# Changelog

All notable changes to GNO will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [1.5.2] - 2026-05-25

### Fixed

- Hardened local model backend startup on Windows by making `node-llama-cpp`
  source builds opt-in, timing out backend initialization, retrying CPU when
  automatic backend selection fails, and capping CPU embedding contexts on
  low-memory Windows machines.

## [1.5.1] - 2026-05-09

### Fixed

- Restored `gno mcp serve --help` so the explicit MCP server subcommand shows normal help output without affecting stdio server startup.

## [1.5.0] - 2026-05-09

### Added

- Added graph-aware hybrid retrieval, graph edge confidence/audit metadata, graph health reports, CLI graph traversal, MCP graph neighbor/path tools, and Web UI community filtering.

## [1.4.2] - 2026-04-26

### Changed

- Updated `minimatch` from 10.1.1 to 10.2.3 and regenerated `bun.lock` so frozen installs stay reproducible.

## [1.4.1] - 2026-04-24

### Added

- Added `gno bench <fixture>` for local retrieval benchmark fixtures, including terminal and JSON output, fixture/result schemas, BM25/vector/hybrid mode comparisons, IR metrics, and an example fixture.

## [1.4.0] - 2026-04-24

### Added

- Added an experimental AST chunking benchmark harness that compares real tree-sitter chunk boundaries against GNO's heuristic code chunker without changing production chunking behavior.

### Changed

- Upgraded `node-llama-cpp` to 3.18.1 and `sqlite-vec` to 0.1.9 after upstream release checks and local smoke validation.
- Pinned direct dependencies and devDependencies to exact versions, keeping only compatibility peer ranges.
- Improved MCP tool descriptions and docs so agents better use `intent`, `queryModes`, line-range `gno_get`, and batched `gno_multi_get` workflows.
- Documented that the tree-sitter AST chunking benchmark did not improve retrieval score on the canonical code fixture, so production indexing keeps the heuristic chunker.

## [1.3.1] - 2026-04-24

### Fixed

- Fixed Windows path handling for named-index status output and publish export Downloads directory resolution.

## [1.3.0] - 2026-04-24

### Added

- Added `line` to structured search result JSON and indexed URI output metadata (`?index=<name>`) for non-default indexes.
- Added explicit local llama backend selection with `GNO_LLAMA_GPU` plus GGUF cache validation for downloaded/local model files.

### Fixed

- Fixed `gno status`, `update`, `index`, `embed`, and retrieval/search readers to honor named indexes consistently.
- Hardened sqlite-vec diagnostics, oversized embedding inputs, and pathological one-line chunking.

## [1.2.1] - 2026-04-22

### Fixed

- Fixed several retrieval and publish-export hot paths to batch content/tag loading instead of issuing repeated per-document reads for `--full` search results and collection publish exports.
- Fixed model-cache manifest metadata to persist SHA-256 checksums for downloaded model files instead of leaving checksum fields empty.
- Fixed model-cache lock recovery so recent lockfiles from the same host are reclaimed when the recorded owner PID is no longer alive, reducing false lock contention after crashed downloads.

## [1.2.0] - 2026-04-22

### Added

- Added `--detach` to `gno serve` and `gno daemon` to self-spawn a detached background child (macOS/Linux); parent prints `{pid, url}` (serve) or `{pid}` (daemon) and exits 0.
- Added `--status` to `gno serve` and `gno daemon` to inspect the recorded pid-file with liveness check; pair with `--json` for the [`process-status` schema](spec/output-schemas/process-status.schema.json) on stdout.
- Added `--stop` to `gno serve` and `gno daemon` for graceful SIGTERM (10s timeout) with SIGKILL fallback; silent when nothing is running (rely on exit code 3, not stderr).
- Added `--pid-file <path>` and `--log-file <path>` to `gno serve` and `gno daemon` to override the default `{data}/{kind}.{pid,log}` locations.
- Added `NOT_RUNNING` exit code (`3`) emitted by `--status` and `--stop` when no live matching process is found. `--status` still emits the schema-shaped payload on stdout in JSON mode; `--stop` is silent and scripts should branch on the exit code.

