v0.87.02026-09-2124 项记录

以下明细保留官方英文表述，避免翻译改变技术含义。

新功能New Features

Canonical session context and extension boundaries — Edit model context without rewriting history and add actionable lifecycle hooks. See ContextEditEntry and extension events.
Full-transcript context extensions — Use contextwithsystem for per-request system-message transformations. See contextwithsystem.
Per-model image input limits — Configure cache-safe image resizing per model for attachments, read, and tool-result images. See Image Input Limits.

破坏性变更Breaking Changes

Removed the inherited shouldStopAfterTurn agent option. Use finishTurn and return { action: "end" } instead. finishTurn runs before turnend but applies the decision afterward, and it also receives error and aborted responses; migrate normal-response predicates by returning undefined for those hard exits. See the @earendil-works/pi-agent-core changelog for a complete before-and-after example.
Added ContextEditEntry to the exported SessionEntry union. TypeScript consumers with exhaustive entry switches must handle contextedit; use replacement: null for omission and a content replacement otherwise.
Made SessionManager canonical for AgentSession provider context. Assigning session.agent.state.messages no longer replaces future request history; restore with SessionManager.inMemory(cwd, { id }, entries), navigate with session.navigateTree(), or append through session.sessionManager and call session.refreshContext().
Expanded TurnEndEvent with required boundary fields and added AgentBeforeSettleEvent to the exported ExtensionEvent union. Consumers constructing events or exhaustively switching on ExtensionEvent must handle the new shapes. ExtensionRunner.emit() no longer accepts turnend; host integrations dispatch actionable boundaries with emitBoundary(baseEvent, buildContext).
Deferred runs requested from agentsettled handlers until all settled handlers finish. Handlers still observe ctx.isIdle() === true, but no longer see a reentrant agentstart during the same notification dispatch.

新增Added

Added append-only model-context edits. For example, sessionManager.appendContextEdit(entryId, null) omits one message from future provider context without changing raw history, usage, or UI history.
Added actionable turnend and agentbeforesettle extension boundaries. Return { entries: [...event.entries, draft], continue: true } to persist structural entries in order and ensure one next provider request without changing steering or follow-up scheduling.
Added retain-none compaction input: sessionManager.appendCompaction(summary, null, tokensBefore) stores the compaction's own ID as its kept boundary.
Added the contextwithsystem extension event, which runs after context handlers on the full transcript including system messages and sends its result verbatim. See contextwithsystem.
Added per-model image resize profiles through inputLimits.images.resize in models.json, applied to file attachments, image reads, and tool-result images (#9631).

问题修复Fixed

Fixed string context-edit replacements producing invalid assistant and tool-result message content instead of text blocks.
Fixed context-invisible boundary metadata and replacement edits causing newly appended or replaced input to be summarized before its first provider request.
Fixed edited-context accounting both discarding valid assistant usage captured after the latest context edit and reusing that usage after a later compaction made it stale.
Fixed selected error retries and final length/overflow recovery retaining abandoned model attempts in future provider context; post-run recovery omissions are now persisted without hiding raw transcript history or changing queue scheduling.
Fixed context handlers that filter or slice messages dropping the prompt and tool declarations, which after extension-driven compaction left requests without built-in tools or made Codex emit raw tool-call text. Handlers no longer see system messages; Pi restores the prompt and tool state after they run. See context (#9789, #9822).
Fixed /bug allowing uploads in offline mode while preserving local zip exports (#9841 by @christianklotz).
Fixed idle prompt-cache warming rebuilding expired caches when its timer or an extension decision is delayed.
Improved crash diagnostics with hints identifying loaded extensions that appear in the stack trace.
Fixed text files beginning with GIF being misclassified as images and omitted from read and CLI @file input (#9755).
Fixed malformed prompt template frontmatter being silently ignored instead of reported as a resource warning (#9830 by @christianklotz).
Fixed inherited unknown OpenAI-compatible Chat Completions endpoints receiving strict tool schemas unless they explicitly advertise support (#9816).

v0.86.12026-09-208 项记录

以下明细保留官方英文表述，避免翻译改变技术含义。

新功能New Features

Meta Muse provider — Sign in with Meta using /login meta or use METAAPIKEY to access Muse Spark models. See Meta (Muse subscription).

新增Added

Added Meta (Muse subscription) login via /login meta with automatic Model API key refresh, plus METAAPIKEY support (#9096 by @xl0).

行为调整Changed

Enabled Node's persistent compile cache before loading the bundled CLI runtime, reducing repeat launch time.

