Ports PsiOmegaDelta's port of integrated circuits, which has several improvements in code quality.
Ports a few small things like the weakref datum and some macros.
A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
Cost for various spells and equipment adjusted greatly. In general, things are cheaper, and everything should now be in multiples of 25, so no points are wasted.
The default jumpsuit for Technomancers is now heavily insulated, protecting them from tasers, batons, and perhaps unfortunate lightning strikes.
Instability between 31 and 50 made less harsh.
Wards made with a scepter of enhancement will break the cloak of anyone invisible that it can see.
Fire aura buffed, increased rate of heating as well as temperature cap for both non-scepter and scepter effects.
Reflect spell made more forgiving for the Technomancer, lasting longer before expiring.
Projectile spells should be able to hit people more reliably.
