- 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`.
## [0.79.10] - 2026-06-22
### New Features
- **Extension compaction event context** - Extension `session_before_compact` and `session_compact` events now include `reason` and `willRetry`, so extensions can distinguish manual `/compact`, threshold auto-compaction, and overflow retry flows. See [session_before_compact / session_compact](docs/extensions.md#session_before_compact--session_compact) and [Custom Summarization via Extensions](docs/compaction.md#custom-summarization-via-extensions).
- **Safer update flow** - `pi update` installs the exact checked Pi version, and update notices show the changelog URL, making upgrades more predictable. See [Install and Manage](docs/packages.md#install-and-manage).
### Added
- Added `reason` and `willRetry` metadata to extension `session_before_compact` and `session_compact` events so extensions can distinguish manual, threshold, and overflow compaction flows ([#5962](https://github.com/earendil-works/pi/pull/5962) by [@PizzaMarinara](https://github.com/PizzaMarinara)).
### Fixed
- Fixed the `find` tool to respect nested git repository boundaries when parent `.gitignore` rules ignore the nested repo ([#5960](https://github.com/earendil-works/pi/issues/5960)).
- Fixed the usage docs slash command table to include `/trust` and `/import` ([#5959](https://github.com/earendil-works/pi/issues/5959)).
- Fixed inherited OpenAI-compatible streaming to preserve encrypted `reasoning_details` that arrive before matching tool call deltas ([#5114](https://github.com/earendil-works/pi/issues/5114)).
- Fixed broken TUI documentation links to the plan-mode extension example ([#5957](https://github.com/earendil-works/pi/issues/5957)).
- Fixed transient extension UI and session-start messages emitted during session replacement or reload so they remain visible, and kept reload input blocked until reload completes ([#5943](https://github.com/earendil-works/pi/issues/5943)).
- Fixed the plan-mode example to preserve active custom tools, skip the action prompt when no plan is found, and queue refinement/execution follow-ups correctly from `agent_end` ([#5940](https://github.com/earendil-works/pi/issues/5940)).
- Fixed `pi update` to install the exact version returned by the Pi update check, make `--force` reinstall that checked version, fail instead of falling back to an unversioned reinstall when no version is available, and report both the old and updated versions.
- Fixed update notifications to display the actual changelog URL as the hyperlink text.
## [0.79.9] - 2026-06-20
### New Features
- **Chat-template thinking compatibility** - OpenAI-compatible custom providers can map Pi thinking levels into `chat_template_kwargs`, enabling vLLM/Hugging Face chat-template models such as DeepSeek to use provider-native thinking controls. See [Custom Provider API Types](docs/custom-provider.md#api-types) and [OpenAI Compatibility](docs/models.md#openai-compatibility).
- **GLM-5.2 provider improvements** - GLM-5.2 now has corrected Fireworks OpenAI-compatible routing and OpenRouter `xhigh` thinking support, improving `/model` behavior and high-effort reasoning for GLM-5.2 users. See [Model Options](docs/usage.md#model-options).
### Added
- Added inherited configurable `chat-template` thinking support for OpenAI-compatible providers that use `chat_template_kwargs`, such as DeepSeek models behind vLLM ([#5673](https://github.com/earendil-works/pi/issues/5673)).
### Fixed
- Fixed inherited Fireworks GLM-5.2 metadata to use the OpenAI-compatible Chat Completions endpoint with `reasoning_effort` support ([#5923](https://github.com/earendil-works/pi/issues/5923)).
- Fixed same-directory session switches to reuse imported extension modules while preserving fresh extension instances and lifecycle events ([#5905](https://github.com/earendil-works/pi/issues/5905)).
- Fixed deep session branches taking quadratic time to build context or branch paths ([#5909](https://github.com/earendil-works/pi/issues/5909)).
- Fixed inherited OpenRouter GLM-5.2 metadata to expose `xhigh` reasoning and send OpenRouter's native `xhigh` effort ([#5770](https://github.com/earendil-works/pi/issues/5770)).
