QGroundControl's v5.1.5 patch restores mission commands lost to a translation bug.

mavlinkdrone-opsrelease-hardeningardupilotpx4
◆Current state
QGroundControl v5.1 went stable on August 20 after two release candidates, with a corrected HUD pitch direction as the headline behavior change. Patches followed: v5.1.4 with nineteen fixes on August 30, and v5.1.5 on October 1, which restores mission commands lost to broken enum translations, fixes ArduPilot takeoff when already armed, and repairs log downloads and camera controls. A v5.2 development base was tagged on September 19.
◆Where it's heading
The v5.1 line is in repair mode with fixes on a monthly rhythm, while v5.2 work has opened in daily builds. No v5.2 features are described in the feed yet.
◆Prediction
Another v5.1 patch is likely before any v5.2 release candidate; the v5.2 schedule is unclear.

    v5.1.5: lost mission commands restored, ArduPilot takeoff fix

    v5.1.5 restores mission commands lost to broken enum translations, starts ArduPilot takeoff when the vehicle is already armed, and fixes log downloads, camera timelapse and keyboard focus. The mission fix matters most for anyone planning flights in an affected language.

    v5.2 development base tagged

    A tag marking the base for v5.2 daily builds, with no notes. It confirms the next line is open while v5.1 takes patches.

    v5.1.4 patch: 19 fixes, PX4 v1.17 gripper detection

    The first patch on the v5.1 stable line, carrying nineteen fixes and no new features. Most repair user-visible behaviour — the Land tool inserting RTL for rovers, Save as... returning to mobile, hardened H.265 recording — while gripper detection via PD_GRIPPER_TYPE extends support to PX4 v1.17. It is the clearest sign yet that v5.1 is in stabilisation rather than expansion.

    v5.1 goes stable; HUD pitch indicator direction corrected

    v5.1 reaches stable after two release candidates. The notes carry no change list of their own, deferring to the What's New page, but they do foreground one operator-facing change: the HUD pitch indicator now moves down when the nose pitches down, matching the roll convention and reversing long-standing behaviour.

    v5.1 RC2: GPS reassembly, airspeed, and FTP fixes

    The second v5.1 candidate is where the line's substantive fixes landed — GPS_RTCM_DATA fragmentation for MAVLink reassembly, PX4 airspeed calibration, and an FTP fallback when a vehicle NAKs list-with-time. It also adds a destroyQmlApplicationEngine plugin hook and restores the macOS universal binary default, continuing the packaging work visible across the v5.0 patches.

    v5.1 first release candidate

    The opening v5.1 candidate ships with boilerplate notes only — installation pointers and an issue-reporting request, with all user-facing detail deferred to the What's New page. It marks the start of the cycle rather than describing any of its content.
