Apptainer
Apptainer's CDI support needed a privilege-escalation fix four months after it shipped.
A side-by-side editorial comparison of Cobbler and Talos Linux — release velocity, themes, recent moves, and the top alternatives to consider.
Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.
Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.
Talos 1.15's alpha keeps moving: a silent containerd config trap and declarative CPU control
Talos is on v1.15.0-alpha.2 while stable branches keep receiving maintenance releases such as v1.13.12. The alpha adds boot partition waiting for late-enumerated disks, container swap limits and a declarative CPUScalingConfig document. It also generates containerd configuration version 4, under which settings that moved between versions are silently ignored in custom CRI configs apart from a logged warning.

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.
Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

It also generates containerd configuration version 4, under which settings that moved between versions are silently ignored in custom CRI configs apart from a logged warning.
The 1.15 cycle extends Talos's habit of replacing kernel arguments and raw system settings with typed configuration documents. Networking dominated 1.14 and the first 1.15 alpha; alpha.2 widens that approach to hardware and resource control, and consolidates talosctl around a shared --namespace flag. The containerd change is the real operational cost of the cycle, because a customized metrics or gRPC section stops taking effect with only a logged warning.
Expect more typed documents for settings that still live in kernel arguments or SysfsConfig keys, and further alphas before a beta. Operators with CRICustomizationConfig patches should expect migration guidance to feature in the eventual 1.15 upgrade notes.
