## 0.7.0 (August 2, 2016)

BACKWARDS INCOMPATIBILITIES / NOTES:

  * Terraform Core
   * Terraform's built-in plugins are now distributed as part of the main Terraform binary, and use the go-plugin framework. Overrides are still available using separate binaries, but will need recompiling against Terraform 0.7.
   * The `terraform plan` command no longer persists state. This makes the command much safer to run, since it is now side-effect free. The `refresh` and `apply` commands still persist state to local and remote storage. Any automation that assumes that `terraform plan` persists state will need to be reworked to explicitly call `terraform refresh` to get the equivalent side-effect. (The `terraform plan` command no longer has the `-state-out` or `-backup` flags due to this change.)
   * The `concat()` interpolation function can no longer be used to join strings.
   * Quotation marks may no longer be escaped in HIL expressions ([#7201](https://github.com/hashicorp/terraform/issues/7201))
   * Lists materialized using splat syntax, for example `aws_instance.foo.*.id` are now ordered by the count index rather than lexographically sorted. If this produces a large number of undesirable differences, you can use the new `sort()` interpolation function to produce the previous behaviour.
   * You now access the values of maps using the syntax `var.map["key"]` or the `lookup` function instead of `var.map.key`.
   * Outputs on `terraform_remote_state` resources are now top level attributes rather than inside the `output` map. In order to access outputs, use the syntax: `terraform_remote_state.name.outputname`. Currently outputs cannot be named `config` or `backend`.
  * AWS Provider
   * `aws_elb` now defaults `cross_zone_load_balancing` to `true`
   * `aws_instance`: EC2 Classic users may continue to use `security_groups` to reference Security Groups by their `name`. Users who are managing Instances inside VPCs will need to use `vpc_security_group_ids` instead, and reference the security groups by their `id`. Ref https://github.com/hashicorp/terraform/issues/6416#issuecomment-219145065
   * `aws_kinesis_firehose_delivery_stream`: AWS Kinesis Firehose has been refactored to support Redshift as a destination in addition to S3. As a result, the configuration has changed and users will need to update their configuration to match the new `s3_configuration` block. Checkout the documentaiton on [AWS Kinesis Firehose](http://localhost:4567/docs/providers/aws/r/kinesis_firehose_delivery_stream.html) for more information ([#7375](https://github.com/hashicorp/terraform/issues/7375))
   * `aws_route53_record`: `latency_routing_policy`, `geolocation_routing_policy`, and `failover_routing_policy` block options have been added. With these additions we’ve renamed the `weight` attribute to `weighted_routing_policy`, and it has changed from a string to a block to match the others. Please see the updated documentation on using `weighted_routing_policy`:  https://www.terraform.io/docs/providers/aws/r/route53_record.html . ([#6954](https://github.com/hashicorp/terraform/issues/6954))
   * `aws_db_instance` now defaults `publicly_accessible` to false
  * Microsoft Azure Provider
   * In documentation, the "Azure (Resource Manager)" provider has been renamed to the "Microsoft Azure" provider.
   * `azurerm_dns_cname_record` now accepts a single record rather than a list of records
   * `azurerm_virtual_machine` computer_name now Required
  * Openstack Provider
   * `openstack_networking_subnet_v2` now defaults to turning DHCP on.
   * `openstack_fw_policy_v1` now correctly applies rules in the order they are specified. Upon the next apply, current rules might be re-ordered.
   * The `member` attribute of `openstack_lb_pool_v1` has been deprecated. Please ue the new `openstack_lb_member_v1` resource.
  * Docker Provider
   * `keep_updated` parameter removed from `docker_image` - This parameter never did what it was supposed to do.  See relevant docs, specifically `pull_trigger` & new `docker_registry_image` data source to understand how to keep your `docker_image` updated.
  * Atlas Provider
   * `atlas_artifact` resource has be deprecated. Please use the new `atlas_artifact` Data Source.
  * CloudStack Provider
   * All deprecated parameters are removed from all `CloudStack` resources

BACKWARDS INCOMPATIBILITIES / NOTES:
 * `aws_instance` - if you still use `security_groups` field for SG IDs - i.e. inside VPC, this will generate diffs during `plan` and `apply` will **recreate** the resource. Terraform expects IDs (VPC SGs) inside `vpc_security_group_ids`.

## 0.6.10 (January 27, 2016)

BACKWARDS INCOMPATIBILITIES / NOTES:

  * The `-module-depth` flag available on `plan`, `apply`, `show`, and `graph` now defaults to `-1`, causing
    resources within modules to be expanded in command output. This is only a cosmetic change; it does not affect
    any behavior.
  * This release includes a bugfix for `$${}` interpolation escaping. These strings are now properly converted to `${}`
    during interpolation. This may cause diffs on existing configurations in certain cases.
  * Users of `consul_keys` should note that the `value` sub-attribute of `key` will no longer be updated with the remote value of the key. It should be only used to _set_ a key in Consul K/V. To reference key values, use the `var` attribute.
  * The 0.6.9 release contained a regression in `aws_autoscaling_group` capacity waiting behavior for configs where `min_elb_capacity != desired_capacity` or `min_size != desired_capacity`. This release remedies that regression by un-deprecating `min_elb_capacity` and restoring the prior behavior.
  * Users of `aws_security_group` may notice new diffs in initial plans with 0.6.10 due to a bugfix that fixes drift detection on nested security group rules. These new diffs should reflect the actual state of the resources, which Terraform previously was unable to see.

