• Made the large weld (more than 127 props) algorithm much faster.
  
• Micro and minor optimizations.
  
• Fixed cleanning up smart welds.
  
• Max welds per prop can't be greater than 15 now.

• Optimizations and code cleanup.

• Added a "max welds per prop" option. Only applies when welding more than 127 props.
  
• Fixed a counting bug when welding all the selected props to one.
  
• Improved code formatting.

• Notification icons now work correctly in singleplayer.
  
• Added nice icons to the tool description.
  
• Fixed a bug when welding all selected props to a single prop.
  
• Fixed a bug with stages being set wrong.

• Ensured all default Sandbox entities are compatible.
  
• Added default support for more major addons like WAC, TDM, NeuroTec, and ACF.

Here is a big update for you guys!

• Added a config table at the top of the file to add support to specific base classes.
  
• The addition above also fixed not being able to weld to gmod entities. Wiremod, SCars, and the default Gmod entities are supported by default.
  
• Fixed welding more than 127 props! Now when you weld more than 127 props it will go through each prop, find the 10 closest props, and weld them. This keeps a fairly stable weld and works pretty darn fast.

• Reorganized the code a bit more to be easier to follow.

• Loads of optimizations and code cleanups, I wouldn't know where to start describing them.
  
• Among these changes the self:IsAllowedEnt() function was changed yet again, even better this time.

• Now checks with the CanTool hook for prop ownership meaing much better DarkRP support. (Thanks aStonedPenguoin)
  
• Reordered tests in the IsAllowedEnt() function to be more optimized.

• No more prints to clients about the completed welds, only to the server.

• You can now weld to specific body parts of a ragdoll when you look at it and select it. This does not work for auto-selecting.

• AllowAllEntities - Set to true by default, any server owners looking to limit welds please use the GitHub version.
  
• Selection Cleared notification.

• IsAllowedEnt() function - Made it more robust and easier to add to restrictions/exceptions to.
  
• Addon compatability disabled by default since all addons should work now.
