Restating my question about planned updates to the underlying version of Hugo. Finally bumped into the scenario I predicted (wasting a bunch of time because the entirety of the Hugo documentation is not actually reliable as to including the version at which point functionality is supported). I was trying to Hugofy my navigation by going back to the creation of menu items. Took a while to stumble upon the reason I couldn’t get menu entry parameters working.
So I guess the official question would be, are there any plans?