BACKWARDS INCOMPATIBILITIES:

 * command/push: If a variable is already set within Atlas, it won't be

 * connection/ssh: The `agent` field now defaults to `true` if
     the `SSH_AGENT_SOCK` environment variable is present. In other words,
     `ssh-agent` support is now opt-out instead of opt-in functionality. ([#2408](https://github.com/hashicorp/terraform/issues/2408))

     will load from other sources.
 * `concat()` has been repurposed to combine lists instead of strings (old behavior
     of joining strings is maintained in this version but is deprecated, strings
     should be combined using interpolation syntax, like "${var.foo}{var.bar}")

## 0.5.0 (May 7, 2015)

BACKWARDS INCOMPATIBILITIES:

  * provider/aws: Terraform now remove the default egress rule created by AWS in
    a new security group.

FEATURES:

     provider can be configured so resources can apply to different settings.
     As an example, this allows Terraform to manage multiple regions with AWS.
  * **Environmental variables to set variables**: Environment variables can be
     used to set variables. The environment variables must be in the format
     `TF_VAR_name` and this will be checked last for a value.
  * **New remote state backend: `s3`**: You can now store remote state in
     an S3 bucket. ([#1723](https://github.com/hashicorp/terraform/issues/1723))
  * **Automatic AWS retries**: This release includes a lot of improvement
     around automatic retries of transient errors in AWS. The number of
     retry attempts is also configurable.

      systems so copying your ".terraform" folder works. ([#1418](https://github.com/hashicorp/terraform/issues/1418))
  * core: don't validate providers too early when nested in a module ([#1380](https://github.com/hashicorp/terraform/issues/1380))

  * provider/aws: Fix issue with `aws_launch_configuration` causing an
      unnecessary diff for pre-0.4 environments ([#1371](https://github.com/hashicorp/terraform/issues/1371))

## 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 ([#1045](https://github.com/hashicorp/terraform/issues/1045)).

FEATURES:

  * **New provider: `dme` (DNSMadeEasy)** ([#855](https://github.com/hashicorp/terraform/issues/855))
  * **New provider: `docker` (Docker)** - Manage container lifecycle
      using the standard Docker API. ([#855](https://github.com/hashicorp/terraform/issues/855))
  * **New provider: `openstack` (OpenStack)** - Interact with the many resources
      provided by OpenStack. ([#924](https://github.com/hashicorp/terraform/issues/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`** ([#1137](https://github.com/hashicorp/terraform/issues/1137))
  * **New resource: `aws_elastic_network_interfaces`** ([#1149](https://github.com/hashicorp/terraform/issues/1149))
  * **Self-variables** can be used to reference the current resource's
      attributes within a provisioner. Ex. `${self.private_ip_address}` ([#1033](https://github.com/hashicorp/terraform/issues/1033))
  * **Continuous state** saving during `terraform apply`. The state file is
      continuously updated as apply is running, meaning that the state is
      less likely to become corrupt in a catastrophic case: terraform panic
      or system killing Terraform.
  * **Math operations** in interpolations. You can now do things like
      `${count.index + 1}`. ([#1068](https://github.com/hashicorp/terraform/issues/1068))
  * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go),
      a fork of the official `awslabs` repo. We forked for stability while
      `awslabs` refactored the library, and will move back to the officially
      supported version in the next release.

IMPROVEMENTS:

  * **New config function: `format`** - Format a string using `sprintf`
      format. ([#1096](https://github.com/hashicorp/terraform/issues/1096))

## 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`.

## 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. ([#239](https://github.com/hashicorp/terraform/issues/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. ([#192](https://github.com/hashicorp/terraform/issues/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. ([#172](https://github.com/hashicorp/terraform/issues/172))
  * providers/aws: Can specify a private IP address for `aws_instance` ([#217](https://github.com/hashicorp/terraform/issues/217))

BUG FIXES:

  * core: Variables are validated to not contain interpolations. ([#180](https://github.com/hashicorp/terraform/issues/180))
  * core: Key files for provisioning can now contain `~` and will be expanded
      to the user's home directory. ([#179](https://github.com/hashicorp/terraform/issues/179))
  * core: The `file()` function can load files in sub-directories. ([#213](https://github.com/hashicorp/terraform/issues/213))

  * providers/aws: Fix issues around failing to read EIPs. ([#122](https://github.com/hashicorp/terraform/issues/122))
  * providers/aws: Autoscaling groups now register and export load
    balancers. ([#207](https://github.com/hashicorp/terraform/issues/207))
  * providers/aws: Ingress results are treated as a set, so order doesn't
      matter anymore. ([#87](https://github.com/hashicorp/terraform/issues/87))
  * providers/aws: Instance security groups treated as a set ([#194](https://github.com/hashicorp/terraform/issues/194))
