 All notable changes to this project will be documented in this file.
 
+## [0.9.0]
+
+### Added
+
+- Implemented a resultsCallback mechanism to persist email verification results on-chain.
+- Encoded email verification status (true or false) as 32-byte ABI-compliant binary data in the callback.
+- Wrote conditional callback-data to computed.json only when explicitly enabled by the requester.
+
+### Changed
+
+- Made the dApp backward-compatible with previous SDK versions by skipping callback-data when useCallback is not provided.
+- Improved email verification logic to reuse prior verification from the PoCo subgraph when available, reducing redundant Mailgun calls.
+
 ## [0.8.0]
