ALL FOUR releases v0.74.0 -> v0.75.5 had been shipping the same image bytes due to a Docker layer-cache hit on the bare 'npm install -g @earendil-works/pi-coding-agent' command (when PI_VERSION=latest). The command string is identical across builds, so the layer-hash is identical, so registry buildcache (cache-from/cache-to) silently reuses 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. DISCOVERED 2026-05-23 by user trying to update pi-devbox on MBP-M1 and seeing pi 0.74.0 reported despite pulling v0.75.5. CHANGES .gitea/workflows/docker-publish.yml — both smoke and publish jobs get a new 'Resolve PI_VERSION from tag' step that strips the leading 'v' and any trailing letter suffix from github.ref_name. Result is passed as a build-arg to docker/build-push-action so the npm install layer's hash includes the concrete version, forcing cache miss when pi bumps. scripts/smoke-test.sh — new run_expect helper that asserts pi --version contains the EXPECTED_PI_VERSION env var. Smoke job sets this from the resolve step output. Would have caught this regression on v0.75.3. Dockerfile — comment block above ARG PI_VERSION=latest documenting the cache-hit footgun. The 'if latest' branch in the install RUN is preserved for local dev convenience but never fires in CI now. AGENTS.md — new convention bullet explaining the cache-hit class of bug and noting the latent same-bug in opencode-devbox's with-pi variants (currently masked by OPENCODE_VERSION bumps; will manifest when cutting a vN.N.Nb-style opencode-version-unchanged release that only bumps pi). CHANGELOG.md — full entry under v0.75.5b describing the recovery, the silent-failure mechanism, and the verification steps. NO IMAGE-CONTENT CHANGES vs v0.75.5 INTENT. This build produces the actual pi 0.75.5 image content that v0.75.5 was supposed to ship. NEXT FOLLOWUP (parked, not in this commit) opencode-devbox should get the same workflow change for its build-variant-with-pi and build-variant-omos-with-pi jobs. Currently masked because every release also bumps OPENCODE_VERSION which invalidates the cache, but that masking would fail on a pi-only bump release.

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
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.
