 Helm is a tool for managing Kubernetes charts. Charts are packages of
 pre-configured Kubernetes resources.
 
+Features:
+
+- Helm now has both a client (`helm`) and a server (`tiller`). The
+  server runs inside of Kubernetes, and manages your resources.
+- Helm's chart format has changed for the better:
+  - Dependencies are immutable and stored inside of a chart's `charts/`
+    directory.
+  - Charts are strongly versioned using SemVer 2
+  - Charts can be loaded from directories or from chart archive files
+  - Helm supports Go templates without requiring you to run `generate`
+    or `template` commands.
+  - Helm makes it easy to configure your releases -- and share the
+    configuration with the rest of your team.
+- Helm chart repositories now use plain HTTP instead of Git/GitHub.
+  There is no longer any GitHub dependency.
+  - A chart server is a simple HTTP server
+  - Charts are referenced by version
+  - The `helm serve` command will run a local chart server, though you
+    can easily use object storage (S3, GCS) or a regular web server.
+  - And you can still load charts from a local directory.
+- The Helm workspace is gone. You can now work anywhere on your
+  filesystem that you want to work.
