 ### Added
 - `multi databases` feature on a [proposal](https://github.com/phpMv/ubiquity/issues/60) from [@Gildonei](https://github.com/gildonei)
 ### Changed
 - `Startup` class optimization
 
 #### Breaking change possible
-- Database startup with `DAO::startDatabase($config)` in `services.php` file is useless.
+Induced by multi database functionality:
+- Database startup with `DAO::startDatabase($config)` in `services.php` file is useless, no need to start the database, the connection is made automatically at the first request.
 - Use `DAO::start()` in `services.php` file when using several databases (with `multi db` feature)
-- For optimization reasons, the classes used only in development (common to devtools and webtools) have been relocated in the `phpmv/ubiquity-dev` package.
