The libxml2 package prior to version 2.9.12-6 was missing the compiled python modules. This has been fixed in 2.9.12-6, so the upgrade may need to overwrite any untracked pyc files created. If you get errors like these

libxml2: /usr/lib/python3.10/site-packages/__pycache__/drv_libxml2.cpython-310.opt-1.pyc exists in filesystem
libxml2: /usr/lib/python3.10/site-packages/__pycache__/drv_libxml2.cpython-310.pyc exists in filesystem
libxml2: /usr/lib/python3.10/site-packages/__pycache__/libxml2.cpython-310.opt-1.pyc exists in filesystem
libxml2: /usr/lib/python3.10/site-packages/__pycache__/libxml2.cpython-310.pyc exists in filesystem

when updating, use

pacman -Syu --overwrite /usr/lib/python3.10/site-packages/__pycache__/\*

to perform the upgrade.

Starting with libxcrypt 4.4.21, weak password hashes (such as MD5 and SHA1) are no longer accepted for new passwords. Users that still have their passwords stored with a weak hash will be asked to update their password on their next login.

If the login just fails (for example from display manager) switch to a virtual terminal (Ctrl-Alt-F2) and log in there once.

As some of you may have read over the past days, there has been an ownership dispute over the freenode.net network. The IRC network has been used by Arch Linux and many other projects over the past decades as a platform for discussion and support. The dispute led to the exodus of most former freenode staff from the network and the founding of a new network: libera.chat

Starting today, Arch Linux and its sister projects Arch Linux ARM and Arch Linux 32 will begin migrating the official IRC channels from freenode.net to libera.chat. Please bear with us as this can …

The installation medium now provides a guided installer.

This addition to the default method of installation (based on the installation guide) is similar to the other methods.

If you use this installer, do not forget to mention it when asking for support and also to provide the archinstall log, when asked.

As linux-lts moved to the 5.10 version, all official kernels of Arch Linux now support zstd compressed initramfs images, so mkinitcpio is switching to zstd compressed images by default with version 30, which is currently on [testing].

If, for any reason, you are using a kernel version prior to 5.9, make sure to change mkinitcpio.conf COMPRESSION to use one of the compressors supported, like gzip, otherwise you will not be able to boot images generated by mkinitcpio.
