NOTE: This issue is part of the "SymfonyCon 2014 Madrid Hackday" effort to add logs for every 2.7 deprecated feature. This is needed before removing those features in 3.0 version. Please, add you name in a comment of this issue if you are going to work on this.

The constants ROUND_HALFEVEN, ROUND_HALFUP and ROUND_HALFDOWN in class NumberToLocalizedStringTransformer were renamed to ROUND_HALF_EVEN, ROUND_HALF_UP and ROUND_HALF_DOWN.