问题修复Fixed

Fixed /bug descriptions dropping line breaks from pasted diagnostics.
Fixed /bug hints appearing for user cancellations and retryable provider failures such as service unavailability.
Fixed clipboard copy failing in containers and WSL without WSLg by restoring the OSC 52 fallback when no display is available, and added a verified Windows clipboard backend for WSL (#9688).
Fixed inherited z.ai Prompt too long errors not being recognized as context overflow (#9805).
Fixed inherited Cerebras models advertising unsupported strict tool schemas, which caused HTTP 400 errors when strict and non-strict tools were mixed (#9804 by @EdenGottlieb).

v0.86.02026-09-1967 项记录

以下明细保留官方英文表述，避免翻译改变技术含义。

新功能New Features

Prompt cache warming — Keep valuable prompt caches alive during long tool runs and optionally while idle using cost-aware refreshes. See Cache Warming.
Bug reporting — Report problems with /bug using redacted diagnostics, optional transcripts, or exported ZIP archives. See Reporting Bugs.
Transcript-aware prompt and tool updates — Preserve instruction and tool changes across resume and branch navigation while retaining cached prefixes. See beforeagentstart.
Offline Radius model catalog — Select Radius models immediately, with cached and live catalogs overlaid when available. See Radius.
Per-model compaction budgets — Configure reserved and recent-token budgets by model. See Per-model overrides.

破坏性变更Breaking Changes

Changed inherited pi-ai provider stream inputs from Context to normalized TranscriptContext values. Custom providers must read system prompts and tool declarations from context.messages with getCurrentSystemPrompt() and getCurrentTools(). See Custom Streaming API.
Restricted inherited ToolCall.arguments and ToolResultMessage.details to JSON-compatible values, changed ToolResultMessage into a conditional type, and made JsonValue arrays readonly.
userbash now fails closed: errors or invalid defined results abort the command without invoking later handlers or executing locally. Return undefined to continue propagation; otherwise return { operations } or { result } (#9068).

新增Added

Added transcript-backed mid-conversation system prompt and tool changes so instruction and tool updates survive resume and branch navigation while preserving cached prefixes on supported models. See beforeagentstart and Entry Types (#9548).
Added inherited native deferred tool loading for Fireworks Messages models. Use ToolSearch or toolsearch as the loader name for prompt-prefix deferral (#9323).
Added click toggling for branch summaries, compaction summaries, and skill invocation entries.
Added the public Radius model catalog for immediate and offline model selection, with cached and live gateway catalogs overlaid when available.
Added ctx.modelRegistry.stream() and streamSimple() for extension model calls through configured providers with resolved authentication (#8964).
Added per-model reserveTokens and keepRecentTokens settings through compaction.modelOverrides, with ordinary compaction settings as fallback (#8133).
Added compat.allowedFallbackModels configuration for overriding or disabling Anthropic server-side fallback models (#9294).
Added an unsubscribe function from pi.on() so extensions can drop event handlers. Handlers added or removed during a dispatch apply to later dispatches, not the current one (#8967).
Exported extension hook event and result types that were previously omitted from the package entry points (#9642).
Added /bug [description] to report a bug to the Pi developers. The report bundles environment, model, provider, extension, and settings metadata (secrets redacted), assistant message diagnostics from the session, optionally the session transcript, or a model-written summary of what went wrong instead. It is uploaded to Radius (no login required; attributed when logged in) or exported as a zip archive, and the report id is recorded in the session as a pi.bug-report entry. Crashes are recorded in /.pi/agent/crashes.json, announced once on the next start, and attached to the next report; unexplained errors and exhausted retries point at /bug once per session.
Added cost-aware prompt-cache warming during long tool runs and optionally while idle, with configurable modes, model cache-lifetime metadata, /session diagnostics, transcript notices, and the cachewarmingdecision extension event. See Cache Warming (#9668).

行为调整Changed

Enabled Node's persistent compile cache before loading the bundled CLI runtime, reducing repeat launch time.
Made --resume session results appear progressively, using file modification times to prioritize all-folder loading and cancelling outstanding transcript reads after selection.
Reduced --continue startup time by checking candidate session headers in modification-time order and stopping after the newest matching session.
Replaced the external native clipboard dependency with bundled asynchronous macOS, Windows, and X11 helpers while preserving platform command and OSC 52 fallbacks (#9163).
Reduced inherited fuzzy search latency for long texts by using native substring search instead of scanning each character in JavaScript (#9267).
Moved compaction, branch summarization, and retry spinners into the editor border alongside the working indicator. Custom editors use the same embedding opt-in for all status spinners.
Enabled strict-prefer JSON-schema sampling by default for built-in read, bash, powershell, edit, and write tools, without requiring PIEXPERIMENTAL. Extensions can re-register tool definitions with constrainedSampling: false.
Formatted Bash and PowerShell tool durations of at least one minute as minutes and seconds, with hours when needed (#9628).
Deferred the extension compiler and bundled virtual modules until a filesystem extension is loaded, reducing the baseline SDK import cost (#9540).

