+## v0.78.0 — 2026-05-29
+
+pi `0.77.0` → `0.78.0` bump (first container build on the pi 0.78 line, published upstream 2026-05-29). Built against `joakimp/opencode-devbox:base-latest` (unchanged from the v0.77.0 build).
+
+### Bumped: pi 0.77.0 → 0.78.0
+
+**New Features**
+- **Named startup sessions** — `--name` / `-n` sets the session display name before startup across interactive, print, JSON, and RPC modes.
+- **Clickable file tool paths** — built-in file tool titles render OSC 8 `file://` hyperlinks when the terminal supports them, including supported tmux clients.
+
+**Added**
+- Exported `convertToPng` for extension authors.
+- Exported `parseArgs` and type `Args` for extension authors.
+- Added a resume command hint when exiting interactive sessions.
+- Added custom Amazon Bedrock request header support.
+
+**Fixed**
+- Fixed early interactive input typed before the prompt loop starts so it is buffered instead of dropped.
+- Fixed OpenRouter Moonshot Kimi K2.6 requests to use `system` instead of unsupported `developer` messages.
+- Fixed OSC 8 hyperlinks to pass through tmux when the client supports them.
+- Fixed ANSI text wrapping to avoid stack overflows on very long wrapped lines.
+- Fixed OpenAI Codex Responses SSE streams to abort response body reads after terminal events.
