Kaia v2.1.0 Released, Supporting MEV Auction and Multiple Optimizations

Kaia v2.1.0 is now live. This update focuses on supporting MEV Auction (KIP-249), improving API and storage performance, all without requiring a hard fork. The new version allows receiving BidTx, and external auction participants can transmit winners via websocket connection (auction namespace). It is recommended to enable websocket and restrict access permissions (firewall or allowlist is recommended). For full nodes, LevelDB now enables snappy compression by default. Users can reclaim disk space through chain database compression, though the process is time-consuming and increases I/O load. For archive nodes, an experimental FlatTrie feature has been added, enabling Erigon-style state layout, but it requires re-syncing and some functionalities are temporarily unavailable (e.g., eth_getProof, live pruning, rollback). Additionally, v2.1.0 introduces RocksDB support, RPC block parameters "safe" and "finalized," EIP-7702 validation mechanisms, as well as more granular compression controls and optimizations for performance and stability.
