   627  
   628  ## 0.5.0 (May 7, 2015)
   629  
   630  BACKWARDS INCOMPATIBILITIES:
   631  
   632    * provider/aws: Terraform now remove the default egress rule created by AWS in
   633      a new security group.
   634  
   635  FEATURES:
   636  
   637    * **Multi-provider (a.k.a multi-region)**: Multiple instances of a single
   638       provider can be configured so resources can apply to different settings.
   639       As an example, this allows Terraform to manage multiple regions with AWS.
   640    * **Environmental variables to set variables**: Environment variables can be
   641       used to set variables. The environment variables must be in the format
   642       `TF_VAR_name` and this will be checked last for a value.

   678    * **New resource: `google_dns_managed_zone`**
   679    * **New resource: `google_dns_record_set`**
   680    * **Migrate to upstream AWS SDK:** Migrate the AWS provider to
   681        [awslabs/aws-sdk-go](https://github.com/awslabs/aws-sdk-go),
   682        the official `awslabs` library. Previously we had forked the library for
   683        stability while `awslabs` refactored. Now that work has completed, and we've
   684        migrated back to the upstream version.

   737    * core: avoid unnecessary cycles by pruning tainted destroys from
   738        graph if there are no tainted resources [GH-1475]
   739    * core: fix issue where destroy nodes weren't pruned in specific
   740        edge cases around matching prefixes, which could cause cycles [GH-1527]
   741    * core: fix issue causing diff mismatch errors in certain scenarios during
   742        resource replacement [GH-1515]

   797        without forcing a new resource  [GH-1382]
   798  
   799  BUG FIXES:
   800  
   801    * core: module paths in ".terraform" are consistent across different

   828  ## 0.4.0 (April 2, 2015)
   829  
   830  BACKWARDS INCOMPATIBILITIES:
   831  
   832    * Commands `terraform push` and `terraform pull` are now nested under
   833      the `remote` command: `terraform remote push` and `terraform remote pull`.
   834      The old `remote` functionality is now at `terraform remote config`. This
   835      consolidates all remote state management under one command.
   836    * Period-prefixed configuration files are now ignored. This might break
   837      existing Terraform configurations if you had period-prefixed files.
   838    * The `block_device` attribute of `aws_instance` has been removed in favor
   839      of three more specific attributes to specify block device mappings:
   840      `root_block_device`, `ebs_block_device`, and `ephemeral_block_device`.
   841      Configurations using the old attribute will generate a validation error
   842      indicating that they must be updated to use the new fields [GH-1045].

   854    * **New command: `taint`** - Manually mark a resource as tainted, causing
   855        a destroy and recreate on the next plan/apply.
   856    * **New resource: `aws_vpn_gateway`** [GH-1137]
   857    * **New resource: `aws_elastic_network_interfaces`** [GH-1149]

