Changes

Validator

Breaking

• --block-production-method central-scheduler is no longer supported. If passed, a warning is emitted and behavior will default to the greedy-scheduler implementation.
• scheduler-bindings version has been increased to 4. Connecting external schedulers must be updated.
• Validator now requires 26 ports, --dynamic-port-range must be at least 26 wide.

Deprecations

• Using minimal for --accounts-index-limit is now deprecated.
• --account-shrink-path is now deprecated.
• sbf-sdk.tar.bz2 is not included anymore in the Agave release tarball. The file will be made available in the new cargo-build-sbf repository.
• XDP support is no longer experimental. The --experimental-retransmit-xdp-interface, --experimental-retransmit-xdp-cpu-cores, and --experimental-retransmit-xdp-zero-copy flags have been deprecated. Use --xdp-interface, --xdp-cpu-cores, and --xdp-zero-copy instead. Behavior is unchanged: pass --xdp-cpu-cores to enable XDP on the specified cores.

Changes

4.0.0

RPC

Breaking

• --public-tpu-address and --public-tpu-forwards-address CLI arguments and setPublicTpuForwardsAddress, setPublicTpuAddress RPC methods now specify QUIC ports, not UDP.
• Blockstore PerfSamples column legacy format removed.
  • The PerfSamples column format was updated in agave v1.15 to write PerfSampleV2. The old format, PerfSampleV1, will no longer be supported for fallback reads as of v4.0.
• Blockstore transaction metadata column legacy format support removed.
  • The TransactionStatus, TransactionMemos, and AddressSignatures columns were updated in v1.18 to write a new key format. The old key format will no no longer be supported for fallback reads as of v4.0
• getSignaturesForAddress returns an error with code -32020 if the before or until signatures are not found, rather than a successful response with an empty array

Changes

• Added --enable-scheduler-bindings which binds an IPC server at <ledger-path>/scheduler_bindings.ipc for external schedulers to connect to.
• Added clientId field to each node in getClusterNodes response

Validator

Breaking

• Removed deprecated arguments
  • --accounts-db-clean-threads
  • --accounts-db-hash-threads
