Current behaviour

When multiple commits are made in a short period of time, the documentation generation process will execute as separate processes. It is possible that the documentation due to a previous commit is deployed after a newer commit.

Expected behaviour

it was discussed in the official channel that we should stop the deployment process of all the older commits.
