Red Hat Enterprise Linux 7.7 Kutulutsidwa

Kampani ya Red Hat anamasulidwa Kugawa kwa Red Hat Enterprise Linux 7.7. Zithunzi zoyika za RHEL 7.7 zilipo tsitsani ogwiritsa ntchito olembetsedwa a Red Hat Customer Portal okha ndikukonzekera x86_64, IBM POWER7+, POWER8 (ndian yayikulu ndi endian yaying'ono) ndi zomangamanga za IBM System z. Source phukusi akhoza dawunilodi kuchokera Git repository Pulogalamu ya CentOS.

Nthambi ya RHEL 7.x imasungidwa mofanana ndi nthambi RHEL 8.x ndipo adzathandizidwa mpaka June 2024. Kutulutsidwa kwa RHEL 7.7 ndiye gawo lomaliza la gawo lalikulu lothandizira kuphatikiza kukonza magwiridwe antchito. RHEL 7.8 zidzadutsa mu gawo lokonza, pomwe zoyambira zidzasinthira ku kukonza zolakwika ndi chitetezo, ndikuwongolera pang'ono kuti zithandizire machitidwe ofunikira a hardware.
