Galaxy shows collection documentation. I think this has started somewhere during the last months, although I can’t find the announcement anymore.
Whatever, if you look at e.g. vmware_cluster_drs you’ll see L(new vmware.vmware collection,http://forum.ansible.com/t/5880) and M(vmware.vmware.cluster_drs).
Shouldn’t this be formatted as links like here?
Sorry if this has been asked already, but I wasn’t able to find anything about this either here or on GitHub.
It started with the switch to galaxy_ng, i.e. roughly one year ago 
Yes. I guess it’s a bug that in these parts Ansible markup is not formatted.
The corresponding code is here: ansible-hub-ui/src/components/render-plugin-doc/render-plugin-doc.tsx at master · felixfontein/ansible-hub-ui · GitHub Applying this.applyDocFormatters() to doc.deprecated.why and doc.deprecated.alternative should fix this.
Thanks @felixfontein! I’ve opened this issue and mentioned your suggestion there.
