 ## 21.1.0
+
+## 21.1.0 Features
+
+Features added between 20.10.0 to 21.1.0 include:
+* Berlin Network Upgrade: this release contains the activation blocks for Berlin across all supported testnets and the Ethereum mainnet. They are: 
+  * Ropsten 9_812_189 (10 Mar 2021)
+  * Goerli 4_460_644 (17 Mar 2021)
+  * Rinkeby 8_290_928 (24 Mar 2021)
+  * Ethereum 12_244_000 (14 Apr 2021)
+* Besu Launcher: Besu now has support for the [Quorum Mainnet Launcher](https://github.com/ConsenSys/quorum-mainnet-launcher) which makes it easy for users to configure and launch Besu on the Ethereum mainnet.
+* Bonsai Tries: A new database format which reduces storage requirements and improves performance for access to recent state. _Note: only full sync is currently supported._
+* Miner Data JSON-RPC: The `eth_getMinerDataByBlockHash` and `eth_getMinerDataByBlockNumber` endpoints return miner rewards and coinbase address for a given block. 
+* EIP-1898 support: [The EIP](https://eips.ethereum.org/EIPS/eip-1898) adds `blockHash` to JSON-RPC methods which accept a default block parameter.
+
+### Early Access Features
+* Bonsai Tries: A new database format which reduces storage requirements and improves performance for access to recent state. _Note: only full sync is currently supported._
+* QBFT: A new consensus algorithm to support interoperability with other Enterprise Ethereum Alliance compatible clients.
+
+### 21.1.0 Breaking Changes
+* `--skip-pow-validation-enabled` is now an error with `block import --format JSON`. This is because the JSON format doesn't include the nonce so the proof of work must be calculated.
+* `eth_call` will not return a JSON-RPC result if the call fails, but will return an error instead. If it was for a revert the revert reason will be included.
+* `eth_call` will not fail for account balance issues by default. An parameter `"strict": true` can be added to the call parameters (with `to` and `from`) to enforce balance checks.
+
+### Additions and Improvements
+* Added `besu_transaction_pool_transactions` to the reported metrics, counting the mempool size [\#1869](https://github.com/hyperledger/besu/pull/1869)
 * Added activation blocks for Berlin Network Upgrade [\#1929](https://github.com/hyperledger/besu/pull/1929)

 ### Bug Fixes
 * Fixed representation of access list for access list transactions in JSON-RPC results.

 ## 21.1.0-RC2
 ### Additions and Improvements
 * Support for the Berlin Network Upgrade, although the block number must be set manually with `--override-genesis-config=berlinBlock=<blocknumber>`. This is because the block numbers haven't been determined yet. The next release will include the number in the genesis file so it will support Berlin with no intervention.
