# Changelog

## 0.16.0 (unreleased)

### Breaking

- Switch to pulldown-cmark anchor rather than ours, some (very niche) edge cases are not supported anymore, you can
also specify classes on headers now
- Now outputs empty taxonomies instead of ignoring them
- Unify all pages sorting variable names in templates to `lower`/`higher` in order to make it easy to re-use templates and it
was becoming hard to come up with names

- `zola serve/build` can now run from anywhere in a zola directory
- Add XML support to `load_data`

- `skip_prefixes` is now checked before parsing external link URLs
- Add `render` attribute to taxonomies configuration in `config.toml`, for when you don't want to render
any pages related to that taxonomy
- Serialize `transparent` field from front-matter of sections
- Use Zola Tera instance for markdown filter: this means you have access to the same Tera functions as in shortcodes
- Ignore sections with `render=false` when looking for path collisions
- Add support for backlinks

## 0.14.0 (2021-07-19)

### Breaking

- Newlines are now required after the closing `+++` of front-matter
- `resize_image` now returns an object: `{url, static_path}` instead of just the URL so you can follow up with other functions on the new file if needed
- `get_file_hash` now has the `base64` option set to `true` by default (from `false`) since it's mainly used for integrity hashes which are base64
- i18n rework: languages now have their sections in `config.toml` to set up all their options
  1. taxonomies don't have a `lang` anymore in the config, you need to declare them in their respective language section
  2. the `config` variable in templates has been changed and is now a stripped down language aware version of the previous `config`
  object
  3. Search settings are now language specific
  4. Translations are now nested in the languages table
- Paths unification: 
  1. `get_url` does not load automatically from the `static` folder anymore
  2. New path resolving logic for all on-disk files: replace `@/` by `content/`, trim leading `/` and 
     search in $BASE_DIR + $path, $BASE_DIR + static + $path and $BASE_DIR + content + $path
  3. `get_file_hash` now returns base64 encoded hash by default
  4. all functions working on files can now only load files in the Zola directory
  5. `resize_image` return value has changed
  6. `page.assets` now start with a `/` to match `section.assets` and other paths

## 0.11.0 (2020-05-25)

### Breaking
- RSS feed support has been altered to allow, *and default to*, Atom feeds, Atom being technically superior and just as widely-supported in normal use cases.
  - New config value `feed_filename`, defaulting to `atom.xml` (change to `rss.xml` to reinstate the old behaviour)

  - Config value `languages.*.rss` is renamed to `languages.*.feed`
  - Config value `generate_rss` is renamed to `generate_feed`
  - Taxonomy value `rss` is renamed to `feed`

  Users with existing feeds should either set `feed_filename = "rss.xml"` in config.toml to keep things the same, or set up a 3xx redirect from rss.xml to atom.xml so that existing feed consumers aren’t broken.

- The feed template variable `last_build_date` is renamed to `last_updated` to more accurately reflect its semantics
- The sitemap template’s `SitemapEntry` type’s `date` field has been renamed to `updated` to reflect that it will use the `updated` front-matter field if available, rather than `date`
- Code blocks are now wrapped in `<pre><code>` instead of just `<pre>`

### Other

- Add `lang` to the feed template context
- Add `taxonomy` and `term` to the feed template context for taxonomy feeds
- Fix link checker not looking for anchor with capital id/name
- Pass missing `lang` template parameter to taxonomy list template
