v0.12.0

on GitHub

Breaking Changes

• Upgraded to v0.12.1 of the beacon chain spec. This is compatible with the Altona and Onyx testnets. For the Witti testnet use the 0.11.5 release.
• --metrics-host-whitelist CLI option has been renamed --metrics-host-allowlist
• --rest-api-host-whitelist CLI option has been renamed --rest-api-host-allowlist
• The Rest interface is now correctly set from --rest-api-interface, so will need to be correctly configured to ensure
  that hosts specified in the --rest-api-host-allowlist are able to access that interface. Note that the default is to listen on localhost only.
• --rest-api-enabled is now correctly used to determine whether to start the rest api. Ensure it is set if using the rest api. Note that the default is disabled.

Additions and Improvements

• Support beacon chain spec v0.12.1.
• The --network option now includes support for altona and onyx. The default network is now altona
• Disk space requirements have been very significantly reduced, particularly when using archive storage mode
  • Finalized states are now stored in a separate database to non-finalized data.
    CLI options to store these under different directories are not yet available but will be considered in the future
  • Snapshots of finalized states are stored periodically. The data-storage-archive-frequency option controls how frequent these snapshots are.
    More frequent snapshots result in greater disk usage but improve the performance of API requests that access finalized state.
  • Due to the way regenerated states are cached, iterating through slots in increasing order is significantly faster than iterating in decreasing order
• Teku now exposes RocksDB metrics to prometheus
• The genesis state root, block root and time are now printed at startup
• The time to genesis being reached is now output every 10 minutes, so that it's visibly apparent that teku is still running
• Requests made to ETH1 nodes now include the Teku version as the user agent
• Unstable options can now be listed with teku -X. These options may be changed at any time without warning and are generally not required, but can be useful in some situations.
• Added a bash/zsh autocomplete script for Teku options and subcommands
• Reduced memory usage of state caches
• The list of validators being run is now printed to the console instead of just the log file

Bug Fixes

• Fixed a very common error message while handling received attestations from peers
• Reduced log level of Connection reset log messages from NoiseXXSecureChannel.
• Fixed an issue where the last ETH1 block with deposits was processed twice when Teku was restarted pre-genesis. This resulted in an incorrect genesis state being generated.
• Update the private key message at startup to more clearly indicate it is referring to the ENR.
• The --rest-api-interface configuration attribute is now set on the HTTP server, it no longer listens on all interfaces.
• The --rest-api-enabled flag will determine whether the http server actually starts and binds to a port now.
• Fixed minor memory leak in storage
• Fixed potential crashes in RocksDB while shutting down Teku.
• Fixed an incompatibility with other clients due to Teku incorrectly expecting a length prefix for metadata requests
• When no advertised IP is specified and the p2p-interface is set to 0.0.0.0 or some other "any local" address,
  Teku will now resolve the IP for localhost instead of using the "any local" address in it's initial ENR.

Known Issues

• Validator may produce attestations in the incorrect slot or committee resulting in Produced invalid attestation messages (#2179)
