What is Apptainer?

Apptainer's CDI support needed a privilege-escalation fix four months after it shipped.

Apptainer 1.5.0 in May added Container Device Interface support, a BuildKit bootstrap for building SIF images from Dockerfiles, and IPFS pulls. The point releases since have handled the cost. 1.5.4 fixed a high-severity local privilege escalation in suid mode by stopping non-root users from passing --cdi-dirs, added a config default for CDI directories, and restored rootless builds on Ubuntu 24.04 and later. 1.5.5 raises the minimum Go version to block compromised emSign intermediate certificates and fixes pull destinations and suid fakeroot mounts.

What is Lima?

Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI

Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.

Apptainer's CDI support needed a privilege-escalation fix four months after it shipped.

◆ Current state

Apptainer 1.5.0 in May added Container Device Interface support, a BuildKit bootstrap for building SIF images from Dockerfiles, and IPFS pulls. The point releases since have handled the cost. 1.5.4 fixed a high-severity local privilege escalation in suid mode by stopping non-root users from passing --cdi-dirs, added a config default for CDI directories, and restored rootless builds on Ubuntu 24.04 and later. 1.5.5 raises the minimum Go version to block compromised emSign intermediate certificates and fixes pull destinations and suid fakeroot mounts.

◆ Where it's heading

The 1.5 line is spending its point releases on the edges of the features it added: CDI's flexibility turned into an escalation path under suid, and unprivileged builds keep breaking as distributions tighten AppArmor and drop tools. The fix for CDI was to move control to the admin's config file, a pattern suid deployments will likely see more of.

◆ Prediction

Expect more 1.5.x releases on unprivileged build compatibility and suid restrictions; further CDI coverage remains the most likely feature addition.

Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI

◆ Current state

Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.

◆ Where it's heading

The any-guest, any-host direction now reaches all three desktop platforms in one release, and each host gets a feature suited to its own virtualization stack. The menu interface is a different kind of addition: it aims at people who do not want to memorize the CLI. LFX mentees and outside contributors continue to carry much of this work, and the project's experimental-first labeling still applies to the biggest items.

◆ Prediction

A 2.3.0 final is the next step after rc.0. The HCS driver and Linux network modes should stay experimental there, following the pattern earlier platform additions took.