问题修复Fixed

Fixed GitHub Copilot GPT models, including GPT-6 Astra, using the Chat Completions adapter instead of the required Responses adapter (#9253 by @petrroll).
Fixed inherited DeepSeek V4.1 thinking levels on OpenRouter and OpenCode Go preserving provider effort metadata (#9485).
Fixed inherited bodyless HTTP 400/413 errors from non-Cerebras providers being misclassified as context overflow (#9482).
Fixed inherited Vercel AI Gateway replaying unsigned thinking as assistant text (#9676).
Fixed inherited Google Generative AI and Vertex AI using unsupported thinking levels when reasoning is omitted or when model capabilities differ within a Gemini family (#9455).
Fixed inherited Anthropic-compatible relays breaking signed thinking replay when they report a different response model, while preserving fallback pricing (#9188).
Fixed inherited Amazon Bedrock one-hour cache writes being priced at the five-minute rate (#9457).
Fixed inherited quadratic CPU usage when draining buffered EventStream events (#9055).
Fixed inherited Mistral Medium reasoning requests to use reasoningeffort for all reasoning-capable mistral-medium- model IDs instead of the unsupported promptmode (#8700).
Fixed inherited OpenCode and OpenCode Go requests to send x-opencode-session from sessionId across all supported API adapters (#9326).
Fixed inherited OpenAI Codex requests to send the model's Off reasoning effort instead of omitting it, while respecting unsupported Off mappings (#9191).
Fixed inherited Fireworks unsigned thinking replay and reasoning effort selection using catalog metadata, with verified DeepSeek V4 and Qwen3.8 fallbacks and removal of redundant GLM 5.2 and Kimi K3 effort aliases (#9323).
Fixed inherited OpenRouter requests to send x-session-id from sessionId for Chat Completions and Anthropic Messages models when prompt caching is enabled (#9102).
Fixed the inherited DeepSeek catalog to advertise deepseek-flash for DeepSeek V4.1 Flash instead of retired Flash aliases, and refreshed DeepSeek pricing metadata (#9423).
Fixed inherited Mistral-hosted GLM-5.2 reasoning requests to use reasoningeffort instead of the ignored promptmode (#9375).
Fixed inherited OpenAI-compatible Responses errors to identify the actual provider instead of always labeling them as OpenAI errors (#9298).
Fixed inherited Baseten requests to send session-affinity headers from sessionId for automatic prompt-cache routing (#9629).
Fixed inherited retry classification for Cloudflare 520 responses (#9627).
Fixed inherited retry classification for transient Azure peak-load capacity errors (#9669).
Fixed session tree navigation racing with active compaction and replacing its progress UI (#9179 by @acmerfight).
Fixed exact session ID lookup scanning complete transcript bodies instead of reading session headers (#9601 by @metaist).
Fixed repeated Anthropic thinking-drop notices being shown for the same dropped blocks, and shortened notices while retaining details in the session (#9391).
Fixed mid-run threshold compaction silently skipping oversized trailing tool results (#9740).
Fixed signal-terminated local shell commands being reported as successful with partial output (#9577 by @BrendanJMurphy).
Fixed local clipboard failures reporting success when the terminal ignored the fallback OSC 52 write, and added platform-specific setup guidance when no clipboard backend works (#9618).
Capped agent-level retry backoff at retry.maxAgentDelayMs (60s by default) so long retry runs stay responsive during prolonged transient outages (#8826).
Fixed direct RPC steer and followup commands bypassing extension input handlers (#8718).
Fixed premature missing-model errors after login by waiting for catalog discovery. Radius now defaults to balanced, falling back to the first available Radius model when needed.
Fixed fullscreen mode reserving a blank row for custom footers that render zero rows (#8919).
Fixed extension tools without parameter schemas to be rejected during registration instead of breaking provider requests (#9300).
Fixed beforeagentstart handlers returning systemPrompt (and forceSystemPrompt) on models with mid-conversation system messages: the forced prompt is now sent as the provider's leading system prompt instead of being appended as a section patch after the original prompt.
Fixed loaded llama.cpp models with enablethinking chat templates ignoring Pi's thinking level (#9528).
Fixed cancellation races that could start automatic compaction, leave stale retry state, or miss cancellation while waiting for summarization authentication (#9340, #9777).
Fixed asynchronous Kitty image conversion replacing newer partial tool output images (#8743 by @wutongyuonce).
Fixed inherited skill slash-command autocomplete ranking the skill: prefix instead of the bare skill name (#9120 by @yearth).
Fixed inherited file autocomplete boundaries and path quoting around CJK punctuation (#9746 by @haoqixu).
Fixed inherited LaTeX legacy font switches falling back to raw source, centered cases layouts around surrounding equations, and vertically laid out unsupported and nested display scripts (#8827, #9564, #7929).
Fixed inherited fullscreen Kitty images being erased by later row clears in WezTerm (#9169).

