   200    * provider/openstack: Ability to specify per-network Floating IPs ([#4812](https://github.com/hashicorp/terraform/issues/4812)) 
   201

   203  
   204    * provider/aws: `aws_autoscale_schedule` 0 values ([#4693](https://github.com/hashicorp/terraform/issues/4693))

   214  
   215  ## 0.6.10 (January 27, 2016)
   216  
   217  BACKWARDS INCOMPATIBILITIES / NOTES:
   218  
   219    * The `-module-depth` flag available on `plan`, `apply`, `show`, and `graph` now defaults to `-1`, causing
   220      resources within modules to be expanded in command output. This is only a cosmetic change; it does not affect
   221      any behavior.
   222    * This release includes a bugfix for `$${}` interpolation escaping. These strings are now properly converted to `${}`
   223      during interpolation. This may cause diffs on existing configurations in certain cases.
   224    * 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.
   225    * 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.
   226    * 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.
   227

   771  ## 0.6.0 (June 30, 2015)
   772  
   773  BACKWARDS INCOMPATIBILITIES:
   774  
   775   * command/push: If a variable is already set within Atlas, it won't be
   776       updated unless the `-overwrite` flag is present ([#2373](https://github.com/hashicorp/terraform/issues/2373))
   777   * connection/ssh: The `agent` field now defaults to `true` if
   778       the `SSH_AGENT_SOCK` environment variable is present. In other words,
   779       `ssh-agent` support is now opt-out instead of opt-in functionality. ([#2408](https://github.com/hashicorp/terraform/issues/2408))
   780   * provider/aws: If you were setting access and secret key to blank ("")
   781       to force Terraform to load credentials from another source such as the
   782       EC2 role, this will now error. Remove the blank lines and Terraform
   783       will load from other sources.
   784   * `concat()` has been repurposed to combine lists instead of strings (old behavior
   785       of joining strings is maintained in this version but is deprecated, strings
   786       should be combined using interpolation syntax, like "${var.foo}{var.bar}")

  1158  ## 0.4.2 (April 10, 2015)
  1159  
  1160  BUG FIXES:
  1161  
  1162    * core: refresh won't remove outputs from state file ([#1369](https://github.com/hashicorp/terraform/issues/1369))
  1163    * core: clarify "unknown variable" error ([#1480](https://github.com/hashicorp/terraform/issues/1480))

  1168        `network` field on `google_compute_instance` ([#1458](https://github.com/hashicorp/terraform/issues/1458))
  1169  
  1170  ## 0.4.1 (April 9, 2015)
  1171  
  1172  IMPROVEMENTS:
  1173  
  1174    * provider/aws: Route 53 records can now update `ttl` and `records` attributes
  1175        without destroying/creating the record ([#1396](https://github.com/hashicorp/terraform/issues/1396))
  1176    * provider/aws: Support changing additional attributes of RDS databases
  1177        without forcing a new resource  ([#1382](https://github.com/hashicorp/terraform/issues/1382))
  1178  
  1179  BUG FIXES:
  1180  
  1181    * core: module paths in ".terraform" are consistent across different
  1182        systems so copying your ".terraform" folder works. ([#1418](https://github.com/hashicorp/terraform/issues/1418))
  1183    * core: don't validate providers too early when nested in a module ([#1380](https://github.com/hashicorp/terraform/issues/1380))
  1184    * core: fix race condition in `count.index` interpolation ([#1454](https://github.com/hashicorp/terraform/issues/1454))
  1185    * core: properly initialize provisioners, fixing resource targeting
  1186        during destroy ([#1544](https://github.com/hashicorp/terraform/issues/1544))
  1187    * command/push: don't ask for input if terraform.tfvars is present
  1188    * command/remote-config: remove spurrious error "nil" when initializing
  1189        remote state on a new configuration. ([#1392](https://github.com/hashicorp/terraform/issues/1392))
  1190    * provider/aws: Fix issue with Route 53 and pre-existing Hosted Zones ([#1415](https://github.com/hashicorp/terraform/issues/1415))
  1191    * provider/aws: Fix refresh issue in Route 53 hosted zone ([#1384](https://github.com/hashicorp/terraform/issues/1384))
  1192    * provider/aws: Fix issue when changing map-public-ip in Subnets #1234
  1193    * provider/aws: Fix issue finding db subnets ([#1377](https://github.com/hashicorp/terraform/issues/1377))
  1194    * provider/aws: Fix issues with `*_block_device` attributes on instances and
  1195        launch configs creating unresolvable diffs when certain optional
  1196        parameters were omitted from the config ([#1445](https://github.com/hashicorp/terraform/issues/1445))
  1197    * provider/aws: Fix issue with `aws_launch_configuration` causing an
  1198        unnecessary diff for pre-0.4 environments ([#1371](https://github.com/hashicorp/terraform/issues/1371))

