## Atom 1.0 Feeds

Every collection with `has_rss = true` now generates both `feed.xml` (RSS 2.0) and `atom.xml` (Atom 1.0). Atom feeds include all required elements per RFC 4287: `<updated>`, `<id>`, `<author>`, and `<link rel="self">`.

- Per-collection and per-language feeds are generated automatically
- All 10 bundled themes include `<link rel="alternate" type="application/atom+xml">` autodiscovery
- No configuration changes needed — if you have RSS, you now have Atom too

## Redirect Aliases via Frontmatter

Add `aliases` to any page's frontmatter to create redirects from old URLs:

```yaml
---
title: My Post
aliases:
  - /old-url
  - /legacy/path
---
```

During build, seite generates:
- A lightweight HTML redirect file at each alias path with `<meta http-equiv="refresh">` and `<link rel="canonical">`
- A `_redirects` file with 301 status codes for Netlify and Cloudflare Pages compatibility

Security: alias paths are validated against path traversal and HTML-escaped in redirect output.

## Upgrade Path

- `seite upgrade` documents the new features in CLAUDE.md for existing projects
- Custom `templates/base.html` users get a hint to add Atom autodiscovery (bundled themes are updated automatically)
