Agentic Sandbox v2026.6.26

Released: 2026-06-20 Tag: `v2026.6.26` Previous: `v2026.6.25` Compare: `v2026.6.25...v2026.6.26`

What This Release Is

v2026.6.26 is a release-pipeline synchronization release. It keeps the v2026.6.25 runtime and API fixes, then moves Linux ARM64 release artifacts off the mutsu SSH matrix so publication is no longer blocked by stale post-upload state in the mutsu Linux leg.

Highlights

  • `aarch64-unknown-linux-gnu` `agent-client` and `sandboxctl` artifacts now

build on the Linux runner with the GNU aarch64 cross toolchain.

  • mutsu remains responsible only for the Apple Silicon Darwin artifact.
  • The Linux release artifact job label now reflects the full Linux matrix

instead of saying x86_64-only.

  • The release remains explicit that non-x86_64 Linux tarballs ship the in-VM

binaries only; `agentic-mgmt` still requires the native x86_64 GNU archive because it links to the system libvirt C library.

Verification

python3 - <<'PY'
import yaml
with open('.gitea/workflows/ci.yaml', 'r', encoding='utf-8') as f:
    yaml.safe_load(f)
print('ci yaml parsed')
PY
git diff --check
file agent-rs/target/aarch64-unknown-linux-gnu/release/agent-client \
     cli/target/aarch64-unknown-linux-gnu/release/sandboxctl

Gitea Actions runs `1502`, `1503`, and `1504` completed successfully on `9760108` after the workflow fix landed.

Operator Notes

  • Use `v2026.6.26` when you need the v2026.6.25 bootstrap/admin-v2 fixes plus

a release workflow that keeps Linux ARM64 artifacts in the Linux runner lane.

  • `v2026.6.25` remains useful for source review, but its release workflow hit a

stale post-upload mutsu Linux job state during publication.
