Release notes

Pi 0.79.8

New version of pi. Download from npm or view release on GitHub.

New Features

  • Selective provider base entry points - SDK users can pair @earendil-works/pi-ai/base and @earendil-works/pi-agent-core/base with explicit provider registration to keep bundled applications from including unused provider transports. See pi-ai Base Entry Point and pi-agent-core Base Entry Point.
  • Mistral prompt caching - Mistral sessions now use provider-side prompt caching with session affinity and cached-token usage/cost accounting. See API Keys and Environment Variables.
  • Post-compaction token estimates - Compact results and compaction events now include estimated post-compaction token counts so clients can show the approximate context reduction. See RPC compact and compaction events.
  • OpenRouter Fusion alias - openrouter/fusion is available as a built-in OpenRouter model alias. See API Keys.

Added

  • Added inherited @earendil-works/pi-ai/base and @earendil-works/pi-agent-core/base entry points for selective provider registration in bundled applications (#5348 by @FredKSchott).
  • Added inherited Mistral prompt caching using the pi session ID as prompt_cache_key, including cached-token usage and cost accounting (#5854).
  • Added estimated post-compaction token counts to compact results and compaction events (#5877).
  • Added the inherited OpenRouter Fusion alias as openrouter/fusion (#5866 by @dannote).

Pi 0.79.7

New version of pi. Download from npm or view release on GitHub.

New Features

  • Automatic theme mode - /settings can choose separate light and dark themes and follow terminal color-scheme changes. See Selecting a Theme.
  • Self-only updates by default - pi update now updates pi only, with pi update --all for updating pi and packages together. See Install and Manage.
  • Extension API helpers - extensions can use CONFIG_DIR_NAME for project config paths and import edit diff helpers for edit-style diffs. See ctx.cwd and SDK Exports.
  • Warp inline images - Warp terminals now get inline image rendering through Kitty graphics detection. See Image.

Added

  • Added automatic theme mode so /settings can use separate light and dark themes and follow terminal color-scheme changes (#5874).
  • Added inherited Warp terminal image capability detection so inline images render through Warp's Kitty graphics support (#5841 by @dodiego).

  • Exported edit diff helpers (generateDiffString, generateUnifiedPatch, and EditDiffResult) from the public API for extensions that need edit-style diffs (#5756 by @xl0).

Changed

  • Changed bare pi update to update only pi, added pi update --all for updating pi and extensions together, and clarified extension update prompts.
  • Reserved / in theme names for automatic light/dark theme settings.
  • Updated extension docs, examples, runtime help, trust prompts, and config labels to use the configured project config directory instead of hardcoded .pi paths.

  • Added an xp footer marker when experimental features are enabled.
  • Added a global httpProxy setting that applies as HTTP_PROXY and HTTPS_PROXY for Pi-managed HTTP clients (#5790).

New version of pi. Download from npm or view release on GitHub.

Fixed

  • Fixed inherited OpenAI GPT-5.4/GPT-5.5 and OpenAI Codex GPT-5.4/GPT-5.4 mini/GPT-5.5 context window metadata to use the observed 272k-token Codex backend limit, avoiding a billing hazard from prompts above Codex's accepted limit (reported by @trethore).

New version of pi. Download from npm or view release on GitHub.

New Features

  • Clearer Bedrock validation guidance - Amazon Bedrock data retention validation errors now link to AWS data retention documentation. See Amazon Bedrock.

Added

  • Added an experimental first-time setup flow behind PI_EXPERIMENTAL=1 that asks for a dark/light theme choice (preselecting the detected appearance) and opt-in analytics data sharing on first launch with the default agent directory; opting in stores a trackingId in settings.json (#5587 by @vegarsti).

Pi 0.79.1

New version of pi. Download from npm or view release on GitHub.

New Features

  • Claude Fable 5 - Claude Fable 5 is now available on the Anthropic and Amazon Bedrock providers, with adaptive thinking and xhigh effort support.
  • Prompt template defaults - Prompt templates can use default positional arguments such as ${1:-7} for optional values. See Prompt Template Arguments.

