+**Hugo 0.56.0** is filled with improvements, but there are two main headliners: **Hugo Modules** and **Hugo Deploy**.  
+
+**Hugo Deploy** is implemented by [@vangent](https://github.com/vangent) and brings built-in deployment support for GCS, S3, or Azure using the Hugo CLI. See the [Hugo Deploy Documentation](https://gohugo.io/hosting-and-deployment/hugo-deploy/) for more information.
+
+**Hugo Modules** is very much a community effort on the design and specification side, but [@bep](https://github.com/bep) has driven the implementation. Some notes about what all of this is about:
+
+* A new `module` configuration section where you can import almost anything. You can configure both your own file mounts and the file mounts of the modules you import. This is the new recommended way of configuring what you earlier put in `configDir`, `staticDir` etc. And it also allows you to mount folders in non-Hugo-projects, e.g. the `SCSS` folder in the Bootstrap GitHub project.
+* A module consists of a set of mounts to the standard 7 component types in Hugo: `static`, `content`, `layouts`, `data`, `assets`, `i18n`, and `archetypes`. Yes, Theme Components can now include content, which should be very useful, especially in bigger multilingual projects.
+* Modules not in your local file cache will be downloaded automatically and even "hot replaced" while the server is running.
+* Hugo Modules supports and encourages semver versioned modules, and uses the minimal version selection algorithm to resolve versions.
+* A new set of CLI commands are provided to manage all of this: `hugo mod init`,  `hugo mod get`,  `hugo mod graph`,  `hugo mod tidy`, and  `hugo mod vendor`.
+
+**Hugo Modules is powered by Go Modules.**
+
+This is all very much brand new and there are only a few example projects around:
+
+* https://github.com/bep/docuapi is a theme that has been ported to **Hugo Modules** while testing this feature. It is a good example of a non-Hugo-project mounted into Hugo's folder structure. It even shows a JS Bundler implementation in regular Go templates.
+* https://github.com/bep/my-modular-site is a very simple site used for testing.
+
+See the [Hugo Modules Documentation](https://gohugo.io/hugo-modules/) for more information.

 This release represents **104 contributions by 19 contributors** to the main Hugo code base.
 [@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@vangent](https://github.com/vangent), [@niklasfasching](https://github.com/niklasfasching), and [@coliff](https://github.com/coliff) for their ongoing contributions.
 And a big thanks to [@digitalcraftsman](https://github.com/digitalcraftsman) and [@onedrawingperday](https://github.com/onedrawingperday) for their relentless work on keeping the themes site in pristine condition and to [@kaushalmodi](https://github.com/kaushalmodi) for his great work on the documentation site.

 ## Notes
 
-* Replace deprecated .GetParam usage [27a8049d](https://github.com/gohugoio/hugo/commit/27a8049da7996b703d02083182b84a002eae2599) [@bep](https://github.com/bep) [#5834](https://github.com/gohugoio/hugo/issues/5834)
+* We  have removed the "auto theme namespacing" of  params from theme configuration. This was an undocumented and hidden feature that wasn't useful in practice.
+* We have revised and improved the symlinks support in Hugo: In earlier versions, symlinks were only fully supported for the content folders. With the introduction of the new very flexible file mounts, with content support even for what we have traditionally named "themes", we needed a more precise definition of symlink support in Hugo:
+
+  * Symlinks are not supported outside of the main project ((the project you run `hugo` or `hugo server` from).
+  * In the main project `static` mounts, only symlinks to files are supported.
+  * In all other mounts in the main project, both file and directory symlinks are allowed.
