Firebird 1.5.3 PT_BR
Paulo Henrique Albanez informs that a non-oficial version of Firebird 1.5.3 for Windows, with supports to collate PT_BR (case insensitive) is available for download here. A Linux version will be available shortly.
This version is mainly for brazilians and other portuguese speakers people who wants to get the benefits of case/accent insensitive collation for ISO8859_1/WIN1252 charsets, while FB 2.0 is not released.
