1.7.0 (2020-03-02)

MLflow 1.7.0 includes several major features and improvements and some notable breaking changes.

MLflow support for Python 2 is now deprecated and will be dropped in a future release. At that point, existing Python 2 workflows that use MLflow will continue to work without modification, but Python 2 users will no longer get access to the latest MLflow features and bugfixes. We recommend that you upgrade to Python 3 - see for a migration guide.

Breaking changes to Model Registry REST APIs:

Model Registry REST APIs have been updated to be more consistent with the other MLflow APIs. With this release Model Registry APIs are intended to be stable until the next major version.

  • Python and Java client APIs for Model Registry have been updated to use the new REST APIs. When using an MLflow client with a server using updated REST endpoints, you won't need to change any code but will need to upgrade to a new client version. The client APIs contain deprecated arguments, which for this release are backward compatible, but will be dropped in future releases. (#2457, @tomasatdatabricks; #2502, @mparkhe).
  • The Model Registry UI has been updated to use the new REST APIs (#2476 @aarondav; #2507, @mparkhe)
