-## [1.1.5] - 2025-09-06
+## [1.1.6] - 2024-09-09
+  - Optimize handling of source transaction inputs. Avoid mocking up entire transaction when adding source inputs.
+  - Minor alignment in ECIES helper function
+
+### Changed
+  - `SetSourceTxFromOutput` changed to be `SetSourceTxOutput`
+  - Default behavior of `EncryptSingle` uses ephemeral key. Updated test.
+
+## [1.1.5] - 2024-09-06
   - Add test for ephemeral private key in electrum encrypt ecies
   - Add support for compression for backward compatibility and alignment with ts
