v1.23.3-rc2

This is the second release candidate for the upcoming feature release v1.23.3 of Lotus. This feature release includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

Highlights

• The Ethereum-like RPC exposed by Lotus is now compatible with EIP-1898: #10921
• The lotus-miner PieceReader now supports parallel reads: #10913
• The chain tipset cache is now based on a sharded mutex
• Added new environment variable LOTUS_EXEC_TRACE_CACHE_SIZE to configure execution trace cache size (filecoin-project/lotus#10585)
  • If unset, we default to caching 16 most recent execution traces. Storage Providers may want to set this to 0, while exchanges may want to crank it up.
