I have extended the deployment workflow for docs.operaton.org. The workflow now executes a script that reads all releases of operaton/operaton and downloads javadoc.zipand rest-api.zip when existent. This gets unpacked and uploaded to the website.
I will further make sure that these artifacts are deployed with the next release. For 1.0.0-rc-1 I have deployed them manually. But a change to the release workflow will soon come.
