[2.5.1] - 2021-03-24 Added - Extend GraphQL `issues` API with `aliens` topic. The issues warns if two separate clusters share the same cluster cookie. - Enhance error messages when they're transferred over network. Supply it with the connection URI. Fixed - Don't skip two-phase commit prematurely. From now on, the decision to skip the `apply_config` is made by every instance individually. The validation step is never skipped. - Avoid WebUI and `pool.map_call` requests hanging because of network connection problems. - Fix unclear "Timeout exceeded" error. It affects v2.5.0 two-phase commit when an instance is stuck in `ConfiguringRoles` state. - Make the "Replication isn't running" issue critical instead of a warning.
