pi 0.75.5 → 0.76.0 (published upstream 2026-05-27 20:03 UTC). First
pi-devbox release built against opencode-devbox base-latest carrying the
SSH ControlMaster bake-in (commit 668592d) and gitleaks (73a7f96) — both
inherited transparently with no Dockerfile change here. PI_VERSION is
resolved from the git tag by the workflow (v0.75.5b cache-hit fix), so
no Dockerfile default bump needed.
Workflow change: registry cache-export removed from publish step. buildkit
mode=max cache-export to registry-1.docker.io reproducibly returns HTTP 400
(Hub-CDN protocol mismatch with buildx 0.34.x, surfaced ~2026-05-23).
Diagnosed during opencode-devbox v1.15.12 manual publish: image push works,
only --cache-to fails. Pi-devbox would hit the same regression on the next
tag push without this fix. See opencode-devbox CHANGELOG v1.15.12 for the
full root-cause analysis. Pi-devbox is single-stage with a tiny diff (npm
install pi only) on top of base-latest, so builds are fast even uncached.