  1205    * provider/google: Fix issue causing unresolvable diff on instances with
  1206        `network_interface` ([#1427](https://github.com/hashicorp/terraform/issues/1427))
  1207  
  1208  ## 0.4.0 (April 2, 2015)
  1209  
  1210  BACKWARDS INCOMPATIBILITIES:
  1211  
  1212    * Commands `terraform push` and `terraform pull` are now nested under
  1213      the `remote` command: `terraform remote push` and `terraform remote pull`.
  1214      The old `remote` functionality is now at `terraform remote config`. This
  1215      consolidates all remote state management under one command.
  1216    * Period-prefixed configuration files are now ignored. This might break
  1217      existing Terraform configurations if you had period-prefixed files.
  1218    * The `block_device` attribute of `aws_instance` has been removed in favor
  1219      of three more specific attributes to specify block device mappings:
  1220      `root_block_device`, `ebs_block_device`, and `ephemeral_block_device`.
  1221      Configurations using the old attribute will generate a validation error
  1222      indicating that they must be updated to use the new fields ([#1045](https://github.com/hashicorp/terraform/issues/1045)).
  1223  
  1224  FEATURES:
  1225  
  1226    * **New provider: `dme` (DNSMadeEasy)** ([#855](https://github.com/hashicorp/terraform/issues/855))
  1227    * **New provider: `docker` (Docker)** - Manage container lifecycle
  1228        using the standard Docker API. ([#855](https://github.com/hashicorp/terraform/issues/855))
  1229    * **New provider: `openstack` (OpenStack)** - Interact with the many resources
  1230        provided by OpenStack. ([#924](https://github.com/hashicorp/terraform/issues/924))
  1231    * **New feature: `terraform_remote_state` resource** - Reference remote
  1232        states from other Terraform runs to use Terraform outputs as inputs
  1233        into another Terraform run.
  1234    * **New command: `taint`** - Manually mark a resource as tainted, causing
  1235        a destroy and recreate on the next plan/apply.
  1236    * **New resource: `aws_vpn_gateway`** ([#1137](https://github.com/hashicorp/terraform/issues/1137))
  1237    * **New resource: `aws_elastic_network_interfaces`** ([#1149](https://github.com/hashicorp/terraform/issues/1149))
  1238    * **Self-variables** can be used to reference the current resource's
  1239        attributes within a provisioner. Ex. `${self.private_ip_address}` ([#1033](https://github.com/hashicorp/terraform/issues/1033))
  1240    * **Continuous state** saving during `terraform apply`. The state file is
  1241        continuously updated as apply is running, meaning that the state is
  1242        less likely to become corrupt in a catastrophic case: terraform panic
  1243        or system killing Terraform.
  1244    * **Math operations** in interpolations. You can now do things like
  1245        `${count.index + 1}`. ([#1068](https://github.com/hashicorp/terraform/issues/1068))
  1246    * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go),
  1247        a fork of the official `awslabs` repo. We forked for stability while
  1248        `awslabs` refactored the library, and will move back to the officially
  1249        supported version in the next release.
  1250  
  1251  IMPROVEMENTS:
  1252  
  1253    * **New config function: `format`** - Format a string using `sprintf`
  1254        format. ([#1096](https://github.com/hashicorp/terraform/issues/1096))
  1255    * **New config function: `replace`** - Search and replace string values.
  1256        Search can be a regular expression. See documentation for more
  1257        info. ([#1029](https://github.com/hashicorp/terraform/issues/1029))
  1258    * **New config function: `split`** - Split a value based on a delimiter.
  1259        This is useful for faking lists as parameters to modules.
  1260    * **New resource: `digitalocean_ssh_key`** ([#1074](https://github.com/hashicorp/terraform/issues/1074))
  1261    * config: Expand `~` with homedir in `file()` paths ([#1338](https://github.com/hashicorp/terraform/issues/1338))
  1262    * core: The serial of the state is only updated if there is an actual
  1263        change. This will lower the amount of state changing on things
  1264        like refresh.
  1265    * core: Autoload `terraform.tfvars.json` as well as `terraform.tfvars` ([#1030](https://github.com/hashicorp/terraform/issues/1030))
  1266    * core: `.tf` files that start with a period are now ignored. ([#1227](https://github.com/hashicorp/terraform/issues/1227))
  1267    * command/remote-config: After enabling remote state, a `pull` is
  1268        automatically done initially.
  1269    * providers/google: Add `size` option to disk blocks for instances. ([#1284](https://github.com/hashicorp/terraform/issues/1284))
  1270    * providers/aws: Improve support for tagging resources.
  1271    * providers/aws: Add a short syntax for Route 53 Record names, e.g.
  1272        `www` instead of `www.example.com`.
  1273    * providers/aws: Improve dependency violation error handling, when deleting
  1274        Internet Gateways or Auto Scaling groups ([#1325](https://github.com/hashicorp/terraform/issues/1325)).
  1275    * provider/aws: Add non-destructive updates to AWS RDS. You can now upgrade
  1276        `engine_version`, `parameter_group_name`, and `multi_az` without forcing
  1277        a new database to be created.([#1341](https://github.com/hashicorp/terraform/issues/1341))
  1278    * providers/aws: Full support for block device mappings on instances and
  1279        launch configurations [GH-1045, GH-1364]
  1280    * provisioners/remote-exec: SSH agent support. ([#1208](https://github.com/hashicorp/terraform/issues/1208))
  1281  
  1282  BUG FIXES:
  1283  
  1284    * core: module outputs can be used as inputs to other modules ([#822](https://github.com/hashicorp/terraform/issues/822))
  1285    * core: Self-referencing splat variables are no longer allowed in
  1286        provisioners. ([#795](https://github.com/hashicorp/terraform/issues/795))([#868](https://github.com/hashicorp/terraform/issues/868))
  1287    * core: Validate that `depends_on` doesn't contain interpolations. ([#1015](https://github.com/hashicorp/terraform/issues/1015))

