@Christopher The pull requests are usually handled by ericgaspar. There is currently no request. However, v 9.2 was just released today. It usually takes a few days. But there have also been phases this year where several new versions have already been released and YH has not implemented them. (YH: 8.8.6 HZ-Repo: 9.0.0)
I was also asked if I would like to take over the support. I then looked into the packaging at YH and decided not to do it. It would have been too time-consuming to familiarise myself with all the material and processes.

That's why I deleted the YH installation of my hub and installed a my_webapp. This allowed me to carry out the normal Hubzilla installation process.
