Ground control station for MAVLink drones and autonomous vehicles

The v5.1 line is stable and already patching, with repair work far outpacing new surface.

◆Current state
QGroundControl closed out its v5.1 cycle on 20 August and shipped the first patch on top of it ten days later. The release train ran RC1 in late July, RC2 in mid-August, then stable, then v5.1.4 — a compressed cadence compared with the v5.0 line, where consecutive stable patches were months apart. The headline behavioral change in the line is the corrected HUD pitch indicator direction, which the project flags prominently because it inverts what existing operators are used to seeing.
◆Where it's heading
The centre of gravity has moved from adding surface to hardening what v5.1 already exposes. v5.1.4 is nineteen entries long and every one of them is a fix: plan view routing, link teardown, delayed H.265 recording, settings navigation, joystick update rate, translation placeholders. Alongside that, the project keeps investing in build and distribution plumbing — signed and notarized Mac bundles, universal binary defaults, a plugin hook for engine teardown — which suggests packaging reliability is being treated as product work rather than infrastructure.
◆Prediction
Expect further v5.1.x patches on a short cadence, still weighted toward fixes rather than features, with continued autopilot-compatibility work as PX4 v1.17 lands in the field.

    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.

    Mac bundles signed and notarized; crash fixes

    The last v5.0 patch before the v5.1 cycle opened, and the point where distribution became a visible workstream: Mac bundles are signed, notarized and stapled, removing an install-time obstacle for that platform. The remainder is crash and permission repair, including Android SD card access on API 30 and above.

    Bug-fix patch across analyze view, plan, and gimbal UI

    A maintenance patch on the v5.0 stable branch: analyze view command sending, a telemetry colour picker bug, a crash on loading an absent parameter, and camera backports. Nothing here changes what the station can do, but it fits the pattern of the project keeping its stable branch serviced while the next line is in development.
