March 2026: Key data/SDK enhancements for DeFi position tracking and risk analytics. Implemented Aave V4 integration and VNet updates in defisaver-positions-sdk (AaveV4View, APY data, premium calculation, spoke/hub address fixes), added frxUSD token support, and extended canBeBorrowed calculations to include borrowable state. Resolved critical edge cases including maxuint handling and comprehensive value handling fixes (after values, net APY, health factor, and type). Updated spoke naming and completed major versioning/maintenance tasks, including SDK releases and a stable non-Aave-v4 1.3.21 release. Business value: more accurate, timely position data, expanded asset coverage, safer borrowing assumptions, and streamlined release processes.
