+## [2.0.0](https://github.com/band-ai/band-sdk-python/compare/band-sdk-v1.6.0...band-sdk-v2.0.0) (2026-08-23)
+
+
+### ⚠ BREAKING CHANGES
+
+* ParlantAdapter(server=, parlant_agent=) is no longer required (both are now optional, keyword-only escape hatches), and the dead additional_tools parameter is removed — it was stored but never bridged into Parlant tool-calling (INT-1167 tracks the real bridge).
