Release 6.8.3

Release Notes -- AgOpenGPS 6.8.3

Final Release   Maintenance Mode   No new features   Bug fixes only



Version 6.8.3 marks the end of feature development for AgOpenGPS WinForms.
❌ New features
❌ Refactoring
✅ Critical bug fixes only

The torch has been passed.

Active development continues at:

AgValoniaGPS

Built with Avalonia UI -- Windows, Linux, macOS, Raspberry Pi

Caution

This is the last version of AgOpenGPS WinForms to include new features.
From this point forward this repository is in maintenance mode -- only critical bug fixes
will be accepted. No new features, no refactoring.

Active development has moved to AgValoniaGPS
(working title) -- a full rewrite using Avalonia UI targeting cross-platform support
(Windows, Linux, macOS, Android).

What's new in 6.8.3

AgShare – Cloud field loading

  • Fields linked to AgShare can now be automatically downloaded from the
    cloud     before opening, so you always work with the latest version.
    Applies to Open, Resume and Drive In.
  • New toggle in AgShare Settings to switch between Cloud Load (always
    fetch latest) and Local Only (existing behaviour).
  • AgShare Settings form redesigned with a cleaner layout.
  • Auto-Upload and Cloud Load buttons are now disabled when AgShare is
    not activated.
  • AgShare UI translations added for DE, NL, HU, CS, FR.

Settings

  • Nudge step size is now saved per Tool profile instead of globally,
    so each implement can have its own snap distance.
  • Switching to a different vehicle or tool profile now saves the current
    profile first    , preventing loss of unsaved changes.

Log Viewer

  • Log viewer opens significantly faster — no more line-by-line redraws.
  • Viewer auto-refreshes in realtime and scrolls to the latest entry.
  • Log file is now trimmed to the last 100 lines on startup.

Updater

  • Removed expired GitHub API token from the updater. The token was causing
    401 errors and required ongoing maintenance to keep up to date.

Bug fixes

  • Fixed ISOXML GuidancePattern ID assignment in TaskData export.
  • Normalized steer angle for inverted WAS in CSmartWAS.
  • Validated point counts and sort ISOXML boundaries by area.
  • Suppressed edge-case exception when a log file is locked by another
    process (e.g. OneDrive).

Release 6.8.2

Release Notes -- AgOpenGPS 6.8.2

Final Release   Maintenance Mode   No new features   Bug fixes only



Version 6.8.2 marks the end of feature development for AgOpenGPS WinForms.
❌ New features
❌ Refactoring
✅ Critical bug fixes only

The torch has been passed.

Active development continues at:

AgValoniaGPS

Built with Avalonia UI -- Windows, Linux, macOS, Raspberry Pi

Caution

This is the last version of AgOpenGPS WinForms to include new features.
From this point forward this repository is in maintenance mode -- only critical bug fixes
will be accepted. No new features, no refactoring.

Active development has moved to AgValoniaGPS
(working title) -- a full rewrite using Avalonia UI targeting cross-platform support
(Windows, Linux, macOS, Android).

What's New in 6.8.2

Features

Settings: Vehicle, Tool and Environment Profiles

Settings have been split into three independent profile types:

Profile Location Purpose
Vehicle VehicleProfiles/{name}.xml Steering, IMU, GPS, hardware brands
Tool ToolProfiles/{name}.xml Sections, tram, relay, Arduino Machine
Environment Environment/environment.xml Display, sound, window positions

This makes it possible to mix and match vehicles and tools freely -- e.g. switch the same
tractor between implements without reconfiguring everything.

Converter for existing profiles -- A dedicated conversion form (FormConvertProfiles) is
included to migrate old single-file profiles to the new format. The converter:

  • Reads all existing profiles from the legacy Vehicles/ directory.
  • Shows converted profiles in green; unconverted profiles in white.
  • Tool profile is optional -- select Vehicle only if you have no tool-specific settings.
  • Blocks duplicate names and shows a clear error dialog.
  • Stays open after conversion so you can process multiple profiles in one session.
  • Automatically migrates Environment settings on the first conversion (silent, one-time).

Profile management -- A unified profile management screen lets you rename and reset
Vehicle/Tool profiles. Renaming supports case-only changes (e.g. tractor -> Tractor).

Touch-friendly UI -- All profile toggle buttons are large and touch-optimised. On-screen
keyboard support is included in all text inputs.

Startup -- If no profile is found at startup, AgOpenGPS gives a clear message and guides
the user to load or create a profile.

ISOBUS Task Controller Integration

Full ISOBUS Task Controller (ISO 11783 TC) support has been added:

  • Task Controller is launched via AgIO and communicates with AgOpenGPS over the existing
    UDP/PGN channel.
  • Supports multiple CAN adapter drivers with automatic start.
  • Section control is handled by the TC, including correct reporting of 0 sections when no
    implement is connected -- helps verify that TC is running and talking to AgOpenGPS.
  • The current field name is sent to the Task Controller so TC logs are tied to the
    correct field.
  • TC-AgOpenGPS communication has been stabilised with process-data variables and logging
    to file.
  • All relevant PGN messages are documented in docs/pgn-protocol.md.

