The Solana Foundation has requested an emergency upgrade for all Solana Testnet and Devnet Agave and Jito clients to v3.1.16 on January 11, 2026, at 11:36 UTC.

This release contains a critical set of patches that should be applied to staked and unstaked Solana Testnet and Devnet validators.

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.
