What's new in this version:

- Improved: Configurator can now restart the Windows audio service and its dependent services to avoid the need for a reboot. This also allows to update Equalizer APO via setup without reboot.
- Fixed: Configuration Editor crashed on startup when analysis panel had been detached.
- Fixed: Notch filter in Configuration Editor was incorrectly set to "Fixed Q" instead of "Q factor" after load when the Q factor had been adjusted before.