移除Removed

Removed unavailable inherited GPT-5.4 and GPT-5.4 mini models from OpenAI Codex selection (#9394).

Added five-times-faster mouse wheel scrolling while holding Alt in fullscreen mode (#9166 by @xl0).

问题修复Fixed

Fixed configurable save keybindings in the model and thinking selectors (#9149 by @rwachtler).
Fixed SDK import failures caused by unintentionally publishing internal experimental code and dependencies in 0.85.0. The experimental client and experimental/plugin subpaths and server/client commands are now source-only through pi-test.sh; the supported local SDK and stdio RPC API are unchanged (#9132).
Fixed mouse hover changing selection and recentering autocomplete and settings lists, causing clicks to target a different item.
Fixed long prompt-cache requests for GPT-5.6+ Responses models to use promptcacheoptions.ttl: "30m" instead of promptcacheretention: "24h".

Added a clickable "Jump to latest message" label with the tui.altScreen.bottom shortcut to the fullscreen transcript while it is scrolled up (#9080 by @rwachtler).
Added Meta (Muse subscription) login via /login meta with automatic Model API key refresh, plus METAAPIKEY support.

行为调整Changed

Moved the streaming working indicator into the default editor border and matched its default spinner and label to the thinking-level border color. Custom editors retain the standalone indicator unless they opt in to embedding it (#8799 by @cristinaponcela).
Reduced inherited fullscreen transcript search latency on large transcripts by caching unchanged search results, indexing ASCII runs, and limiting highlight work to visible matches (#8800 by @cristinaponcela).

v0.84.42026-08-2834 项记录

以下明细保留官方英文表述，避免翻译改变技术含义。

新功能New Features

Terminal capability overrides — Override detected terminal hyperlink, image, and truecolor support. See Capability Overrides.
Extension UI prompt events — Integrations can distinguish active agent work from time spent waiting for ctx.ui prompts. See Extension UI prompt events.
RPC queue clearing — Retrieve and clear queued steering and follow-up messages with clearqueue. See RPC clearqueue.
Fullscreen selection copy controls — Disable automatic selection copying in fullscreen mode and use Ctrl+X to copy the active selection. See UI & Display.
DeepSeek V4 Flash Vision (experimental) — Use the vision-capable model through the built-in DeepSeek provider. See API Keys.

新增Added

Added supportsMidConvoEffort to custom Anthropic Messages model compatibility settings.
Added transcript notices for Anthropic thinking blocks dropped during provider recovery when cache miss notices are enabled.
Added uipromptstart and uipromptend extension events so host integrations can distinguish active agent work from waiting on user-facing ctx.ui prompts (#8355 by @cristinaponcela).
Added detectSupportedImageMimeTypeFromFile() to the public library exports (#8600 by @xl0).
Added inherited experimental vision-capable deepseek-v4-flash-vision-exp model support.
Added transcript usage notices for compaction and branch summaries when cache miss notices are enabled.
Added RPC clearqueue to retrieve and remove queued steering and follow-up messages (#8432).
Added environment variables and advanced settings for overriding auto-detected terminal hyperlink, image, and truecolor capabilities (#8665).
Added fullscreenCopyOnSelect to disable automatic fullscreen selection copy; when disabled, Ctrl+X copies the active text selection before falling back to the last assistant message, while /tree still copies the selected message (#7720).

行为调整Changed

Changed fullscreen scrollbars to reveal on pointer entry, support optional scrollbarTrack and scrollbarThumb theme colors with muted and text fallbacks, keep one thumb color across normal and expanded states, and support track-click jumping.
Changed fullscreen transcript search arrows to underline on hover and capitalized the search placeholder.
Changed selectors in /thinking, /model, /scoped-models, /trust, per-model thinking settings, and theme settings to keep active options marked while browsing. /scoped-models now uses consistent per-item toggles and strikes through unavailable models (#8900).

