### New Features - **Clearer Bedrock validation guidance** - Amazon Bedrock data retention validation errors now link to AWS data retention documentation. See [Amazon Bedrock](https://github.com/earendil-works/pi/blob/v0.79.2/packages/coding-agent/docs/providers.md#amazon-bedrock). ### Added - Added an experimental first-time setup flow behind `PI_EXPERIMENTAL=1` that asks for a dark/light theme choice (preselecting the detected appearance) and opt-in analytics data sharing on first launch with the default agent directory; opting in stores a `trackingId` in `settings.json` ([#5587](https://github.com/earendil-works/pi/pull/5587) by [@vegarsti](https://github.com/vegarsti)). - Added AWS data retention documentation links to inherited Amazon Bedrock unsupported data retention mode validation errors ([#5561](https://github.com/earendil-works/pi/pull/5561) by [@unexge](https://github.com/unexge)). ### Fixed - Fixed project trust detection to ignore global `~/.pi/agent` state when running from `$HOME`, and made `pi update` use only saved or explicit project trust without prompting ([#5619](https://github.com/earendil-works/pi/issues/5619)). - Fixed experimental first-time setup to skip forked sessions instead of rerunning the setup prompts ([#5627](https://github.com/earendil-works/pi/pull/5627) by [@vegarsti](https://github.com/vegarsti)). - Fixed inherited OpenAI-compatible context overflow detection for parenthesized `maximum context length (N)` errors ([#5677](https://github.com/earendil-works/pi/issues/5677)). - Fixed inherited OpenAI GPT-5.4/GPT-5.5 and OpenAI Codex GPT-5.4/GPT-5.4 mini/GPT-5.5 context window metadata to match current OpenAI limits ([#5644](https://github.com/earendil-works/pi/issues/5644)). - Fixed inherited Anthropic refusal stops to preserve provider `stop_details` explanations in error messages ([#5666](https://github.com/earendil-works/pi/pull/5666) by [@rwachtler](https://github.com/rwachtler)). - Increased the inherited OpenAI Codex Responses SSE response-header timeout to 20 seconds to reduce false-positive stalls while retaining the bounded wait introduced for zero-event hangs ([#4945](https://github.com/earendil-works/pi/issues/4945)). - Fixed inherited Claude Fable 5 thinking-off requests to omit Anthropic's unsupported `thinking.type: "disabled"` payload ([#5567](https://github.com/earendil-works/pi/pull/5567) by [@tmustier](https://github.com/tmustier)). - Fixed inherited late tool progress callbacks after tool settlement to be ignored instead of emitting stale `tool_execution_update` events ([#5573](https://github.com/earendil-works/pi/issues/5573)). - Fixed inherited user-message transcript rendering so standalone `+` messages no longer render as `-` ([#5657](https://github.com/earendil-works/pi/issues/5657)). - Fixed inherited slash-separated fuzzy queries so provider/model completions remain matchable after insertion. - Fixed inherited WezTerm inline Kitty image rendering so reserved row clears do not erase all but the top strip of tool image previews ([#5618](https://github.com/earendil-works/pi/issues/5618)). - Fixed inherited editor wrapping for CJK text to break at character boundaries instead of leaving large trailing gaps ([#5585](https://github.com/earendil-works/pi/pull/5585) by [@haoqixu](https://github.com/haoqixu)). - Fixed inherited loose Markdown list rendering to preserve blank-line separation between list items ([#5562](https://github.com/earendil-works/pi/pull/5562) by [@Perlence](https://github.com/Perlence)). - Fixed `--model` resolution for authenticated custom model IDs whose slash prefix matches an unauthenticated built-in provider ([#5643](https://github.com/earendil-works/pi/issues/5643)). - Fixed `/fork` to keep session parent chains connected when the forked path contains labels ([#5669](https://github.com/earendil-works/pi/issues/5669)). - Fixed `/share` and `/export` HTML exports to use the active fallback theme when the configured custom theme no longer exists ([#5596](https://github.com/earendil-works/pi/issues/5596)). - Fixed custom fallback model IDs with `:<thinking>` suffixes to preserve the requested thinking level when the provider template model does not advertise reasoning ([#5560](https://github.com/earendil-works/pi/pull/5560) by [@haoqixu](https://github.com/haoqixu)).

### Changed - Updated repository links and package references for the move to `earendil-works/pi-mono` and `@earendil-works/*` package scopes.

### Changed - Changed the Earendil announcement from an automatic startup notice to the hidden `/dementedelves` slash command.

### New Features - Earendil startup announcement with bundled inline image rendering and a linked blog post for April 8 and 9, 2026. - Interactive Anthropic subscription auth warning when Anthropic subscription auth is active, clarifying that Anthropic third-party usage draws from extra usage and is billed per token. ### Fixed - Fixed bare `readline` import to use `node:readline` prefix for Deno compatibility ([#2885](https://github.com/badlogic/pi-mono/issues/2885) by [@milosv-vtool](https://github.com/milosv-vtool)) - Fixed auto-retry to treat stream failures like `request ended without sending any chunks` as transient errors ([#2892](https://github.com/badlogic/pi-mono/issues/2892)) - Fixed interactive startup notices to render after the initial resource listing, and added a bundled Earendil startup announcement with inline image rendering for April 8 and 9, 2026. Moved the blog link above the image to avoid overlap with terminal image rendering. - Fixed interactive mode to warn when Anthropic subscription auth is active, so users know Anthropic third-party usage draws from extra usage and is billed per token.

