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

## 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 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. [GH-1096]
* **New config function: `replace`** - Search and replace string values.
Search can be a regular expression. See documentation for more
info. [GH-1029]
* **New config function: `split`** - Split a value based on a delimiter.
This is useful for faking lists as parameters to modules.
* **New resource: `digitalocean_ssh_key`** [GH-1074]
* config: Expand `~` with homedir in `file()` paths [GH-1338]
* core: The serial of the state is only updated if there is an actual
change. This will lower the amount of state changing on things
like refresh.
* core: Autoload `terraform.tfvars.json` as well as `terraform.tfvars` [GH-1030]
* core: `.tf` files that start with a period are now ignored. [GH-1227]

automatically done initially.
* providers/google: Add `size` option to disk blocks for instances. [GH-1284]
* providers/aws: Improve support for tagging resources.
* providers/aws: Add a short syntax for Route 53 Record names, e.g.
`www` instead of `www.example.com`.
* providers/aws: Improve dependency violation error handling, when deleting
Internet Gateways or Auto Scaling groups [GH-1325].
* provider/aws: Add non-destructive updates to AWS RDS. You can now upgrade
`engine_version`, `parameter_group_name`, and `multi_az` without forcing
a new database to be created.[GH-1341]
* providers/aws: Full support for block device mappings on instances and
launch configurations [GH-1045, GH-1364]
* provisioners/remote-exec: SSH agent support. [GH-1208]
BUG FIXES:
* core: module outputs can be used as inputs to other modules [GH-822]
* core: Self-referencing splat variables are no longer allowed in
provisioners. [GH-795][GH-868]
* core: Validate that `depends_on` doesn't contain interpolations. [GH-1015]

* core: Fix invalid plan that resulted in "diffs don't match" error when
a computed attribute was used as part of a set parameter. [GH-1073]
* core: Fix edge case where state containing both "resource" and
"resource.0" would ignore the latter completely. [GH-1086]
* core: Modules with a source of a relative file path moving up
directories work properly, i.e. "../a" [GH-1232]
* providers/aws: manually deleted VPC removes it from the state
* providers/aws: `source_dest_check` regression fixed (now works). [GH-1020]
* providers/aws: Longer wait times for DB instances.
* providers/aws: Longer wait times for route53 records (30 mins). [GH-1164]
* providers/aws: Fix support for TXT records in Route 53. [GH-1213]
* providers/aws: Fix support for wildcard records in Route 53. [GH-1222]
* providers/aws: Fix issue with ignoring the 'self' attribute of a
Security Group rule. [GH-1223]
* providers/aws: Fix issue with `sql_mode` in RDS parameter group always
causing an update. [GH-1225]
* providers/aws: Fix dependency violation with subnets and security groups
[GH-1252]
* providers/aws: Fix issue with refreshing `db_subnet_groups` causing an error
instead of updating state [GH-1254]
* providers/aws: Prevent empty string to be used as default
`health_check_type` [GH-1052]
* providers/aws: Add tags on AWS IG creation, not just on update [GH-1176]
* providers/digitalocean: Waits until droplet is ready to be destroyed [GH-1057]
* providers/digitalocean: More lenient about 404's while waiting [GH-1062]
* providers/digitalocean: FQDN for domain records in CNAME, MX, NS, etc.
Also fixes invalid updates in plans. [GH-863]

* providers/heroku: Fix panic when config vars block was empty. [GH-1211]
PLUGIN CHANGES:
* New `helper/schema` fields for resources: `Deprecated` and `Removed` allow
plugins to generate warning or error messages when a given attribute is used.
## 0.3.7 (February 19, 2015)

`final_snapshot_identifier` and `skip_final_snapshot`; the presence or
absence of the former now implies the latter. [GH-874]
* provider/aws: Avoid unnecessary update of `aws_subnet` when
`map_public_ip_on_launch` is not specified in config. [GH-898]

managed. [GH-968]
* provider/aws: Fix case where route table would delete its routes
on an unrelated change. [GH-990]
* provider/google: Fix bug preventing instances with metadata from being
created [GH-884].
PLUGIN CHANGES:
* New `helper/schema` type: `TypeFloat` [GH-594]
* New `helper/schema` field for resources: `Exists` must point to a function
to check for the existence of a resource. This is used to properly
handle the case where the resource was manually deleted. [GH-766]
* There is a semantic change in `GetOk` where it will return `true` if
there is any value in the diff that is _non-zero_. Before, it would
return true only if there was a value in the diff.

if there is a dependency violation since it is probably just eventual
consistency. [GH-436]

## 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).

destroys dependencies. [GH-357]
* providers/aws: More robust destroy for route53 records. [GH-342]
* providers/aws: ELB generates much more correct plans without extranneous
data.
* providers/aws: ELB works properly with dynamically changing
count of instances.
* providers/aws: Terraform can handle ELBs deleted manually. [GH-304]
* providers/aws: Report errors properly if RDS fails to delete. [GH-310]

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).

IMPROVEMENTS:
* core: Plugins are automatically discovered in the executable directory
or pwd if named properly. [GH-190]

## 0.2.0 (August 28, 2014)
BACKWARDS INCOMPATIBILITIES:

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:

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]

* 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.