- Fixed inherited Markdown streaming code fence rendering so partial closing fences no longer make code blocks shrink or flicker while content streams ([#5846](https://github.com/earendil-works/pi/pull/5846) by [@xl0](https://github.com/xl0)).
- Fixed fuzzy `edit` matches to preserve untouched line blocks instead of rewriting the whole file through normalized content ([#5899](https://github.com/earendil-works/pi/issues/5899)).
- Fixed bash commands through legacy WSL `bash.exe` to pass scripts over stdin so shell variables expand in the target bash ([#5893](https://github.com/earendil-works/pi/issues/5893)).
- Fixed `/model` to hide GitHub Copilot models that are unavailable to the authenticated account ([#5897](https://github.com/earendil-works/pi/issues/5897)).
- Fixed `/model` selector search to rank exact provider-prefixed matches before proxy-provider model ID matches ([#5892](https://github.com/earendil-works/pi/issues/5892)).
## [0.79.8] - 2026-06-19
### 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](../ai/README.md#base-entry-point) and [`pi-agent-core` Base Entry Point](../agent/README.md#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](docs/providers.md#api-keys) and [Environment Variables](docs/usage.md#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](docs/rpc.md#compact) and [compaction events](docs/rpc.md#compaction_start--compaction_end).
- **OpenRouter Fusion alias** - `openrouter/fusion` is available as a built-in OpenRouter model alias. See [API Keys](docs/providers.md#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](https://github.com/earendil-works/pi/pull/5348) by [@FredKSchott](https://github.com/FredKSchott)).
- Added inherited Mistral prompt caching using the pi session ID as `prompt_cache_key`, including cached-token usage and cost accounting ([#5854](https://github.com/earendil-works/pi/issues/5854)).
- Added estimated post-compaction token counts to compact results and compaction events ([#5877](https://github.com/earendil-works/pi/issues/5877)).
- Added the inherited OpenRouter Fusion alias as `openrouter/fusion` ([#5866](https://github.com/earendil-works/pi/pull/5866) by [@dannote](https://github.com/dannote)).
### Fixed
- Updated vulnerable runtime dependencies, including `undici` and the packaged `protobufjs` transitive dependency.
- Fixed compaction to refuse sessions with no eligible messages instead of producing empty summaries ([#4811](https://github.com/earendil-works/pi/issues/4811)).
- Fixed successful overflow-triggered auto-compaction to avoid retrying completed assistant responses ([#5720](https://github.com/earendil-works/pi/issues/5720)).
## [0.79.7] - 2026-06-18
### New Features
- **Automatic theme mode** - `/settings` can choose separate light and dark themes and follow terminal color-scheme changes. See [Selecting a Theme](docs/themes.md#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](docs/packages.md#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`](docs/extensions.md#ctxcwd) and [SDK Exports](docs/sdk.md#exports).
- **Warp inline images** - Warp terminals now get inline image rendering through Kitty graphics detection. See [Image](docs/tui.md#image).
### Added
- Added automatic theme mode so `/settings` can use separate light and dark themes and follow terminal color-scheme changes ([#5874](https://github.com/earendil-works/pi/pull/5874)).
- Added inherited Warp terminal image capability detection so inline images render through Warp's Kitty graphics support ([#5841](https://github.com/earendil-works/pi/pull/5841) by [@dodiego](https://github.com/dodiego)).
- Exported `CONFIG_DIR_NAME` from the coding-agent public API so extensions can resolve project config paths without hardcoding `.pi` ([#5869](https://github.com/earendil-works/pi/pull/5869) by [@xl0](https://github.com/xl0)).
- Exported edit diff helpers (`generateDiffString`, `generateUnifiedPatch`, and `EditDiffResult`) from the public API for extensions that need edit-style diffs ([#5756](https://github.com/earendil-works/pi/pull/5756) by [@xl0](https://github.com/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.
### Fixed
- Fixed RPC unknown-command errors to include the request id so clients do not hang waiting for a response ([#5868](https://github.com/earendil-works/pi/issues/5868)).
