 # Changelog
 
+## 0.6.0 (unreleased)
+
+### Breaking
+- `earlier/later` and `lighter/heavier` are not set anymore on pages when rendering
+a section
+- The table of content for a page/section is now only available as the `toc` variable when
+rendering it and not anymore on the `page`/`section` variable
+- Default directory for `load_data` is now the root of the site instead of the `content` directory
+- Change variable sent to the sitemap template, see documentation for details
+
+### Other
+- Add support for content in multiple languages
+- Lower latency on serve before rebuilding from 2 to 1 second
+- Allow processing PNG and produced images are less blurry
+- Add an id (`zola-continue-reading`) to the paragraph generated after a summary
+- Add Dracula syntax highlighting theme
+- Fix using inline styles in headers
+- Fix sections with render=false being shown in sitemap
+- Sitemap is now split when there are more than 30 000 links in it
+- Add link to sitemap in robots.txt
+- Markdown rendering is now fully CommonMark compliant
+- `load_data` now defaults to loading file as plain text, unless `format` is passed
+or the extension matches csv/toml/json
+- Sitemap entries get an additional `extra` field for pages only
+- Add a `base-path` command line option to `build` and `serve`
+
+
 ## 0.5.1 (2018-12-14)
 
 - Fix deleting markdown file in `zola serve`

+Zola supports having a site in multiple languages.
+
+## Configuration
+To get started, you will need to add the languages you want to support
+to your `config.toml`. For example:
+
+```toml
+languages = [
+    {code = "fr", rss = true}, # there will be a RSS feed for French content
+    {code = "it"}, # there won't be a RSS feed for Italian content
+]
+```
+
+If you want to use per-language taxonomies, ensure you set the `lang` field in their
+configuration.
+
+## Content
+Once the languages are added in, you can start to translate your content. Zola
+uses the filename to detect the language:
+
+- `content/an-article.md`: this will be the default language
+- `content/an-article.fr.md`: this will be in French
+
+If the language code in the filename does not correspond to one of the languages configured,
+an error will be shown.
+
+If your default language has an `_index.md` in a directory, you will need to add a `_index.{code}.md`
+file with the desired front-matter options as there is no language fallback.
+
+## Output
+Zola outputs the translated content with a base URL of `{base_url}/{code}/`.
+The only exception to that is if you are setting a translated page `path` directly in the front-matter.

 #### Data Caching
 
-Data file loading and remote requests are cached in memory during build, so multiple requests aren't made to the same endpoint. URLs are cached based on the URL, and data files are cached based on the files modified time. The format is also taken into account when caching, so a request will be sent twice if it's loaded with 2 different formats.

 Zola will look for a `sitemap.xml` file in the `templates` directory or

+If your site has more than 30 000 pages, it will automatically split

-The sitemap template gets four variables in addition of the config:
+> All formats limit a single sitemap to 50MB (uncompressed) and 50,000 URLs. 
+> If you have a larger file or more URLs, you will have to break your list into multiple sitemaps. 
+> You can optionally create a sitemap index file (a file that points to a list of sitemaps) and submit that single index file to Google.
 
-- `pages`: all pages of the site
+In such a case, Zola will use a template called `split_sitemap_index.xml` to render the index sitemap.
-- `sections`: all sections of the site, including an index section
-- `tags`: links the tags page and individual tag page, empty if no tags
