1. Corrected the GetHashFunc implementation in EVM (#2998)
2. The transaction receipt and EVM log now bear correct index values (#2923)
3. When transaction is reverted, the corresponding logs are also removed (#3014)

v1.6.4

1. Fixed certain hardcode values in original babel service (#3038)
2. Correctly handle array in web3 request (#3050)
3. Added more tracing for slow API (#3057)
4. Fixed log query (with large block range) causing high memory usage (#3062)
5. Added gasFee info into GetActions() API (#3063)

v1.6.3

1. Implemented HTTP server to support web3.js API in iotex-core (this removes the need of intermediate Babel bridge/service)
2. Added eth_getStorageAt method
3. Instrumented tracing to measure timing on critical code path
4. Enabled EVM tracing to collect calling stacks inside EVM
5. Performance improvement of ActPool
6. Enabled log rotate
7. Corrected nested context usage in transaction processing loop

v1.6.2

1. fixed EVM calldata dump issue

v1.6.1

1. Separated the p2p network for Mainnet and Testnet, this reduces the network traffic interference and noise between 2 networks
2. Rectified transaction error message to be compatible with chainlink
3. API service added ReadContractStorage() interface

1. Added API tracing functionality, which enables measuring and visualizing the break-down of API call timing. We'll work on API performance improvement based on the observability this tool provides in future releases
2. Exposed gRPC health check point in the API server
3. Fixed contract read issue for certain smart contracts we've seen earlier
4. ioctl tool can export private key from HDWallet now
