I currently do not understand the way of working at epic. Currently its: make release -> create bugs -> create new release -> fix bugs in next release etc.
The result is no stable release at all, every release has some big issues. Why not apply bug fix patches during the release? Preview of course solves the biggest issues, but it still doesn’t guarantee a stable release overall. You can’t expect people to integrate bugfixes to a previous release on their own. E.g. its hard for small teams to get a stable product. For the bigger teams out there it is easily possible to look into bugfixes in next releases and try to get those working.
