# Changelog ## [0.83.0] - 2026-07-29 ### New Features - **Credential export for external clients** — `pi auth print-api-key` and `pi auth print-bearer-token` export configured credentials with automatic OAuth refresh and minimum-validity enforcement. - **Headless OpenRouter sign-in** — Complete `/login` over SSH by pasting the redirect URL or authorization code when the loopback callback is unavailable. See [OpenRouter](docs/providers.md#openrouter). - **Claude Opus 5 on GitHub Copilot** — Use Claude Opus 5 through GitHub Copilot with adaptive thinking and a 1M context window. See [GitHub Copilot](docs/providers.md#github-copilot). ### Breaking Changes - Upgraded bundled TypeBox aliases to 1.3.7, removing deprecated APIs including `Type.Base`, `Type.Awaited`, `Type.Promise`, `Type.AsyncIterator`, `Type.Iterator`, `Type.Options`, and `Value.Mutate`, while fixing compiled validation of nullable array tool arguments. Extensions using removed APIs must migrate to supported TypeBox APIs. See [Package Dependencies](docs/packages.md#dependencies) ([#7243](https://github.com/earendil-works/pi/pull/7243) by [@petrroll](https://github.com/petrroll)). ### Added - Added `pi auth print-api-key` and `pi auth print-bearer-token` commands for exporting configured credentials to external clients, including automatic OAuth refresh and configurable minimum token validity ([#7168](https://github.com/earendil-works/pi/pull/7168)). - Exposed the session's resolved model scope as `ctx.scopedModels` to extensions. See [Extension Context](docs/extensions.md#ctxmodelregistry--ctxmodel--ctxthinkinglevel--ctxscopedmodels) ([#7191](https://github.com/earendil-works/pi/pull/7191) by [@pungggi](https://github.com/pungggi), [#7215](https://github.com/earendil-works/pi/pull/7215)). - Added inherited per-request `fetch` injection for supported text and image provider transports. - Added the inherited `"pending"` stop reason for partial streaming messages. See [Custom Provider Stream Pattern](docs/custom-provider.md#stream-pattern) ([#7151](https://github.com/earendil-works/pi/pull/7151) by [@lucasmeijer](https://github.com/lucasmeijer)). - Added inherited raw provider stop reasons across Google, Anthropic, Amazon Bedrock, Mistral, and OpenAI streams; unmapped terminal reasons now surface as provider errors instead of successful stops ([#7272](https://github.com/earendil-works/pi/pull/7272)). - Added manual redirect URL and authorization-code entry to OpenRouter login for remote and headless environments. See [OpenRouter](docs/providers.md#openrouter) ([#7114](https://github.com/earendil-works/pi/pull/7114) by [@rgarcia](https://github.com/rgarcia)). - Added inherited Claude Opus 5 support for GitHub Copilot with adaptive thinking and a 1M context window.

See [Context Files](docs/usage.md#context-files) ([#7221](https://github.com/earendil-works/pi/pull/7221) by [@arajkumar](https://github.com/arajkumar)). - Fixed llama.cpp streamed responses reporting zero token usage and leaving session context accounting empty. See [llama.cpp](docs/llama-cpp.md) ([#7258](https://github.com/earendil-works/pi/pull/7258) by [@SteveImmanuel](https://github.com/SteveImmanuel)). - Fixed session replacement and committed tree navigation during an active response to abort and persist the outgoing turn instead of leaving dangling tool calls. See [Sessions](docs/usage.md#sessions) ([#7022](https://github.com/earendil-works/pi/pull/7022) by [@tmustier](https://github.com/tmustier)). - Fixed failed Git package installs leaving partial directories that blocked clean retries. See [Install and Manage](docs/packages.md#install-and-manage) ([#7210](https://github.com/earendil-works/pi/pull/7210) by [@haoqixu](https://github.com/haoqixu)). - Fixed the `/model` selector retaining a stale selection while filtering instead of highlighting the top match ([#7211](https://github.com/earendil-works/pi/pull/7211) by [@christianbasch](https://github.com/christianbasch)). - Fixed direct RPC bash commands bypassing extension `user_bash` handlers. See [User Bash Events](docs/extensions.md#user-bash-events) ([#7214](https://github.com/earendil-works/pi/pull/7214)). - Fixed skills, prompts, and themes losing package source metadata after extensions reload resources. See [Resource Events](docs/extensions.md#resource-events) ([#6968](https://github.com/earendil-works/pi/issues/6968)). - Fixed cancellation of concurrently running user bash commands so every active command is aborted ([#7103](https://github.com/earendil-works/pi/pull/7103) by [@yzhg1983](https://github.com/yzhg1983)). - Fixed duplicate messages appearing when extensions switch sessions during interactive startup ([#7110](https://github.com/earendil-works/pi/pull/7110) by [@yzhg1983](https://github.com/yzhg1983)). - Fixed inherited Qwen Token Plan reasoning models to send their service-specific thinking controls and supported reasoning-effort levels ([#6951](https://github.com/earendil-works/pi/issues/6951), [#6998](https://github.com/earendil-works/pi/issues/6998)). - Fixed inherited Z.AI output limits being sent through an unsupported parameter. See [Providers](docs/providers.md) ([#7174](https://github.com/earendil-works/pi/pull/7174) by [@HyeokjaeLee](https://github.com/HyeokjaeLee)). - Fixed explicitly configured Amazon Bedrock profiles being overridden by ambient AWS access keys.

