+**Updates**
+
+* Added CPI rent prefunding support for Solana transactions in Gas Manager. Use `prefundRent: true` with `alchemy_requestFeePayer` when a sponsored transaction may create accounts through a cross-program invocation (CPI) and needs rent covered. [Learn more](https://www.alchemy.com/docs/wallets/api-reference/gas-manager-admin-api/gas-abstraction-api-endpoints/alchemy-request-fee-payer).
