September 2020 VCL release ("Cheerios")
Today the minimum version of VCL available across our network increased, unlocking the following changes:
Release names
To make them more fun and memorable, we've begun giving each VCL release, starting with the current one, a themed codename. The current theme is food items.
Variable re-categorization
We have re-categorized a lot of VCL variables in this release to reduce the number classified as miscellaneous. The reference pages for these variables have moved to new URLs. The old ones will redirect.
