First 1.7.666 bugs are in

The big one seems to be a problem with rendering sky. In some maps we have a situation where the sky (or parts of the sky) ain't being drawn.

What's wrong with this seems to be cases of the first thing every mapper should learn when sealing a leaky map - do NOT put a great big box around the map.

Here we actually do seem to have a great big box around these maps, and it's drawn at a distance that makes the dynamically set far clipping plane go wrong.

There are other possible causes, but I'm going to download some maps and mods tomorrow and start testing this theory for starters.

There are a few solutions here, but the one I think I'm going to go for is just extending the minimum size of the far plane to the standard max extent of a Quake map, which is about 14188.

A second bug is flickering instanced brush models (ammo boxes, etc). I must admit that I haven't observed this myself in any of my testing with Intel or NVIDIA hardware (I don't have any ATI), but what I am curious to know is if it is a new thing or if it also happened in 1.7.3; at least that way I can start identifying what changed to possibly cause it.

Thankfully there seems to be no crashes this time... (fingers crossed, and hoping I haven't tempted fate by saying that!)

What this means is that there will probably be a bugfix release - 1.7.666b most likely.
