Upgrades & Breaking Changes

  • Because 4.5.0 introduces a key management variable in the backend, users should also update to the most recent version of the Strato Getting Started repository to avoid potential conflicts.
  • Upgrading to 4.5.0 requires additional support for users who have created private chains and private chain transactions. Please contact us for additional information if you are using a version below 4.5.0 with private chains employed and seek to update your network.
