+# Node v1.33.1-rc1 / 2025-07-21
+This is the first release candidate of Lotus v1.33.1, which introduces performance improvements and operational enhancements. This release focuses on improving F3 subsystem performance, and enhancing CLI tools for better storage provider operations. Notable improvements include up to 6-10x performance gains in F3 power table calculations, ensuring that PreCommit and ProveCommit operations are aggregating to get optimal gas usage after FIP-100, and a enhanced sector management tool with CSV output support. These improvements collectively enhance the stability and efficiency of Lotus operations for both node operators and storage providers.

 # 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.
