Removed official maps

In the past maps got removed from the official game and in the future more will be removed respectively replaced with quality maps.

If server admins still want to host them, here are pk3s:

• Removed in 0.8
  
• Red Planet
  
  Removed in 0.8.1
  
• Abyss
  
• Lightspeed
  
• Newtonian Nightmare
  
  Removed in 0.8.2
  
• G-23
  

Removed in 0.8.6:

• Drain
  
• Oil Rig
  

In the past maps got removed from the official game and in the future more will be removed respectively replaced with quality maps.

So, what does this mean?  Does it mean that the maps which are removed will be re-done to be more compatible with no glitches, or are they just gone forever? Or were these maps removed because the game-play wasn't good?

Team votes were held to decide their removal:

Oil Rig: https://xonotic.org/teamvotes/384/
Drain: https://xonotic.org/teamvotes/371/
Newtonian Nightmare: https://xonotic.org/teamvotes/303/
Lightspeed: https://xonotic.org/teamvotes/288/
Red Planet: https://xonotic.org/teamvotes/169/
G-23: https://xonotic.org/teamvotes/321/
Abyss doesn't seem to have been given a vote...

As the game and community has evolved, so have the available maps. As such, older maps with less enjoyable gameplay were phased out in favour of newer more popular ones.
