-## **0.18.1** December 30th 2016
+
+# **0.19** February 27th 2017
+
+We're happy to announce the first release of Hugo in 2017.
+
+This release represents **over 180 contributions by over 50 contributors** to the main Hugo code base. Since last release Hugo has **gained 1450 stars, 35 new contributors and 15 additional themes.**
+
+Hugo now has:
+
+- 15200+ stars
+- 470+ contributors
+- 151+ themes
+
+Furthermore, Hugo has its own Twitter account ([@gohugoio](https://twitter.com/gohugoio)) where we share bite-sized news and themes from the Hugo community.
+
+{{< gh "@bep" >}} leads the Hugo development and once again contributed a significant amount of additions. Also a big shoutout to  {{< gh "chaseadamsio" >}} for the Emacs Org-mode support, {{< gh "@digitalcraftsman" >}} for his relentless work on keeping the documentation and the themes site in pristine condition, {{< "@fj" >}}  for his work on revising the `params` handling in Hugo, and {{< gh "@moorereason" >}} and {{< gh "@bogem" >}} for their ongoing contributions. 
+
+## Highlights
+Hugo `0.19` brings native Emacs Org-mode content support ({{<gh 1483>}}), big thanks to {{< gh "chaseadamsio" >}}.
+
+Also, a considerably amount of work have been put into cleaning up the Hugo source code, in an issue titled [Refactor the globals out of site build](https://github.com/spf13/hugo/issues/2701). This is not immediately visible to the Hugo end user, but will speed up future development.
+
+Hugo `0.18` was bringing full-parallel page rendering, so workarounds depending on rendering order did not work anymore, and pages with duplicate target paths (common examples would be `/index.md` or `/about/index.md`) would now conflict with the home page or the section listing.
+
+With Hugo `0.19`, you can control this behaviour by turning off page types you do not want ({{<gh 2534 >}}). In its most extreme case, if you put the below setting in your `config.toml`, you will get **nothing!**:
+
+```
+disableKinds = ["page", "home", "section", "taxonomy", "taxonomyTerm", "RSS", "sitemap", "robotsTXT", "404"]
+```
+## Other New Features
+
+* Add ability to sort pages by frontmatter parameters, enabling easy custom "top 10" page lists. {{<gh 3022 >}}
+* Add `truncate` template function {{<gh 2882 >}}
+* Add `now` function, which replaces the now deprecated `.Now` {{<gh 2882 >}}
+* Make RSS item limit configurable {{<gh 3035 >}}
+
+## Enhancements
+*  Enhance `.Param` to permit arbitrarily nested parameter references {{<gh 2598 >}}
+* Use `Page.Params` more consistently when adding metadata {{<gh 3033 >}}
+* The `sectionPagesMenu` feature ("Section menu for the lazy blogger") is now integrated with the section content pages. {{<gh 2974 >}}

+* Make template funcs like `findRE` and friends more liberal in what argument types they accept {{<gh 3018 >}} {{<gh 2822 >}}
+* Improve generation of OpenGraph date tags {{<gh 2979 >}}
+
+## Notes
+
+* `sourceRelativeLinks` is now deprecated and will be removed in Hugo `0.21` if  no one is stepping up to the plate and fixes and maintains this feature. {{<gh 3028 >}}
