Software update: Betaflight 4.2.8

Flight controller software is used to control drones or airplanes. Open source examples include Cleanflight, Ardupilot, Inav, and Betaflight. The latter includes support for dshot, multishot and oneshot engine protocols, STM32, F4 and F7 processors, telemetry protocols, and OLED displays. Earlier STM32 processors, such as the F1 and F3, are supported by older Betaflight releases. The developers have released version 4.2.8 with the following list of changes:

Version 4.2.8

Important: There is a bug in the previous release (4.2.7) that potentially causes unresponsiveness of the flight controller on power up. If you experience this on your flight controller, please update to this release to fix the issue.

Version 4.2.7

Safety Improvements:

• fixed bugs in the use of baro_sample_count causing potential runaway ascent (#10472, #10481).

Fixes:

• fixed missing BLHeli32 hardware version (#10290);
• fixed compiler warning when building the SITL target (#10363);
• fixed problem causing high error rates with bidirectional Dshot on H7 (#10383);
• fixed problem of getting stuck in the CMS menu when invoking multiple times with SRXL and CRSF (#10448);
• fixed compilation errors in the AK8975 magnetometer driver (#10464, #10477);
• fixed bug causing a lockup when setting ibata_scale to 0 (#10471);
• fixed validation for minimum and maximum cell voltage (#10473);
• fixed bug in displayport code leading to the potential for UART1 to be flooded with OSD messages (#10489, #10490).

Target Updates:

• added more features to target IFLIGHT_H743_AIO(#10451);
• added the AK8975 magnetometer driver to the Unified Targets (#10468).

Version 4.2.6

Fixes:

• added missing CLI parameter osd_warn_rssi_dbm (#10405);
• fixed problem causing lockups when sending blocking Dshot commands with bitbanged Dshot enabled (#10406);
• fixed incorrect limits for range checks for RACEFLIGHT and KISS rates (#10429);
• fixed bug causing voltage sag compensation to be applied in crash flip mode (#10442).

Target Updates:

• added support for additional flash chips to IFLIGHT_H743_AIO target (#10419).