   859        attributes within a provisioner. Ex. `${self.private_ip_address}` [GH-1033]
   860    * **Continuous state** saving during `terraform apply`. The state file is
   861        continuously updated as apply is running, meaning that the state is
   862        less likely to become corrupt in a catastrophic case: terraform panic
   863        or system killing Terraform.
   864    * **Math operations** in interpolations. You can now do things like
   865        `${count.index + 1}`. [GH-1068]
   866    * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go),
   867        a fork of the official `awslabs` repo. We forked for stability while
   868        `awslabs` refactored the library, and will move back to the officially
   869        supported version in the next release.
   870  
   871  IMPROVEMENTS:
   872  
   873    * **New config function: `format`** - Format a string using `sprintf`
   874        format. [GH-1096]
   875    * **New config function: `replace`** - Search and replace string values.
   876        Search can be a regular expression. See documentation for more
   877        info. [GH-1029]
   878    * **New config function: `split`** - Split a value based on a delimiter.
   879        This is useful for faking lists as parameters to modules.
   880    * **New resource: `digitalocean_ssh_key`** [GH-1074]
   881    * config: Expand `~` with homedir in `file()` paths [GH-1338]
   882    * core: The serial of the state is only updated if there is an actual
   883        change. This will lower the amount of state changing on things
   884        like refresh.
   885    * core: Autoload `terraform.tfvars.json` as well as `terraform.tfvars` [GH-1030]
   886    * core: `.tf` files that start with a period are now ignored. [GH-1227]
   887    * command/remote-config: After enabling remote state, a `pull` is
   888        automatically done initially.
   889    * providers/google: Add `size` option to disk blocks for instances. [GH-1284]
   890    * providers/aws: Improve support for tagging resources.
   891    * providers/aws: Add a short syntax for Route 53 Record names, e.g.
   892        `www` instead of `www.example.com`.
   893    * providers/aws: Improve dependency violation error handling, when deleting
   894        Internet Gateways or Auto Scaling groups [GH-1325].
   895    * provider/aws: Add non-destructive updates to AWS RDS. You can now upgrade
   896        `engine_version`, `parameter_group_name`, and `multi_az` without forcing
   897        a new database to be created.[GH-1341]
   898    * providers/aws: Full support for block device mappings on instances and
   899        launch configurations [GH-1045, GH-1364]
   900    * provisioners/remote-exec: SSH agent support. [GH-1208]
   901  
   902  BUG FIXES:
   903  
   904    * core: module outputs can be used as inputs to other modules [GH-822]
   905    * core: Self-referencing splat variables are no longer allowed in
   906        provisioners. [GH-795][GH-868]
   907    * core: Validate that `depends_on` doesn't contain interpolations. [GH-1015]
   908    * core: Module inputs can be non-strings. [GH-819]
   909    * core: Fix invalid plan that resulted in "diffs don't match" error when
   910        a computed attribute was used as part of a set parameter. [GH-1073]
   911    * core: Fix edge case where state containing both "resource" and
   912        "resource.0" would ignore the latter completely. [GH-1086]
   913    * core: Modules with a source of a relative file path moving up
   914        directories work properly, i.e. "../a" [GH-1232]
   915    * providers/aws: manually deleted VPC removes it from the state
   916    * providers/aws: `source_dest_check` regression fixed (now works). [GH-1020]
   917    * providers/aws: Longer wait times for DB instances.
   918    * providers/aws: Longer wait times for route53 records (30 mins). [GH-1164]
   919    * providers/aws: Fix support for TXT records in Route 53. [GH-1213]
   920    * providers/aws: Fix support for wildcard records in Route 53. [GH-1222]
   921    * providers/aws: Fix issue with ignoring the 'self' attribute of a
   922        Security Group rule. [GH-1223]
   923    * providers/aws: Fix issue with `sql_mode` in RDS parameter group always
   924        causing an update. [GH-1225]
   925    * providers/aws: Fix dependency violation with subnets and security groups
   926        [GH-1252]
   927    * providers/aws: Fix issue with refreshing `db_subnet_groups` causing an error
   928        instead of updating state [GH-1254]
   929    * providers/aws: Prevent empty string to be used as default
   930        `health_check_type` [GH-1052]
   931    * providers/aws: Add tags on AWS IG creation, not just on update [GH-1176]
   932    * providers/digitalocean: Waits until droplet is ready to be destroyed [GH-1057]
   933    * providers/digitalocean: More lenient about 404's while waiting [GH-1062]
   934    * providers/digitalocean: FQDN for domain records in CNAME, MX, NS, etc.
   935        Also fixes invalid updates in plans. [GH-863]
   936    * providers/google: Network data in state was not being stored. [GH-1095]
   937    * providers/heroku: Fix panic when config vars block was empty. [GH-1211]
   938  
   939  PLUGIN CHANGES:
   940  
   941    * New `helper/schema` fields for resources: `Deprecated` and `Removed` allow
   942        plugins to generate warning or error messages when a given attribute is used.
   943  
   944  ## 0.3.7 (February 19, 2015)
   945  
   946  IMPROVEMENTS:
   947  
   948    * **New resources: `google_compute_forwarding_rule`, `google_compute_http_health_check`,
   949        and `google_compute_target_pool`** - Together these provide network-level
   950        load balancing. [GH-588]
   951    * **New resource: `aws_main_route_table_association`** - Manage the main routing table
   952        of a VPC. [GH-918]

