;; 2009-03-08 (mike.dld) ;;
;; bug-fixes: ;;
;; - moved buffer bound check in libini._.low.read_value up (reported by Insolor) ;;
;; new features: ;;
;; - comments support (char is ini.COMMENT_CHAR, defaults to ';') ;;
;; inline comments are not supported ;;
;; 2008-12-29 (mike.dld) ;;
;; bug-fixes: ;;
;; - unnecessary 'stosb' in ini.get_str was causing problems ;;
;; new features: ;;
;; - new functions: ini.get_color and ini.set_color ;;
;; 2008-08-06 (mike.dld) ;;
;; changes: ;;
;; - split private procs into libini_p.asm, added comments ;;
;; 2008-02-07 (mike.dld) ;;
;; changes: ;;
;; - renamed all *.aux.* to *._.* to match overall libraries design ;;
;; 2007-09-26 (mike.dld) ;;
;; bug-fixes: ;;
;; - value was not correctly trimmed (reported by diamond) ;;
;; 2007-08-01 (mike.dld) ;;
;; bug-fixes: ;;
;; - serious defect in ini.set_str causing displaced write operations ;;
;; (reported by diamond) ;;
;; - another serious defect in ini.enum_keys introduced with refactoring ;;
;; changes: ;;
;; - callback for enum_keys now takes additional parameter - key value ;;
;; - handling trailing spaces in section/key/value ;;
;; 2007-05-19 (mike.dld) ;;
;; bug-fixes: ;;
;; - last char still wasn't read correctly ;;
;; - digits of number were reversed when using ini.set_int ;;
;; - now using 'ini.aux.unget_char' instead of dangerous 'dec esi' ;;
;; changes: ;;
;; - all non-public functions now start with ini.aux.* ;;
;; - added ini.enum_sections and ini.enum_keys ;;
;; - removed ini.query_sec (use ini.enum_* instead) ;;
