Bor v2.4.0-beta is a major release containing changes for Madhugiri Hardfork on Amoy along with several improvements and bug fixes.
Madhugiri Hardfork enables the following PIPs/EIPs
- PIP-74: Canonical Inclusion of state-sync (bridge) transactions in block body.
 - Parameterise block producer time (PIP to be added soon)
 - EIP-7883: ModExp Gas Cost Increase
