Upgrading to Dapr 0.4.0
If you're upgrading from an older version of Dapr to 0.4.0, follow the steps here to ensure a smooth upgrade. You know, the one where you don't get red errors on the terminal.. we all hate that, right?
Local Machine / Self-hosted
Uninstall Dapr using the CLI you currently have:
dapr uninstall --all
Next, get the latest CLI following these instructions, or alternatively download the latest and greatest release from here and put the dapr binary in your PATH.
Once you have downloaded the CLI, run:
dapr init
Wait for the update to finish, and you're good to go!
Kubernetes
Download the latest CLI release as outlined above in the Local Machine / Self-hosted section.
If you previously installed Dapr on your Kubernetes cluster using the Dapr CLI, run:
dapr uninstall --kubernetes
It's fine to ignore any errors that might show up.
If you previously installed Dapr using Helm 2.X:
helm del --purge dapr
If you previously installed Dapr using Helm 3.X:
helm uninstall dapr
Wait until Dapr is uninstalled, and make sure the dapr-system namespace is gone.
You can now follow these instructions on how to install Dapr using Helm 3.
Alternatively, if you want to install Dapr in a dev/test setup, run:
dapr init --kubernetes

Breaking Changes
With the introduction of multiple state stores, the API has changed to allow a developer to specify which state store the operation is targeting.
Starting this release, any state operation is required to provide a state store name:
v1.0/state/<state-store-name>/
For the latest API spec, go to this link.
Example
A call to get state prior to 0.4.0:
curl http://localhost:3500/v1.0/state/myKey
A call to get state in 0.4.0:
curl http://localhost:3500/v1.0/state/cassandra-dev/myKey