- Fixed `/model` autocomplete and model selection searches to match provider/model queries regardless of whether the provider or model token is typed first.
- Fixed the tree navigator to horizontally pan deep entries so the selected item remains readable ([#5830](https://github.com/earendil-works/pi/issues/5830)).
## [0.79.6] - 2026-06-16
### Fixed
- Fixed HTTP dispatcher configuration to preserve a caller's deliberate `fetch` override instead of reinstalling the undici global fetch over it.
- Fixed inherited OpenCode Go DeepSeek V4 thinking-off requests to send the provider's `thinking: { type: "disabled" }` compatibility parameter.
## [0.79.5] - 2026-06-16
### New Features
- **Provider-scoped API key environments** - `auth.json` API key entries can now include `env` overrides for provider-specific Cloudflare, Azure OpenAI, Google Vertex, Amazon Bedrock, cache retention, and proxy settings without changing the project shell. See [Auth File](docs/providers.md#auth-file).
- **Global HTTP proxy setting** - Configure `httpProxy` once in global settings to apply `HTTP_PROXY` and `HTTPS_PROXY` to Pi-managed HTTP clients. See [Network](docs/settings.md#network).
- **Vercel AI Gateway attribution** - Vercel AI Gateway requests now include Pi attribution headers by default. See [API Keys](docs/providers.md#api-keys).
### Added
- Added Vercel AI Gateway request attribution headers (`http-referer` and `x-title`) for Vercel AI Gateway models ([#5798](https://github.com/earendil-works/pi/pull/5798) by [@rwachtler](https://github.com/rwachtler)).
- 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](https://github.com/earendil-works/pi/issues/5790)).
- Added `auth.json` API key `env` values so provider-specific environment overrides can be scoped to Pi and propagated to inherited provider configuration ([#5728](https://github.com/earendil-works/pi/issues/5728)).
### Changed
- Updated the vendored Markdown parser used by HTML session exports to `marked` 18.0.5.
### Fixed
- Fixed inherited OpenAI Responses streaming to tolerate null message content from OpenAI-compatible servers before tool calls ([#5819](https://github.com/earendil-works/pi/issues/5819)).
- Fixed inherited OpenCode DeepSeek V4 thinking requests to avoid sending both `thinking` and `reasoning_effort` ([#5818](https://github.com/earendil-works/pi/issues/5818)).
- Fixed device-code login to stop opening the browser automatically.
- Fixed inherited editor Cursor Up handling so non-empty drafts jump to the start of the line before browsing input history ([#5789](https://github.com/earendil-works/pi/pull/5789) by [@4h9fbZ](https://github.com/4h9fbZ)).
- Fixed inherited Z.AI GLM-5.2 thinking requests to send `reasoning_effort` with the provider's `high`/`max` effort mapping ([#5770](https://github.com/earendil-works/pi/issues/5770)).
- Fixed successful `pi update` on Windows to exit naturally instead of calling `process.exit(0)`, avoiding a Node.js/libuv assertion after version-check network requests ([#5805](https://github.com/earendil-works/pi/issues/5805)).
- Fixed inherited Google and `google-vertex` Gemini model metadata to map `latest` aliases to the current models, add Gemini 3.5 Flash for Vertex, correct Gemini 2.5 Flash Vertex cache pricing, and remove shut-down Vertex preview models ([#5761](https://github.com/earendil-works/pi/issues/5761)).
- Fixed the session selector to stay open and show the all-sessions empty state when both current-folder and all-scope session lists are empty ([#5747](https://github.com/earendil-works/pi/issues/5747)).
- Fixed inherited Moonshot AI China model metadata to include Kimi K2.7 Code, and omitted unsupported thinking-off payloads for Kimi K2.7 Code models ([#5760](https://github.com/earendil-works/pi/issues/5760)).
## [0.79.4] - 2026-06-15
### New Features
- **Automatic first-run theme selection** - pi detects the terminal background on first run and defaults to the `dark` or `light` theme. See [Selecting a Theme](docs/themes.md#selecting-a-theme).
