OpenOffice_org1-1.1.3-4.2 released TWICE (?)

Hi, I couldn't find a logical explanation, maybe someone could help me to understand the situation: Last month the youpdated version '1.1.3-4.2' of OpenOffice_org1 was released and few days ago '1.1.3-4.3' appeared on the mirrors. Until this point everything seems be fine, but while comparing the .spec files of the above source rpms, interestingly only a single line, containing the version numbers differs in them. Is there an explanation to release the same YOU update actually twice with different version numbers or do I miss something? Thanks, Pelibali
