ChangelogRelease notesSep 4, 2026Pi 0.85.0GitHub releasenpmNew Features

Persistent Claude thinking effort — Supported Anthropic transports preserve per-turn effort and recover safely from signed-thinking mismatches. See Model Configuration. Fullscreen transcript controls — Jump to the latest message from a scrolled transcript and use the embedded working indicator. See TUI Fullscreen Viewport. Restorable in-memory sessions — Resume externally stored session entries through the SDK. See Session Management.

Added

Added SessionManager.inMemory() support for restoring externally managed session entries (#8980 by @y-nk). Added inherited OpenAI-compatible vllmPriority and supportsMaxOutputTokens model settings for vLLM scheduler priority and OpenAI Responses output-token limits (#9004 by @AppleDannyClegg, #8941 by @scturtle). Added inherited LaTeX rendering for relational algebra join symbols (#9050 by @haoqixu). 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 META_API_KEY support.

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).

Fixed managed fd and ripgrep downloads on Linux musl systems (#9070 by @Charlie0113-T). Removed the unavailable inherited Grok Build 0.1 model from /model (#9093 by @Jaaneek). Fixed inherited provider streams emitting incompatible event sequences and custom tool-call deltas. Restored the @earendil-works/pi-coding-agent/client compatibility entry point. Fixed the inherited Qwen Token Plan Individual catalog to include Qwen3.8 Flash (#9021). Fixed inherited OpenAI Codex SSE parsing to process terminal events that are not followed by a blank line (#9047).

Fixed inherited Baseten GLM-5.2 models incorrectly advertising image input support (#8293 by @Panoplos). Fixed skills being unavailable when Bash is the only enabled tool (#8552 by @xl0). Fixed concurrent session shares overwriting one another (#8613 by @wutongyuonce). Fixed image orientation detection skipping EXIF data after non-EXIF APP1 segments (#8616 by @wutongyuonce). Fixed imported sessions overwriting an existing session with the same filename (#8985 by @wutongyuonce). Fixed session forks losing their compaction boundary (#8990 by @acmerfight). Fixed in-memory session forks before an active turn settled (#8937 by @acmerfight). Fixed inherited Fireworks GLM models using the wrong API adapter. Fixed inherited NO_PROXY matching for root domains and subdomains (#8737 by @MeiSiristhebest). Fixed bash, edit, find, grep, ls, read, and write tools ignoring ctx.cwd (#8627 by @vmizg).
