## 0.3.0 (October 14, 2014)

FEATURES:

  * **Modules**: Configuration can now be modularized. Modules can live on
    GitHub, BitBucket, Git/Hg repos, HTTP URLs, and file paths. Terraform
    automatically downloads/updates modules for you on request.
  * **New Command: `init`**. This command initializes a Terraform configuration
    from an existing Terraform module (also new in 0.3).
  * **New Command: `destroy`**. This command destroys infrastructure
    created with `apply`.
  * Terraform will ask for user input to fill in required variables and
    provider configurations if they aren't set.
  * `terraform apply MODULE` can be used as a shorthand to quickly build
    infrastructure from a module.
  * The state file format is now JSON rather than binary. This allows for
    easier machine and human read/write. Old binary state files will be
    automatically upgraded.
  * You can now specify `create_before_destroy` as an option for replacement
    so that new resources are created before the old ones are destroyed.
  * The `count` metaparameter can now contain interpolations (such as
    variables).
  * The current index for a resource with a `count` set can be interpolated
    using `${count.index}`.
  * Various paths can be interpolated with the `path.X` variables. For example,
    the path to the current module can be interpolated using `${path.module}`.

IMPROVEMENTS:

  * config: Trailing commas are now allowed for the final elements of lists.
  * core: Plugins are loaded from `~/.terraform.d/plugins` (Unix) or
    `%USERDATA%/terraform.d/plugins` (Windows).

      data.
  * providers/aws: ELB works properly with dynamically changing

      detect it isn't attached. [GH-276]
  * providers/digitalocean: Handle situations when resource was destroyed
      manually. [GH-279]
  * providers/digitalocean: Fix a couple scenarios where the diff was
      incorrect (and therefore the execution as well).

## 0.2.0 (August 28, 2014)

BACKWARDS INCOMPATIBILITIES:

  * We've replaced the configuration language in use from a C library to
    a pure-Go reimplementation. In the process, we removed some features
    of the language since it was too flexible:
    * Semicolons are no longer valid at the end of lines
    * Keys cannot be double-quoted strings: `"foo" = "bar"` is no longer
      valid.
    * JSON style maps `{ "foo": "bar" }` are no longer valid outside of JSON.
      Maps must be in the format of `{ foo = "bar" }` (like other objects
      in the config)
  * Heroku apps now require (will not validate without) `region` and
    `name` due to an upstream API change. [GH-239]

FEATURES:

  * **New Provider: `google`**: Manage Google Compute instances, disks,
      firewalls, and more.
  * **New Provider: `mailgun`**: Manage mailgun domains.
  * **New Function: `concat`**: Concatenate multiple strings together.
    Example: `concat(var.region, "-", var.channel)`.

IMPROVEMENTS:

  * core: "~/.terraformrc" (Unix) or "%APPDATA%/terraform.rc" (Windows)
    can be used to configure custom providers and provisioners. [GH-192]
  * providers/aws: EIPs now expose `allocation_id` and `public_ip`
      attributes.
  * providers/aws: Security group rules can be updated without a
      destroy/create.
  * providers/aws: You can enable and disable dns settings for VPCs. [GH-172]
  * providers/aws: Can specify a private IP address for `aws_instance` [GH-217]

BUG FIXES:

  * core: Variables are validated to not contain interpolations. [GH-180]
  * core: Key files for provisioning can now contain `~` and will be expanded
      to the user's home directory. [GH-179]
  * core: The `file()` function can load files in sub-directories. [GH-213]
  * core: Fix issue where some JSON structures didn't map properly into
     Terraform structures. [GH-177]
  * core: Resources with only `file()` calls will interpolate. [GH-159]
  * core: Variables work in block names. [GH-234]
  * core: Plugins are searched for in the same directory as the executable
      before the PATH. [GH-157]
  * command/apply: "tfvars" file no longer interferes with plan apply. [GH-153]
  * providers/aws: Fix issues around failing to read EIPs. [GH-122]
  * providers/aws: Autoscaling groups now register and export load
    balancers. [GH-207]
  * providers/aws: Ingress results are treated as a set, so order doesn't
      matter anymore. [GH-87]
  * providers/aws: Instance security groups treated as a set [GH-194]
  * providers/aws: Retry Route53 requests if operation failed because another
      operation is in progress [GH-183]
  * providers/aws: Route53 records with multiple record values work. [GH-221]
  * providers/aws: Changing AMI doesn't result in errors anymore. [GH-196]
  * providers/heroku: If you delete the `config_vars` block, config vars
      are properly nuked.
  * providers/heroku: Domains and drains are deleted before the app.
  * providers/heroku: Moved from the client library bgentry/heroku-go to
      cyberdelia/heroku-go [GH-239].
  * providers/heroku: Plans without a specific plan name for
      heroku\_addon work. [GH-198]

PLUGIN CHANGES:

  * **New Package:** `helper/schema`. This introduces a high-level framework
    for easily writing new providers and resources. The Heroku provider has
    been converted to this as an example.
