These notes describe customer-facing behaviour: new APIs, changed defaults, platform support, and breaking changes. The full changelog is also available in the [GitHub repository](https://github.com/opennav-ai/opennav-ai/blob/main/packages/opennav/CHANGELOG.md). ## 0.2.0 — 2026-06-14 [Section titled “0.2.0 — 2026-06-14”](#020--2026-06-14) ### Server-side content negotiation [Section titled “Server-side content negotiation”](#server-side-content-negotiation) `OpenNavServer` gives every server-rendered page a Markdown representation through standard HTTP `Accept` header negotiation. Three new methods on `OpenNavServer` let you pick the right level of control: | Method | When to use | | --- | --- | | `negotiate({ request, htmlResponse })` | Full pipeline — accept header → decision → response. The default for most routes. | | `accept(request)` | Need the Accept decision *before* fetching or rendering expensive page content. Sync, no I/O. | | `toMarkdown({ request, htmlResponse })` | Already know Markdown is needed (static `.md` cache miss, markdown-only endpoint). | Read the [server-side guide](https://docs.opennav.ai/frameworks/server-side/index.md) for framework-specific examples for Hono, Astro SSR, Next.js, and Cloudflare Workers. ### Other additions [Section titled “Other additions”](#other-additions) - **Accept header negotiation** — RFC 9110-compliant Accept header parsing with q-value weighting, wildcard matching, and client-order tiebreaking. - **Layout stripping** — remove nav, header, footer, and chrome elements before Markdown conversion with `contentExtraction: { stripLayout: true }`. - **`Vary: Accept`** on all negotiated responses so caches keep HTML and Markdown representations separate. - **`Link: rel="alternate"`** on HTML responses advertising the Markdown representation so agents can discover it. - **Cloudflare Pages Functions guide** — static `.md` priority with runtime fallback using `opennav.accept()` to avoid wasted CPU. ## 0.1.2 — 2026-06-07 [Section titled “0.1.2 — 2026-06-07”](#012--2026-06-07) - Documentation site updated to use the published `@opennav-ai/opennav` package from npm instead of workspace references. - GitHub repository links added to the docs site header and navigation. ## 0.1.1 — 2026-06-06 [Section titled “0.1.1 — 2026-06-06”](#011--2026-06-06) - `LICENSE` file added to the published npm package so license information appears on npmjs.com. ## 0.1.0 — 2026-06-06 [Section titled “0.1.0 — 2026-06-06”](#010--2026-06-06) Initial public release of `@opennav-ai/opennav`. - **`OpenNavStaticSite`** — generate agent-readable files (`index.md`, `llms.txt`, `llms-full.txt`, `.well-known/opennav.json`, `robots.txt`) from a static output directory. - **`opennav build` CLI** — command-line entry point with `--output`, `--site-url`, `--site-name`, `--platform`, `--dry-run`, and `--full-run` flags. - **`OpenNavAstro`** — Astro integration that runs after `astro build`. - **`OpenNavNext`** — Next.js config wrapper for static export builds. - **Cloudflare Pages `_headers`** — proper content types for `.md`, `llms.txt`, and `opennav.json` artifacts. - **Build fingerprinting** — every generated file is stamped with a stable SHA-256 fingerprint so agents and caching layers can detect changes.