Auto-Update System

AgOpenGPS can now check for and install new releases automatically:

  • Checks GitHub releases for a newer version at startup.
  • Shows a user-friendly updater UI with release information.
  • Downloads and installs the update with rollback support (backup directories are preserved
    if rollback fails).
  • The updater module is independent of AgOpenGPS.Core so it can update even when the
    Core library changes between versions.

Smart WAS Auto-Calibration

A new Smart WAS (Wheel Angle Sensor) auto-calibration button has been added. Clicking it
zeroes the WAS from the current reading, simplifying initial setup and re-calibration in the
field without entering the full settings menu.

Import Tracks (from Field X to Field Y)

Tracks can now be imported from one field into another:

  • Short imported tracks (e.g. from ISO sources) now generate stable, complete curve guidance
    with an extended reference curve for offset and guideline calculations at track ends.
  • A guard prevents crashes when importing a single-point curve.
  • Twol track designations used internally by AgOpenGPS are excluded from the export,
    keeping imported tracks clean.
  • After import, the active track is automatically set as selected.

AgShare Improvements

  • Cloud availability is checked before uploading; duplicate uploads are blocked with a
    clear message in the Log Viewer.
  • Better error reporting for both upload and download failures.
  • The HttpClient is correctly re-created when the server URL or API key changes.
  • Internal refactor to a result-pattern and typed DTOs for all AgShare queries, improving
    reliability and error traceability.

Touch Drag Scrolling for Track Lists

Track lists now support touch drag scrolling, making it much easier to navigate long track
lists on tablet or touchscreen setups.

"Pop-Up AgIO on Warning" Setting

A new option in Advanced Settings automatically brings the AgIO window to the foreground
when a hardware warning is received, so warnings are never missed while AgOpenGPS is in
full-screen guidance mode.

AB Line Angle Display

The current AB line angle and its inverse (180 degree offset) are now displayed on the
guidance screen, giving the operator an at-a-glance reference for the pass direction.

New Languages

The following languages have been added:

  • Bulgarian
  • Croatian
  • Czech
  • Gujarati
  • Japanese
  • Romanian
  • Swedish

License Changed: GPL to Apache 2.0

The project license has been changed from GNU GPL to Apache License 2.0. This gives
integrators and downstream projects clearer terms for using, modifying, and distributing
AgOpenGPS components.

Improvements

Curve Guidance (CABCurve) -- Major Overhaul

The curve guidance engine has been substantially improved:

  • Point headings are now calculated from local coordinates rather than global, giving more
    accurate guidance on non-trivial curves.
  • The curve is hidden during recalculation to prevent visual flicker when switching tracks.
  • Cancellation checks added to extension loops to prevent the UI from freezing.
  • Side guidelines are capped at 3 for performance; the extension algorithm now uses a
    single 200 m anchor point instead of 300 interpolated points.
  • ResampleCurve, CalculateHeadings, and MakePointMinimumSpacing are now static,
    making the code easier to test.
  • U-Turn path is rebuilt automatically after a track nudge or reset.

Section Control at 10 Hz

Section control is now processed at a fixed 10 Hz instead of the main frame rate, giving
more consistent section switching regardless of GPU load.

Real Frame Time Display

The actual rendering frame time is now shown in the UI, replacing a synthetic counter.
This helps diagnose performance issues on slower hardware in the field.

UI Redesign: FormJob and FormDialog

  • FormJob has been redesigned with a modern button layout.
  • FormDialog has been redesigned and now supports a Severity level (info / warning /
    error), improving the visual clarity of system messages.

Tram Line Improvements

  • ReducePoints function added for tram track processing, improving performance on long
    boundaries.
  • Duplicate CreateBoundaryOuterTrack and CreateBoundaryInnerTrack code paths merged.

OpenGL / Rendering Performance

Multiple targeted performance improvements to the OpenGL wrapper (GLW):

  • Vertex3 replaced with Vertex2 where the Z coordinate was always 0.
  • GL.SetColor now accepts a byte array, reducing allocations.
  • ColorRgb replaced with ColorRgba throughout, removing a redundant type.
  • Viewport management refactored into a dedicated Viewport class.
  • SectionsVisual and FenceLineVisual encapsulate their own draw methods, removing
    direct dependencies on OpenTK internals.
  • VehicleDotVisual introduced to harmonise vehicle-dot rendering across forms.
  • BingMap separated into its own class; unused z_bingMap resource removed.
  • Texture2D and VertextArrayBase now implement IDisposable for correct release of
    unmanaged OpenGL resources.

Boundary Tool Improvements

  • Zoom and pan in the boundary tool form improved with better step behaviour.
  • GeoPolygon.RemoveSelfIntersections() added to prevent self-intersecting boundaries
    from causing calculation errors.
  • `GeoPolygon.RemoveCloseNeigh...

Release 6.8.1

Sadly we had a big bug in the section timers in version 6.8.0 we all missed.
This solves that problem. All sections run now at 10hz which raises the quality of section mapping turning on and off.

All other release notes can be found on the 6.8.0 release notes.
