February 2025: Focused on API contract stability in safe-global/safe-client-gateway. Implemented OpenAPI schema corrections for multisig endpoints, aligning documentation with actual runtime data. Specifically updated schemas to reflect: transaction confirmations as an array of MultisigConfirmationDetails and multisig transaction details with an optional, nullable signature and signers as AddressInfo. These changes reduce integration issues for downstream clients and improve reliability for multisig workflows.
