0.9.4

Released: July 31, 2017

• [bug] [runtime] Added an additional attribute to the new
  EnvironmentContext.configure.on_version_apply API,
  MigrationInfo.up_revision_ids, to accommodate for the uncommon
  case of the alembic stamp command being used to move from multiple
  branches down to a common branchpoint; there will be multiple
  "up" revisions in this one case.
