I'm upgrading to eZCommunity 4.2011

And I get a nice error:
Fatal error: Call to undefined function ezi18n() in .../ezpublish_community_project-4.2011-with_ezc/extension/ezstarrating/datatypes/ezsrrating/ezsrratingtype.php on line 36
Fatal error: eZ Publish did not finish its request

Error is in there:

parent::__construct( self::DATA_TYPE_STRING, ezi18n( 'extension/ezstarrating/datatype', 'Star Rating', 'Datatype name' ), array( 'serialize_supported' => true ) );

ezi18n() has replaced by ezpI18n() as far as I can remember...

Affects the 4.2011, but I don't find it in the versions
