Beta 79.3 is out, it makes quite a few improvements to the particle rendering for decoration editor and, a feature to prevent Lua scripts from freezing the game with infinite loops and a load more. Awesome new feature: Element searching, press 'e' on the keyboard to bring up a screen where you can search for elements, pressing enter will select the first result and you can left+right click as well.
Full list of changes, copied from the pull request I just made:
Fixes to fusion and adds oxygen fusion (needs Newtonian gravity)
Better live parts rendering in the deco editor and fixes some bugs with it (like the color picker)
Fixes EMP flash
Adds fast heat increase to PUMP/GPMP and makes GPMP default to on
fixes a crash with the lua console (tpt.setfpscap(1))
Prevents accidental infinite loops with lua
Updates the README.
Fixed a crash with spark reset (could create invalid elements if modified with console)
Prevented creation of disabled elements by using it's number instead of it's name.
Added the ability to create custom lua graphics functions (will update wiki with info later)
Made VOID more customizable (set it's ctype, it will only absorb that element. If it's tmp is 1, it will only not absorb it)
element search: press 'e' (not by me)
a few other very minor things probably
I've made a Lua script that add all secret elements to the regular menu :> much easier than using the new search function. nevertheless a useful new feature.
Element search is fxxking awesome!!!
But no good for tools, search HEAT result in nothing
Then the improvement comes to my mind is that, search also works for tools group and life group and walls
Search t, to, tool or anything alike will list all tools, so to life and walls
While search will not list element in these group individually, search heat will not list HEAT for example
Search group name will list all element in that group, maybe a new row? (match, related, group)
For example search liq you'll get 0 match, few related and liquid group