Release notes

Pi 0.76.0

New version of pi. Download from npm or view release on GitHub.

New Features

  • Explicit session IDs for automation - --session-id <id> lets scripts create or resume an exact project-local session. See Sessions.

  • Better terminal editing across environments - Apple Terminal Shift+Enter, Windows/JetBrains capability detection, and Unicode-aware word navigation improve interactive editing. See Terminal setup and Keybindings.

Added

  • Added --session-id to let CLI callers use an exact project-local session ID, creating it if missing (#4874).
  • Added excludeFromContext flag to the bash RPC command for parity with the internal executeBash API (#5039).

Pi 0.75.5

New version of pi. Download from npm or view release on GitHub.

New Features

  • Cleaner read tool output - Collapsed read tool cards now show only the read line by default, while Ctrl+O still expands the full file content.
  • Faster file tools on Windows - Built-in file tools now use async filesystem operations during streaming, and image resizes run off the main TUI thread in a worker.
  • More reliable package updates - pi update and git package installs now reconcile pinned git refs and keep package settings intact. See Packages.
  • Custom Anthropic-compatible adaptive thinking - Custom provider model configs can opt into adaptive-thinking Claude behavior with compat.forceAdaptiveThinking. See Custom providers and Models.

Added

  • Added compat.forceAdaptiveThinking support to custom Anthropic-compatible model configuration docs and validation (#4797 by @mbazso).
  • Added a standard unified patch to edit tool result details for SDK consumers (#4821).
  • Added a Codex subscription login method selector with device-code auth for headless environments.

Changed

  • Changed collapsed read tool cards to show only the read line until expanded (#4916).
  • Replaced the inherited optional koffi dependency for Windows VT input with a tiny vendored native helper, reducing install size while preserving Shift+Tab handling (#4480).
  • Changed the root development install documentation to use npm install --ignore-scripts (#4868).

Release notes

Pi 0.75.4

New version of pi. Download from npm or view release on GitHub.

New Features

  • Hardened npm install and release path - Pi now ships the CLI with a generated shrinkwrap for transitive dependencies, blocks accidental lockfile changes, verifies dependency pinning and lifecycle-script allowlists in checks, disables lifecycle scripts for self-update and local release installs where supported, and smoke-tests isolated npm and Bun installs before release. See Supply-chain hardening.

Added

  • Added interactive update notes after pi update runs, so users can see the installed version's changelog before continuing (#4724 by @mitsuhiko).
  • Exported image resize utilities from the package root for SDK consumers (#4775 by @xl0).

Changed

  • Changed source syntax to avoid TypeScript constructs that require JavaScript emit, keeping core sources compatible with Node.js strip-only TypeScript checks.
  • Removed web UI workspace references from the CLI package and dropped the package-level development watch script.
  • Published npm installs now include an npm-shrinkwrap.json to lock transitive dependencies for the CLI package.
  • Improved terminal theme detection for light/dark and truecolor handling.
  • Changed self-update package-manager commands to disable lifecycle scripts during reinstall.

  • Fixed Xiaomi MiMo generated model metadata to replay assistant tool-call messages with reasoning_content for thinking-mode multi-turn requests, inherited from @earendil-works/pi-ai (#4678).
  • Fixed Windows external editor handoff so vim/nvim can receive input after opening from the TUI (#4612).
  • Fixed Windows npm self-updates to move loaded native dependency packages out of the active install before reinstalling pi (#4157).
  • Fixed pi update --self detection for pnpm v11 global installs whose package path resolves through the pnpm store (#4647).
  • Fixed Windows pnpm self-updates to resolve pnpm command shims and run through pnpm instead of requiring manual updates (#4157).
  • Fixed Windows npm-family command execution to use cross-spawn instead of parsing .cmd shim internals (#4665).
