- Patch 1.3.2r4 - 19 September 2026
Trade Traders can now offer any tech and talent in the game, not just a small curated set (147 talents and 134 techs, up from 11 and 10). Resource and mercenary offers keep their share of the offers. Talents gained through trade now ignore your civ age's rune slot limit and building requirements.

Tech gained through trade ignores building requirements, but still needs its prerequisite tech. If an offer becomes unobtainable while your trader is away, the trader returns empty-handed and your gold is refunded, with a notification. The refund is subtracted from your gold spent on trade in Statistics. Buying an offer that is no longer available now shows "This offer is no longer available." Trading with a location you c…