问题修复Fixed

Fixed toggling thinking visibility clearing partial output from running Bash tools (#8611).
Fixed Windows shell aborts crashing Pi when taskkill.exe is unavailable on PATH (#6596).
Fixed resumed sessions corrupting the next appended entry when their JSONL file lacks a trailing newline (#8345).
Fixed extension messages sent with triggerTurn: false while the agent is running being inserted between a tool call and its result, which made providers that validate message order reject the replayed history. They are now appended once the turn's tool results are in (#8537).
Fixed compaction and branch summaries forcing toolChoice: "none" (#8649, #8638).
Fixed large tool results crossing the auto-compaction threshold being sent to the provider before compaction. Pi now compacts between tool execution and the next assistant response in the same run, and restores interactive progress when that run resumes (#6879).
Fixed Google Vertex requests failing with HttpsProxyAgent is not a constructor when the bundled Node.js runtime uses an HTTP(S) proxy (#8610).
Fixed saving a default model from a non-empty model scope so it remains available in that scope.
Fixed inherited @ file autocomplete ranking to prefer direct and shallower matches over similarly ranked nested paths (#8669).
Fixed inherited OpenAI-compatible streams serializing thinking signatures repeatedly during streaming (#8671).

Fixed inherited fullscreen double-click word selection splitting paths and kebab-case tokens on / and - (#8676).
Fixed inherited Cloudflare AI Gateway catalogs omitting supported workers-ai/ passthrough models.
Fixed inherited OpenAI-compatible reasoning replay to merge consecutive streamed text and summary reasoningdetails deltas.
Fixed inherited OpenRouter reasoning controls so reasoning-mandatory models do not receive effort: "none" (#8614 by @davidbrai).
Fixed inherited OpenAI-compatible Chat Completions ignoring an explicitly requested toolChoice when no tools are defined.
Fixed inherited fragmented Mistral tool calls splitting when continuation chunks omit the tool-call ID (#8387).

v0.84.32026-08-2464 项记录

以下明细保留官方英文表述，避免翻译改变技术含义。

新功能New Features

PowerShell tool — Use optional native PowerShell command execution on Windows. See PowerShell Tool.
Safer managed updates — Stage, verify, and atomically activate updates for installer-managed installations. See Install and Manage.
Model and thinking controls — Select thinking levels with /thinking, search defaults, keep selections session-scoped, and persist them explicitly with Ctrl+S. See Models and Thinking.

破坏性变更Breaking Changes

新增Added

Added an optional powershell tool for Windows, configurable through defaultTools and the SDK. See PowerShell Tool.
Added a /thinking selector and searchable default choices to the model and thinking selectors; Ctrl+S saves the selected model as the global default. See Models and Thinking.
Added optional routing session IDs to exported compaction summary helpers so callers can preserve provider routing without enabling prompt cache writes.
Added transcript usage notices for compaction and branch summaries when cache miss notices are enabled.
Added sessioncompactfailed extension events so compaction failures and aborts expose their reason, retry state, source, and error message to handlers (#8175).
Added inherited provider-neutral toolChoice support to simple stream requests.
Added inherited automatic Anthropic server-side refusal fallback for supported first-party models, including returned-model usage pricing (#8017).
Added inherited configurable OpenAI-compatible thinking-token budget fields for vLLM, Qwen/SGLang, and llama.cpp servers. See OpenAI Compatibility (#8275 by @bnsd55).
Added inherited China-specific ZAI Coding Plan models, including GLM-4.6V vision support and API-equivalent usage cost estimates (#8220).
Added inherited deepseek-v4-pro-0813 support to the Qwen Token Plan Individual catalog (#8194).

行为调整Changed

Changed experimental installer-managed installations so pi update stages, verifies, and atomically activates the selected release in place. See Install and Manage.
Changed inherited built-in xAI models to use the Responses API with encrypted reasoning replay and made Grok 4.6 the default xAI model (#8124 by @Jaaneek).
Changed inherited Anthropic, Azure OpenAI, Google, Mistral, and OpenAI adapters to send Pi's default User-Agent unless overridden (#8305).
Changed Windows and WSL keybinding defaults to avoid terminal-reserved shortcuts for image paste, model cycling, editor undo, fullscreen transcript navigation and search, and message queueing (#8372).
Changed Bun release archives to ship the native clipboard binary only inside the wrapper package, removing a duplicate platform package from each archive.
Changed package resource glob expansion to use Node.js's built-in implementation with deterministic visible-path matching, reducing the installed runtime dependency tree.
Changed the bundled Node.js runtime to load jiti only when importing an extension and Babel only when uncached source needs transformation, reducing CLI startup time and bundle size.
Changed syntax highlighting to initialize only twenty common languages eagerly and defer the remaining grammars until after the initial TUI render, reducing CLI startup time.
Changed the Node.js CLI and RPC entrypoints to load a bundled runtime, reducing startup filesystem reads while keeping the public library and legacy module paths on the modular runtime for normal dependency identity.
Changed session sharing to render clickable terminal links, display only the canonical Radius artifact URL, and include the current system prompt and active tool definitions in Radius session shares.

