The Solana Foundation has requested an emergency upgrade for all Solana Mainnet, Devnet and Testnet Agave and Jito clients that include a critical security patch.

No downtime is expected, but customers may experience brief connection interruptions and a small number of HTTP 503 responses as services restart and resynchronize with the cluster.
