Our normal workflow is to first update the latest stable branch with any updates, that means meta-mender/thud and overtime we try to backport to older branches e.g sumo and rocko. This is done “best effort wise” and timing could depend on many factors.

Please note that you need to add the following to e.g local.conf to enable the beta components,
PREFERRED_VERSION_pn-mender = "2.0.%"
PREFERRED_VERSION_pn-mender-artifact = "3.0.%"
PREFERRED_VERSION_pn-mender-artifact-native = "3.0.%"
