@elfkuzco @rgaudin shall we proceed with this 0.9.1 release so that we make changes of #12 available to the Zimfarm or do you feel like we might need more and should wait a little bit?

@elfkuzco did you confirm that this #12 PR is sufficient / OK for implementing required changes in Zimfarm by using directly the main branch in Zimfarm dependencies?

[rgaudin]

In favor of releasing
