Addition of TNT
Addition of IGNC ignition cord
Addition of ELECtrons
MAJOR upgrades to Lua interface (short of making brand new elements, complete editing of existing elements can now be done in Lua, so everyone can make their own "mini mod" without compiling a single line of C code and without hex-editing powder.exe).

For example, put this in a file called "autorun.lua" then run TPT and you'll see that DMND is now readily eroded from being struck by ELEC.

math.randomseed(os.time())
function test_update(i, x, y, s, n)
if tpt.get_property("type",x+math.random(-4,4),y+math.random(-4,4)) == tpt.el.elec.id then
tpt.delete(i)
end
end
tpt.element_func(test_update, tpt.el.dmnd.id)
