The v0.13.0 release is the largest Hugo release to date. The release introduced
some long sought after features (pagination, sequencing, data loading, tons of
template improvements) as well as major internal improvements. In addition to
the code changes, the Hugo community has grown significantly and now has over
3000 stars on GitHub, 134 contributors, 24 themes and 1000s of happy users.

This release represents **448 contributions by 65 contributors**

A special shout out to [@bep](https://github.com/bep) and
[@anthonyfok](https://github.com/anthonyfok) for their new role as Hugo
maintainers and their tremendous contributions this release.

### New major features
- Support for [data files](http://gohugo.io/extras/datafiles/) in [YAML](http://yaml.org/),
  [JSON](http://www.json.org/), or [TOML](https://github.com/toml-lang/toml)
  located in the `data` directory ([#885](https://github.com/spf13/hugo/issues/885))
- Support for [dynamic content](http://gohugo.io/extras/dynamiccontent/) by loading JSON & CSV
  from remote sources via GetJson and GetCsv in short codes or other layout
  files ([#748](https://github.com/spf13/hugo/issues/748))
- [Pagination support](http://gohugo.io/extras/pagination/) for home page, sections and
  taxonomies ([#750](https://github.com/spf13/hugo/issues/750))
- Universal sequencing support
  - A new, generic Next/Prev functionality is added to all lists of pages
    (sections, taxonomies, etc.)
  - Add in-section [Next/Prev](http://gohugo.io/templates/variables/) content pointers
- `Scratch` -- [a "scratchpad"](http://gohugo.io/extras/scratch) for your node- and page-scoped
  variables
- [Cross Reference](http://gohugo.io/extras/crossreferences/) support to easily link documents
  together with the ref and relref shortcodes.
- [Ace](http://ace.yoss.si/) template engine support ([#541](https://github.com/spf13/hugo/pull/541))
- A new [shortcode](http://gohugo.io/extras/shortcodes/) token of `{{</* */>}}` (raw HTML)
  alongside the existing `{{%/* */%}}` (Markdown)
- A top level `Hugo` variable (on Page & Node) is added with various build
  information
- Several new ways to order and group content:
  - `ByPublishDate`
  - `GroupByPublishDate(format, order)`
  - `GroupByParam(key, order)`
  - `GroupByParamDate(key, format, order)`
- Hugo has undergone a major refactoring, with a new handler system and a
  generic file system. This sounds and is technical, but will pave the way for
  new features and make Hugo even speedier

### Notable enhancements to existing features

  better error messages.

    operators `==`, `eq`; `!=`, `<>`, `ne`; `>=`, `ge`; `>`, `gt`; `<=`,
    `le`; `<`, `lt`; `in`, `not in`
  - `where` template function now also accepts dot chaining key argument
    (e.g. `"Params.foo.bar"`)
- New template functions:
  - `apply`
  - `chomp`
  - `delimit`
  - `sort`
  - `markdownify`
  - `in` and `intersect`
  - `trim`
  - `replace`
  - `dateFormat`
- Several [configurable improvements related to Markdown
  rendering](http://gohugo.io/overview/configuration/#configure-blackfriday-rendering:a66b35d20295cb764719ac8bd35837ec):
  - Configuration of footnote rendering
