@LukaszHorodecki @pixelfed Gosh! It is not about who maintains particular repo, but about the general page rules. I remember I was reading something about the topic a while ago. Someone asked similar questions too. The answer were something like: all versions - stable, beta and/or alpha must be kept separately and released form different repos as such. It was due to the avoiding mismatched versions, signatures, updating issues etc. That's all I remember from the reading.
@MartinaNeumayer Once again: this it the Pixelfed repo with development releases , but it the most recent one isn't there, and that's why I asked.
