-## New features
+### New features
 * new `hugo import jekyll` command. {{< gh 1469 >}}
 * The new `Param` convenience method on `Page` and `Node` can be used to get the most specific parameter value for a given key. {{< gh 1462 >}}
 * Several new information elements have been added to `Page` and `Node`:
     * `RuneCount`: The number of [runes](http://blog.golang.org/strings) in the content, excluding any whitespace. This may be a good alternative to `.WordCount`  for Japanese and other CJK languages where a word-split by spaces makes no sense.  {{< gh 1266 >}}
 	* `RawContent`: Raw Markdown as a string. One use case may be of embedding remarkjs.com slides.
 	* `IsHome`: tells the truth about whether you're on the home page or not.
 
-## Improvements
+### Improvements
 * `hugo server` now builds ~30%+ faster by rendering to memory instead of disk. To get the old behavior, start the server with `--renderToDisk=true`.
 * Hugo now supports dynamic reloading of the config file when watching.
 * We now use a custom-built `LazyFileReader` for reading file contents, which means we don't read media files in `/content` into memory anymore -- and file reading is now performed in parallel on multicore PCs. {{< gh 1181 >}}

-## Bugfixes
+### Bugfixes
 * Fix data races in page sorting and page reversal. These operations are now also cached. {{< gh 1293 >}}
 * `page.HasMenuCurrent()` and `node.HasMenuCurrent()` now work correctly in multi-level nested menus.
 * Support `Fish and Chips` style section titles. Previously, this would end up as  `Fish And Chips`. Now, the first character is made toupper, but the rest are preserved as-is. {{< gh 1176 >}}
 * Hugo now removes superfluous p-tags around shortcodes. {{< gh 1148 >}}
 
-## Notices
+### Notices
 * `hugo server` will watch by default now.
 * Some fields and methods were deprecated in `0.14`. These are now removed, so the error message isn't as friendly if you still use the old values. So please change:
 	*   `getJson` to `getJSON`, `getCsv` to `getCSV`, `safeHtml` to
   `safeHTML`, `safeCss` to `safeCSS`, `safeUrl` to `safeURL`, `Url` to `URL`,
   `UrlPath` to `URLPath`, `BaseUrl` to `BaseURL`, `Recent` to `Pages`.
 
+### Known Issues
+
+Using the Hugo v0.15 32-bit Windows or ARM binary, running `hugo server` would crash or hang due to a [memory alignment issue](https://golang.org/pkg/sync/atomic/#pkg-note-BUG) in [Afero](https://github.com/spf13/afero).  The bug was discovered shortly after the v0.15.0 release and has since been [fixed](https://github.com/spf13/afero/pull/23) by {{< gh "@tpng" >}}.  If you encounter this bug, you may either compile Hugo v0.16-DEV from source, or use the following solution/workaround:
+
+* **64-bit Windows users: Please use [hugo_0.15_windows_amd64.zip](https://github.com/spf13/hugo/releases/download/v0.15/hugo_0.15_windows_amd64.zip)** (amd64 == x86-64).  It is only the 32-bit hugo_0.15_windows_386.zip that crashes/hangs (see {{< gh 1621 >}} and {{< gh 1628 >}}).
+* **32-bit Windows and ARM users: Please run `hugo server --renderToDisk` as a workaround** until Hugo v0.16 is released (see [“hugo server” returns runtime error on armhf](https://discuss.gohugo.io/t/hugo-server-returns-runtime-error-on-armhf/2293) and {{< gh 1716 >}}).
