solana-labs/solana v1.16.5 on GitHub

This is a Testnet release. It is not recommended for Mainnet Beta

v1.16 removes solana-sys-tuner. For manual tuning please see these System Tuning instructions

The calculate_accounts_hash_cache directory under ledger/ has been renamed. After upgrading to v1.16, the ledger/calculate_accounts_hash_cache/ directory can be removed. #29734
In previous v1.16 releases, the TransactionStatus and AddressSignatures columns were not properly cleaned. This could have resulted in excessive storage use for nodes running with --enable-rpc-transaction-history. This has been fixed with #32548
