Zaiming Shi 5bb0cccb53 refactor(build): Clean up app version management Starting from 5.0.0, all apps in apps dir should follow semver strictly. Do not use the umbrella project's release tags. The universal tags made sense when we have applications scattered in different repos. Now since this is an umbrella project, it is enough to have a single package level version number corelated with git tag.		2020-12-01 23:22:33 +01:00
