# v0.8.9

**Released:** 2026-08-22

Dependency maintenance (GitHub Actions).

## Changes

- Bump `actions/setup-node` 6.5.0 → 7.0.0 (PR #150) — upstream ESM migration; our workflows pass no action inputs, no behavioral change.
- Bump `docker/setup-buildx-action` 4.2.0 → 4.3.0 (PR #149).

Both remain pinned to full commit SHAs per the v0.8.6 supply-chain policy; tags verified against upstream before merge. Master CI green on the exact merge commits.
