NOTE: New Multilingual Online Documentation starting with this release to be viewed or printed from online content you can get here: https://xcvario.com/docs/introduction/

RELEASE NOTE:
Compass heading has a bug and may show incorrect heading e.g. 180° instead of 360°, so also windcalculation is impacted. Fix in next release.

Full Changelog: 23.1129...24.0122

Release 23.1129

Minor Fixes, improvements and a new feature:

• Added new option for display test in 'Display Setup' menu, e.g. for measuring brightness (new feature)
• Darker grey color for small vario screen intermediate scale divisions: Improved readability (new)
• Change text in "AHRS Setup"->"AHRS Defaults" menu from 'Start' to 'Set Defaults': Improvement (since 23.0617)
• Fix bug with mean climb period incorrect displayed when vario unit is not set to default = m/s (epic bug)
• Fixed the hardcoded pin in dallas sensor class, code improvement (epic bug)
• Fix for error value propagation on MPU register read functions (epic bug)

Handbook unchanged, except new option "Display Test" in DISPLAY Setup, what will come with next release.

Release 23.0925

Small bugfix in startup screen

• Time corrected for AHRS g load swing in to correctly display 1.00 g in startup screen
• Audio defaults tuned for new speaker type
  • Equalizer off and no change on factory reset
  • Default volume now 25% instead of 10%

No change in handbook, small default adjustments see here will come with next release in handbook.

Release 23.0911

Minor code improvements and better accuracy for horizon at high angles of bank

• Rework and simplification of AHRS sensor fusion to best practice providing better stability in thermaling at higher angles of bank
• Tune gyro gating and minimum gyro trust parameters and add menu to set optimum defaults for "AHRS Parameters"
• Removed several obsolete AHRS parameters
• Build system update to improve for macOS build artifacts
• Fix variable names serial routing setup
• Clarifications and corrections in handbook

Release Note:

• The AHRS code changes bring benefit to wind calculation even with no AHRS license for horizon display
• Execute "AHRS Defaults" -> [Start] in "AHRS Setup" menu in order to catch up with optimum parameter settings, once changed or coming from an older release
• Due to a changed filter constant, AHRS sensor might show not show 1.00 g at startup (even correctly zeroed). Instead a couple of percent less, typically 0.94, 0.93 might be displayed. At next startup, it may show okay again. Its an issue of displaying the value too early at startup (before fully swung in). The device will properly operate even so. Issue fixed in release 23.0925 ff.

Release 23.0716

Several new features, improvements and fixes

• Simple horizon display as optional screen with AHRS feature enabled (new feature)
• Add separate setup option to adjust volume for g-load display (G-Load Display -> Alarm Volume) (new feature)
• Add QR code in OTA screen for network and OTA webpage as well (new feature)
• Option to disable SpeedtoFly switch and beside AutoSpeed, SpeedToFly switch to be merged also with Gyro or Flap driven mode (new feature)
• Improved horizon algorithm using dynamic gyro trust depending on load factor (improvement)
• Improved angle of bank stabilization with optimized fusion of g-load and airspeed/omega based angle of bank estimation (improvement)
• Relocate S2F Switch type setup to S2F Settings menu (improvement)
• Lower sound amplitude for frequencies below 400 Hz to improve speaker life (improvement)
• Fix issue with incorrect audio volume or tone style restoration in when alarm is triggerd twice in short time (epic bug)
• Fix green bow drawing, that might have happend a bit delayed in high system load (bug since 2023)
• Allow 88° instead of 80° for angle of bank (improvement)

Release 23.0526

New feature "audio equalizer", and minor fixes and improvements

• Introduce audio equalizer for different speakers internal 4 Ohms, 8 Ohm (default) or external SP600 (new feature)

  • Normally the default setting is okay 90% of gadgets have 8 Ohms speakers. If you have an external speaker like from xcvario shop
    (SP600) set to external. If volume sounds not equal at all frequencies, try the 4 Ohms setting.

• New check for GPS ground speed close to zero ( < 2 knots ) before periodic leveling of gyro drift on ground (improvement to recent feature)
• Re-introduce immediate restart on AHRS Autozero (new introduced bug in 2023)
• Fix issue in volume register calculation with increased center frequency at 700 Hz and Octaves setting 4 fold = max (epic bug)
• Ignore WebKitBoundaries tag to get "config restore" with recent Firefox version work again in OTA webpage (epic bug)
• Increase stack size in informObservers task to fix potential restart e.g. in entering AHRS key (epic bug)

New handbook in German and English attached.

Release 23.0508

• Ensure AHRS chip heating is off when in software update mode (epic)
• Fix an issue when Flap display is not enabled but subsequent settings were done (new bug since 2023)
• Fix Flap display that got enabled by default on factory reset, final solution (new bug since 2023)
