Let's Make Release Upgrades Great Again!
summary
Claims a working rebar3 plugin that generates appup/release tarballs, computes module order with crossref dependency detection, and injects code for automatic state migration between versions. Demonstration upgrades from 1.0.11 to 1.0.12 and to 1.0.20 show it builds appup instructions, loads modules, updates supervisors, and converts record-based gen_server state so the running system ends up on the new release without downtime.