### Changed

- `--json` is now restricted to `--status` on both `gno serve` and `gno daemon`. Combining `--json` with `--detach`, `--stop`, or the foreground path raises a `VALIDATION` error (exit 1) so callers can't silently expect structured output.
- Documented the live-foreign case (operator upgraded gno while a detached process from an older binary is still running). `--stop` refuses to signal foreign-version pids; `--status --json` surfaces `details.foreign_live = { pid, recorded_version, current_version }` on the NOT_RUNNING envelope.

## [1.1.0] - 2026-04-21

### Fixed

- Fixed `gno collection clear-embeddings` to bootstrap the data directory before opening SQLite, which removes the Windows-only `unable to open database file` failure seen in CI and in fresh local environments.
- Fixed publish export default output path resolution across platforms. `gno publish export` now resolves the user's Downloads directory more carefully: `USERPROFILE` on Windows, `XDG_DOWNLOAD_DIR` or `user-dirs.dirs` on Linux, and `~/Downloads` fallback on macOS/Linux when no override exists.
- Fixed Windows-brittle benchmark and publish tests by removing hardcoded POSIX paths and raw `"bun"` executable assumptions.

## [1.0.5] - 2026-04-21

### Changed

- Updated key dependencies on the 1.0.x line, including `evalite`, `lucide-react`, `shiki`, and `softprops/action-gh-release`.
- Thanks [@dependabot](https://github.com/dependabot) for the upgrade PRs.

## [1.0.4] - 2026-04-20

### Changed

- Updated the bundled agent skill at `assets/skill/` to document the 1.0.2/1.0.3 publish features: `--passphrase` for encrypted shares, `--preview` for the sanitizer dry-run, and the Obsidian pre-processor (wikilink conversion, `_internal/` stripping, nav-sidebar drop, `![[image]]` warning, `publish: false` frontmatter refusal). Agents installed via `gno skill install` now teach the model the current publish surface.
- Added `assets/skill/README.md` to the skill package so the ClawHub listing (https://clawhub.ai/gmickel/gno) documents both install paths: the native `gno skill install --target {claude,codex,opencode,openclaw,all}` and `openclaw skills install gno` from ClawHub.

## [1.0.3] - 2026-04-20

Re-release of 1.0.2 with a CHANGELOG formatting fix so the Publish workflow's
`lint:check` step passes on CI. No code or behavior change from 1.0.2; the
1.0.2 tag never produced an npm release.

## [1.0.2] - 2026-04-20

### Fixed

- Fixed `gno publish export` leaking raw Obsidian syntax into published artifacts. Wikilinks (`[[Note]]`, `[[Note|alias]]`), image embeds (`![[image.png]]`), `_internal/` private-path references, and Obsidian nav-sidebar lines are now sanitized out of the artifact before it is uploaded to `gno.sh`.
- Fixed `gno publish export` honoring a `publish: false` frontmatter field so notes flagged as non-publishable are refused (for single-note exports) or silently skipped (for collection exports), matching Obsidian's own publish convention.

### Added

- Added `gno publish export --preview` which prints the sanitized markdown plus a preprocessor report (dropped embeds, stripped private references, converted wikilinks, dropped nav-sidebar lines) instead of writing the artifact to disk, so authors can confirm the output before uploading to `gno.sh`.
- Added a preprocessor warnings channel on the local serve API publish-export route so the same report is visible to UI clients.

## [1.0.1] - 2026-04-19

### Fixed

- Fixed indexing of password-protected PDFs and XLSX files so GNO records clean per-file `PERMISSION` errors, avoids leaking raw binary error text, and continues indexing the rest of the collection without noisy dependency stack traces.

## [1.0.0] - 2026-04-16

### Added

- Added true local-first encrypted publishing for `gno publish export`, including a v2 encrypted artifact envelope, local AES-GCM encryption before upload, and `--passphrase` support for encrypted exports.

### Changed

- Clarified the hosted publishing story around `gno.sh`, including the exact encrypted publish boundary: ciphertext is produced locally in GNO before upload, and readers decrypt in-browser.

