I have a problem with fixed wing autotune

I want to autotune a fixed wing airplane
However, there is a problem like the picture below, and the auto-tune button is not activated.
What should I do?

@jypbeck89 Which version of PX4 are you running? It appears that your PX4 version is too old for running autotuning

The QGC program uses the daily version, and the firmware version 1.13.2 is used.
Still getting the same error.
The aircraft frames I chose are Plane V-Tail and X-UAV Mini Talon.

@jypbeck89 You need a newer version, which you can’t install directly from QGC. You need to build it

What is the latest version that I can’t install directly?
Does that mean I have to program and use it myself?
Can you tell me what to do?

@jypbeck89 You can follow the instructions to build the firmware yourself: Building PX4 Software | PX4 User Guide

Otherwise you need to wait until the next release
