Binance Smart Chain Mainnet will undergo the Luban hard fork in a few weeks on June 11th.

Luban hard fork to include 3 BEPs:
-- BEP-126: Introduce Fast Finality Mechanism.
-- BEP-174: Introduce BSC Extension Protocol.

Let’s look into them in detail:
BEP-126 aims to reduce the confirmation time of BSC transactions by introducing a voting mechanism among validators.
BEP-174 introduces a new governance proposal type to manage the set of whitelisted Relayers.
A Relayer is a service that facilitates cross-chain communication and data sharing among different blockchains by relaying messages and transactions between them.
BEP-221 introduces a new pre-compiled contract to authorize the CometBFT blocks.
CometBFT is a light block validation protocol used by the BSC Extension Protocol to verify the block headers of other chains.
