 # Changelog
 
-## 23.1.0-RC2
+## 23.1.1-RC1
+Besu 23.1.1-RC is a required update only for users who want to test Shanghai on Sepolia.
+
+### Additions and Improvements
+- Add implementation for engine_exchangeCapabilities [#4997](https://github.com/hyperledger/besu/pull/4997)
+- Add implementation for engine_getPayloadBodiesByRangeV1 and engine_getPayloadBodiesByHashV1 [#4980](https://github.com/hyperledger/besu/pull/4980)
+- If a PoS block creation repetition takes less than a configurable duration, then waits before next repetition [#5048](https://github.com/hyperledger/besu/pull/5048)
+- Fix engine_getPayloadV2 block value calculation [#5040](https://github.com/hyperledger/besu/issues/5040)
+- Add support for Shanghai in Sepolia [#5088](https://github.com/hyperledger/besu/pull/5088)
+
+## 23.1.0
+Besu 23.1.0 is a recommended update for Mainnet users. Thank you all for your patience as we crafted this quarterly release.
+
+This is a rather large release with some breaking changes, so please be sure to read these notes carefully before you upgrade any Besu instances. We are including a move to Java 17 LTS. To build and run Besu, please make sure you have Java 17 on the host machine. Additionally, there are a host of spec compliance changes that change existing formats, so please check the specific RPC updates. Lastly, this release formalizes a deprecation notice for GoQuorum privacy modes and IBFT1.0 in Besu. These will be removed in the 23.4 series, unless otherwise stated.
+
+From the improvements and fixes side, we have a host of execution performance improvements and fixes for defects with bonsai storage. We have also included an error detection and auto-heal capability for nodes that encounter state issues. This should keep nodes online and validating that may have previously required a resync.
+
+One final note. 23.1.0 is not a Shanghai ready release. If you intend to test Besu on the long-lived testnets like Zhejiang, please follow the instructions here. We will have more to share on our official Shanghai releases soon.
 
 ### Breaking Changes
 - Change JsonRpc http service to return the error -32602 (Invalid params) with a 200 http status code
 - Besu requires minimum Java 17 and up to build and run [#3320](https://github.com/hyperledger/besu/issues/3320)
-- PKCS11 with nss module (PKCS11 based HSM can be used in DevP2P TLS and QBFT PKI) does not work with RSA keys 
-in Java 17. SoftHSM is tested manually and working. (Other PKCS11 HSM are not tested). The relevant unit and acceptance

+in Java 17. SoftHSM is tested manually and working. (Other PKCS11 HSM are not tested). The relevant unit and acceptance
 tests are updated to use EC private keys instead of RSA keys.
 - Change eth_feeHistory parameter `blockCount` to accept hexadecimal string (was accepting plain integer) [#5047](https://github.com/hyperledger/besu/pull/5047)
+- Default configurations for the deprecated Ropsten, Kiln, Shandong, and Astor networks have been removed from the CLI network list. These networks can currently be accessed but will require a user-provided genesis configuration. [#4869](https://github.com/hyperledger/besu/pull/4869)
+- GoQuorum-compatible privacy is deprecated and will be removed in 23.4
+- IBFT 1.0 is deprecated and will be removed in 23.4
+- Optimize SSTORE Operation execution time (memoize current and original value) [#4836](https://github.com/hyperledger/besu/pull/4836)