See [Providers](docs/providers.md#api-keys). - **Anthropic gateway bearer auth** — `ANTHROPIC_AUTH_TOKEN` authenticates against Anthropic-compatible gateways that require `Authorization: Bearer`, including compaction and branch summaries. See [Environment Variables or Auth File](docs/providers.md#environment-variables-or-auth-file). - **Faster, more resilient model catalogs** — pi.dev catalogs revalidate with `If-None-Match` so unchanged providers answer with an empty `304`, and llama.cpp models stay listed across restarts. See [llama.cpp](docs/llama-cpp.md). ### Added - Exposed the `outputPad` setting to custom message renderers. See [Extensions](docs/extensions.md) ([#7045](https://github.com/earendil-works/pi/pull/7045) by [@xl0](https://github.com/xl0)). - Added inherited `ANTHROPIC_AUTH_TOKEN` bearer authentication for Anthropic-compatible gateways.

See [llama.cpp](docs/llama-cpp.md) ([#7072](https://github.com/earendil-works/pi/pull/7072) by [@davidbrai](https://github.com/davidbrai)). ## [0.82.0] - 2026-07-24 ### New Features - **Constrained tool sampling** — Tools can prefer or require strict JSON Schema sampling or use OpenAI Lark/regex grammars, with model capability metadata preventing unsupported requests. See [Constrained Sampling for Tools](../ai/README.md#constrained-sampling-for-tools). - **OpenRouter and Kimi Code sign-in** — Use `/login` to authorize OpenRouter or a Kimi Code subscription without manually configuring API keys. See [OpenRouter](docs/providers.md#openrouter). - **Session-aware, streaming bash integrations** — Bash tools receive current session/model metadata, while direct RPC bash commands stream correlated output. See [Bash Tool Session Environment](docs/environment-variables.md#bash-tool-session-environment) and [RPC bash events](docs/rpc.md#bash_execution_update). ### Added - Added inherited `Tool.constrainedSampling` with strict JSON Schema (`prefer`/`require`) and OpenAI Lark/regex grammar variants across OpenAI, Anthropic, Amazon Bedrock, Google Gemini, and Mistral. See [Constrained Sampling for Tools](../ai/README.md#constrained-sampling-for-tools). - Added inherited `supportsGrammarTools` and `supportsStrictTools` compatibility flags, expanded `supportsStrictMode` coverage, and generated model capability metadata to gate constrained sampling. - Added inherited Kimi Code subscription OAuth login for the Kimi For Coding provider, including device authorization and automatic token refresh ([#6935](https://github.com/earendil-works/pi/pull/6935) by [@zaycruz](https://github.com/zaycruz)). - Added inherited OpenRouter OAuth PKCE login through `/login`, minting a user-controlled API key.

