## [2.2.0] - 2026-04-08

### Changed

- Migrated repository and CI from GitHub to GitLab.
- Replaced GitHub Actions workflow with GitLab CI pipeline.

## [2.1.0] - 2026-04-08

### Added

- **RSS `<content:encoded>`** -- full HTML content now emitted alongside `<description>` when `item.content` is set. Platforms like Dev.to read this element for syndicated post bodies. The `content:` namespace was already declared but unused; it is now active.
- **RSS `<media:content>`** -- `FeedItem.image` now renders as `<media:content url="..." medium="image" />` in RSS output. The `xmlns:media` namespace is conditionally declared only when items have images.
- **Atom item images** -- `FeedItem.image` now renders as `<link rel="enclosure" href="..." type="image/..." />` in Atom entries, with MIME type inferred from the URL file extension.
- **Custom extensions** -- new `extensions` field on `Feed` and `FeedItem` for injecting arbitrary XML namespaces, XML elements, and JSON Feed properties without library changes. Supports Dublin Core, GeoRSS, Spotify podcast namespace, or any custom namespace.
- **XSLT stylesheet support** -- new `stylesheet` option in `FeedOptions` emits a `<?xml-stylesheet?>` processing instruction for browser-friendly RSS/Atom rendering.
- **WebSub hub link** -- new `hub` field in `feedLinks` emits `<atom:link rel="hub">` (RSS), `<link rel="hub">` (Atom), and `hubs` array (JSON Feed) for real-time push notification support.
- **`FeedItem.image` URL validation** -- image URLs are now validated like other URL fields.
- **`FeedBuilder` methods**: `.hub()`, `.extensions()`, `.stylesheet()`.
- **Exported `XmlNode` type** for building custom extension elements.

### Changed

- RSS/Atom renderer signatures now accept an options object instead of a boolean `compact` parameter (internal change, public API unchanged).

- Complete rewrite with unified data model for RSS 2.0, Atom 1.0, and JSON Feed 1.1.
- Fluent `FeedBuilder` API.
- Full iTunes/podcast namespace support.
- Whitelist-based HTML sanitization with XSS protection.
- Comprehensive input validation with `FeedValidationError`.
- Feed pagination via `nextUrl`.
- Zero dependencies, dual ESM + CJS build.