### Fixed

- Fixed the encrypted publish contract so exported encrypted artifacts no longer contain plaintext note content.

## [0.42.0] - 2026-04-16

### Added

- Added the first `gno.sh` publish artifact export flow, including `gno publish export <target>` with route slug, title, summary, and visibility controls for note or collection exports.

### Fixed

- Fixed publish artifact export validation and normalization so generated artifacts are safer to import into `gno.sh`.

### Changed

- Updated README positioning and launch copy to promote the hosted `gno.sh` publishing path and show the publish reader flow more clearly.

## [0.41.1] - 2026-04-07

### Fixed

- Fixed sqlite-vec writes to replace existing chunk rows cleanly during re-embed flows, eliminating the duplicate-key warning users could hit after same-model clears or force re-embeds.
- Fixed embedding recovery so GNO now downshifts failed batches, resets disposed embedding ports, and surfaces concrete sample errors plus retry guidance instead of only reporting opaque failed-chunk counts.

## [0.41.0] - 2026-04-07

### Added

- Added embedding compatibility profiles plus safer indexing fallback behavior, including model-aware query/document formatting, batch-to-single-item embed recovery, and batched vector-query embedding in hybrid retrieval.

### Changed

- Improved the default Qwen embedding path for both indexing and retrieval while keeping the full retrieval stack intact, and documented the required `gno embed --force` or clear-and-reembed migration path for formatting/profile changes.

## [0.40.2] - 2026-04-06

### Fixed

- Fixed Web UI document layout regressions in the left outline rail, including width blowouts, sticky behavior, and long-title handling in dense note views.
- Fixed local markdown image rendering in Doc View and editor preview by resolving note-relative asset paths against the current document instead of the web root.

## [0.40.1] - 2026-04-06

### Changed

- Updated the release workflow to use `actions/download-artifact@v8` in `publish.yml`.

## [0.40.0] - 2026-04-06

### Added

- Added collection-scoped embedding ergonomics across CLI, Web UI, API, and MCP, including `gno embed [collection]` / `gno embed --collection <name>` plus collection embedding cleanup actions for stale or all vectors.
- Added `gno_clear_collection_embeddings` to MCP so agents can explicitly remove stale or all embeddings for one collection when write tools are enabled.

### Changed

- Updated CLI, MCP, Web UI, and skill docs so collection-scoped embed/re-embed/cleanup flows are documented consistently after the default embed-model switch.

## [0.39.1] - 2026-04-06

### Changed

- Clarified the upgrade path after the default embed-model switch to `Qwen3-Embedding-0.6B-GGUF`, including the explicit `gno models pull --embed` + `gno embed` re-embed step for existing collections.

## [0.39.0] - 2026-04-06

### Added

- Added a new public multilingual markdown benchmark lane for general collections, with vendored FastAPI docs fixtures, same-language and cross-language relevance cases, and committed benchmark artifacts for `bge-m3` and `Qwen3-Embedding-0.6B-GGUF`.
- Added collection-level embedding cleanup across CLI, Web UI, and API, including stale-vs-all modes and protection for vectors still shared by active documents in other collections.

### Changed

- Switched built-in preset embedding models from `bge-m3` to `Qwen3-Embedding-0.6B-GGUF` after it materially outperformed `bge-m3` on both code and multilingual prose benchmark lanes.
- Status/backlog reporting is now model-aware for the active embedding model across CLI, Web UI, SDK, and MCP, so preset/default embed-model changes immediately surface the need to re-embed.
- Preset switching in CLI/Web/API now explicitly tells users when the embedding model changed and embeddings need to be regenerated.

## [0.38.0] - 2026-04-06

### Added

- Added a collection-level model editor in the web UI, including per-role override editing, inherited-vs-overridden effective model display, and code-collection recommendations for the embedding model.
- Added richer collection API payloads plus `PATCH /api/collections/:name` so clients can inspect and update collection-scoped model overrides without hand-editing YAML.
- Added `gno collection add --embed-model` so collection-specific embedding model overrides can be set directly from the CLI.

