8 The v0.15.0 Hugo release brings a lot of polish to Hugo. Exactly 6 months after the 0.14 release, Hugo has seen massive growth and changes. Most notably, this is Hugo's first release under the Apache 2.0 license. With this license change we hope to expand the great community around Hugo and make it easier for our many users to contribute. This release represents over **377 contributions by 87 contributors** to the main Hugo repo and hundreds of improvements to the libraries Hugo uses. Hugo also launched a [new theme showcase](http://themes.gohugo.io) and participated in [Hacktoberfest](https://hacktoberfest.digitalocean.com).

10 Hugo now has:
11 - 6700 (+2700) stars on GitHub
12 - 235 (+75) contributors
13 - 65 (+30) themes
14
15 **Template Improvements:** This release takes Hugo to a new level of speed and usability. Considerable work has been done adding features and performance to the template system which now has full support of Ace, Amber and Go Templates.
16
17 **Hugo Import:** Have a Jekyll site, but dreaming of porting it to Hugo? This release introduces a new `hugo import jekyll`command that makes this easier than ever.
18
19 **Performance Improvements:** Just when you thought Hugo couldn't get any faster, Hugo continues to improve in speed while adding features. Notably Hugo 0.15 introduces the ability to render and serve directly from memory resulting in 30%+ lower render times.

21 Huge thanks to all who participated in this release. A special thanks to [@bep](https://github.com/bep) who led the development of Hugo this release again, [@anthonyfok](https://github.com/anthonyfok), [@eparis](https://github.com/eparis), [@tatsushid](https://github.com/tatsushid) and [@DigitalCraftsman](https://github.com/digitalcraftsman/).

23 ## New features
24 - new `hugo import jekyll` command. [#1469](https://github.com/spf13/hugo/pull/1469)
25 - The new `Param` convenience method on `Page` and `Node` can be used to get the most specific parameter value for a given key. [#1462](https://github.com/spf13/hugo/issues/1462)
26 - Several new information elements have been added to `Page` and `Node`:
27 - `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. [#1266](https://github.com/spf13/hugo/issues/1266)
28 - `RawContent`: Raw Markdown as a string. One use case may be of embedding remarkjs.com slides.
29 - `IsHome`: tells the truth about whether you're on the home page or not.

31 ## Improvements
32 - `hugo server` now builds ~30%+ faster by rendering to memory instead of disk. To get the old behavior, start the server with `--renderToDisk=true`.
33 - Hugo now supports dynamic reloading of the config file when watching.
34 - 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. [#1181](https://github.com/spf13/hugo/issues/1181)
35 - Hugo is now built with `Go 1.5` which, among many other improvements, have fixed the last known data race in Hugo. [#917](https://github.com/spf13/hugo/issues/917)
36 - Paginator now also supports page groups. [#1274](https://github.com/spf13/hugo/issues/1274)
37 - Markdown improvements:

39 - Several new Blackfriday options are added:

49 - `hugo gen` can now generate man files, bash auto complete and markdown documentation
50 - Hugo will now make suggestions when a command is mistyped

86 ## Notices
87 - `hugo server` will watch by default now.
88 - 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:
89 - `getJson` to `getJSON`, `getCsv` to `getCSV`, `safeHtml` to
90 `safeHTML`, `safeCss` to `safeCSS`, `safeUrl` to `safeURL`, `Url` to `URL`,
91 `UrlPath` to `URLPath`, `BaseUrl` to `BaseURL`, `Recent` to `Pages`.

93 ## Known Issues
94
95 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 @tpng. If you encounter this bug, you may either compile Hugo v0.16-DEV from source, or use the following solution/workaround:
96 - **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 #1621 and #1628).
97 - **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 #1716).
