Release Notes: A small memory leak was fixed in rec_init(), and thus also in rel_init() and rep_init(). Error corrections were made in the software copy protection module. Wrong messages in Uninstall.exe were corrected. An error in processing empty images with GENERAL_PREP_ONLY was fixed. A rare error in binarization of gray images with a parameter setting different from PREP_GRAYTOBIN_MEDIUM was fixed. The algorithms for image zooming were improved. An additional parameter value, PREP_GRAYTOBIN_UNIFORM, was added to binarize gray images with one threshold only.
