We said 2.1.10 was the next version to be released and we weren’t kidding around. Though this patch may not look like it contains much, it makes modifications (especially Lua-based ones) much less prone to breaking in unusual and frustrating ways.

• Longstanding issues with Lua’s stability have been fixed.
  • Lua can tolerate large scripts much better.
  • Lua can handle multiple separate scripts running at the same time much better than before; you should no longer have to fiddle around with adding WAD files in different orders to make the game stable.
  • The game no longer crashes if scripts are added via the command line (-file) that replace commands normally present in the game.
• The game no longer crashes if you try to host your own server after failing to join someone else’s server due to not being able to download WAD files.
• The game no longer crashes at the end of the last special stage, and the shrink ray section now works again.
• A few minor level design fixes.