See [Bash Tool Session Environment](docs/environment-variables.md#bash-tool-session-environment). - Added streaming `bash_execution_update` events for direct RPC bash commands, correlated with request IDs. See [RPC bash events](docs/rpc.md#bash_execution_update) ([#6971](https://github.com/earendil-works/pi/pull/6971) by [@ananthakumaran](https://github.com/ananthakumaran)). ### Changed - Changed inherited generated model catalogs to expose only provider-verified reasoning effort levels from models.dev ([#6928](https://github.com/earendil-works/pi/pull/6928) by [@davidbrai](https://github.com/davidbrai)). ### Fixed - Fixed inherited DNS lookup failures such as `getaddrinfo`, `ENOTFOUND`, and `EAI_AGAIN` to trigger automatic assistant retries ([#6946](https://github.com/earendil-works/pi/pull/6946) by [@christianklotz](https://github.com/christianklotz)). - Fixed inherited OpenRouter Anthropic cache breakpoints to advance through tool results and enabled cache control for `~anthropic/*-latest` aliases ([#6941](https://github.com/earendil-works/pi/pull/6941) by [@mteam88](https://github.com/mteam88)). - Fixed inherited OpenAI Codex WebSocket sessions to retry once without a missing previous-response continuation after `previous_response_not_found` errors ([#6955](https://github.com/earendil-works/pi/pull/6955) by [@davidbrai](https://github.com/davidbrai)). - Fixed TUI debug and crash logs to respect custom agent directories instead of always writing under `~/.pi/agent` ([#6958](https://github.com/earendil-works/pi/pull/6958) by [@davidbrai](https://github.com/davidbrai)). - Fixed slow Ctrl+G external-editor startup when the system temporary directory contains many entries ([#6903](https://github.com/earendil-works/pi/pull/6903) by [@christianklotz](https://github.com/christianklotz)). - Fixed startup resource display to preserve relative paths for sibling npm extensions loaded by a package ([#6964](https://github.com/earendil-works/pi/pull/6964) by [@davidbrai](https://github.com/davidbrai)). - Fixed compaction and branch-summary requests to use fresh routing session IDs with prompt caching disabled where supported ([#6618](https://github.com/earendil-works/pi/pull/6618) by [@tmustier](https://github.com/tmustier)). - Fixed explicit self-updates when `PI_SKIP_VERSION_CHECK` is set ([#6977](https://github.com/earendil-works/pi/issues/6977)). - Fixed scoped model IDs containing brackets to resolve as literal exact matches before glob matching ([#6210](https://github.com/earendil-works/pi/issues/6210)). - Fixed inherited OpenAI and Anthropic provider retry waits to honor abort signals and configured delay limits ([#6980](https://github.com/earendil-works/pi/pull/6980) by [@petrroll](https://github.com/petrroll)). - Fixed fresh installs from preferring bundled model catalogs over newer remote catalogs because package file mtimes were newer ([#7016](https://github.com/earendil-works/pi/pull/7016) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited editor scroll indicators overflowing narrow terminals ([#7015](https://github.com/earendil-works/pi/pull/7015) by [@christianklotz](https://github.com/christianklotz)). - Fixed llama.cpp models to use the loaded context window as their output token limit instead of capping it at 16K ([#7034](https://github.com/earendil-works/pi/pull/7034) by [@christianklotz](https://github.com/christianklotz)). - Fixed release source archives to include the generated provider model data used to build standalone binaries. - Updated the packaged `protobufjs` dependency to 7.6.5 to address GHSA-j3f2-48v5-ccww ([#7005](https://github.com/earendil-works/pi/issues/7005)). - Fixed `/copy` on Wayland to fall back to X11 or OSC 52 when `wl-copy` fails ([#7009](https://github.com/earendil-works/pi/pull/7009) by [@rkfshakti](https://github.com/rkfshakti)). - Fixed `/model` to reload updated `models.json` configuration when opening the model picker ([#6999](https://github.com/earendil-works/pi/issues/6999)). ## [0.81.1] - 2026-07-21 ### New Features - **Verifiable release source archives** — GitHub releases now include deterministic, checksummed source archives with instructions for rebuilding standalone binaries. See [Building standalone binaries from release source](../../README.md#building-standalone-binaries-from-release-source). - **Resilient compaction and branch summaries** — Transient provider failures now follow the configured retry