Current Series Release Notes

19.0.0-76

New Features

• The action std.mistral_http will now retrun an error if the HTTP request fails. Previously the task would still go into the RUNNING state and wait to be completed by the external resource.

Deprecation Notes

• The coordination service inside mistral has been used only to list the mistral services list behind the endpoint v2/services. This feature is not enabled by default and needs a specific coordinator backend_url configuration to be set for mistral to answer the services list correctly. Coordination rely on the tooz project and, depending on the driver in use, may need eventlet monkeypatching. Because we want to get rid of all eventlet code inside mistral, the v2/services endpoint is now deprecated and all coordination code will be dropped in the next cycle.

• The kombu RPC driver in mistral is now deprecated and will be removed in the next cycle. In the effort to keep mistral up and running, we decided to drop experimental features like kombu RPC driver, which does not bring anything more than the default oslo.messaging driver.