  1289    * core: Fix invalid plan that resulted in "diffs don't match" error when
  1290        a computed attribute was used as part of a set parameter. ([#1073](https://github.com/hashicorp/terraform/issues/1073))
  1291    * core: Fix edge case where state containing both "resource" and
  1292        "resource.0" would ignore the latter completely. ([#1086](https://github.com/hashicorp/terraform/issues/1086))
  1293    * core: Modules with a source of a relative file path moving up
  1294        directories work properly, i.e. "../a" ([#1232](https://github.com/hashicorp/terraform/issues/1232))
  1295    * providers/aws: manually deleted VPC removes it from the state
  1296    * providers/aws: `source_dest_check` regression fixed (now works). ([#1020](https://github.com/hashicorp/terraform/issues/1020))
  1297    * providers/aws: Longer wait times for DB instances.

  1299    * providers/aws: Fix support for TXT records in Route 53. ([#1213](https://github.com/hashicorp/terraform/issues/1213))
  1300    * providers/aws: Fix support for wildcard records in Route 53. ([#1222](https://github.com/hashicorp/terraform/issues/1222))
  1301    * providers/aws: Fix issue with ignoring the 'self' attribute of a
  1302        Security Group rule. ([#1223](https://github.com/hashicorp/terraform/issues/1223))
  1303    * providers/aws: Fix issue with `sql_mode` in RDS parameter group always
  1304        causing an update. ([#1225](https://github.com/hashicorp/terraform/issues/1225))
  1305    * providers/aws: Fix dependency violation with subnets and security groups
  1306        ([#1252](https://github.com/hashicorp/terraform/issues/1252))

  1308        instead of updating state ([#1254](https://github.com/hashicorp/terraform/issues/1254))
  1309    * providers/aws: Prevent empty string to be used as default
  1310        `health_check_type` ([#1052](https://github.com/hashicorp/terraform/issues/1052))
  1311    * providers/aws: Add tags on AWS IG creation, not just on update ([#1176](https://github.com/hashicorp/terraform/issues/1176))
  1312    * providers/digitalocean: Waits until droplet is ready to be destroyed ([#1057](https://github.com/hashicorp/terraform/issues/1057))
  1313    * providers/digitalocean: More lenient about 404's while waiting ([#1062](https://github.com/hashicorp/terraform/issues/1062))
  1314    * providers/digitalocean: FQDN for domain records in CNAME, MX, NS, etc.
  1315        Also fixes invalid updates in plans. ([#863](https://github.com/hashicorp/terraform/issues/863))
  1316    * providers/google: Network data in state was not being stored. ([#1095](https://github.com/hashicorp/terraform/issues/1095))
  1317    * providers/heroku: Fix panic when config vars block was empty. ([#1211](https://github.com/hashicorp/terraform/issues/1211))
  1318  
  1319  PLUGIN CHANGES:
  1320  
  1321    * New `helper/schema` fields for resources: `Deprecated` and `Removed` allow
  1322        plugins to generate warning or error messages when a given attribute is used.
  1323  
  1324  ## 0.3.7 (February 19, 2015)
  1325  
  1326  IMPROVEMENTS:
  1327  
  1328    * **New resources: `google_compute_forwarding_rule`, `google_compute_http_health_check`,
  1329        and `google_compute_target_pool`** - Together these provide network-level
  1330        load balancing. ([#588](https://github.com/hashicorp/terraform/issues/588))
  1331    * **New resource: `aws_main_route_table_association`** - Manage the main routing table
  1332        of a VPC. ([#918](https://github.com/hashicorp/terraform/issues/918))
  1333    * **New resource: `aws_vpc_peering_connection`** ([#963](https://github.com/hashicorp/terraform/issues/963))
  1334    * core: Formalized the syntax of interpolations and documented it
  1335        very heavily.
  1336    * core: Strings in interpolations can now contain further interpolations,
  1337        e.g.: `foo ${bar("${baz}")}`.

