We always recommend updating to the latest version firmware as soon as possible. New firmware releases contain patches for known issues, improved performance for existing features, and sometimes entirely new features.
HoverflyPRO users, please note that PRO/GPS firmware is compatible with all versions of the PRO. If you have an older green board, you can still update to the latest firmware and enjoy all of the new features and enhancements.
Finally, please do NOT use firmware marked "Beta" or "Test" unless you have been directed to do so by the Hoverfly technical team. Both are likely to include incomplete or intentionally disabled features.
