Upgrading Axiom from v0.7.x to v0.8.0 - Tailwind CSS v2.
Axiom's v0.8.0 release is a major upgrade from v0.7.x and includes some breaking changes due to changes in Tailwind CSS v2.
In general the upgrade doesn't change anything major within a deployed Axiom website, as the changes are mainly on the build side.
