 # Node v1.33.1 / 2025-07-31
 This is the Lotus v1.33.1 release, 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.