- **Standalone binary integrity checksums** - GitHub release assets now include `SHA256SUMS` files for verifying standalone binary downloads. See [Quickstart Install](docs/quickstart.md#install).

- Added `SHA256SUMS` integrity files to standalone binary GitHub release assets ([#5739](https://github.com/earendil-works/pi/issues/5739)).
- Added first-run interactive theme detection from the terminal background ([#5385](https://github.com/earendil-works/pi/pull/5385) by [@vegarsti](https://github.com/vegarsti)).
### Fixed
- Fixed bash tool output collection to keep draining stdout/stderr after the child exits while descendants still write, avoiding truncated late output ([#5753](https://github.com/earendil-works/pi/pull/5753) by [@Mearman](https://github.com/Mearman)).
- Fixed `/tree` help rendering to show compact wrapped controls instead of truncating them on narrow terminals ([#5055](https://github.com/earendil-works/pi/issues/5055)).
- Fixed SIGTERM/SIGHUP interactive shutdown to keep signal handlers installed until terminal cleanup completes, preventing `signal-exit` from re-sending the signal and leaving the terminal in raw/Kitty keyboard mode ([#5724](https://github.com/earendil-works/pi/issues/5724)).
- Fixed extensions documentation to clarify that `pi.getActiveTools()` returns active tool names while `pi.getAllTools()` returns tool metadata ([#5729](https://github.com/earendil-works/pi/issues/5729)).
- Fixed question and questionnaire extension examples to wrap long prompt, option, and help text instead of truncating it ([#5708](https://github.com/earendil-works/pi/pull/5708) by [@xl0](https://github.com/xl0)).
- Fixed package commands such as `pi list`, `pi install`, and `pi update` to terminate after completing even if an extension leaves background handles open ([#5687](https://github.com/earendil-works/pi/issues/5687)).
- Fixed `pi update` for pnpm global installs whose configured `global-bin-dir` no longer matches the active pnpm home ([#5689](https://github.com/earendil-works/pi/issues/5689)).
- Fixed npm package specs that use ranges or tags (for example `@^1.2.7`) so installed package resources still load instead of being treated as mismatched exact pins ([#5695](https://github.com/earendil-works/pi/issues/5695)).
- Fixed inherited Anthropic 1-hour prompt-cache write cost accounting to price 1-hour cache writes at 2x input instead of the 5-minute cache-write rate ([#5738](https://github.com/earendil-works/pi/pull/5738) by [@theBucky](https://github.com/theBucky)).
- Fixed inherited GitHub Copilot Claude adaptive-thinking effort metadata to match manually checked Copilot model capabilities ([#4637](https://github.com/earendil-works/pi/issues/4637)).
- Fixed inherited OpenCode/OpenCode Go completion model metadata to omit long-retention cache fields for routes that reject `prompt_cache_retention` ([#5702](https://github.com/earendil-works/pi/issues/5702)).
- Fixed inherited overlay compositing over CJK wide characters so borders stay aligned when an overlay starts inside a full-width cell ([#5297](https://github.com/earendil-works/pi/issues/5297)).
- Fixed inherited WezTerm inline Kitty image rendering during full redraw fallbacks so image padding rows are reserved before the placement is drawn without regressing tall-image placement ([#5618](https://github.com/earendil-works/pi/issues/5618), [#4415](https://github.com/earendil-works/pi/issues/4415)).
- Fixed custom provider config so plain uppercase API key and header values remain literals instead of being treated as legacy environment references; use explicit `$ENV_VAR` syntax for environment variables ([#5661](https://github.com/earendil-works/pi/issues/5661)).
## [0.79.3] - 2026-06-13
### Fixed
- Fixed inherited OpenAI GPT-5.4/GPT-5.5 and OpenAI Codex GPT-5.4/GPT-5.4 mini/GPT-5.5 context window metadata to use the observed 272k-token Codex backend limit, avoiding a billing hazard from prompts above Codex's accepted limit (reported by [@trethore](https://github.com/trethore)).
