Conflux v2.0.3

Incompatible RPC Changes

• cfx_getLogs and eth_getLogs will no longer support the parameters limit and offset. They are not efficient and can be replaced by setting the block/epoch range instead.
• cfx_clientVersion will have include more information like web3_clientVersion in eSpace.
• fromEpoch will default to "latest_state" in cfx_getLogs.
• fromBlock will default to "latest" in eth_getLogs.

Improvements

Storage Improvements

• Avoid re-executing blocks if possible. This will accelerate the recovery process and reduce the disk usage if the node is restarted fast.

Configuration Improvements

• eSpace will be enabled for dev mode with a default configuration.
• Enable persit_tx_index for Archive nodes automatically.

Bug Fixes

• Fix a possible panic caused by inaccurate local timestamps.
