Release notes

This release is mandatory for all users operating on OP Stack chains. It includes a fix for an issue discovered during Base archive sync. Additionally, this version is recommended for node operators who use older CPUs on Sepolia, Holesky, or Chiado.

Major highlights

Fix for the Base Mainnet

Addressed the issue #8361 when sync was failing on processing blocks with invalid SecP256r1 precompile parameters.

Fix for the BLS precompile issue on older hardware

Fixed the issue with BLS precompile, which caused a crash on some CPUs that don't support modern ISA extensions like Intel ADX. The current version restores support for older hardware by disabling certain CPU-specific optimizations.
