implement
+  the PSR exception interface.
+
+  Instead of `\UnexpectedValueException` we now throw `Http\Adapter\Guzzle6\Exception\UnexpectedValueException`
+  (which extends `\UnexpectedValueException` and implements `Psr\Http\Client\ClientExceptionInterface`).
 
-- Function `sendRequest` of `\Http\Adapter\Guzzle6\Client` used to throw a `\RuntimeException`. Now it throws a 
-`Http\Client\Exception\TransferException` that extends the `\RuntimeException` and implements
-the `Psr\Http\Client\ClientExceptionInterface`. This is done in order to be PSR-18 compliant.
+  Instead of `\RuntimeException` we now throw `Http\Client\Exception\TransferException`
+  (which extends `\RuntimeException` and  implements `Psr\Http\Client\ClientExceptionInterface`).