  1341    * provider/aws: The `aws_db_instance` resource no longer requires both
  1342        `final_snapshot_identifier` and `skip_final_snapshot`; the presence or
  1343        absence of the former now implies the latter. ([#874](https://github.com/hashicorp/terraform/issues/874))
  1344    * provider/aws: Avoid unnecessary update of `aws_subnet` when
  1345        `map_public_ip_on_launch` is not specified in config. ([#898](https://github.com/hashicorp/terraform/issues/898))
  1346    * provider/aws: Add `apply_method` to `aws_db_parameter_group` ([#897](https://github.com/hashicorp/terraform/issues/897))

  1362    * core: Fix crash that could occur when there are exactly zero providers
  1363        installed on a system. ([#786](https://github.com/hashicorp/terraform/issues/786))
  1364    * core: JSON TF configurations can configure provisioners. ([#807](https://github.com/hashicorp/terraform/issues/807))
  1365    * core: Sort `depends_on` in state to prevent unnecessary file changes. ([#928](https://github.com/hashicorp/terraform/issues/928))
  1366    * core: State containing the zero value won't cause a diff with the
  1367        lack of a value. ([#952](https://github.com/hashicorp/terraform/issues/952))
  1368    * core: If a set type becomes empty, the state will be properly updated
  1369        to remove it. ([#952](https://github.com/hashicorp/terraform/issues/952))
  1370    * core: Bare "splat" variables are not allowed in provisioners. ([#636](https://github.com/hashicorp/terraform/issues/636))
  1371    * core: Invalid configuration keys to sub-resources are now errors. ([#740](https://github.com/hashicorp/terraform/issues/740))
  1372    * command/apply: Won't try to initialize modules in some cases when
  1373        no arguments are given. ([#780](https://github.com/hashicorp/terraform/issues/780))
  1374    * command/apply: Fix regression where user variables weren't asked ([#736](https://github.com/hashicorp/terraform/issues/736))
  1375    * helper/hashcode: Update `hash.String()` to always return a positive index.
  1376        Fixes issue where specific strings would convert to a negative index
  1377        and be omitted when creating Route53 records. ([#967](https://github.com/hashicorp/terraform/issues/967))
  1378    * provider/aws: Automatically suffix the Route53 zone name on record names. ([#312](https://github.com/hashicorp/terraform/issues/312))
  1379    * provider/aws: Instance should ignore root EBS devices. ([#877](https://github.com/hashicorp/terraform/issues/877))
  1380    * provider/aws: Fix `aws_db_instance` to not recreate each time. ([#874](https://github.com/hashicorp/terraform/issues/874))

  1389        created ([#884](https://github.com/hashicorp/terraform/issues/884)).
  1390  
  1391  PLUGIN CHANGES:
  1392  
  1393    * New `helper/schema` type: `TypeFloat` ([#594](https://github.com/hashicorp/terraform/issues/594))
  1394    * New `helper/schema` field for resources: `Exists` must point to a function
  1395        to check for the existence of a resource. This is used to properly
  1396        handle the case where the resource was manually deleted. ([#766](https://github.com/hashicorp/terraform/issues/766))
  1397    * There is a semantic change in `GetOk` where it will return `true` if
  1398        there is any value in the diff that is _non-zero_. Before, it would
  1399        return true only if there was a value in the diff.

