Important Notice: 5.0 BETA Firmware

You have selected 5.0 BETA firmware. BETA firmware is a pre-release version that includes new features and improvements, while rare, BETA firmware could contain bugs or usability issues. Please consider the following information before proceeding:

What is BETA Firmware?

  • Early Access: BETA firmware allows early access to new features that are not yet available in Stable Releases.
  • Testing and Feedback: It is intended for users who are willing to provide feedback and help identify any bugs or issues.
  • Potential Risks: There may be minor bugs, feature limitations, or performance issues.

Important Considerations

  • Are you comfortable troubleshooting and reporting any issues?
  • Do you understand the steps required to revert to a Stable Release if needed?
  • Do you have time to update your firmware more frequently, knowing that some updates may require a wireless reprogrammer?

Recommended Action

If you are not familiar with BETA testing, we recommend selecting the Stable Release version instead for the highest level of stability and support. For more details on our firmware release process, please review our complete guide here. If you have questions or need further assistance, please reach out to our support team.
