1.37 was purely bug fixing from what I remember, and the only patch after it. It's possible they did something like cap an AOE disable as part of "entity file fixes", but they did the patch to backport the desync fix done for rebellion, not to make gameplay changes.
- Backported desync fix from Sins: Rebellion to fix longstanding desync issue related to random streams.
- Backported entity file fixes from Sins: Rebellion.
- Many punctuation fixes to various diplomacy related strings.
