MLMD v0.15.1

Release 0.15.1

Major Features and Improvements

• Add migration options to gRPC MetadataStoreServerConfig.
• Disable auto schema migration by default during connection. The user needs
  to explicitly enable it when connecting an older database.
• Support SSL options when using MySQL metadata source.

Bug Fixes and Other Changes

• Fixes MySQL errors with concurrent connection to an empty database. Now,
  MLMD returns Aborted when concurrent connection error happens and the caller
  can retry appropriately.

• Deprecates disable_upgrade_migration in python MetadataStore constructor.
