Dec 1, 2025December 2025: Implemented CI/CD improvements including a changeset validation workflow, flexible CI cache path handling, and release-management tweaks for LedgerHQ packages and live-mobile versioning. Stabilized staging by reverting the app identifier/bundle ID suffix to the previous style. Boosted test quality with a pnpm upgrade, removal of test delays, lint fixes, and updated code ownership to ensure mocks are hub-owned. Result: faster, more reliable releases and improved maintainability across the Ledger Live codebase for LedgerHQ/ledger-live.',

Aug 1, 2025August 2025: Ledger Live CI/DevOps enhancements delivering faster, more reliable builds and stronger quality signals across the repo. Key features delivered include iOS signing consolidation in CI by using environment-variable provisioning mappings and removing development certificate refresh logic, on-demand SonarQube scans via GitHub Actions, Turborepo-based CI optimization enabling parallelized tests and coverage for library code, and dependency alignment through Podfile.lock updates. In addition, Android CI stabilization (reduced Gradle workers, memory tuning, container-friendly JVM args) and desktop CI environment standardization (Linux image and dependencies) were implemented. CI workflow sequencing improvements fixed Turbo build order and ensured affected checks run before OK checks, improving reliability and resource usage. Overall, these changes reduce maintenance burden, shorten feedback loops, and reinforce build quality as Ledger Live continues to scale.
