When will an update be ready?
Right now Gneiss, GneissCMS, Thanet writers and half a dozen other things depend only on me (Matt) tog et them done. So the honest answer ist hat while I would like to have everything ready for you by yesterday, the truth is that I have no timetable for you at all. Please rest assured that whatever it is you are waiting on, I am getting there as fast as I can.
You can make things slightly faster by contributing on Github or by sponsoring Matt on Patreon or simply slap some cash on the table to entice Matt (or someone like him) to prioritise on that thing you really want. Matt monitors bountysource.com and you can sponsor open tickets on github to be closed faster.
