Error resolving db (~> 0.7.0, ~> 0.8.0)

[Lewis E. Bogan]

How do I update micrate (and granite) to use crystal-db 0.8.0? I'm using Crystal 0.32.1.
shard.yml snippet:

dependencies:
  pg:
    github: will/crystal-pg
  sqlite3:
    github: crystal-lang/crystal-sqlite3
  mysql:
    github: crystal-lang/crystal-mysql
  granite:
    github: amberframework/granite

Thanks in advance.

Adding version info to my shard.yml fixed this. Noob mistake!
