in earlier versions running DRC regenerated all zones
now in later nightlies it doesn't
touching each and every zone seems to be the only way.
what is the correct way to get them regenerated all at once ?
Does the shortcut "B" still work?
It might still be a good idea to ask the developers why DRC does not regenerate all zones now. Maybe create a bug report as this is definitely a regression.
i was unaware of that key
did not find it in the menus
The "?" shortcut might be helpful. It lists everything that can be done via a shortcut.
Also context menu on a zone -> Zones -> Fill All
... and in the latest nightly builds it's an option in the DRC dialog, off by default because it modifies the board before doing the DRC check.
