This is all TEC related.

Phase inhibitors:

In SINS 1.12, the phase inhibitors have a stacking effect (700% for 1, 1400% for 2 etc etc). In entrenchment they do not stack.

Interface change?

The shipyard tabs used to be Frigates, Cruiser, then Capitol ships on the lower right. Now it is Capitol ships, Frigates then Cruisers. Was this an intended change? Easy to adjust yes, but does it change back in multiplayer if you play a non-entrenchment opponent? (I have not tested - sorry). It seemed to be more intutive when you read left to right in the older arrangement of the least powerful (and sooner available) on the left moving up to the more powerful (later availability) ships on the right.

Appearance:

A SB with a trade port never shows any trade ships coming or going. The trade value does not appear in the total income window (when you hover of credits and you see all sources of income).
