Conversation
- Note now references Fusaka (Beta v4.4) instead of Pectra (Beta v4) - Remove BLAKE2f and RIPEMD-160 from unsupported precompiles (supported since Osaka) - Update MODEXP argument bound to 1024 bytes (EIP-7823) - Drop the 0x01-0x09 range from the precompile-recipient restriction (the Osaka precompile set is larger); the restriction itself still applies - Reword the dated 'available with Linea Beta v4' beacon-root phrasing Signed-off-by: Othryades <Othryades@users.noreply.github.com>
