What is Kata Containers?

With the Rust runtime shipped, Kata turns to GPUs and slimmer packaging.

Kata Containers ships monthly, and 4.1.0 is the first release after the Rust runtime became the default. It is consolidation work: the static release tarball is split by runtime, the GPU extension is built without depending on the monolithic image, NVIDIA libraries are chiselled down from a filelist, and kata-deploy stops shipping virtiofsd when shared_fs is disabled. Dragonball merged its three network device managers into one, EROFS backing mode became configurable, and the CI matrix churned across s390x, arm64 and ppc64le.

What is NetBird?

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

With the Rust runtime shipped, Kata turns to GPUs and slimmer packaging.

◆ Current state

Kata Containers ships monthly, and 4.1.0 is the first release after the Rust runtime became the default. It is consolidation work: the static release tarball is split by runtime, the GPU extension is built without depending on the monolithic image, NVIDIA libraries are chiselled down from a filelist, and kata-deploy stops shipping virtiofsd when shared_fs is disabled. Dragonball merged its three network device managers into one, EROFS backing mode became configurable, and the CI matrix churned across s390x, arm64 and ppc64le.

◆ Where it's heading

The rewrite arc has closed and an accelerator arc is opening in its place. Four separate changes in this release touch NVIDIA support — library chiselling, Fabric Manager topology, local CUDA repository support, and decoupling the GPU extension from the monolithic image — which is the shape of a project preparing for confidential GPU workloads rather than incidental hardware support. The packaging work points the same way: splitting tarballs by runtime and dropping unused components matters when the image is being pulled onto every node of a GPU cluster.

◆ Prediction

Expect the next releases to continue narrowing the shipped artifact and to deepen NVIDIA support toward attested GPU workloads, rather than to revisit the runtime itself.

5.0

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

◆ Current state

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

◆ Where it's heading

After v0.81 focused on device trust through certificate posture checks, v0.82 is about the management plane's storage and on hardening the built-in SSH server. Deprecating Rosenpass signals a change in how NetBird approaches post-quantum key exchange, though the entries do not name the replacement.

◆ Prediction

Expect v0.82.0 final with the MySQL removal intact, and a later release introducing the Rosenpass replacement.