### Changed

- Updated CLI, API, configuration, Web UI, troubleshooting, and agent-skill docs to cover collection-scoped model overrides and the follow-up embedding workflow after changing a collection's embedding model.

## [0.37.0] - 2026-04-06

### Added

- Added a retrieval-quality upgrade pass across BM25 lexical handling, code-aware chunking, terminal result hyperlinks, and per-collection model overrides.
- Added a code-embedding benchmark workflow with canonical, real-GNO, and pinned OSS benchmark slices plus a bounded autonomous search harness for comparing alternate embedding models.
- Added benchmark/result pages and documentation that now recommend `Qwen3-Embedding-0.6B-GGUF` as the current code-specialist embedding model for per-collection code overrides.
- Added ADRs for BM25 query semantics, code-aware chunking, and collection-model resolution, plus a follow-up Flow epic for more granular path/file-type model resolution.

### Fixed

- Fixed BM25 lexical search so quoted phrases, negation, hyphenated technical terms, underscores, and filepath/title/body weighting behave intentionally and are protected by regression tests.
- Fixed CLI retrieval output to emit TTY-only OSC 8 hyperlinks without leaking escape sequences into structured or non-TTY output.
- Fixed code-chunking visibility so `gno doctor` now reports the automatic code-aware chunking mode and supported extensions.
- Fixed the embedding autoresearch harness so candidate runtime wiring, dual-fixture scoring, and leaderboard/result loading work correctly in the tracked branch/CI path.

## [0.36.0] - 2026-04-06

### Added

- Added a much stronger note command palette experience in the web workspace, including place-aware creation, section-first query results, keyboard navigation that follows visible ordering, and better help/discoverability around note-native actions.

### Changed

- Rebalanced the desktop document view rails so metadata and outline stay together on the left, while properties/path and relationship panels live on the right with tighter sticky behavior for long-note reading.

### Fixed

- Fixed command palette focus/selection styling so the input no longer inherits the global outline ring and selected items are visually obvious while using arrow keys or narrowing results.
- Fixed command palette result ordering so `cmdk` no longer fights the app's grouped ordering, preventing invisible selection jumps to non-visible items.

## [0.35.0] - 2026-04-05

### Added

- Added workspace-native note authoring flows across the web workspace, including place-aware note creation from Browse, note presets, editor preset insertion, section outline/deep links, and a stronger command palette for note/navigation actions.
- Added reference-aware file operations for editable notes, including move, duplicate, folder creation, refactor warning previews, and shared note/file operation contracts that now span the Web UI, SDK, and MCP surfaces.
- Added new programmatic surfaces for note workflows: REST endpoints for note presets, sections, folder creation, file refactor planning, move, and duplicate; new MCP write tools for folder/note refactors; and SDK parity for note creation, folder creation, sections, rename, move, and duplicate.
- Added the Scholarly Dusk design-system ADR and linked the new note-workspace epics/tasks to it so future UI work stays visually coherent.

### Fixed

- Fixed Windows/macOS path normalization issues so note/file workflows and desktop runtime-layout helpers keep POSIX-stable relpaths/URIs across platforms, unblocking green Windows CI again.

## [0.34.1] - 2026-04-04

### Fixed

- Fixed the desktop release workflows to stop uploading redundant proof-only artifacts, preventing transient GitHub artifact `ENOTFOUND` failures from sinking otherwise successful macOS packaging runs.

## [0.34.0] - 2026-04-04

### Added

- Added a cross-collection Browse 2.0 workspace with a real tree sidebar, folder detail panes, and tab-scoped browse state restoration.
- Added richer document rendering in the web workspace, including clickable frontmatter links, clickable resolved wiki links in note content, and denser document metadata/frontmatter presentation.
- Added a broad website/content refresh across the homepage, feature pages, docs metadata, FAQ, and comparison pages to better position GNO as a local knowledge workspace for humans and agents.

### Fixed

- Improved graph loading by reducing redundant server-side graph work and tuning the client-side graph defaults for faster initial render.
- Improved browser smoke coverage for Browse flows and stabilized the direct-child browse API assertion in tests.