问题修复Fixed

新功能New Features

Qwen Token Plan Individual — Use the built-in provider for models documented for Individual subscriptions. See API Keys.
Authentication readiness checks — Use pi auth check to verify provider or model credentials, optionally emitting the resolved credential.
Improved fullscreen interaction — Select words and paragraphs with multiple clicks and configure half-page transcript scrolling. See TUI Fullscreen Viewport.
Terminating blocked tool calls — Extension toolcall handlers can stop all-terminating batches without another model call. See Tool Events.

新增Added

Added Qwen Token Plan Individual as a built-in provider with its documented subscription model catalog and the shared international QWENTOKENPLANAPIKEY. See API Keys (#7659 by @arasovic).
Added pi auth check provider/model auth preflight with optional credential output (#7152).
Added terminate support to blocked extension toolcall events so all-terminating batches can skip the automatic follow-up model call. See Tool Events (#7715 by @muyiyr).
Added inherited double-click word and whitespace selection, granularity-aware drag selection, and triple-click paragraph selection in fullscreen mode (#7725, #7733 by @volsa).

新功能New Features

Fullscreen TUI mode — Switch between regular and fullscreen modes at runtime, with a sticky editor and footer, independently scrollable transcript, and draggable scrollbars. See UI & Display.

Baseten provider — Use built-in Baseten authentication and model support. See API Keys.

破坏性变更Breaking Changes

Renamed the inherited pi-ai ModelsStreamTransforms interface to ModelsRequestTransforms because its header transformation now applies to all authenticated provider requests.
Changed JSON and RPC messageupdate events to emit only assistantMessageEvent deltas, removing the cumulative message and assistantMessageEvent.partial fields that caused quadratic output growth. Clients that need partial messages must assemble deltas between messagestart and messageend; the latter remains authoritative (#7290).
ModelRegistry.getApiKeyAndHeaders() now returns ProviderHeaders with string | null values and preserves null header-deletion markers. Extensions that inspect returned headers must handle null; extensions forwarding them to pi-ai streams should pass them through unchanged. This prevents placeholder OpenAI credentials from being sent through Cloudflare AI Gateway (#7030).
Changed ModelRegistry.refresh() to accept ModelsRefreshOptions and return ModelsRefreshResult instead of discarding cancellation and provider errors.
Changed ModelRuntime.setRuntimeApiKey() to accept auth cancellation options rather than catalog refresh options. Call refresh({ providers: [providerId], signal }) separately when remote freshness is required.
Required config-form extension OAuth refreshToken(credentials, signal) callbacks to accept and honor a concrete abort signal.
Replaced dynamic provider refresh context store access with the read-only context.stored snapshot and generation-checked context.publish() transaction.
Providers built with createProvider({ fetchModels }): no catalog-publication migration is required. Before and after, return the fetched models and register the resulting provider; createProvider() owns restoration, persistence, and in-memory publication.
// Before · const beforeProvider = createProvider({ · // ... · fetchModels: async ({ signal }) => { · const response = await fetch(catalogUrl, { signal }); · return parseModels(await response.json()); · }, · }); · pi.registerProvider(beforeProvider); · // After: unchanged · const afterProvider = createProvider({ · // ... · fetchModels: async ({ signal }) => { · const response = await fetch(catalogUrl, { signal }); · return parseModels(await response.json()); · }, · }); · pi.registerProvider(afterProvider);
Handwritten native Provider.refreshModels(): replace direct store access and pre-publication mutation with generation-guarded publications.
// Before · refreshModels: async (context) => { · const stored = await context.store.read(); · if (stored) currentModels = stored.models; · if (!context.allowNetwork) return; · const refreshed = await fetchModels(context.signal); · currentModels = refreshed; · await context.store.write({ models: refreshed, checkedAt: Date.now() }); · }, · // After · refreshModels: async (context) => { · if (context.stored) { · const restored = context.stored.models; · if (!(await context.publish({ · update: () => { currentModels = restored; }, · }))) return; · } · if (!context.allowNetwork) return; · const refreshed = await fetchModels(context.signal); · if (context.signal.aborted) return; · await context.publish({ · persist: { models: refreshed, checkedAt: Date.now() }, · update: () => { currentModels = refreshed; }, · }); · },
For the config-form pi.registerProvider(name, { refreshModels }), callbacks that only return models remain unchanged; pi publishes the returned list. If such a callback previously used context.store for custom persistence, read context.stored and call context.publish({ persist: entry }). In publish(), omit persist to leave storage unchanged, pass a ModelsStoreEntry to write it, or pass persist: null to delete it.
Replaced the inherited pi-agent-core harness session model with the v4 lane-based Session, SessionStorage, and SessionRepo APIs, including durable operation records, global facts, shared sequence numbers, and tree-scoped lane views.
Promoted the inherited v2 session and AgentHarness API from pi-agent-core's experimental entrypoint to its default export and removed the experimental subpaths.
Removed the inherited legacy JSONL and in-memory repository APIs. Use pi-agent-core's v4 JsonlSessionRepo or InMemorySessionRepo, both implementing the new SessionRepo contract.
Added the inherited required pi-agent-core FileSystem.renameFile() operation for atomic JSONL publication; custom harness file-system implementations must provide same-filesystem replacement semantics (#7707 by @davidbrai).
Replaced experimental remote-session list summaries with durable SessionMetadata; RemoteSession.sessions no longer exposes runtime phase, model, thinking, attachment, or lock state, which remains available from acquired SessionSnapshot values (#7708).

