solana-labs/solana v1.16.18 on GitHub

This is a stable release suitable for use on Mainnet Beta

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

Starting with v1.16.5, the TransactionStatus and AddressSignatures columns will be properly cleaned again. Earlier v1.16 releases had a bug that excluded those columns from blockstore cleanup. Without this cleanup, nodes using --enable-rpc-transaction-history could see excessive storage use. This has been fixed with #32548
Hidden CLI flag, --no-skip-initial-accounts-db-clean, was added to work around nodes with 128 GB of RAM that OOM at startup
Starting with v1.16.18, the mechanism for how node health (as reported by the getHealth RPC method) has been update. This update should address reliability concerns that operators have observed with using this method to monitor their node.