  1438    * provider/aws: Fix panic case by using the wrong type when setting
  1439        volume size for AWS instances. ([#712](https://github.com/hashicorp/terraform/issues/712))
  1440    * provider/aws: route table ignores routes with 'EnableVgwRoutePropagation'
  1441        origin since those come from gateways. ([#722](https://github.com/hashicorp/terraform/issues/722))
  1442    * provider/aws: Default network ACL ID and default security group ID
  1443        support for `aws_vpc`. ([#704](https://github.com/hashicorp/terraform/issues/704))
  1444    * provider/aws: Tags are not marked as computed. This introduces another
  1445        issue with not detecting external tags, but this will be fixed in
  1446        the future. ([#730](https://github.com/hashicorp/terraform/issues/730))
  1447

  1550  
  1551  ## 0.3.0 (October 14, 2014)
  1552  
  1553  FEATURES:
  1554  
  1555    * **Modules**: Configuration can now be modularized. Modules can live on
  1556      GitHub, BitBucket, Git/Hg repos, HTTP URLs, and file paths. Terraform
  1557      automatically downloads/updates modules for you on request.
  1558    * **New Command: `init`**. This command initializes a Terraform configuration
  1559      from an existing Terraform module (also new in 0.3).
  1560    * **New Command: `destroy`**. This command destroys infrastructure
  1561      created with `apply`.
  1562    * Terraform will ask for user input to fill in required variables and
  1563      provider configurations if they aren't set.
  1564    * `terraform apply MODULE` can be used as a shorthand to quickly build
  1565      infrastructure from a module.
  1566    * The state file format is now JSON rather than binary. This allows for
  1567      easier machine and human read/write. Old binary state files will be
  1568      automatically upgraded.
  1569    * You can now specify `create_before_destroy` as an option for replacement
  1570      so that new resources are created before the old ones are destroyed.
  1571    * The `count` metaparameter can now contain interpolations (such as
  1572      variables).
  1573    * The current index for a resource with a `count` set can be interpolated
  1574      using `${count.index}`.
  1575    * Various paths can be interpolated with the `path.X` variables. For example,
  1576      the path to the current module can be interpolated using `${path.module}`.
  1577  
  1578  IMPROVEMENTS:
  1579  
  1580    * config: Trailing commas are now allowed for the final elements of lists.

  1601    * providers/google: `google_compute_disk` supports `type` to support disks
  1602        such as SSDs. ([#351](https://github.com/hashicorp/terraform/issues/351))

  1618    * providers/aws: Retry deleting subnet for some time while AWS eventually
  1619        destroys dependencies. ([#357](https://github.com/hashicorp/terraform/issues/357))
  1620    * providers/aws: More robust destroy for route53 records. ([#342](https://github.com/hashicorp/terraform/issues/342))
  1621    * providers/aws: ELB generates much more correct plans without extranneous
  1622        data.
  1623    * providers/aws: ELB works properly with dynamically changing
  1624        count of instances.
  1625    * providers/aws: Terraform can handle ELBs deleted manually. ([#304](https://github.com/hashicorp/terraform/issues/304))
  1626    * providers/aws: Report errors properly if RDS fails to delete. ([#310](https://github.com/hashicorp/terraform/issues/310))
  1627    * providers/aws: Wait for launch configuration to exist after creation
  1628        (AWS eventual consistency) ([#302](https://github.com/hashicorp/terraform/issues/302))
  1629  
  1630  ## 0.2.2 (September 9, 2014)
  1631  
  1632  IMPROVEMENTS:

  1678  
  1679    * We've replaced the configuration language in use from a C library to
  1680      a pure-Go reimplementation. In the process, we removed some features
  1681      of the language since it was too flexible:
  1682      * Semicolons are no longer valid at the end of lines
  1683      * Keys cannot be double-quoted strings: `"foo" = "bar"` is no longer
  1684        valid.
  1685      * JSON style maps `{ "foo": "bar" }` are no longer valid outside of JSON.
  1686        Maps must be in the format of `{ foo = "bar" }` (like other objects
  1687        in the config)
  1688    * Heroku apps now require (will not validate without) `region` and
  1689      `name` due to an upstream API change. ([#239](https://github.com/hashicorp/terraform/issues/239))
  1690  
  1691  FEATURES:
  1692  
  1693    * **New Provider: `google`**: Manage Google Compute instances, disks,
  1694        firewalls, and more.
  1695    * **New Provider: `mailgun`**: Manage mailgun domains.
  1696    * **New Function: `concat`**: Concatenate multiple strings together.
  1697      Example: `concat(var.region, "-", var.channel)`.
  1698  
  1699  IMPROVEMENTS:
  1700  
  1701    * core: "~/.terraformrc" (Unix) or "%APPDATA%/terraform.rc" (Windows)
  1702      can be used to configure custom providers and provisioners. ([#192](https://github.com/hashicorp/terraform/issues/192))
  1703    * providers/aws: EIPs now expose `allocation_id` and `public_ip`
