+## v3.0.0-rc1 : Full Refactor and ConwayEra Support
+
+### Changes on kuber-server
+- Add new chain-query api-endpoints.
+    * **GET** /api/v3/protocol-params
+    * **GET** /api/v3/chain-point
+    * **GET** /api/v3/utxo
+    * **GET** /api/v3/system-start
+    * **GET** /api/v3/genesis-params
+- Update default healthcheck url in docker image. (`/api/v3/chain-point` is used for healthcheck )
+- Server starts by querying NodeEra and enables fields based on `BabbageEra` or `ConwayEra`
+- TxBuilder json now supports following new fields.
+    * **$.proposal[s]** Conway Era Governance proposals.
+    * **$.votes[s]** Conway Era votes.
+    * **$.certificate[s]** Registration and dregistration certs only for Conway era. (Not available when node is running in babbage era).
+
+
+#### Known Issues:
+- If node is at Babbage era when kuber-server starts, after node reaches Conway era, restart is required  to enable Conway features.
+- `$.validtyStart` is broken and is ignored.
+
+
+### Changes on Kontract-example [WIP]
+- Introduced new package to showcase usage of `Kontract`
+
+
+### Changes on lib:kuber
+- Update code comments for better haddock docs generation
+- Implement both `ToJson` and `FromJson` for all the entities used in api
+- Reorganize code and  introduction of  `Kontact` for offchain code.
+- Support For ConwayEra **[BREAKING change ]**
+- `TxBuilder`  is now parametrized on `era` suppporting `Babbage` and `Conway` eras, with `IsTxBuilderEra` constraint.
+- Kuber Offchain code required Local Node Socket. **WIP** support running kuber code by connecting to kuber server
+- Remove `ChainConnectInfo`and related classes.  Instead, use `LocalNodeConnectInfo CardanoMode` directly.
