Changelog

This page records changes to the Pify documentation site. For Pi releases, use the upstream release history.

2026-09-04

Pify's documentation baseline now follows the official Pi 0.85.0 release and explicitly includes the intervening Pi 0.84.4 release. This is a documentation-release summary of user-visible changes, not a copy of Pi's upstream changelog.

New capabilities

• Documented external session restoration through SessionManager.inMemory() and the ownership boundary for externally stored entries.
• Documented persistent Claude thinking effort: supported Anthropic transports preserve per-turn effort and recover safely from signed-thinking mismatches. supportsMidConvoEffort belongs to AnthropicMessagesCompat, defaults to false, and may be enabled only for an exact supported Claude model on a faithful Anthropic Messages transport; it is the mechanism used for per-turn effort and signed-thinking recovery.
• Added model compatibility fields: vllmPriority belongs to OpenAICompletionsCompat, is relevant to vLLM priority scheduling, and is not set in generated model metadata by default, while vLLM server priority defaults to 0; supportsMaxOutputTokens belongs to OpenAIResponsesCompat, defaults to true, and controls whether Responses-compatible gateways receive max_output_tokens.
• Added relational-algebra LaTeX join-symbol rendering support.
• Added the experimental service architecture formed by @earendil-works/pi-client, @earendil-works/pi-protocol, and @earendil-works/pi-server, including routed sessions, transport, and protocol responsibilities.

Behavior and interface changes

• Added the prompt and RPC lifecycle: ui_prompt_start/ui_prompt_end identify waits for extension UI, while clear_queue returns and removes steering and follow-up messages before abort flows.
• Clarified that built-in path tools resolve the live invocation ctx.cwd, and documented terminal/fullscreen behavior including PI_HYPERLINKS, capability overrides, faster search, selection-copy controls, and the embedded working indicator.
• Recorded the fix for Bash-only Skills.

Reliability/provider fixes

• Covered managed fd/rg downloads on musl without requiring the GitHub Releases API, restored the @earendil-works/pi-coding-agent/client compatibility entry point, and fixed incompatible event sequences and custom Tool-call deltas.
• Codex SSE now processes terminal events without a trailing blank line; fragmented Mistral tool calls retain continuations that omit the tool-call ID; OpenAI reasoning replay merges streamed text and summary deltas; the unavailable Grok model was removed.
• Provider catalog and request fixes make the Qwen catalog include Qwen3.8 Flash, send selected reasoning for Fable, correct Baseten image input metadata, select the Fireworks API adapter, repair Vertex proxy use, include Cloudflare gateway catalog models, and keep OpenRouter models that require reasoning from receiving none effort.
• Recorded JSONL append, concurrent share, collision-safe import, in-memory and file-backed fork, compaction, and manual abort integrity fixes.
• Documented NO_PROXY matching, proxy HTTP tunneling, restricted-seccomp terminal startup, and EXIF orientation scanning; resilient rendering of image-heavy output avoids the V8 string-length-limit crash.

Documentation and verification scope

• Updated the Pify chapters, How-to guides, references, FAQ, Quickstart, examples, and compile fixtures to the 0.85.0 package and source baseline, with focused bilingual structure and behavior verification checks.
• The client/protocol/server service packages remain experimental; this documentation does not present those APIs as stable or promise compatibility beyond the published release.

2026-08-26

• Refreshed the technical baseline and code examples for Pi 0.84.3.
• Added Chapter 11 and three How-to guides for SDK testing, evaluation, and runtime hosting.
• Published an original bilingual course with a separate overview and 15-checkpoint Build Your Own Pi-style Agent path.
• Added an offline TypeScript workshop with focused tests for every checkpoint.
• Expanded the site to 43 synchronized English/Vietnamese pairs and 86 public documents.

2026-08-24

• Added an automated bilingual editorial lint for residual Han characters, control characters, full-width punctuation, mojibake, known literal translations, and long Vietnamese prose without diacritics.
• Defined a canonical English/Vietnamese terminology contract and a review ledger pinned to a specific upstream Pi commit.
• Began the full editorial and technical review of all 23 English/Vietnamese page pairs.

2026-08-22

• Replaced the previous Astro and GitBook delivery experiments with a self-hosted Fumadocs application on Vercel.
• Added English and Vietnamese routing, localized navigation, search, SEO metadata, syntax highlighting, Mermaid rendering, and bilingual end-to-end tests.
• Published the Quickstart, Glossary, Changelog, five task-oriented How-to guides, API/configuration/environment reference pages, and FAQ.
• Added code-block titles and line highlighting through the Fumadocs renderer.
• Fixed localized documentation links so clean routes no longer expose .md filenames.
• Added the Pify logo, adaptive favicon, GPLv3 license, contribution guide, and deployment documentation.

2026-08-20

• Imported the first 10 English and Vietnamese chapters from the Pi Agent Book translation project; the original Chinese Pi Agent Book was the canonical source for that first translation.
• Added the initial documentation navigation and source-provenance records.
• Added a custom 404 page and generated sitemap.
