Mandatory Update: Yes

Haber and Tycho(Cancun: BlobTx) hard fork will be enabled on BSC mainnet simultaneously, so this release also supports the Tycho hard fork, detail of Tycho hard fork may refer https://github.com/bnb-chain/bsc/releases/edit/v1.4.7

Description

Release v1.4.8 is a cut-in hard fork release for BSC Testnet and Mainnet, the HF name is: Haber, it only supports one BEP: BEP-381: Precompile for secp256r1 Curve Support

As there is strong demand for supporting of secp256r1 pre-compile contract, we decide to move it faster.
And BSC would use address 0x100, which is same as other major chains to make it easier for developers.
Developers may refer this code on how to use this pre-compile contract: https://github.com/getclave/clave-contracts/blob/master/contracts/helpers/VerifierCaller.sol

The target Haber hard fork time will be:

• Testnet: 2024-05-29 06:07:00 AM UTC
• Mainnet: 2024-06-20 06:05:00 AM UTC
