 ## Unreleased
 
+## 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 update` reconciles 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.
+
+- **Bump:** pi `@earendil-works/pi-coding-agent@0.75.5` baked at `/usr/bin/pi` (via `PI_VERSION=latest` resolving to 0.75.5 at build time — no Dockerfile change needed).
+- No image-side changes from v0.75.4 beyond the pi npm version. Built on `joakimp/opencode-devbox:base-latest` which itself is unchanged (cache-hit on `base-35ee5fe7861a` since v1.14.50b).
+
 ## v0.75.4 — 2026-05-21
 
 pi `0.75.3` → `0.75.4` bump (one upstream patch release). Plus the AGENTS.md documentation-drift sweep clause that landed on `main` between v0.75.3 and now.
