We are making
dbus-broker our default implementation of D-Bus, for
improved performance, reliability and integration with systemd.
For the foreseeable future we will still support the use of
the previous implementation. Pacman will ask you whether to install
dbus-daemon-units. We recommend picking the

We are happy to announce that the migration of the bugtracker to GitLab is done! 🥳
Thanks to everyone who has helped during the migration!
This means the issue tracker and merge requests on the GitLab package repos are now enabled.
The old bugtracker will subsequently be closed down. For archiving reasons there will be a static copy so that links (for example the randomly picked Task #56716) are still stable, migrated bugs have a closing comment pointing to the new URL on GitLab.
Packaging bugs are now opened on the repo hosting the corresponding packaging sources, the "Add a new Bug" button on the package page on archlinux.org will automatically direct you to the correct place to open the issue. The workflow afterwards is mostly the same, first our Bug Wranglers will have a look at the issues and triage them, and then they will be handed over to the respective Package Maintainers to fix. A list of all issues can be found here.
If you do not have an account for GitLab already (which authenticates against our SSO service), please write us a mail with your desired username to firstname.lastname@example.org as advised in the banner.
We are introducing a change in JDK/JRE packages of our distro. This is
triggered from the way a JRE is build in modern versions of Java (>9). We are
introducing this change in Java 21.
To sum it up instead of having JDK and JRE packages coexist in the same system
we will be making them conflict. The JDK variant package includes the runtime
environment to execute Java applications so if one needs compilation and
runtime of Java they need only the JDK package in the future. If, on the other
hand, they need just runtime of Java then JRE (or jre-headless) will work.
This will (potentially) require a manual user action during upgrade:
- If you have both JDK and JRE installed you can manually install the JDK
pacman -Sy jdk-openjdk && pacman -Su and this removes the JRE related packages.
- If you have both JRE and JRE-headless you will need to choose one of
them and install it manually since they would conflict each other now.
- If you only have one of the JDK/JRE/JRE-headless pacman should resolve
dependencies normally and no action is needed.
At the moment this is only valid for the upcoming JDK 21 release.
With shadow >=
4.14.0, Arch Linux's default password hashing algorithm changed from SHA512 to yescrypt.
umask settings are now configured in
/etc/login.defs instead of
This should not require any manual intervention.
Reasons for Yescrypt
The password-based key derivation function (KDF) and password hashing scheme yescrypt has been chosen due to its adoption (readily available in libxcrypt, which is used by pam) and its stronger resilience towards password cracking attempts over SHA512.
Although the winner of the Password Hashing Competition has been argon2, this algorithm is not yet available in libxcrypt (attempt one, attempt two).
YESCRYPT_COST_FACTOR setting in
/etc/login.defs is currently without effect, until pam implements reading its value. If a
YESCRYPT_COST_FACTOR higher (or lower) than the default (
5) is needed, it can be set using the
rounds option of the
pam_unix module (i.e. in
General list of changes
- yescrypt is used as default password hashing algorithm, instead of SHA512
- pam honors the chosen
/etc/login.defs and does not override the chosen method anymore
- changes in the filesystem (>=
2023.09.18) and pambase (>=
20230918) packages ensure, that
umask is set centrally in
/etc/login.defs instead of