   954    * core: Formalized the syntax of interpolations and documented it
   955        very heavily.
   956    * core: Strings in interpolations can now contain further interpolations,
   957        e.g.: `foo ${bar("${baz}")}`.
   958    * provider/aws: Internet gateway supports tags [GH-720]
   959    * provider/aws: Support the more standard environmental variable names
   960        for access key and secret keys. [GH-851]
   961    * provider/aws: The `aws_db_instance` resource no longer requires both
   962        `final_snapshot_identifier` and `skip_final_snapshot`; the presence or
   963        absence of the former now implies the latter. [GH-874]
   964    * provider/aws: Avoid unnecessary update of `aws_subnet` when
   965        `map_public_ip_on_launch` is not specified in config. [GH-898]
   966    * provider/aws: Add `apply_method` to `aws_db_parameter_group` [GH-897]
   967    * provider/aws: Add `storage_type` to `aws_db_instance` [GH-896]
   968    * provider/aws: ELB can update listeners without requiring new. [GH-721]

   972    * provider/google: Remove "client secrets file", as it's no longer necessary
   973        for API authentication [GH-884].
   974    * provider/google: Expose `self_link` on `google_compute_instance` [GH-906]
   975  
   976  BUG FIXES:
   977

   981    * core: Escape characters `\"`, `\n`, and `\\` now work in interpolations.
   982    * core: Fix crash that could occur when there are exactly zero providers
   983        installed on a system. [GH-786]
   984    * core: JSON TF configurations can configure provisioners. [GH-807]
   985    * core: Sort `depends_on` in state to prevent unnecessary file changes. [GH-928]
   986    * core: State containing the zero value won't cause a diff with the
   987        lack of a value. [GH-952]
   988    * core: If a set type becomes empty, the state will be properly updated
   989        to remove it. [GH-952]
   990    * core: Bare "splat" variables are not allowed in provisioners. [GH-636]
   991    * core: Invalid configuration keys to sub-resources are now errors. [GH-740]
   992    * command/apply: Won't try to initialize modules in some cases when
   993        no arguments are given. [GH-780]
   994    * command/apply: Fix regression where user variables weren't asked [GH-736]
   995    * helper/hashcode: Update `hash.String()` to always return a positive index.
   996        Fixes issue where specific strings would convert to a negative index
   997        and be omitted when creating Route53 records. [GH-967]
   998    * provider/aws: Automatically suffix the Route53 zone name on record names. [GH-312]
   999    * provider/aws: Instance should ignore root EBS devices. [GH-877]
  1000    * provider/aws: Fix `aws_db_instance` to not recreate each time. [GH-874]
  1001    * provider/aws: ASG termination policies are synced with remote state. [GH-923]
  1002    * provider/aws: ASG launch configuration setting can now be updated in-place. [GH-904]

  1004    * provider/aws: Tags with empty values (empty string) are properly
  1005        managed. [GH-968]
  1006    * provider/aws: Fix case where route table would delete its routes
  1007        on an unrelated change. [GH-990]
  1008    * provider/google: Fix bug preventing instances with metadata from being
  1009        created [GH-884].
  1010  
  1011  PLUGIN CHANGES:
  1012  
  1013    * New `helper/schema` type: `TypeFloat` [GH-594]
  1014    * New `helper/schema` field for resources: `Exists` must point to a function
  1015        to check for the existence of a resource. This is used to properly
  1016        handle the case where the resource was manually deleted. [GH-766]
  1017    * There is a semantic change in `GetOk` where it will return `true` if
  1018        there is any value in the diff that is _non-zero_. Before, it would
  1019        return true only if there was a value in the diff.
  1020

  1038    * core: temporary/hidden files that look like Terraform configurations
  1039        are no longer loaded. [GH-548]
  1040    * core: Set types in resources now result in deterministic states,
  1041        resulting in cleaner plans. [GH-663]
  1042    * core: fix issue where "diff was not the same" would come up with
  1043        diffing lists. [GH-661]
  1044    * core: fix crash where module inputs weren't strings, and add more
  1045        validation around invalid types here. [GH-624]

  1054    * provider/aws: `availability_zones` on ELB will contain more than one
  1055        AZ if it is set as such. [GH-682]
  1056    * provider/aws: More fields are marked as "computed" properly, resulting
  1057        in more accurate diffs for AWS instances. [GH-712]
  1058    * provider/aws: Fix panic case by using the wrong type when setting
  1059        volume size for AWS instances. [GH-712]
  1060    * provider/aws: route table ignores routes with 'EnableVgwRoutePropagation'
  1061        origin since those come from gateways. [GH-722]

  1063        support for `aws_vpc`. [GH-704]
  1064    * provider/aws: Tags are not marked as computed. This introduces another
  1065        issue with not detecting external tags, but this will be fixed in
  1066        the future. [GH-730]

