 ## 3.x-dev
 
+- Fixed a bug where a suffix when whitelisting files would default to `src`.
+  This would make reports not generate in case no `suffix` was defined in
+  configuration.
 - `phpunit/php-code-coverage` dependency version requirement has been updated
   from `~4.0|~5.0` to `~5.0` as we do not support version `4.0` anymore.
+- Updated README to list all configuration options
+- Updated `behat.yml.dist` so that it can be used as a proper example
+- `remote` driver is no longer activated by default
+- Version constraints in composer.json have been updated from `~` to `^`.
 
 
 ## [3.2.0] - 2017-10-17 - Guzzle 6.0 support release
