Sourced from @​earendil-works/pi-agent-core's releases.

v0.83.0

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.
• Claude Opus 5 on GitHub Copilot — Use Claude Opus 5 through GitHub Copilot with adaptive thinking and a 1M context window. See 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 (#7243 by @​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).
• Exposed the session's resolved model scope as ctx.scopedModels to extensions. See Extension Context (#7191 by @​pungggi, #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 (#7151 by @​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).
• Added manual redirect URL and authorization-code entry to OpenRouter login for remote and headless environments. See OpenRouter (#7114 by @​rgarcia).
• Added inherited Claude Opus 5 support for GitHub Copilot with adaptive thinking and a 1M context window. See GitHub Copilot (#7158 by @​jay-aye-see-kay).

Changed

• Changed inherited OAuth credential resolution to refresh tokens with less than five minutes of validity remaining instead of waiting until expiration (#7168).

Fixed

• Added a status line when the tool output expansion is toggled (#7180).
• Fixed file-backed SYSTEM.md and APPEND_SYSTEM.md prompts being omitted from the interactive startup context listing. See System Prompt Files (#7096).
• Fixed context files loading twice when a linked Git worktree is nested under its main repository. See Context Files (#7221 by @​arajkumar).
• Fixed llama.cpp streamed responses reporting zero token usage and leaving session context accounting empty. See llama.cpp (#7258 by @​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 (#7022 by @​tmustier).
• Fixed failed Git package installs leaving partial directories that blocked clean retries. See Install and Manage (#7210 by @​haoqixu).
• Fixed the /model selector retaining a stale selection while filtering instead of highlighting the top match (#7211 by @​christianbasch).
• Fixed direct RPC bash commands bypassing extension user_bash handlers. See User Bash Events (#7214).
• Fixed skills, prompts, and themes losing package source metadata after extensions reload resources. See Resource Events (#6968).
• Fixed cancellation of concurrently running user bash commands so every active command is aborted (#7103 by @​yzhg1983).
• Fixed duplicate messages appearing when extensions switch sessions during interactive startup (#7110 by @​yzhg1983).
• Fixed inherited Qwen Token Plan reasoning models to send their service-specific thinking controls and supported reasoning-effort levels (#6951, #6998).
• Fixed inherited Z.AI output limits being sent through an unsupported parameter. See Providers (#7174 by @​HyeokjaeLee).
• Fixed explicitly configured Amazon Bedrock profiles being overridden by ambient AWS access keys. See Amazon Bedrock (#7176 by @​christianbasch).
• Fixed inherited image fallback paths overflowing narrow terminals, shortened home-directory paths, and made absolute paths clickable when terminal hyperlinks are available (#7262).
• Fixed inherited OpenAI-compatible tool calls losing their function arguments when malformed deltas also contain an empty custom object (#7288 by @​sunnyyoung).

v0.82.1

New Features

• Claude Opus 5 — Available on Anthropic and Amazon Bedrock with adaptive thinking (including xhigh), inference profiles, and prompt caching. See Providers.
• 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.
• 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.

[0.83.0] - 2026-07-29

[0.82.1] - 2026-07-25

[0.82.0] - 2026-07-24

Breaking Changes

• Replaced AgentHarness's ExecutionEnv dependency and context-free AgentTool inputs with application-defined toolContext values and context-aware AgentHarnessTool definitions.

Added

• Added context-aware read, write, edit, and bash harness tools backed by ExecutionEnv, including async bash execution preparation.

Changed

• Aligned harness tool path handling, edit serialization, shell output capture, explicit non-inherited environments, and cross-platform process cleanup with coding-agent behavior.

Fixed

• Fixed compaction and branch-summary requests to use fresh routing session IDs with prompt caching disabled where supported (#6618 by @​tmustier).

[0.81.1] - 2026-07-21

Added

• Added retry policy support and lifecycle events for compaction and branch-summary operations in AgentHarness (#6901 by @​davidbrai).

Fixed

• Restored the Agent streamFn option and host-configurable fallback for omitted agent-loop stream functions without reintroducing a pi-ai/compat dependency (#6915).

