Release 22.0701

Straight and Circling wind calculation rework

Example of a straight wind and circling wind comparison over the day. Wind was expected with 20 to 25 km/h 120° turning to 150° (7.2. https://www.weglide.org/flight/178203) according to the forecast.

Handbook (just the Straight wind menu) rework, will be done asap.

Release 22.0515

New polars, more precise straight wind calculation, less flickering needle and two fixes

• Added new polars for ASH25 pure glider and LS6 neo
• Sideslip estimation feature added based on lateral acceleration

Release 22.0508

Improvements and minor fixes in the area of center-aid, compass, wind and gear warning

• New feature to acknowledge an active gear warning by rotary press (for 5 minutes)

• Fix straight wind average setup which could go beyond the internal limits
• Overwrite stored values in thermal aid for same direction from last circle also by negative climb
• Draw airplane symbol in center aid also when wind calculation is switched off
• Rolling altimeter quantization of 1 replaced by 2 for more smooth rolling direction indication
• Lower compass damping in default settings (1s, before 3s)
• Compass calibration checks for ~2 sec stable values before taking over (more accuracy, no false green)
• Consider peak values of current thermal for center aid for better dynamic
• Support for software downgrade even new feature has been selected from a newer release (fall back to max possible selection in setup)
• Use last QNH setup instead of 1013.25 on next startup when airfield elevation is not set (-1)
• Lower memory consumption by bitfields and datatypes with smaller footprints
• Avoid clipping left upper corner of "s" in s-net text display in vario screen

Release 22.0425

Flicker free needle, configuration backup and restore, and a minor fix

• New feature to backup and restore XCVario configuration on a mobile device