policy, with retry lifecycle events available to interactive, JSON, RPC, and SDK consumers. See [Compaction & Branch Summarization](docs/compaction.md) and [RPC retry events](docs/rpc.md#summarization_retry_scheduled--summarization_retry_attempt_start--summarization_retry_finished). ### Added - Added deterministic, checksummed source archives to GitHub releases with documented standalone binary rebuild instructions ([#6913](https://github.com/earendil-works/pi/pull/6913) by [@christianklotz](https://github.com/christianklotz)). ### Fixed - Fixed compaction and branch summarization to retry transient provider failures using the configured retry policy, with retry lifecycle events exposed to interactive, JSON, RPC, and SDK consumers ([#6901](https://github.com/earendil-works/pi/pull/6901) by [@davidbrai](https://github.com/davidbrai)). - Fixed interactive startup waiting for background model catalog refresh while computing the footer provider count. - Restored the default stream fallback for extensions using the pre-0.81 agent-core API ([#6915](https://github.com/earendil-works/pi/issues/6915)). - Fixed inherited Kimi K3 models from Moonshot AI and Moonshot AI China to use the OpenAI thinking format and expose reasoning effort support. ## [0.81.0] - 2026-07-21 ### New Features - **Local llama.cpp model management** — Connect to a llama.cpp router, search and download Hugging Face models, and explicitly load or unload models with live progress. See [llama.cpp](docs/llama-cpp.md). - **Full provider extensions** — Extensions can register complete pi-ai providers with authentication, model refresh, filtering, and custom streaming. See [Register New Provider](docs/custom-provider.md#register-new-provider). - **Qwen Token Plan providers** — Use the built-in international and China subscription providers with regional endpoints and API-key authentication. See [API Keys](docs/providers.md#api-keys). - **Expanded usage accounting** — Tool, compaction, and branch-summary usage is persisted and included in session totals. See [Compaction & Branch Summarization](docs/compaction.md). ### Added - Added Qwen Token Plan and Qwen Token Plan China to built-in provider setup, default model resolution, and provider documentation ([#6858](https://github.com/earendil-works/pi/pull/6858) by [@QuintinShaw](https://github.com/QuintinShaw)). - Added the `get_available_thinking_levels` RPC command and `RpcClient.getAvailableThinkingLevels()` method ([#6865](https://github.com/earendil-works/pi/pull/6865) by [@cristinaponcela](https://github.com/cristinaponcela)). - Exported message and tool execution lifecycle event types from the package root ([#6772](https://github.com/earendil-works/pi/pull/6772) by [@davidbrai](https://github.com/davidbrai)). - Added built-in llama.cpp router support with `/login` connection setup and `/llama` Hugging Face model search and downloads, explicit loading, unloading, and live progress. See [llama.cpp](docs/llama-cpp.md). - Added extension registration for complete pi-ai providers, including native authentication, model refresh, filtering, and streaming behavior. - Added usage accounting for tools, compaction, and branch summaries in persisted sessions, footer totals, and session statistics ([#6671](https://github.com/earendil-works/pi/pull/6671) by [@davidbrai](https://github.com/davidbrai)). ### Fixed - Updated the packaged `brace-expansion` dependency to 5.0.7 ([#6896](https://github.com/earendil-works/pi/pull/6896) by [@davidbrai](https://github.com/davidbrai)). - Fixed persisted remote model catalogs from overriding newer bundled catalogs after an upgrade. - Fixed inherited stored API-key credentials to apply their provider-scoped `env` values, including Amazon Bedrock profiles ([#6864](https://github.com/earendil-works/pi/pull/6864) by [@cristinaponcela](https://github.com/cristinaponcela)). - Fixed inherited OpenAI-compatible cross-provider replay to keep tool call IDs unique when multiple calls share a provider call ID ([#6854](https://github.com/earendil-works/pi/pull/6854) by [@cristinaponcela](https://github.com/cristinaponcela)). - Fixed inherited Kimi K3 thinking levels to expose low, high, and max, and normalized the `k2p7` alias to `kimi-for-coding`. - Fixed inherited OpenCode Go models routed through the OpenAI Responses API. - Fixed inherited `pi-ai` package metadata to avoid repeated consumer lockfile changes ([#6812](https://github.com/earendil-works/pi/pull/6812) by [@jmfederico](https://github.com/jmfederico)). - Fixed inherited terminal shutdown to clear the editor's inverted software cursor before restoring the hardware cursor ([#6790](https://github.com/earendil-works/pi/pull/6790) by [@dam9000](https://github.com/dam9000)). - Fixed inherited ANSI-aware text wrapping to recognize CRLF and CR line endings while preserving styles ([#6764](https://github.com/earendil-works/pi/pull/6764) by [@xz-dev](https://github.com/xz-dev)). - Fixed inherited editor paste registry corruption after deleting and undoing paste markers, preventing literal or mismatched paste markers in submitted prompts ([#6844](https://github.com/earendil-works/pi/issues/6844)). - Fixed sessionless OpenAI Codex WebSocket requests to use UUIDv7 request IDs ([#6834](https://github.com/earendil-works/pi/pull/6834) by [@xl0](https://github.com/xl0)). - Fixed inherited GPT-5.6 Codex models to default to the 272K context window, avoiding automatic long-context pricing ([#6853](https://github.com/earendil-works/pi/pull/6853) by [@aadishv](https://github.com/aadishv)). - Fixed messages queued during compaction to preserve steering and follow-up delivery behavior ([#6730](https://github.com/earendil-works/pi/pull/6730) by [@dannote](https://github.com/dannote)). - Fixed read tool errors being syntax-highlighted as if they were file contents ([#6731](https://github.com/earendil-works/pi/pull/6731) by [@dannote](https://github.com/dannote)). - Fixed llama.cpp router download progress updates and removed redundant wording from model action confirmations. - Moved automatic model catalog network refresh out of startup initialization and into the running interactive and RPC modes. - Fixed persisted sessions being read and parsed twice when opened, reducing startup latency for large sessions ([#6793](https://github.com/earendil-works/pi/issues/6793)). - Fixed prompt-template defaults for all arguments (`${@:-default}` and `${ARGUMENTS:-default}`) ([#6695](https://github.com/earendil-works/pi/issues/6695)). - Fixed obsolete custom UI, custom tool, and custom editor examples in the extension documentation ([#6735](https://github.com/earendil-works/pi/issues/6735)). - Fixed Kimi Coding sessions to show API-equivalent implied costs with the subscription indicator. - Fixed OpenAI Responses early stream endings to trigger automatic retry instead of ending the agent run ([#6727](https://github.com/earendil-works/pi/issues/6727)). ## [0.80.10] - 2026-07-16 ### New Features - **Kimi Coding thinking compatibility** — Kimi Coding models now use adaptive thinking correctly; K3 exposes its supported `max` level and supports replaying empty-signature thinking blocks. See [Kimi For Coding setup](docs/providers.md#api-keys) and [Model Options](docs/usage.md#model-options). ### Fixed - Fixed inherited Kimi Coding requests to use Anthropic adaptive thinking effort without token budgets, and enabled empty thinking signatures for K3 and `kimi-for-coding`. - Fixed inherited Kimi K3 pricing metadata for Moonshot AI and Moonshot AI China. - Fixed inherited Kimi Coding K3 thinking-level metadata to expose only the supported `max` level ([#6737](https://github.com/earendil-works/pi/issues/6737)). - Fixed inherited catalog generation restoring xAI models removed in 0.80.9 ([#6736](https://github.com/earendil-works/pi/issues/6736)). ## [0.80.9] - 2026-07-16 ### New Features - **Kimi K3 and deferred tool loading** — Use Kimi K3 across built-in providers, including progressive extension tool activation through Kimi’s native protocol. See [Dynamic Tool Loading](docs/extensions.md#dynamic-tool-loading), [OpenAI Compatibility](docs/models.md#openai-compatibility), and the [`kimi-deferred-tools.ts`](examples/extensions/kimi-deferred-tools.ts) example. ### Added - Added inherited Kimi K3 support for Kimi Coding, Moonshot AI, Moonshot AI China, OpenRouter, and Vercel AI Gateway. - Added Kimi deferred tool loading for extension-driven tool activation. See [Dynamic Tool Loading](docs/extensions.md#dynamic-tool-loading), [OpenAI Compatibility](docs/models.md#openai-compatibility), and the [`kimi-deferred-tools.ts`](examples/extensions/kimi-deferred-tools.ts) example. ### Changed - Changed xAI login to use a prefilled device-authorization link labeled “Sign in with SuperGrok or X Premium,” and changed the default xAI model to Grok 4.5 ([#6734](https://github.com/earendil-works/pi-mono/pull/6734) by [@Jaaneek](https://github.com/Jaaneek)). ### Fixed - Fixed inherited Kimi K3 output limits for Vercel AI Gateway and OpenRouter models. - Fixed cloning or forking a session before its first assistant response to explain that the session must be saved first. ### Removed - Removed Grok 3, Grok 3 Fast, Grok 4.20 variants, and Grok Code Fast 1 from the built-in xAI model catalog ([#6734](https://github.com/earendil-works/pi-mono/pull/6734) by [@Jaaneek](https://github.com/Jaaneek)). ## [0.80.8] - 2026-07-16 ### New Features - **Unified model runtime and provider authentication** — `ModelRuntime` centralizes model configuration, provider-owned `/login`, and dynamic provider catalogs. See [Providers](docs/providers.md). - **Live model catalog refresh** — `/model` refreshes configured providers in the background, and `pi update --models` forces an immediate refresh. See [Install and Manage](docs/packages.md#install-and-manage). - **xAI device-code OAuth and Grok 4.5 Responses support** — Sign in to xAI with a device code and use Grok 4.5 with low, medium, or high thinking. See [xAI](docs/providers.md#xai-grokx-subscription). ### Breaking Changes - Replaced the SDK's `CreateAgentSessionOptions.authStorage` and `modelRegistry` options with the async `modelRuntime` option. `AuthStorage` and its storage backends are no longer exported; use `ModelRuntime` (or a custom pi-ai `CredentialStore`), or `readStoredCredential()` for one-off reads of auth.json. - Removed redundant `ModelRuntime.getAll()`, `find()`, `getSnapshot()`, and `getAuthOptions()` projections. Use the pi-ai `Models` methods `getModels()`, `getModel()`, `getProviders()`, and `checkAuth()` directly. - Replaced SDK request-auth assembly through `ModelRegistry.getApiKeyAndHeaders()` with `ModelRuntime.getAuth()`. Passing a provider ID returns provider-scoped auth; passing a model also resolves built-in, `models.json`, and extension model headers. - Changed extension-facing `ModelRegistry.refresh()` from synchronous `void` to `Promise<void>` because `models.json` loading is asynchronous. Extensions must await it before making synchronous registry reads. - Moved canonical dynamic catalog refresh to async `ModelRuntime.refresh()`/pi-ai `Models.refresh()`. Legacy extension OAuth `modifyModels` remains supported as a synchronous compatibility projection after credential initialization. ### Added - Added `ModelRuntime` as the canonical async SDK and internal model/auth facade while preserving the synchronous extension-facing `ModelRegistry` API. `ModelRuntime.create()` accepts any pi-ai `CredentialStore` through its `credentials` option. - Added provider-owned `/login` discovery directly from registered pi-ai providers, including ambient auth status and informational links. - Added file-backed dynamic catalogs in `models-store.json`, per-provider pi.dev catalog overlays, and Radius gateway support including offline migration from legacy credential-cached catalogs. - Added extension provider `refreshModels(context)` support for dynamic model discovery with optional provider-controlled persistence. - Added `pi update --models` to force an immediate model catalog refresh without updating pi or extensions. - Added inherited xAI device-code OAuth login and Grok 4.5 OpenAI Responses support, with low, medium, and high thinking levels ([#6651](https://github.com/earendil-works/pi-mono/pull/6651) by [@Jaaneek](https://github.com/Jaaneek)). ### Changed - Changed `ModelRuntime` to compose built-in providers, immutable `models.json` configuration, and extension overlays through ad-hoc pi-ai provider methods. - Changed `ModelRuntime` to own final request assembly: `getAuth(model)` includes configured model headers, stream methods resolve auth once, and `before_provider_headers` runs as the Models-only header transform before provider dispatch. - Changed `/model` to render the current model snapshot immediately, refresh configured providers in the background, and update the open selector with partial results or timeout errors. ### Fixed - Fixed configured-provider catalog refresh to parse pi.dev's model-ID keyed responses, throttle checks to once per four hours, send the versioned pi user agent, treat unimplemented routes as unavailable overlays, and show concise refresh status in `/model`. - Fixed adjacent assistant thinking blocks to render as one thinking section. - Fixed inherited OpenAI Codex session IDs longer