For each minor release (starting with Domino 4.5), Domino performs a set of validation tests against the most recent released version of Ray. The purpose of the tests is to cover the integration surface between the Domino platform and the on-demand Ray clusters that the platform orchestrates. The testing is not intended to be a comprehensive test of Ray itself since Domino does not modify that software.
The validated and supported version of Ray is 2.55.1. Other Ray versions are likely to function properly, but Domino cannot offer technical support.