## [0.33.4] - 2026-04-03

### Fixed

- Improved web UI regression coverage with Bun-first DOM interaction tests and a repo-local browser smoke path for search, capture, and document flows.

## [0.33.3] - 2026-04-03

### Fixed

- Fixed the macOS desktop packaging workflow artifact handling so the release-manifest JSON is uploaded from the generated release directory instead of the wrong artifact root.

## [0.33.2] - 2026-04-03

### Fixed

- Fixed the macOS desktop packaging workflow to execute the release script directly in CI and validate the artifact directory in the same step, reducing ambiguity around artifact discovery failures.

## [0.33.1] - 2026-04-02

### Fixed

- Fixed the macOS desktop release workflow so notarized desktop beta artifacts are uploaded from the correct runner paths and can be attached to GitHub releases.

## [0.33.0] - 2026-04-02

### Added

- Added a packaging matrix for CLI vs desktop support on macOS and Linux, including support tiers, artifact guidance, and runtime bundling assumptions.
- Added a repo-local macOS desktop release command for the Electrobun shell that signs, notarizes, staples, and verifies versioned desktop beta zip/DMG artifacts.
- Added a macOS desktop packaging job to the release workflow so tagged releases can build notarized desktop beta artifacts in CI once the release environment is configured.

### Changed

- Installation and desktop rollout docs now describe Linux desktop as experimental and macOS desktop as the primary beta target.

## [0.32.0] - 2026-04-02

### Added

- Added `GET /api/jobs/active` so clients can discover the currently running background job without scraping a `409` error message.

### Changed

- Job-conflict `409` API responses now include structured `error.details.activeJobId` metadata.

## [0.31.2] - 2026-04-02

### Fixed

- Browse now uses the available table space more effectively for long note titles, paths, and collection names. Document titles/paths wrap cleanly, and collection chips no longer truncate similarly named collections into unreadable slivers.

## [0.31.1] - 2026-04-01

### Fixed

- Relaxed Windows-only CI assumptions in the desktop runtime-layout tests so path separator differences no longer fail the test suite on `win32`.
- Increased the Windows timeout budget for the concurrent CLI access regression test, avoiding false negatives from slower process startup on GitHub Actions runners.

## [0.31.0] - 2026-04-01

### Added

- Added first packaged `windows-x64` desktop beta build plumbing, including packaged-runtime validation, Windows packaging workflow coverage, and release-asset support for the Windows desktop zip.
- Added explicit Windows support docs covering current target scope, packaged-runtime validation, and manual validation guidance for the desktop beta.

### Changed

- `gno index <collection>` now scopes the embedding phase to that collection instead of consuming unrelated global backlog from other collections.
- Release automation now publishes the packaged Windows desktop beta zip alongside the normal npm/GitHub release flow.

### Fixed

- CLI index summaries no longer divide embed duration by `1000` twice, so long embedding runs report realistic times instead of bogus sub-second output.

## [0.30.0] - 2026-03-27

### Added

- Added `gno daemon`, a headless continuous-indexing mode that reuses GNO's existing watcher/sync/embed pipeline without starting the Web UI server.

### Changed

- Elevated the in-app workspace presentation across the web/desktop shell path with stronger visual hierarchy, cleaner tabs/footer treatment, and a more intentional dashboard/search/ask aesthetic.
- Clarified product docs around when to use the desktop app, `gno serve`, and the new headless daemon mode.

### Fixed

- Read-only CLI commands no longer take unnecessary write locks on startup, avoiding transient `database is locked` failures when they overlap with `gno update`.
- `gno daemon --no-sync-on-start` now behaves correctly and skips the initial sync pass.

## [0.29.2] - 2026-03-27

### Changed

- Refined the `gno serve` workspace presentation with a more distinctive visual language across the dashboard, tabs, search, ask, footer, and global styling, while keeping the UI fully offline-safe.

## [0.29.1] - 2026-03-27

### Fixed

- Desktop/Web document trashing no longer depends on a separately installed global `trash` CLI. GNO now uses built-in platform-aware trash behavior instead.
- Trashing a document now reports failure if the document cannot be marked inactive in the index, avoiding false-success UI states that could leave stale search results behind.

