if you have a USB wifi device which uses the ath9k or ath9k_htc kernel module, you should postpone upgrading to any of the 5.7.6 kernels; or the device may not work when you next reboot - PCI devices do not seem to be affected by this bug
watch this bug report for further details
linux-libre and linux-libre-headers 5.7.6 have been pulled from the repos and replaced with 5.7.2; but other kernels remain at 5.7.6 - if you have already upgraded to one of the 5.7.6 kernels, and your wifi does not work, you will need to revert to the previous kernel:
# pacman -Syuu linux-libre
or boot a parabola LiveISO, mount your / partition, and install it with pacstrap:
# mount /dev/sdXN /mnt
# pacstrap /mnt linux-libre
IceWeasel-75.0-1.parabola2 brings an important update to the default configuration. We are relaxing the WebRTC privacy settings to allow Jitsi to function, bringing fully free video conferencing to parabola GNU/Linux-libre. The flip side of this change is that under certain circumstances this may be exploited in a way that the browser may leak local addresses in VPN connections. The browser extension 'uBlock Origin' provides a setting to prevent this from happening, and we are investigating ways to harden IceWeasel against such attacks.
In the meantime, to retain the old behaviour, set 'media.peerconnection.enabled' to 'false' in about ...
The zn_poly package prior to version 0.9.2-2 was missing a soname link. This has been fixed in 0.9.2-2, so the upgrade will need to overwrite the untracked files created by ldconfig. If you get an error
zn_poly: /usr/lib/libzn_poly-0.9.so exists in filesystem
when updating, use
pacman -Syu --overwrite usr/lib/libzn_poly-0.9.so
to perform the upgrade.
The nss and lib32-nss packages prior to version 3.51.1-1 were missing a soname link each. This has been fixed in 3.51.1-1, so the upgrade will need to overwrite the untracked files created by ldconfig. If you get any of these errors
nss: /usr/lib/p11-kit-trust.so exists in filesystem
lib32-nss: /usr/lib32/p11-kit-trust.so exists in filesystem
when updating, use
pacman -Syu --overwrite /usr/lib\*/p11-kit-trust.so
to perform the upgrade.
The hplip package prior to version 3.20.3-2.par1 was missing the compiled python modules. This has been fixed in 3.20.3-2.par1, so the upgrade will need to overwrite the untracked pyc files that were created. If you get errors such as these
hplip: /usr/share/hplip/base/__pycache__/__init__.cpython-38.pyc exists in filesystem
hplip: /usr/share/hplip/base/__pycache__/avahi.cpython-38.pyc exists in filesystem
hplip: /usr/share/hplip/base/__pycache__/codes.cpython-38.pyc exists in filesystem
...many more...
when updating, use
pacman -Suy --overwrite /usr/share/hplip/\*
to perform the upgrade.
