Shielding VCL Rendering, New VCL Syntax
Backend definitions with shielding enabled, and which use the 'shield' director, now have a simplified syntax that incorporates health checks, loop checks, and other checks in a single line of VCL.
Additionally, the minimum version of VCL available across our network increased, unlocking the following changes:
New variable
New function
Prior change: Remove beta tags from the Secret Store docs
Following change: CLI v10.8.9
