 # Node v1.33.0 / 2025-05-08
 The Lotus v1.33.0 release introduces experimental v2 APIs with F3 awareness, featuring a new TipSet selection mechanism that significantly enhances how applications interact with the Filecoin blockchain. This release candidate also adds F3-aware Ethereum APIs via the /v2 endpoint.  All of the /v2 APIs implement intelligent fallback mechanisms between F3 and Expected Consensus and are exposed through the Lotus Gateway.
