Expected behaviour: Channel is resolved to latests with every update operation.

Actual behaviour: Channel version is fixed in Prospero configuration and no attempt to resolve latest is done.

Prospero requires hardcoded channel version (in prospero-config.yaml), which doesn't allow the update. By default, latest version can be taken from maven-metadata.xml (or maven-metadata-local.xml), but prospero requires hardcoded version of channel, so it seems that any update can be made by change of already released maven artifact (channel in this case), which is against maven architecture.

So prospero should be able to work without hardcoded version of channel as well.
