# Changelog ## 0.1.5 — 2026-10-28 ### Changed - Use `@opencode/codemode` 2.2.0. The published interpreter sources are unchanged from 2.1.4; Acorn stays 8.15.0 and Effect stays 4.0.1. This dependency update alone does not change the tool bridge, limits, preflight, or result contract; `for...in` remains rejected. ### Improvements - Admit direct `String.raw` tagged templates through preflight for backslash-heavy shell commands and heredocs. Other tags stay rejected; substitutions retain the existing compatibility checks, and source is never rewritten. Document interpolation/backtick caveats in model guidance and the shell examples. - Include bounded upstream recovery suggestions in model-visible error/warning text, before logs and return data, without automatic retry or replay. - Show an error-attempt count such as `1 failed` only when failures exist, including failures hidden by the last-eight-call preview. Do not add total or success counts, count cancellations as failures, or change script success. - Nudge models to use JS template literals for multiline shell commands and heredocs, with explicit guidance on embedded backticks, interpolation, and backslash escaping. Source validation and execution behavior are unchanged. ## 0.1.4 — 2026-10-26 ### Changed - Admit `switch`/`case` and `new Date`, `new RegExp`, `new Map`, `new Set`, `new URL`, `new EvalError`, and `new URIError` through preflight. CodeMode 2.1.4 already runs them. Other constructors and unsupported syntax stay rejected before execution. - Keep `for...in` rejected before any host effects: CodeMode 2.1.4 skips inherited properties and still visits keys deleted during iteration. - Name `codemode_o` and native `codemode` explicitly as the model-only direct-call targets; `bash` and `edit` remain ordinary host calls inside a program. - Keep short programs that call native `bash` and `edit` on `codemode_o`. Those host calls already ran through Pi's tool bridge; the tool guidance no longer treats a shell command or file edit as a reason to switch to native `codemode`. - Use `@opencode/codemode` 2.1.4. Upstream promise scheduling now holds the main job until leftover promise work is interrupted; the extension's tool bridge, limits, and result contract are unchanged. Acorn stays 8.15.0 and Effect stays 4.0.1. ## 0.1.3 — 2026-10-25 ### Improvements - Simplify the source-preview notice to `Preview; expand for original`. ### Fixes - Allow OpenCode-supported regular-expression literals through preflight instead of incorrectly reporting `NativeCodemodeRequired`; preserve syntax errors for invalid patterns/flags and existing BigInt/Pi-only restrictions. - Preserve Pi's native pending/success/error panel backgrounds when call rows are shortened or wrapped, including duration text and trailing padding. ## 0.1.2 — 2026-10-25 ### Improvements - Show live, per-attempt host-call rows with bounded argument/error previews, status and duration. Preserve duplicate names, settle cancellation after host cleanup, and retain detached records for restored sessions. - Format source previews at AST boundaries without changing execution input; preserve literals/comments/templates and fall back to raw source on parse or structure-check failure. Expansion also exposes the original execution source. ### Fixes - Distinguish invalid script syntax (`SourceSyntaxError`) and unexpected preflight parser exceptions (`PreflightParserError`) from native-required compatibility limitations; do not recommend native replay for these failures. - Preserve bounded Acorn messages and valid UTF-16 offsets/line-column locations, including the string start and newline detection position. Explain JS/JSON newline escaping without rewriting source or executing any host tool. - Add raw LF/CR/CRLF, escaped heredoc/Korean multi-call, parser failure injection, diagnostic budget, and isolated real-session regression coverage. ## 0.1.1 — 2026-10-24 ### Improvements - Prefer `codemode_o` for short, compatible programs through concise model context guidance; choose native `codemode` upfront for Pi-specific features, images, MCP readiness, long-running work, or uncertain compatibility. - Separate LLM tool selection from compatibility-only preflight validation. Preserve the historical routing helper and metadata for compatibility. - Report compatibility outcomes in `details.preflight`; keep native-availability caveats explicit and never automatically delegate or replay execution failures. - Add regression coverage for active/inactive/unloaded prompt guidance and duplicate-free reactivation; update tool-selection and testing documentation. ### Known limits - Guidance influences model choice; it is not enforced routing or a performance guarantee. Custom prompts and higher-priority instructions may affect it. - MCP startup/reconnect readiness coordination remains out of scope; prefer native `codemode` for MCP workflows. ## 0.1.0 — 2026-10-23 Initial public release. ### Features - Add `codemode_o`, backed by OpenCode CodeMode 2.1.0, alongside Pi's native `codemode`; neither tool replaces or recursively invokes the other. - Discover already-callable Pi tools with OpenCode's synchronous `search` API. - Preserve Pi tool validation, permission/result hooks, and nested-call audits. - Reject native-only programs before execution, without automatic fallback or replay after side effects. - Bound final text output to 65,536 UTF-8 bytes with visible diagnostics and truncation indicators; await cooperative host cancellation and cleanup. - Show highlighted source, collapsible output, and execution duration in the TUI. ### Compatibility and verification - Require Node.js >= 22.19.0 and Pi >= 0.99.0, < 2.0.0. - Add CI for Node 22.19.0 / 24.x and Pi 0.99.0 / 1.3.0 / 1.4.0, including isolated scripted real-SDK sessions. See [TESTING.md](TESTING.md). - Include a sourced historical `pi-codemode-bench` comparison in the README, with measured versions, timing boundaries, and contrary CPU-heavy results. ### Known limits - The interpreter is not an OS or memory-isolation sandbox, and supports only a JavaScript subset. Use trusted host tools. - The 30-second deadline requests interruption; a host tool that never settles can delay delivery indefinitely. Cancellation does not roll back side effects. - Historical benchmark results are not a current-release performance guarantee; no live-provider E2E guarantee is included.
