+# v3 upgrade
+
+This upgrade moves the gravity module from consensus version 2 to 3.
+
+## Summary of changes
+
+* Bumps cosmos-sdk to v0.45.10 and ibc-go to v3.4.0
+* Bumps minor dependency versions
+* Fix signer set signature sorting inconsistency between orchestrator and chain when powers are equal
+* Add CompletedOutgoingTx store for marking transactions as executed
+* Refactor slashing logic and include CompletedOutgoingTx in unslashed tx getter
+* Add tx confirmation pruning 
+* Add event vote record pruning
+* Fix bug that iterated the entire key store when SetDelegateKeys was called
+* Refactor address lookups used in SetDelegateKeys to not require scanning entire list of validators
+* Remove MsgRequestBatchTx and handlers
+* Add missing Amino registrations
+* Fix minor CLI bugs
+* Improve and correct terminology in function names and comments
+* Update queries
