+- The fission team is on http://slack.fission.io if you have any questions.
+
+### 0.4.0
+
+- This release is compatible with Kubernetes 1.7 onwards. 
+- We switched from ThirdPartyResources to CustomResourceDefinitions. ThirdPartyResources are removed in Kubernetes 1.8, so upgrade with caution, using the upgrade guide below.
+- Upgrade guides:
+  - [Upgrade guide from 0.3.0](../upgrade/upgrade-from-v0.3)
+  - To upgrade from 0.2.1, please upgrade to 0.3.0 first, following the upgrade guide in the 0.3.0 release.
+
+### 0.3.0
+
+Note: This release is incompatible with Kubernetes 1.8 (Because it uses ThirdPartyResources; see #314)
+
+This release introduces:
+
+- Build pipeline. Currently, only the Python environment supports this.
+- Workflow engine support (compatible with fission-workflows 0.1.1)
+
+### v0.2.1
+
+Lots of big changes in this release!
+
+- Most importantly, the API has changed a lot. We switched to Kubernetes
+ThirdPartyResources, and improved various pieces of the API to support
+new environments.
+
+- The old API was too different from widely used Kubernetes patterns,
+and so we decided to fully break compatibility for this release. We're still in
+alpha, so you should expect the occasional API breakage; we'll be
+better at preserving compatibility once we reach beta.
+
+- The CLI is still compatible. Environments are also still compatible --
+environment images that worked before continue to work.
+
+- We're creating an upgrade tool to help migrate; if you're upgrading
+v0.1.0 and can't do a fresh install, wait for the upgrade tool.
+
+- We now use Helm for installation instead of a set of YAML files.
+
+- The Fission "controller" is now stateless. Fission's etcd deployment
+is removed, since Fission stores state in ThirdPartyResources. Large
+function files are stored in a new function storage service, which
+uses a persistent volume.
+
+- And, we've started a new docs site; for now it's just the installation
+and upgrade guides, but we'll be writing more docs soon.
