Symmetric with the gitleaks/git-crypt inherit-note already present. Cross-references opencode-devbox commit 668592d (Unreleased), which bakes /etc/ssh/ssh_config.d/00-devbox-controlmaster.conf with a writable /tmp/sshcm ControlPath. pi-devbox picks this up automatically on its next build against base-latest; no Dockerfile change here. Documents the symptom users see today inside pi-devbox <= v0.75.5b (unix_listener Read-only file system on \~/.ssh/cm) and the fact that pi --ssh user@host inside the container is currently silently broken until the cascade lands.

Changelog
All notable changes to the pi-devbox container image.
Tags follow the pi npm version: v{pi_version}[letter] — bare tag for the first build on a new pi release, letter suffix (b, c, …) for container-level rebuilds on the same version.
Unreleased
Inherited from opencode-devbox base: SSH ControlMaster on a writable socket path
No Dockerfile change here — just a note that the next pi-devbox release built against a fresh joakimp/opencode-devbox:base-latest will pick up the system-wide SSH ControlMaster default (/etc/ssh/ssh_config.d/00-devbox-controlmaster.conf → ControlPath /tmp/sshcm/%r@%h:%p, ControlMaster auto, ControlPersist 10m). This unblocks ssh and pi --ssh user@host from inside the container when ~/.ssh is bind-mounted read-only from the host (the standard pi-devbox compose layout) — previously, OpenSSH's default ControlPath under ~/.ssh/cm/ was unwritable, so multiplexing failed with unix_listener: cannot bind ... Read-only file system and ssh fell back to fresh TCP connections, which on residential CGNAT manifested as banner-exchange timeouts. The fix is purely additive (per-container /tmp/sshcm dir, mode 700, created by entrypoint) and user ~/.ssh/config per-host overrides still win because Debian's stock ssh_config sources ssh_config.d/*.conf before its own Host * block. See opencode-devbox CHANGELOG Unreleased for the base-side details.
Inherited from opencode-devbox base: gitleaks + git-crypt
No Dockerfile change here — just a note that the next pi-devbox release built against a fresh joakimp/opencode-devbox:base-latest will include gitleaks (newly added to the base) and git-crypt (was always installed via apt; just wasn't called out). Both are useful inside the container for repos that use a gitleaks pre-commit hook or git-crypt-encrypted canonical config and don't want host-side dependencies. See opencode-devbox CHANGELOG Unreleased for the base-side details.
v0.75.5b — 2026-05-23
Recovery release fixing a silent cache-hit regression discovered in the v0.75.5 image. All four releases v0.74.0 through v0.75.5 had been shipping the same image bytes because the Dockerfile's npm install -g @earendil-works/pi-coding-agent (bare, when PI_VERSION=latest) produces an identical layer-hash across builds. Combined with the registry buildcache, Docker reused the layer from whatever pi version was current when the cache was first populated.
Verification: docker manifest inspect joakimp/pi-devbox:vX.Y.Z showed identical SHA256 digests on both linux/amd64 and linux/arm64 for v0.74.0, v0.75.3, v0.75.4, v0.75.5. Users on :latest were getting whatever pi version was baked into the v0.74.0 build (probably 0.74.0 itself).
- Workflow fix: Both
smokeandpublishjobs now derivePI_VERSIONfromgithub.ref_name(e.g.v0.75.5b→0.75.5) and pass it as a build-arg. The Dockerfile's existingif PI_VERSION=latestbranch never fires in CI now — always takes the@${PI_VERSION}branch — so the layer-hash includes the version and cache invalidates correctly. - Smoke test: New
run_expecthelper assertspi --versionoutput containsEXPECTED_PI_VERSION(passed from the resolve step). Would have caught this regression on v0.75.3 if it had existed. - Dockerfile: Comment added above
ARG PI_VERSION=latestdocumenting the cache-hit footgun and pointing at the workflow's resolve step + AGENTS.md gotcha. - AGENTS.md: New convention bullet explaining the cache-hit class of bug and noting the latent same-bug in opencode-devbox's
with-pivariants (currently masked by OPENCODE_VERSION bumps).
No image-side changes vs v0.75.5 intent — this build will produce the actual pi 0.75.5 image content that v0.75.5 was supposed to ship.
v0.75.5 — 2026-05-23
pi 0.75.4 → 0.75.5 bump (one upstream patch release, two days after v0.75.4).
Notable upstream changes (from pi's CHANGELOG):
- Cleaner read tool output (collapsed cards show only the read line; Ctrl+O expands).
- Faster file tools on Windows (async fs ops during streaming, image resize off the main TUI thread).
- More reliable package updates (
pi updatereconciles git-pinned refs without losing settings). - Custom Anthropic-compatible adaptive thinking via
compat.forceAdaptiveThinking. - Several bash/read tool card display fixes; macOS Bun clipboard sidecar resolution; per-session OpenCode-Zen routing headers; Amazon Bedrock token cap fix.
Plus a new pi 0.74.2 rescue release advising Node 20 users to upgrade Node before going to newer Pi versions — the devbox base image runs newer Node so this doesn't affect us, but worth noting for users running pi outside the devbox.
