In one way, it is a small change in how Weave works. In another way, it is the most fundamental rewrite of Weave's functionality since Weave 1 -> Weave 2. The change is as follows:

• Anything you can put in the TEMPLATE.CFG can be modified in-game with #set and #clear.
  • Any numeric or color values can be modified with #give and #take as well.

This has a number of wide-reaching consequences:

• Whereas the source of truth for a particular Weave game used to be the .CFG file, now the entire .CFG file's contents are stored in the .SAV file and can be modified at-will. 
• This makes all element characters, colors, and a large majority of element functionality changeable on-the-fly.
• The ability to save the game, use torches, even the ability to pause the game, can all be rescinded and restored at any time. 
• All sidebar contents can be rewritten at any time (minus Quit).
  • This includes the theme colors.
• All in-game messages and sound effects can be modified during play.
• Numeric values affecting play can change over time:
  • The amount of damage the player takes
  • The amount of health or score a gem gives
  • The amount of ammo in a container
  • The effect duration of torches and energizers
  • The radius and shape of torchlight
  • The radius and shape of bomb explosions
  • The default behavior of enemies #PUT to the screen
  • The longevity of stars and bullets

The above are just examples. By manipulating the element table and game configuration, there is a substantial amount of flexibility in how the built-in elements and stats behave.

One caveat: Because this change is so fundamental, there may be kinks to work out. Still, as you will see when checking out the new section in WEAVEDMO (CFG MENU -> LIVE CFG CHANGES) many different scenarios and configurations have been tested already and behavior is as expected.