新增Added

Added built-in Baseten provider support with BASETENAPIKEY authentication and zai-org/GLM-5.2 as the default model.
Added experimental remote-session client APIs: the transport-neutral PiClient, CBOR protocol, Unix-socket transport, and @earendil-works/pi-coding-agent/client RemoteSession controller with transcript reducers. See Pi Client and Remote Protocol (#7344, #7348, #7371, #7409).
Added CredentialSynchronizationError for credential changes that commit successfully but fail to synchronize local model state.
Added chainable pi.registerMarkdownTransformer() hooks for display-only transformation of user and assistant Markdown. See pi.registerMarkdownTransformer() (#7231 by @xl0).
Added an experimental fullscreen TUI mode, selectable through --tui-mode fullscreen or /settings (#7304).
Added runtime switching between regular and fullscreen TUI modes through /settings.
Added a sticky editor, status, widget, and footer dock to fullscreen mode while keeping the transcript independently scrollable.
Added a draggable transcript scrollbar to fullscreen mode with configurable auto, always, and hidden modes through /settings; always reserves the rightmost column.
Added page scrolling and marked-message navigation shortcuts to fullscreen mode.
Added an optional scrollbarThumb theme color for fullscreen scrollbar thumbs, falling back to selectedBg.
Added configurable themed Unicode rendering for supported Mermaid diagrams in interactive messages, including optional rendering while streaming. See Markdown settings (#7624 by @xl0).
Added opt-in Ctrl+P/Ctrl+N prompt history navigation, with explicit history bindings taking precedence over application shortcuts while the editor is focused.
Added per-directory AGENTS.override.md context files, which replace AGENTS.md or CLAUDE.md in the same directory while preserving context from other directories. See Context Files (#7681 by @Marvae).
Added AIAGENT=pi to CLI and RPC child-process environments for generic agent attribution. See Environment Variables (#7493 by @renaudhartert-db).
Added inherited terminal-friendly Unicode rendering for LaTeX expressions in Markdown. See TUI Markdown.
Added stacked transient notifications in fullscreen mode.
Added arbitrary OpenAI-compatible model sampling parameters through samplingParams in models.json, model overrides, extension providers, and stream options. See Sampling Parameters (#7568 by @mrexodia).
Added inherited opt-in vLLM thinkingtokenbudget support for OpenAI-compatible models, reserving output tokens for the final answer (#7638 by @bnsd55).
Added inherited support for OpenAI-compatible streams that omit finishreason, using compat.supportsFinishReason to infer normal and tool-use stops when the stream ends. See OpenAI Compatibility.
Added inherited deferred provider request contracts, durable response handles, authenticated fetch/cancel dispatch, and faux-provider support for pending, ready, failed, and cancelled responses (#7339 by @davidbrai).
Added inherited vendor-neutral telemetry contracts plus agent-owned typed AI-request and harness schemas, composed span starters, and callback helpers. See the agent telemetry schema reference.
Added inherited structured Amazon Bedrock failure diagnostics with HTTP status, modeled error code, and AWS request id when available (#7286 by @brianstanley).
Added inherited AgentOptions.shouldStopAfterTurn for gracefully stopping after a completed turn before queued messages or another model call are processed. See Agent Options (#7367 by @acmerfight).
Added inherited v4 JsonlSessionRepo support for append-only JSONL harness sessions (#7611 by @davidbrai).
Added inherited bounded branch-entry and indexed open-operation recovery queries to the v4 session API (#7448, #7646).
Added the inherited compile-complete AgentHarness v2 scaffold; unfinished operation paths reject with HarnessNotImplemented while durable execution is implemented.

