PX4-Autopilot Main Release Notes

<script setup> import { useData } from 'vitepress' const { site } = useData(); </script>

This page is on a release branch, and hence probably out of date. See the latest version.

This contains changes to the PX4 main branch that are not included in the next release (PX4 v1.18).

::: warning PX4 v1.18 is in beta testing. Update these notes with features that are going to be in main (PX4 v1.19 or later) but not the PX4 v1.18 release. :::

Read Before Upgrading

Please continue reading for upgrade instructions.

Major Changes

  • TBD

Upgrade Guide

  • COM_ARM_TRAFF has been replaced by COM_TRAFF_AVOID. The old value 3 ("enforce for mission modes only") is migrated to COM_TRAFF_AVOID=2, which blocks arming in all modes, not just mission modes. If you relied on being able to arm manually with traffic detected, set COM_TRAFF_AVOID=1 (warning only) instead.
