From af998b58aadcacb0b0af6d3a33b0cd5ac9f7a8eb Mon Sep 17 00:00:00 2001 From: Ivo Radkov Date: Fri, 12 Jun 2026 11:17:09 +0300 Subject: [PATCH 1/2] Add cflinuxfs5 to available stacks documentation Document the cflinuxfs5 stack (derived from Ubuntu 24.04 LTS "Noble Numbat") as an additional Linux stack available in Cloud Foundry. cflinuxfs4 remains the default; operators enable cflinuxfs5 by applying the add-cflinuxfs5.yml experimental ops file from cf-deployment. Update the example 'cf stacks' output to reflect both ACTIVE stacks.