行为调整Changed

Added inherited optional cancellation to pi-ai ModelsStore reads, writes, and deletions; catalog orchestration binds these waits to the provider refresh signal.
Reduced the inherited default fullscreen mouse wheel step from three lines to one for finer scrolling.

问题修复Fixed

Fixed inherited OAuth token refreshes so stalled requests release the credential-store lock (#7508).
Fixed inherited tool argument validation to preserve values that already match an anyOf/oneOf union arm before coercion, avoiding nullable unions converting null to another primitive value (#7328).
Fixed inherited Fireworks GLM 5.2 requests sending the unsupported promptcacheretention field when long cache retention is enabled, and enabled session affinity for automatic prompt caching (#7676).

Fixed inherited GitHub Copilot Grok 4.5 requests to use the supported Responses API (#7560).
Fixed fullscreen shutdown leaking terminal capability-query replies into the parent shell prompt.
Fixed bare exact --model IDs shared by multiple providers choosing the first catalog entry instead of the sole authenticated provider or a clear ambiguity error (#7327).
Fixed standalone x64 binaries requiring Haswell-era AVX2/BMI2 instructions by compiling release executables against Bun's baseline runtime (#7390 by @davidbrai).
Fixed Ctrl+X copy confirmations in fullscreen mode adding a transcript status line instead of showing the transient Copied! marker.
Fixed Kitty image previews in fullscreen mode overlapping the sticky editor and footer dock while scrolling.
Fixed image-heavy fullscreen sessions lagging when layout changes retransmitted visible Kitty image payloads and rendered the transcript twice per frame.
Fixed spaces in /settings searches toggling the highlighted setting while typing multi-word queries such as TUI mode or Quiet startup.

Fixed long-running sessions using stale credentials after another process updates auth.json without serializing concurrent credential reads and delaying startup (#7319).
Fixed concurrent models-store.json reads forming a file-lock convoy and delaying startup.
Updated the packaged brace-expansion dependency to 5.0.8 to address GHSA-mh99-v99m-4gvg (#7316).
Fixed forced model availability refreshes remaining blocked behind a stalled earlier refresh (#7301, #7421 by @a-yeyang).
Fixed /model catalog refresh failures to identify every catalog that failed.
Fixed provider login remaining stuck after saving credentials when a model catalog refresh stalls by separating local credential consistency from bounded background freshness (#7027, #7113, #7418).
Fixed /scoped-models waiting for remote catalogs before rendering instead of showing cached models and cancelling refresh on close (#7153).
Fixed /model name waiting for catalog refresh before checking cached model matches (#7443).
Fixed stale availability snapshots and errors publishing after a newer availability pass.
Fixed stale pi.dev, Radius, llama.cpp, and extension catalog refreshes publishing after a newer provider refresh.
Fixed cancellation while waiting for file-backed credential or model-catalog locks, preventing cancelled mutations from running or committing later.
Fixed concurrent in-memory credential mutations losing unrelated provider updates by serializing their read-modify-write sections.
Updated undici to 8.9.0 and the packaged brace-expansion to 5.0.9 to address GHSA-8xcm-r25x-g524, GHSA-4cwx-7wf7-3272, GHSA-m8rv-5g2x-5cg5, GHSA-jr45-8vmc-qm54, GHSA-v3r7-h72x-cjcm, and GHSA-rgw5-rvv9-x895.

Anthropic gateway bearer auth — ANTHROPICAUTHTOKEN authenticates against Anthropic-compatible gateways that require Authorization: Bearer, including compaction and branch summaries. See 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.

新增Added

Exposed the outputPad setting to custom message renderers. See Extensions (#7045 by @xl0).
Added inherited ANTHROPICAUTHTOKEN bearer authentication for Anthropic-compatible gateways. See Providers (#5871).