## [0.79.2] - 2026-06-12
### New Features
- **Clearer Bedrock validation guidance** - Amazon Bedrock data retention validation errors now link to AWS data retention documentation. See [Amazon Bedrock](docs/providers.md#amazon-bedrock).
### Added
- Added an experimental first-time setup flow behind `PI_EXPERIMENTAL=1` that asks for a dark/light theme choice (preselecting the detected appearance) and opt-in analytics data sharing on first launch with the default agent directory; opting in stores a `trackingId` in `settings.json` ([#5587](https://github.com/earendil-works/pi/pull/5587) by [@vegarsti](https://github.com/vegarsti)).
- Added AWS data retention documentation links to inherited Amazon Bedrock unsupported data retention mode validation errors ([#5561](https://github.com/earendil-works/pi/pull/5561) by [@unexge](https://github.com/unexge)).
### Fixed
- Fixed project trust detection to ignore global `~/.pi/agent` state when running from `$HOME`, and made `pi update` use only saved or explicit project trust without prompting ([#5619](https://github.com/earendil-works/pi/issues/5619)).
- Fixed experimental first-time setup to skip forked sessions instead of rerunning the setup prompts ([#5627](https://github.com/earendil-works/pi/pull/5627) by [@vegarsti](https://github.com/vegarsti)).
- Fixed inherited OpenAI-compatible context overflow detection for parenthesized `maximum context length (N)` errors ([#5677](https://github.com/earendil-works/pi/issues/5677)).
- 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 match current OpenAI limits ([#5644](https://github.com/earendil-works/pi/issues/5644)).
- Fixed inherited Anthropic refusal stops to preserve provider `stop_details` explanations in error messages ([#5666](https://github.com/earendil-works/pi/pull/5666) by [@rwachtler](https://github.com/rwachtler)).
- Increased the inherited OpenAI Codex Responses SSE response-header timeout to 20 seconds to reduce false-positive stalls while retaining the bounded wait introduced for zero-event hangs ([#4945](https://github.com/earendil-works/pi/issues/4945)).
- Fixed inherited Claude Fable 5 thinking-off requests to omit Anthropic's unsupported `thinking.type: "disabled"` payload ([#5567](https://github.com/earendil-works/pi/pull/5567) by [@tmustier](https://github.com/tmustier)).
- Fixed inherited late tool progress callbacks after tool settlement to be ignored instead of emitting stale `tool_execution_update` events ([#5573](https://github.com/earendil-works/pi/issues/5573)).
- Fixed inherited user-message transcript rendering so standalone `+` messages no longer render as `-` ([#5657](https://github.com/earendil-works/pi/issues/5657)).
- Fixed inherited slash-separated fuzzy queries so provider/model completions remain matchable after insertion.
- Fixed inherited WezTerm inline Kitty image rendering so reserved row clears do not erase all but the top strip of tool image previews ([#5618](https://github.com/earendil-works/pi/issues/5618)).
- Fixed inherited editor wrapping for CJK text to break at character boundaries instead of leaving large trailing gaps ([#5585](https://github.com/earendil-works/pi/pull/5585) by [@haoqixu](https://github.com/haoqixu)).
- Fixed inherited loose Markdown list rendering to preserve blank-line separation between list items ([#5562](https://github.com/earendil-works/pi/pull/5562) by [@Perlence](https://github.com/Perlence)).
- Fixed `--model` resolution for authenticated custom model IDs whose slash prefix matches an unauthenticated built-in provider ([#5643](https://github.com/earendil-works/pi/issues/5643)).
- Fixed `/fork` to keep session parent chains connected when the forked path contains labels ([#5669](https://github.com/earendil-works/pi/issues/5669)).
- Fixed `/share` and `/export` HTML exports to use the active fallback theme when the configured custom theme no longer exists ([#5596](https://github.com/earendil-works/pi/issues/5596)).
- Fixed custom fallback model IDs with `:<thinking>` suffixes to preserve the requested thinking level when the provider template model does not advertise reasoning ([#5560](https://github.com/earendil-works/pi/pull/5560) by [@haoqixu](https://github.com/haoqixu)).
