Ho lokolloa ha OpenBSD 7.3

Ho lokolloa ha sesebelisoa sa mahala sa UNIX-joaloka OpenBSD 7.3 se hlahisoa. Morero oa OpenBSD o thehiloe ke Theo de Raadt ka 1995 kamora likhohlano le bahlahisi ba NetBSD, ka lebaka leo Theo a hanetsoeng ho fumana polokelo ea NetBSD CVS. Kamora sena, Theo de Raadt le sehlopha sa batho ba nang le maikutlo a tšoanang ba thehile sistimi e ncha e bulehileng ea ts'ebetso e thehiloeng ho sefate sa mohloli oa NetBSD, sepheo sa mantlha sa nts'etsopele eo e neng e le ho ts'oaroa (li-platform tsa hardware tse 13 li tšehetsoa), maemo, ts'ebetso e nepahetseng, ts'ireletso e matla. le lisebelisoa tse kopaneng tsa li-cryptographic.
