iNav 2.1 RC out - Bye bye F3 boards

[Coyote]

If you use the popular F3 boards like the Omnibus then 2.0 is the last release of iNav you can use with it.

Now 2.1 is out only higher boards supported now.

The wiki shows that 2.1 will the be the last release that fully supports the F3.

Important Notes
INAV 2.1 is the last release of INAV that fully supports F3 and especially Omnibus F3 boards. Due to the lack of flash and RAM, future versions of INAV will either remove functions on F3 or not support those boards at all. STM32F3 are strongly discouraged for new builds and existing builds should be upgraded to F7 boards
