+## 0.4.0 (April 2, 2015)
 
 BACKWARDS INCOMPATIBILITIES:
 
   * Commands `terraform push` and `terraform pull` are now nested under
     the `remote` command: `terraform remote push` and `terraform remote pull`.
     The old `remote` functionality is now at `terraform remote config`. This
     consolidates all remote state management under one command.
+  * Period-prefixed configuration files are now ignored. This might break
+    existing Terraform configurations if you had period-prefixed files.
+  * The `block_device` attribute of `aws_instance` has been removed in favor
+    of three more specific attributes to specify block device mappings:
+    `root_block_device`, `ebs_block_device`, and `ephemeral_block_device`.
+    Configurations using the old attribute will generate a validation error
+    indicating that they must be updated to use the new fields [GH-1045].
 
 FEATURES:
 
   * **New provider: `dme` (DNSMadeEasy)** [GH-855]
+  * **New provider: `docker` (Docker)** - Manage container lifecycle
+      using the standard Docker API. [GH-855]
+  * **New provider: `openstack` (OpenStack)** - Interact with the many resources
+      provided by OpenStack. [GH-924]
+  * **New feature: `terraform_remote_state` resource** - Reference remote
+      states from other Terraform runs to use Terraform outputs as inputs
+      into another Terraform run.
   * **New command: `taint`** - Manually mark a resource as tainted, causing
       a destroy and recreate on the next plan/apply.
+  * **New resource: `aws_vpn_gateway`** [GH-1137]
+  * **New resource: `aws_elastic_network_interfaces`** [GH-1149]
   * **Self-variables** can be used to reference the current resource's
       attributes within a provisioner. Ex. `${self.private_ip_address}` [GH-1033]

+  * **Continuous state** saving during `terraform apply`. The state file is
+      continuously updated as apply is running, meaning that the state is
       less likely to become corrupt in a catastrophic case: terraform panic
       or system killing Terraform.
   * **Math operations** in interpolations. You can now do things like
       `${count.index+1}`. [GH-1068]
+  * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go),
+      a fork of the offical `awslabs` repo. We forked for stability while
+      `awslabs` refactored the library, and will move back to the officially
