What's new in this version:

- Fixed: Bluetooth devices on Windows 11 often did not work when multiple devices were combined (headphones and hands-free). In this case, installation as SFX/MFX is now used by default as EFX does not work.
- Fixed: Reimplemented Voicemeeter integration (based on official examples) to fix stuttering issues.
- Improved: On Windows 8.1 and newer, installation as SFX/EFX is now the default. This should remove the need to use the troubleshooting options for most users.
- Improved: Updated to Visual Studio 2019 and Qt 5.15.2. Running Equalizer APO requires Universal CRT now, which means that Windows versions before 10 may need additional Windows updates or the Visual C++ Redistributable for Visual Studio 2015 - 2019 needs to be installed (installer provides assistance).
