v1.1.20 is a hard fork release for BSC Chapel testnet.

The Chapel testnet is expected to have a scheduled hard fork upgrade named Planck at block height 28,196,022. The current block generation speed forecasts this to occur around 20th Mar 2023 at 01:30 AM (UTC). The Planck hardfork includes 2 BEPs to enhance network stability and security: BEP-171: Security Enhancement for Cross-Chain Module BEP-172: Network Stability Enhancement On Slash Occur

And the flag --diffsync is deprecated, since we have the fast node, which makes --diffsync not that useful. So we decide to remove it to keep the the sync logic simple. The flag has not been removed yet, but it only prints a warning message and do nothing. The flag could be totally removed in the following release.

The validators and full node operators on Chapel testnet should switch their software version to v1.1.20 before 20th Mar.