  1138    * core: Config validation will not error if the field is being
  1139        computed so the value is still unknown.
  1140    * core: If a resource fails to create and has provisioners, it is
  1141        marked as tainted. [GH-434]
  1142    * core: Set types are validated to be sets. [GH-413]
  1143    * core: String types are validated properly. [GH-460]

  1172  
  1173  FEATURES:
  1174  
  1175    * **Modules**: Configuration can now be modularized. Modules can live on

  1177      automatically downloads/updates modules for you on request.
  1178    * **New Command: `init`**. This command initializes a Terraform configuration
  1179      from an existing Terraform module (also new in 0.3).
  1180    * **New Command: `destroy`**. This command destroys infrastructure
  1181      created with `apply`.
  1182    * Terraform will ask for user input to fill in required variables and
  1183      provider configurations if they aren't set.
  1184    * `terraform apply MODULE` can be used as a shorthand to quickly build
  1185      infrastructure from a module.
  1186    * The state file format is now JSON rather than binary. This allows for
  1187      easier machine and human read/write. Old binary state files will be
  1188      automatically upgraded.
  1189    * You can now specify `create_before_destroy` as an option for replacement
  1190      so that new resources are created before the old ones are destroyed.
  1191    * The `count` metaparameter can now contain interpolations (such as
  1192      variables).
  1193    * The current index for a resource with a `count` set can be interpolated
  1194      using `${count.index}`.
  1195    * Various paths can be interpolated with the `path.X` variables. For example,
  1196      the path to the current module can be interpolated using `${path.module}`.

  1221    * providers/google: `google_compute_disk` supports `type` to support disks
  1222        such as SSDs. [GH-351]

  1240    * providers/aws: More robust destroy for route53 records. [GH-342]
  1241    * providers/aws: ELB generates much more correct plans without extranneous
  1242        data.
  1243    * providers/aws: ELB works properly with dynamically changing
  1244        count of instances.
  1245    * providers/aws: Terraform can handle ELBs deleted manually. [GH-304]

  1297  BACKWARDS INCOMPATIBILITIES:
  1298  
  1299    * We've replaced the configuration language in use from a C library to
  1300      a pure-Go reimplementation. In the process, we removed some features
  1301      of the language since it was too flexible:
  1302      * Semicolons are no longer valid at the end of lines
  1303      * Keys cannot be double-quoted strings: `"foo" = "bar"` is no longer
  1304        valid.
  1305      * JSON style maps `{ "foo": "bar" }` are no longer valid outside of JSON.
  1306        Maps must be in the format of `{ foo = "bar" }` (like other objects
  1307        in the config)
  1308    * Heroku apps now require (will not validate without) `region` and
  1309      `name` due to an upstream API change. [GH-239]

  1317      Example: `concat(var.region, "-", var.channel)`.
  1318  
  1319  IMPROVEMENTS:
  1320  
  1321    * core: "~/.terraformrc" (Unix) or "%APPDATA%/terraform.rc" (Windows)
  1322      can be used to configure custom providers and provisioners. [GH-192]
  1323    * providers/aws: EIPs now expose `allocation_id` and `public_ip`
  1324        attributes.

  1337       Terraform structures. [GH-177]
  1338    * core: Resources with only `file()` calls will interpolate. [GH-159]
  1339    * core: Variables work in block names. [GH-234]
  1340    * core: Plugins are searched for in the same directory as the executable
  1341        before the PATH. [GH-157]
  1342    * command/apply: "tfvars" file no longer interferes with plan apply. [GH-153]
  1343    * providers/aws: Fix issues around failing to read EIPs. [GH-122]
  1344    * providers/aws: Autoscaling groups now register and export load
  1345      balancers. [GH-207]
  1346    * providers/aws: Ingress results are treated as a set, so order doesn't
  1347        matter anymore. [GH-87]
  1348    * providers/aws: Instance security groups treated as a set [GH-194]
  1349    * providers/aws: Retry Route53 requests if operation failed because another

  1359        heroku\_addon work. [GH-198]
  1360  
  1361  PLUGIN CHANGES:
  1362  
  1363    * **New Package:** `helper/schema`. This introduces a high-level framework
  1364      for easily writing new providers and resources. The Heroku provider has
  1365      been converted to this as an example.
  1366  
  1367  ## 0.1.1 (August 5, 2014)