[0.81.0] - 2026-07-21

Breaking Changes

• Changed SessionStorage to use getPathToRootOrCompaction(), require session name and statistics methods, support cursor-based entry reads, and store retained compaction tails as self-contained checkpoints (#6594 by @​cristinaponcela).
• Moved the uuidv7 export to @earendil-works/pi-ai (#6834 by @​xl0).
• Replaced the optional Agent streamFn fallback with a required streamFunction and made low-level loop stream functions required, preventing @earendil-works/pi-ai/compat and all built-in providers from entering selective-provider bundles (#6851).

Added

• Added usage metadata to tool results, compaction entries, and branch summaries in the agent harness (#6671 by @​davidbrai).

[0.83.0] - 2026-07-29

Breaking Changes

• Upgraded the exported TypeBox dependency 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. Consumers using removed APIs must migrate to supported TypeBox APIs (#7243 by @​petrroll).

Added

• Added per-request fetch injection for supported text and image provider transports; Google adapters reject non-global implementations rather than silently bypassing them.
• Added Claude Opus 5 support for the GitHub Copilot provider, routing through the Anthropic Messages API with adaptive thinking, 1M context, and the Copilot minimal thinking-level override (#7158 by @​jay-aye-see-kay).
• Added the "pending" stop reason for partial streaming messages. See Stop Reasons (#7151 by @​lucasmeijer).
• Added AssistantMessage.rawStopReason and populated it across Google, Anthropic, Amazon Bedrock, Mistral, and OpenAI streams; unmapped terminal reasons now surface as provider errors instead of successful stops (#7272).
• Added manual redirect URL and authorization-code entry to OpenRouter OAuth login for remote and headless environments (#7114 by @​rgarcia).
• Added AuthResolutionOverrides.minOAuthValidityMs so callers can require and refresh OAuth credentials with a minimum remaining validity (#7168).

Changed

• Changed stored OAuth credentials to refresh when less than five minutes of validity remain instead of waiting until expiration (#7168).

Fixed

• Fixed Qwen Token Plan reasoning models to send their service-specific thinking controls and supported reasoning-effort levels (#6951, #6998).
• Fixed Z.AI providers and compatible custom endpoints to send output limits through max_tokens, which those endpoints honor (#7174 by @​HyeokjaeLee).
• Fixed explicitly configured Amazon Bedrock profiles being overridden by ambient AWS access keys (#7176 by @​christianbasch).
• Fixed malformed OpenAI-compatible tool-call deltas with both a valid function payload and an empty custom object discarding the function arguments (#7288 by @​sunnyyoung).

[0.82.1] - 2026-07-25

Added

• Added ModelsStoreEntry.etag so persisted provider catalogs can carry the remote ETag validator for conditional refreshes.
• Added ANTHROPIC_AUTH_TOKEN bearer authentication for Anthropic-compatible gateways (#5871)
• Added Claude Opus 5 support for Anthropic and Amazon Bedrock with adaptive thinking, inference profiles, prompt caching, and preserved AWS validation messages (#7081 by @​unexge, #7083 by @​davidbrai).

Changed

• Changed Radius OAuth device authorization, token exchange, and refresh requests to use the configured gateway directly.
• Changed ModelsError messages to append the underlying cause, so auth failures such as OAuth refresh failed for openai-codex report the provider response instead of a bare wrapper message.

[0.82.0] - 2026-07-24

Breaking Changes

• Replaced getBuiltinModelDataUrl(provider) with getBuiltinModelDataGeneratedAt() so built-in catalog freshness uses its recorded generation time instead of installation-dependent file metadata (#7016 by @​davidbrai).

Added

• Added Kimi Code subscription OAuth login for the kimi-coding provider, with device authorization, token refresh, and OAuth host overrides (#6935 by @​zaycruz).
• Added OpenRouter OAuth PKCE login that mints a user-controlled API key for chat and image providers (#6927 by @​rsaryev).
• Added Tool.constrainedSampling with strict JSON Schema (prefer/require) and OpenAI Lark/regex grammar variants, enforcing provider-side constrained tool sampling across OpenAI, Anthropic, Amazon Bedrock, Google Gemini, and Mistral. See Constrained Sampling for Tools.