## [0.29.0] - 2026-03-27

### Added

- First public `GNO Desktop Beta` shell naming and rollout surfaces for the mac-first desktop app path.
- Full desktop-beta onboarding flow in the Web UI and desktop shell, including folder setup, plain-language preset selection, health checks, bootstrap/runtime visibility, connector center, import preview, app tabs, file lifecycle actions, and recovery history.
- Explicit in-wizard sync progress plus clearer blocked-state handling for first indexing and embedding completion.

### Changed

- `slim-tuned` is now the built-in default preset, using the fine-tuned expansion model while keeping the same embed, rerank, and answer models as `slim`.
- Fresh onboarding now skips the model-prep step when the active preset is already ready.
- Desktop shell now exposes standard edit menu actions so paste/select-all work like a normal app.

### Fixed

- Collection add no longer throws a false “Collection not found after add” error after successful mixed-case name normalization.
- Fresh sandboxes and alternate runtime launches no longer mis-detect model readiness when `GNO_CACHE_DIR` already points at a `models` directory.
- No-op `Update All` runs now report a stable up-to-date result instead of flashing away.
- Onboarding sync/add flows now trigger embedding immediately when models are ready, preventing the final step from looking stuck after indexing starts.

## [0.28.2] - 2026-03-23

### Fixed

- Updated the validated dev-tooling dependency batch: `@biomejs/biome`, `@types/react`, `lefthook`, `oxlint-tsgolint`, `playwright`, and `ultracite`.

## [0.28.1] - 2026-03-23

### Fixed

- Updated `@modelcontextprotocol/sdk` to `1.27.1` in a narrow follow-up security/maintenance bump after the stale grouped dependency PR failed local validation.

## [0.28.0] - 2026-03-23

### Fixed

- `gno embed` now requests full embedding threads from `node-llama-cpp` and uses an adaptive embedding-context pool on CPU-only machines, with graceful fallback when extra contexts cannot be created. Thanks @riyadist for the report and repro details.

## [0.27.3] - 2026-03-23

### Fixed

- Excluded the archived `desktop/electrobun-spike` workspace from root type-aware lint/typecheck so CI and patch publishes no longer fail on unresolved spike-only Electrobun imports.

## [0.27.2] - 2026-03-23

### Fixed

- Fell back gracefully for unsupported markdown fence languages in the Web UI, including Obsidian-style ````tasks` blocks that previously crashed document rendering with a frontend ShikiError. Thanks @almino for the report.

## [0.27.1] - 2026-03-22

### Fixed

- Normalized created `gno://` document URIs to POSIX-style forward slashes on Windows so editable-copy responses and related create flows no longer return backslash-separated URIs.

## [0.27.0] - 2026-03-22

### Added

- Safe document capability metadata across the API, CLI `gno get`, SDK, and MCP so callers can distinguish editable markdown/plaintext documents from read-only converted source files.
- Read-only handling plus editable-copy creation for converted PDF/DOCX-style documents in the Web UI.
- Deep links for document view/edit routes with source-view line targeting and exact-hit navigation from search results.
- Watch-driven document event streaming for live refresh and external-change awareness in Search, Browse, Doc View, and the editor.
- Wiki-link autocomplete and linked-note creation in both the full editor and Quick Capture.
- A fast `Cmd/Ctrl+K` quick switcher with recent-document tracking and note-creation handoff.
- Local editor snapshot history with restore support after save conflicts or mistaken edits.
- Updated skill guidance for editable vs read-only document handling and richer `gno get --json` capability metadata.

### Changed

- Web/docs/website positioning now describe GNO as a safer markdown-first local workspace for agent-centric teams rather than only a retrieval layer alongside Obsidian.
- `gno_get` / `GET /api/doc` / related docs now return richer source metadata and capability metadata.

### Fixed

- Preserved deep-link line targets when navigating from document view into edit mode.
- Avoided editable-copy navigation races by waiting for the copied markdown document to become queryable before opening it.
- Removed the ugly quick-switcher focus ring/outline clash from the command input.

