-In Hugo 0.18 every piece of content is a `Page`  ({{<gh 2297 >}}) and this means that every page, including the home page, can have a content file with frontmatter.
+Today, we're exited to release the much-anticipated Hugo 0.18!

+We're heading towards the end of the year 2016, and we can look back on three releases and a steady growing community around the project.
+This release includes **over 220 contributions by nearly 50 contributors** to the main codebase.
+Since the last release, Hugo has **gained 1750 stars and 27 additional themes**.

+{{< gh "@bep" >}} once again took the lead of Hugo and contributed a significant amount of additions.
+Also a big shoutout to {{< gh "@digitalcraftsman" >}} for his relentless work on keeping the documentation and the themes site in pristine condition,

+
+We wish you all a Merry Christmas and a Happy New Year.<br>

+
+## Highlights
+
+The primary new feature in Hugo 0.18 is that every piece of content is now a `Page` ({{<gh 2297>}}).
+This means that every page, including the home page, can have a content file with frontmatter.
+Not only is this a much simpler model to understand, it is also faster and paved the way for several important new features:
 
 * Enable proper titles for Nodes {{<gh 1051>}}
 * Sitemap.xml should include nodes, as well as pages {{<gh 1303>}}

 * Allow home page to be easily authored in markdown {{<gh 720>}}
 * Minimalist website with homepage as content {{<gh 330>}}
 
+Hugo again continues its trend of each release being faster than the last. It's quite a challenge to consistently add significant new functionality and simultaneously dramatically improve performance. Running [this benchmark]( https://github.com/bep/hugo-benchmark) with [these sites](https://github.com/bep/hugo-benchmark/tree/master/sites) (renders to memory) shows about	60% reduction in time spent and 30% reduction in memory usage compared to Hugo 0.17.
+
+## Other New Features
+
+* Every `Page` now has a `Kind` property. Since everything is a `Page` now, the `Kind` is used to differentiate different kinds of pages.
+  Possible values are `page`, `home`, `section`, `taxonomy`, and `taxonomyTerm`.
+  (Internally, we also define `RSS`, `sitemap`, `robotsTXT`, and `404`, but those have no practical use for end users at the moment since they are not included in any collections.)
+* Add a `GitInfo` object to `Page` if `enableGitInfo` is set. It then also sets `Lastmod` for the given `Page` to the author date provided by Git. {{<gh 2291>}}
+* New template functions:
+  * Add `imageConfig` function {{<gh 2677>}}
+  * Add `sha256` function {{<gh 2762>}}
+  * Add `partialCached` template function {{<gh 1368>}}
+* Add shortcode to display Instagram images {{<gh 2690>}}
+* Add `noChmod` option to disable perm sync {{<gh 2749>}}
+* Add `quiet` build mode {{<gh 1218>}}
 
 
+## Notices
 
+* `.Site.Pages` will now contain *several kinds of pages*, including regular pages, sections, taxonomies, and the home page.
+  If you want a specific kind of page, you can filter it with `where` and `Kind`.
+  `.Site.RegularPages` is a shortcut to the page collection you have been used to getting.
+* `RSSlink` is now deprecated.  Use `RSSLink` instead.
+  Note that in Hugo 0.17 both of them existed, so there is a fifty-fifty chance you will not have to do anything
+  (if you use a theme, the chance is close to 0), and `RSSlink` will still work for two Hugo versions.
 
+## Fixes
+
+* Revise the `base` template lookup logic so it now better matches the behavior of regular templates, making it easier to override the master templates from the theme {{<gh 2783>}}
+* Add workaround for `block` template crash.
+  Block templates are very useful, but there is a bug in Go 1.6 and 1.7 which makes the template rendering crash if you use the block template in more complex scenarios.
+  This is fixed in the upcoming Go 1.8, but Hugo adds a temporary workaround in Hugo 0.18. {{<gh 2549>}}
+* All the `Params` configurations are now case insensitive {{<gh 1129>}} {{<gh 2590>}} {{<gh 2615>}}
+* Make RawContent raw again {{<gh 2601>}}
+* Fix archetype title and date handling {{<gh 2750>}}
+* Fix TOML archetype parsing in `hugo new` {{<gh 2745>}}
+* Fix page sorting when weight is zero {{<gh 2673>}}
+* Fix page names that contain dot {{<gh 2555>}}
+* Fix RSS Title regression {{<gh 2645>}}
+* Handle ToC before handling shortcodes {{<gh 2433>}}
+* Only watch relevant themes dir {{<gh 2602>}}
+* Hugo new content creates TOML slices with closing bracket on new line {{<gh 2800>}}
+
+## Improvements
+
+* Add page information to error logging in rendering {{<gh 2570>}}
+* Deprecate `RSSlink` in favor of `RSSLink`
+* Make benchmark command more useful {{<gh 2432>}}
+* Consolidate the `Param` methods {{<gh 2590>}}
+* Allow to set cache dir in config file
+* Performance improvements:
+  * Avoid repeated Viper loads of `sectionPagesMenu` {{<gh 2728>}}
+  * Avoid reading from Viper for path and URL funcs {{<gh 2495>}}
+  * Add `partialCached` template function. This can be a significant performance boost if you have complex partials that does not need to be rerendered for every page. {{<gh 1368>}}
+
+## Documentation Updates
+
+* Update roadmap {{<gh 2666>}}
+* Update multilingual example {{<gh 2417>}}
+* Add a "Deployment with rsync" tutorial page {{<gh 2658>}}
+* Refactor `/docs` to use the `block` keyword {{<gh 2226>}}