than 64 characters to meet the API limit ([#6630](https://github.com/earendil-works/pi-mono/issues/6630)). - Fixed inherited terminal output to normalize tab characters consistently ([#6697](https://github.com/earendil-works/pi-mono/pull/6697) by [@xz-dev](https://github.com/xz-dev)). - Fixed the Windows terminal title after checking npm packages ([#6629](https://github.com/earendil-works/pi-mono/issues/6629)). - Fixed Bun standalone binaries to bundle OAuth adapters for interactive logins. ## [0.80.7] - 2026-07-14 ### Breaking Changes - Removed the `openai-responses` `compat.sendSessionIdHeader` flag from `models.json`. Session-affinity behavior is now controlled by `compat.sessionAffinityFormat` (`"openai"`, `"openai-nosession"`, or `"openrouter"`). Replace `sendSessionIdHeader: false` with `sessionAffinityFormat: "openai-nosession"` ([#6496](https://github.com/earendil-works/pi-mono/pull/6496) by [@petrroll](https://github.com/petrroll)). ### New Features - **Cache-friendly dynamic tool loading** - Extensions can add tools during execution while supported Anthropic and OpenAI Responses models preserve prompt-cache prefixes. See [Dynamic Tool Loading](docs/extensions.md#dynamic-tool-loading). - **Message copy shortcut** - `Ctrl+X` copies the last assistant message in the transcript or the selected message in `/tree`, making older and branched messages directly copyable. See [Display and Message Queue](docs/keybindings.md#display-and-message-queue). - **Fable 5 `xhigh` and `max` thinking** - Native `xhigh` and `max` thinking levels are available across generated provider catalogs. See [Model Options](docs/usage.md#model-options). ### Added - Added cache-friendly dynamic tool loading for extension tools activated by tool results. Supported Anthropic and OpenAI Responses models load definitions where they become available, preserving the cached prompt prefix. See [Dynamic Tool Loading](docs/extensions.md#dynamic-tool-loading) ([#6474](https://github.com/earendil-works/pi-mono/pull/6474)). - Added inherited native `xhigh` and `max` thinking levels for Claude Fable 5 across all generated provider catalogs ([#6490](https://github.com/earendil-works/pi-mono/pull/6490) by [@davidbrai](https://github.com/davidbrai)). - Added `Ctrl+X` to copy the last assistant message, or the selected message in `/tree`. - Added inherited `toolChoice` support for OpenAI and Codex Responses, including required and named tool selection ([#6588](https://github.com/earendil-works/pi-mono/pull/6588) by [@xl0](https://github.com/xl0)). ### Fixed - Fixed inherited OpenRouter model context windows to use the top provider's actual context length ([#6481](https://github.com/earendil-works/pi-mono/pull/6481) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited OpenRouter OpenAI-compatible session IDs to use the `x-session-id` header instead of OpenAI-specific session-affinity fields ([#6496](https://github.com/earendil-works/pi-mono/pull/6496) by [@petrroll](https://github.com/petrroll)). - Fixed `Ctrl+V` to paste clipboard text when the pasteboard does not contain an image. - Fixed `/login amazon-bedrock` to prompt for and save a Bedrock API key instead of only displaying ambient AWS credential setup instructions. - Fixed inherited Amazon Bedrock ambient AWS credentials to keep using SigV4 authentication, including for custom model IDs ([#6532](https://github.com/earendil-works/pi-mono/pull/6532) by [@ribelo](https://github.com/ribelo)). - Fixed inherited Cloudflare Workers AI and AI Gateway authentication to use ambient account and gateway IDs when stored credentials contain only an API key ([#6292](https://github.com/earendil-works/pi-mono/pull/6292) by [@markphelps](https://github.com/markphelps)). - Fixed inherited legacy terminal decoding for Alt+symbol key combinations such as `Alt+,` and `Alt+.