### Added - Added `gemini-3.1-pro-preview-customtools` model availability for the `google-vertex` provider ([#2610](https://github.com/badlogic/pi-mono/pull/2610) by [@gordonhwc](https://github.com/gordonhwc)) ### Fixed - Documented `tool_call` input mutation as supported extension API behavior, clarified that post-mutation inputs are not re-validated, and added regression coverage for executing mutated tool arguments ([#2611](https://github.com/badlogic/pi-mono/issues/2611)) - Fixed repeated compactions dropping messages that were kept by an earlier compaction by re-summarizing from the previous kept boundary and recalculating `tokensBefore` from the rebuilt session context ([#2608](https://github.com/badlogic/pi-mono/issues/2608)) - Fixed interactive compaction UI updates so `ctx.compact()` rebuilds the chat through unified compaction events, manual compaction no longer duplicates the summary block, and the `trigger-compact` example only fires when context usage crosses its threshold ([#2617](https://github.com/badlogic/pi-mono/issues/2617)) - Fixed interactive compaction completion to append a synthetic compaction summary after rebuilding the chat so the latest compaction remains visible at the bottom - Fixed skill discovery to stop recursing once a directory contains `SKILL.md`, and to ignore root `*.md` files in `.agents/skills` while keeping root markdown skill files supported in `~/.pi/agent/skills`, `.pi/skills`, and package `skills/` directories ([#2603](https://github.com/badlogic/pi-mono/issues/2603)) - Fixed edit tool diff rendering for multi-edit operations with large unchanged gaps so distant edits collapse intermediate context instead of dumping the full unchanged middle block - Fixed edit tool error rendering to avoid repeating the same exact-match failure in both the preview and result blocks - Fixed auto-compaction overflow recovery for Ollama models when the backend returns explicit `prompt too long; exceeded max context length ...` errors instead of silently truncating input ([#2626](https://github.com/badlogic/pi-mono/issues/2626)) - Fixed built-in tool overrides that reuse built-in parameter schemas to still honor custom `renderCall` and `renderResult` renderers in the interactive TUI, restoring the `minimal-mode` example ([#2595](https://github.com/badlogic/pi-mono/issues/2595))

### Fixed - Fixed extension alias fallback resolution to use ESM-aware resolution for `jiti` aliases in global installs ([#1821](https://github.com/badlogic/pi-mono/pull/1821) by [@Perlence](https://github.com/Perlence)) - Fixed markdown blockquote rendering to isolate blockquote styling from default text style, preventing style leakage.

### New Features - Extensions can dynamically remove custom providers via `pi.unregisterProvider(name)`, restoring any built-in models that were overridden, without requiring `/reload` ([docs](https://github.com/badlogic/pi-mono/blob/main/packages/coding-agent/docs/custom-provider.md)). - `pi.registerProvider()` now takes effect immediately when called outside the initial extension load phase (e.g. from a command handler), removing the need for `/reload` after late registrations. ### Added - `pi.unregisterProvider(name)` removes a dynamically registered provider and its models from the registry without requiring `/reload`. Built-in models that were overridden by the provider are restored ([#1669](https://github.com/badlogic/pi-mono/pull/1669) by [@aliou](https://github.com/aliou)). ### Fixed - `pi.registerProvider()` now takes effect immediately when called after the initial extension load phase (e.g. from a command handler). Previously the registration sat in a pending queue that was never flushed until the next `/reload` ([#1669](https://github.com/badlogic/pi-mono/pull/1669) by [@aliou](https://github.com/aliou)). - Fixed duplicate session headers when forking from a point before any assistant message. `createBranchedSession` now defers file creation to `_persist()` when the branched path has no assistant message, matching the `newSession()` contract ([#1672](https://github.com/badlogic/pi-mono/pull/1672) by [@w-winter](https://github.com/w-winter)). - Fixed SIGINT being delivered to pi while the process is suspended (e.g. via `ctrl+z`), which could corrupt terminal state on resume ([#1668](https://github.com/badlogic/pi-mono/pull/1668) by [@aliou](https://github.com/aliou)). - Fixed Z.ai thinking control using wrong parameter name, causing thinking to always be enabled and wasting tokens/latency ([#1674](https://github.com/badlogic/pi-mono/pull/1674) by [@okuyam2y](https://github.com/okuyam2y)) - Fixed `redacted_thinking` blocks being silently dropped during Anthropic streaming, and related issues with interleaved-thinking beta headers and temperature being sent alongside extended thinking ([#1665](https://github.com/badlogic/pi-mono/pull/1665) by [@tctev](https://github.com/tctev)) - Fixed `(external, cli)` user-agent flag causing 401 errors on Anthropic setup-token endpoint ([#1677](https://github.com/badlogic/pi-mono/pull/1677) by [@LazerLance777](https://github.com/LazerLance777)) - Fixed crash when OpenAI-compatible provider returns a chunk with no `choices` array ([#1671](https://github.com/badlogic/pi-mono/issues/1671))
