+## 21.1.0
+* Added activation blocks for Berlin Network Upgrade [\#1929](https://github.com/hyperledger/besu/pull/1929)
+
 ## 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. [\#1898](https://github.com/hyperledger/besu/pull/1898)
