 ### Changed
 
 - (`loadtest`): `zksync_fee` has been moved to `[main_wallet]` section from the `[network]` section.
+- A special balancer for FeeTicker was replaced with a generic balancer.
+- (`eth_client`): `web3` field was made private in `ETHDirectClient`. `testkit` and `loadtest` don't use it directly
+  now.
 - (`api_server`): Make `submit_txs_batch` send only one signature request.
+- Fast withdrawals now can trigger aggregated block execution.
 
 ### Added
 
 - (`loadtest`): Added `zksync_fee` option into the `[scenario]` section to set fee for each scenario individually, added
   `fee_token` option into the `[main_wallet]` section to set token that is used to pay fees for the main wallet
   operations.
+- (`eth_client`): Added `get_tx`, `create_contract` methods to `EthereumGateway`, `get_web3_transport` method to
+  ETHDirectClient.
+- (`api_server`): Support for accounts that don't have to pay fees (e.g. network service accounts) was added.
+- Added `BlockMetadata` structure and corresponding table to track block data that is not related to protocol.
 
 ### Fixed
 
+- (`zksync_api`): Internal error with tokens not listed on CoinGecko.
+- Fix wrong block info cache behavior in the `api_server`.
