Testnet - v1.16.0

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

v1.16 removes solana-sys-tuner; previous users of solana-sys-tuner may need to perform manual tuning (see System Tuning instructions) and/or remove any references to solana-sys-tuner (such as in a systemd service file).

Changes

• remove solana-sys-tuner binary and all references (#31682)
• 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

Known Issues

• Custom account paths that are symlinks: #32037
  • workaround: Do not use symlinks for custom account paths; use the canonical path.
• Intermittent startup issues with solDeletePath: #32020
  • workaround: Restart again, or manually remove the <ledger>/snapshot/ and <ledger>/accounts/snapshot/ directories.
• --account-shrink-path <PATHS> causes validator to crash when adding bank snapshots: #32088
  • workaround: Remove --account-shrink-path option, restart
• solana-validator monitor and getHealth RPC calls (which use the same underlying mechanism) may falsely report that a node is behind. Some details in #31955 and #16957
  • workaround: Use solana catchup for now
• Nodes running with --enable-rpc-transaction-history will see ledger space grow beyond expected: #32548
