New features and enhancements

Aptos Frameworks

• AIP-49 – Add transaction support for SECP256K1 ECDSA. This uses feature flag: single_sender_authenticator. This reuses the same feature flag as AIP-55.
• AIP-52 – Automatically create user accounts when said account is sponsored by another fee paying account. This uses feature flag: sponsored_automatic_account_creation
• AIP-53 – Make it so that a transaction sent by a client need not know who the fee payer is when signing the transaction. This uses feature flag: fee_payer_account_optional
• AIP-55 – Generalize transaction authentication making it easier to add new transaction authenticators used across single singer, multi-agent, and fee payer transactions. It also adds support for generalized K-of-N multikey accounts, previously only available to ED22519. This uses feature flag: single_sender_authenticator

Move Language and VM

• Limits the maximum identifier length in Move modules from 65535 to 255, which is used in the serializer and deserializer of the Move binary format. This uses feature flag: limit_max_identifier_length
