+0.16.5
+==============
+
+- Updated docker base images to Debian Trixie.
+- By default reject secret hash type offers where the coin pair could use adaptor sig swap.
+  - override with "strict_swap_type" setting.
+- Verify follower's script chain lock refund tx sig.
+
+
+0.16.4
+==============
+
+- Security: Always require the initiate tx output index and value for secret hash swaps.
+  - Strengthens the 0.16.3 fix: the amount check can no longer be skipped when the output value is unavailable; the swap is now rejected (fails closed) instead of proceeding.
+- Security: Also double check the participate tx output amount for secret hash swaps.
+- Raise minimum Python version to 3.11.
