Worked on maintaining stability for the LedgerHQ/device-sdk-ts repository by addressing issues introduced during a Next.js upgrade. Focused on risk mitigation, the developer reverted Next.js from version 15.1.6 back to 14.2.15, restoring a previously stable baseline and preventing potential production incidents. The rollback was validated through continuous integration and regression checks, ensuring the stack’s reliability. All changes were documented in release notes and change history to support future governance and traceability. The work emphasized dependency management and version control, utilizing YAML for configuration updates, and demonstrated a methodical approach to maintaining software stability over the course of the month.
