Aug 1, 2025For 2025-08, delivered critical feature cleanups and security enhancements across Ledger Live (LedgerHQ/ledger-live). Key initiatives include removing the deprecated LiveQR account import across Desktop and mobile to reduce maintenance burden and security risk, and simplifying the build by dropping the qrloop alias from Vite. In parallel, modernized cryptography libraries across the monorepo to @noble/curves to standardize crypto operations, and added comprehensive SSL helper unit tests to bolster reliability. These changes reduce technical debt, tighten security, and create a cleaner, more maintainable codebase that supports faster iteration and fewer regressions.
