NOTABLE CHANGES

First in this release:

Ext2srv has been replaced by Ext4srv. Thanks sigrid!

We are now able to handle more USB audio, even ones
that do not offer standard 44.1kHz sample rate. (Sigrid!)

We got DNS over TLS support. Thanks moody!

WiFi support for Raspberry PI ported from Richard Miller. Thanks keegan!

I2C support and improved UART support for
MT7688. Thanks adventuresin9!

Vdiff, a graphical diff viewer got added! Thanks phil9!

Mixfs now allows switching between audio devices. Thanks cinap_lenrek!

Warning:

The behaviour of the IP stack has changed in this release.
Routes now bound to an interface and will get removed
when the interface goes away. And it is illegal to
add routes that cannot be assigned to an interface.

DOWNLOAD

Multiple installation media are provided for PC, Raspberry Pi, MNT
Reform, and QEMU. For PC, burn an .iso file to CD, or dd it directly
to USB media. For Raspberry Pi or MNT Reform, dd an .img file
directly to sdcard.

The pi.img file can be used for Raspberry Pi 1, 2, and 3. The pi3.img
file can be used for Raspberry Pi 3 and 4.

QEMU images are provided in QCOW2 format.
