2) - cdio_get_cdtext no longer takes track as an argument - cdtext_get, cdtext_get_const, cdtext_set require track argument 3) Language, Genre, Genre Code and Encoding Fields are now properly parsed and stored in the cdtext object 4) Added public function cdio_get_cdtext_raw to extract the binary CD-Text 5) Added CDTEXTFILE keyword logic in cue sheet parser. Parses binary/raw CD-Text files 6) Added cdtext_genre2str to convert genre code 7) altered the example programs, test drivers, cdda-player and cd-info to work with these changes 8) Added test case 9) A few smaller changes A disc either holds CD-Text for all the tracks or does not hold any. Therefore a CD-Text object for the whole disc seems more natural to me. It also enables us to store global fields, like genre, encoding, language. Patch was tested on GNU/Linux 32 bit running Gentoo.
