The 2026-10-24 commit 1538860e0cc71942f79166d73b8944e14ff55626 in strands-agents/box added an ARM64 Linux preview packaging path. This repository is a Rust sandbox that restricts what AI agents can execute, read, and write, as well as network access. No specific release version is given in the commit information, and the workflow was changed to specify a preview channel by appending `-linux-preview.N` to the version.
The new path uploads a tarball for ARM64 Linux to prereleases, and the build baseline is Amazon Linux 2023. The Linux x86_64 tarball is kept as a run artifact, and musl builds and deb/rpm packages are not produced. A packaging test job that checks the release source and archive selection was added to CI. According to the repository description, Box restricts the scope of execution by keeping secrets outside the agent through OS isolation, a default-deny policy, and credential injection.
This is the addition of a preview packaging path, not official Linux support. The repository description keeps Linux support in the planning stage, and `EXPERIMENTAL_LINUX_SUPPORT` has also been set in the containment workflow. Whether an actual preview release has been published cannot be confirmed from this commit alone.