## [0.26.0] - 2026-03-22

### Added

- OpenCode and OpenClaw as skill install targets (`--target opencode`, `--target openclaw`).
- `--target all` now installs to all 4 targets (`claude`, `codex`, `opencode`, `openclaw`).
- MCP parameter descriptions on all 19 tools, including clearer usage guidance across roughly 60 parameters.
- MCP tool descriptions with improved usage guidance, async/job polling hints, and ref-format examples.
- Skill documentation for `--since`, `--until`, `--exclude`, `--intent`, and `--query-mode`.
- Skill sections for Document Retrieval, Links & Similarity, and search-then-get JSON pipelines.

### Fixed

- `--target all` for skill install/uninstall was previously hardcoded to `claude` + `codex` only.

## [0.25.1] - 2026-03-22

### Changed

- Expanded the bundled GNO agent skill with missing CLI retrieval flags, structured query mode guidance, `get`/`multi-get` retrieval examples, search-then-get JSON pipelines, and document links/similarity commands for better agent usability.

## [0.25.0] - 2026-03-21

### Added

- Preset-aware retrieval depth policy across Web, CLI, and MCP: `Balanced` now enables expansion on `slim` / `slim-tuned`, while `Thorough` widens the rerank candidate pool for best recall.
- Explicit model-role split for presets and runtime: `expand` now controls query expansion separately from `gen` answer generation, with updated config/docs, model management UX, and CLI output.
- Collection management discoverability and actions across the web UI, including direct `/collections` navigation, inline reindex affordances, and clickable collection surfaces that lead into filtered Browse views.

### Changed

- Ask/Search preset UI now presents the active preset as a bundle and shows separate expansion vs answer roles instead of implying the retrieval-tuned model is the answer model.
- The live `slim-tuned` preset guidance now pairs the promoted retrieval expansion model with a separate larger answer model.

## [0.24.0] - 2026-03-10

### Added

- First-class structured multi-line query documents using `term:`, `intent:`, and `hyde:` across CLI `query`/`ask`, REST `/api/query` and `/api/ask`, MCP `gno_query`, SDK `query`/`ask`, and Web Search/Ask text boxes.
- Dedicated structured syntax reference doc plus updated CLI/API/MCP/SDK/Web docs.

## [0.23.0] - 2026-03-10

### Added

- First stable SDK / library mode at the package root via `createGnoClient(...)`, with inline-config and file-backed startup, direct retrieval/document methods, and programmatic `update` / `embed` / `index` flows.

### Changed

- Package root now resolves to the SDK surface; the CLI remains available through the `gno` binary and `./cli` export.
- Added full SDK docs, README coverage, architecture notes, website nav, homepage copy, and a dedicated SDK feature page.

## [0.22.6] - 2026-03-10

### Fixed

- Stabilized cross-platform research tests by replacing one remaining generated-artifact assertion with direct filtering logic checks.

## [0.22.5] - 2026-03-10

### Changed

- Updated the main README, CLI examples, docs page, homepage bento, and fine-tuned model feature page to point at the current promoted `slim-tuned` retrieval model and Hugging Face install flow.

## [0.22.4] - 2026-03-10

### Changed

- Updated the public fine-tuned model docs and feature pages to point at the published Hugging Face model, the current promoted slim retrieval preset, and the canonical HF-backed install flow instead of local-only paths.

## [0.22.3] - 2026-03-10

### Fixed

- Relaxed the autonomous confirmation test so release CI no longer depends on a locally generated repeat-benchmark artifact being committed.

## [0.22.2] - 2026-03-10

### Fixed

- Made retrieval research tests portable in CI by removing machine-specific absolute paths and using repo-root-relative fixture resolution.

## [0.22.1] - 2026-03-10

### Fixed

- Included fine-tuning helper libraries and benchmark fixture JSON used by the retrieval research scripts/tests so release CI can resolve the research sandbox correctly on clean machines.

## [0.22.0] - 2026-03-10

### Added

- Retrieval fine-tuning sandbox now supports real local MLX LoRA training, portable GGUF export, automatic checkpoint selection, promotion bundles, and repeatable benchmark comparisons.
