Nutanix AOS 5.5 Released

Nutanix has released version 5.5 (codename “Obelix”) of their Acropolis Operating System (AOS). For Nutants, this release is the capstone of Nutanix goodness. Be aware that the full list of Obelix features could not fit into one major release and is actually being released over the coming months as a series of minor releases (5.5.0, 5.5.1, 5.5.2, etc.).

This obviously also means that the supporting components of the Nutanix eco-system also have new releases to complement AOS, namely AHV, Prism Central, NCC, LCM and Foundation. Please refer to the resources section at the end for links to downloads and release notes.
