Here is an overview of the new features and improvement in the latest Betaflight 3.4 firmware.
New Filter Default
Dynamic filter is now enabled by default, and Notch filters are disabled by default. New "stage 2" low-pass filters on both gyro and d term enabled instead of notch filters.
The Betaflight development team has stated that the defaults should now work great for any gyro rate up to 32kHz, which was not previously the case. Since the filtering algorithms have been changed, we recommend you re-tune your quadcopter and try out the defaults.
Using any TX with simulator via FC
You can use your quad (or a spare FC) to play simulator with any transmitter.
F7 Optimization
F7 chips now run much faster, allowing 32k rates to be used. It's been confirmed you can enable Accelerometer, Barometer, 32K/32K, and looptime settles at around 35%. Amazing!
Return to home feature
If you setup GPS on the quad, it can fly back to your launch position if you lose RC or video signal.

Other new features
- Added acro trainer mode, it's a special acro mode that refuses to tilt past a certain angle. You can practice flying acro without risking flipping upside down and flying into the ground
- Overhauled and improved filtering with a specific focus on improving defaults
- Added support for accessing SD card / onboard flash as USB mass storage device
- Added support for flight controller configuration via the Taranis with Crossfire installed
- Added support for filter based RC input smoothing
- Added throttle boost mode
- Added support for throttle limiting
- Added support for accelerated yaw spin recovery
- Added “paralyze” mode to be able to remotely power down a quadcopter.
- RSSI improvements for configuring RSSI range in the flight controller (use the “rssi_scale” and “rssi_offset” CLI options)
- New FC Board Support
- SPRACINGF7DUAL with dual gyro support
- Iterm Relax reduces overshoot on sharp filps and rolls
- Throttle boost provides a feed-forward mechanism on rapid throttle moves.
- Filter-based RC Smoothing reduces input latency compared to Interpolation method used in previous versions