` ([#6523](https://github.com/earendil-works/pi-mono/pull/6523) by [@ribelo](https://github.com/ribelo)). - Fixed the GitHub Copilot `mai-code-1-flash-picker` model to route through the `/responses` endpoint ([#6544](https://github.com/earendil-works/pi-mono/pull/6544) by [@petrroll](https://github.com/petrroll)). - Fixed branch summaries to work with providers that use ambient authentication instead of API keys ([#6595](https://github.com/earendil-works/pi-mono/pull/6595) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited Amazon Bedrock errors to report unhandled provider stop reasons instead of only `An unknown error occurred` ([#6598](https://github.com/earendil-works/pi-mono/pull/6598) by [@davidbrai](https://github.com/davidbrai)). - Fixed npm package removal when installed packages have conflicting peer dependencies ([#6604](https://github.com/earendil-works/pi-mono/pull/6604) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited Azure OpenAI Responses reasoning replay when `encrypted_content` appears only in the terminal response event ([#6608](https://github.com/earendil-works/pi-mono/pull/6608) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited Anthropic-compatible proxies that omit `usage` from `message_delta` events ([#6611](https://github.com/earendil-works/pi-mono/pull/6611) by [@davidbrai](https://github.com/davidbrai)). - Fixed inherited OpenCode OpenAI Responses models to omit the unsupported `session-id` header while preserving other cache-affinity data ([#6645](https://github.com/earendil-works/pi-mono/pull/6645) by [@davidbrai](https://github.com/davidbrai)). - Fixed system prompt cache invalidation across dates by removing the current date from the default prompt ([#6621](https://github.com/earendil-works/pi/issues/6621)). ## [0.80.6] - 2026-07-09 ### New Features - **`max` thinking level** - New opt-in thinking level above `xhigh`, natively supported on GPT-5.6 and adaptive Claude models, available across CLI (`--thinking max`), SDK, RPC, and model selection. Custom themes can define `thinkingMax`. See [CLI Reference](docs/usage.md#cli-reference). - **Input-based pricing tiers** - Request-wide input-token pricing tiers for accurate long-context cost accounting (e.g. GPT-5.4/5.5/5.6 long-context rates), also configurable for custom models in `models.json` and `modelOverrides`. See [Model Configuration](docs/models.md#model-configuration). ### Added - Added the opt-in `max` thinking level across CLI, SDK, RPC, model selection, and themes.

See [Model & Thinking](docs/settings.md#model--thinking). - **Project-local resource configuration** - `pi config -l` and Tab switching manage global vs project-local package resources. See [Enable and Disable Resources](docs/packages.md#enable-and-disable-resources). - **Extension lifecycle and provider hooks** - Extensions get `agent_settled`, `before_provider_headers`, entry renderers, and `InlineExtension`. See [agent_start / agent_end / agent_settled](docs/extensions.md#agent_start--agent_end--agent_settled), [before_provider_headers](docs/extensions.md#before_provider_headers), and [InlineExtension](docs/sdk.md#inlineextension). - **New inherited model and transport support** - GPT-5.6 metadata, Copilot Claude Sonnet 5, and zstd Codex SSE transport are available through inherited provider support.

Fixed the edit tool schema to allow model-invented extra replacement fields instead of rejecting otherwise valid edits ([#6278](https://github.com/earendil-works/pi/issues/6278)). - Fixed new session resets to clear cached label timestamps ([#6354](https://github.com/earendil-works/pi/issues/6354)). - Fixed auto-retry for Bun fetch socket-drop errors reported as `socket connection was closed`, so transient provider disconnects do not end headless runs without retrying ([#6431](https://github.com/earendil-works/pi/issues/6431)). - Fixed `models.json` `modelOverrides` to apply to extension-registered provider models ([#6367](https://github.com/earendil-works/pi/issues/6367)). - Fixed project context file discovery to use stable parent traversal on Windows so startup no longer hangs while loading AGENTS.md or CLAUDE.md ([#6369](https://github.com/earendil-works/pi/issues/6369)). -

See [Providers](docs/providers.md) and [Model Options](docs/usage.md#model-options). - **Configurable output spacing** - `outputPad` controls horizontal padding for user messages, assistant messages, and thinking blocks. See [Settings](docs/settings.md#ui--display). - **External editor configuration** - `externalEditor` lets Ctrl+G use a configured editor before `$VISUAL`/`$EDITOR` fallbacks. See [Settings](docs/settings.md#ui--display) and [Keybindings](docs/keybindings.md). - **Richer RPC session tree access** - RPC clients can inspect session entries and tree snapshots with `get_entries` and `get_tree`. See [get_entries](docs/rpc.md#get_entries) and [get_tree](docs/rpc.md#get_tree). - **Extension session metadata updates** - Extensions can observe session name changes through `session_info_changed`.
