* [BC BREAK] renamed "field_*" theme blocks to "form_*" and "field_widget" to

"input"

* The method `guessMinLength()` of FormTypeGuesserInterface was deprecated

and will be removed in Symfony 2.3. You should use the new method

`guessPattern()` instead which may return any regular expression that

is inserted in the HTML5 attribute "pattern".
