Mwepụta nke OpenBSD 6.9

Ewepụtala ntọhapụ nke sistemụ arụmọrụ UNIX dị ka OpenBSD 6.9 n'efu. Achọpụtara na nke a bụ mwepụta nke 50th nke ọrụ a, nke ga-agba afọ 26 n'afọ a. Theo de Raadt tọrọ ntọala OpenBSD na 1995 mgbe esemokwu ya na ndị mmepe NetBSD gasịrị, n'ihi nke a jụrụ Theo ohere ịnweta ebe nchekwa NetBSD CVS. Mgbe nke a gasịrị, Theo de Raadt na otu ndị nwere mmasị na-emepụta sistemụ arụmọrụ ọhụrụ nke dabeere na NetBSD isi mmalite, ihe mgbaru ọsọ mmepe bụ isi (na-akwado nyiwe ngwaike 13), nhazi nhazi, ọrụ ziri ezi, nchekwa na-arụ ọrụ. na ngwa ọrụ cryptographic agbakwunyere.
