     1  ## 0.7 (Unreleased)
     2  
     3  BACKWARDS INCOMPATIBILITIES / NOTES:
     4  
     5   * 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.
     6   * 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.)
     7   * The `concat()` interpolation function can no longer be used to join strings.
     8   * Quotation marks may no longer be escaped in HIL expressions [GH-7201]
     9   * `openstack_networking_subnet_v2` now defaults to turning DHCP on.
    10   * `aws_elb` now defaults `cross_zone_load_balancing` to `true`
    11   * `resource_aws_instance`: EC2 Classic users may continue to use
    12     `security_groups` to reference Security Groups by their `name`. Users who are
    13     managing Instances inside VPCs will need to use `vpc_security_group_ids` instead, 
    14     and reference the security groups by their `id`. 
    15     Ref https://github.com/hashicorp/terraform/issues/6416#issuecomment-219145065
    16   * 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.
    17   * `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 [GH-7375]
    18   * `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 . [GH-6954]
    19   * You now access the values of maps using the syntax `var.map["key"]` or the `lookup` function instead of `var.map.key`.
    20   * 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`.
    21   * `azurerm_dns_cname_record` now accepts a single record rather than a list of records
    22   * `aws_db_instance` now defaults `publicly_accessible` to false
    23   * `openstack_fw_policy_v1` now correctly applies rules in the order they are specified. Upon the next apply, current rules might be re-ordered.
    24   * `atlas_artifact` resource has be depracated. Please use the new `atlas_artifact` Data Source
    25   * The `member` attribute of `openstack_lb_pool_v1` has been deprecated. Please ue the new `openstack_lb_member_v1` resource.
    26

   651  
   652  ## 0.6.10 (January 27, 2016)
   653  
   654  BACKWARDS INCOMPATIBILITIES / NOTES:
   655  
   656    * The `-module-depth` flag available on `plan`, `apply`, `show`, and `graph` now defaults to `-1`, causing
   657      resources within modules to be expanded in command output. This is only a cosmetic change; it does not affect
   658      any behavior.
   659    * This release includes a bugfix for `$${}` interpolation escaping. These strings are now properly converted to `${}`
   660      during interpolation. This may cause diffs on existing configurations in certain cases.
   661    * 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.
   662    * 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.
   663    * 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.
   664

  1220       will load from other sources.

  1595  ## 0.4.2 (April 10, 2015)
  1596  
  1597  BUG FIXES:

  1606  
  1607  ## 0.4.1 (April 9, 2015)
  1608  
  1609  IMPROVEMENTS:
  1610  
  1611    * provider/aws: Route 53 records can now update `ttl` and `records` attributes
  1612        without destroying/creating the record ([#1396](https://github.com/hashicorp/terraform/issues/1396))
  1613    * provider/aws: Support changing additional attributes of RDS databases
  1614        without forcing a new resource  ([#1382](https://github.com/hashicorp/terraform/issues/1382))
  1615  
  1616  BUG FIXES:
  1617  
  1618    * core: module paths in ".terraform" are consistent across different
  1619        systems so copying your ".terraform" folder works. ([#1418](https://github.com/hashicorp/terraform/issues/1418))
  1620    * core: don't validate providers too early when nested in a module ([#1380](https://github.com/hashicorp/terraform/issues/1380))

  1644  
  1645  ## 0.4.0 (April 2, 2015)
  1646  
  1647  BACKWARDS INCOMPATIBILITIES:
  1648  
  1649    * Commands `terraform push` and `terraform pull` are now nested under
  1650      the `remote` command: `terraform remote push` and `terraform remote pull`.
  1651      The old `remote` functionality is now at `terraform remote config`. This
  1652      consolidates all remote state management under one command.
  1653    * Period-prefixed configuration files are now ignored. This might break
  1654      existing Terraform configurations if you had period-prefixed files.
  1655    * The `block_device` attribute of `aws_instance` has been removed in favor
  1656      of three more specific attributes to specify block device mappings:
  1657      `root_block_device`, `ebs_block_device`, and `ephemeral_block_device`.
  1658      Configurations using the old attribute will generate a validation error
  1659      indicating that they must be updated to use the new fields ([#1045](https://github.com/hashicorp/terraform/issues/1045)).
  1660  
  1661  FEATURES:
  1662  
  1663    * **New provider: `dme` (DNSMadeEasy)** ([#855](https://github.com/hashicorp/terraform/issues/855))
  1664    * **New provider: `docker` (Docker)** - Manage container lifecycle
  1665        using the standard Docker API. ([#855](https://github.com/hashicorp/terraform/issues/855))
  1666    * **New provider: `openstack` (OpenStack)** - Interact with the many resources
  1667        provided by OpenStack. ([#924](https://github.com/hashicorp/terraform/issues/924))
  1668    * **New feature: `terraform_remote_state` resource** - Reference remote
  1669        states from other Terraform runs to use Terraform outputs as inputs
  1670        into another Terraform run.
  1671    * **New command: `taint`** - Manually mark a resource as tainted, causing
  1672        a destroy and recreate on the next plan/apply.
  1673    * **New resource: `aws_vpn_gateway`** ([#1137](https://github.com/hashicorp/terraform/issues/1137))
  1674    * **New resource: `aws_elastic_network_interfaces`** ([#1149](https://github.com/hashicorp/terraform/issues/1149))
  1675    * **Self-variables** can be used to reference the current resource's
  1676        attributes within a provisioner. Ex. `${self.private_ip_address}` ([#1033](https://github.com/hashicorp/terraform/issues/1033))
  1677    * **Continuous state** saving during `terraform apply`. The state file is
  1678        continuously updated as apply is running, meaning that the state is
  1679        less likely to become corrupt in a catastrophic case: terraform panic
  1680        or system killing Terraform.
  1681    * **Math operations** in interpolations. You can now do things like
  1682        `${count.index + 1}`. ([#1068](https://github.com/hashicorp/terraform/issues/1068))
  1683    * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go),
  1684        a fork of the official `awslabs` repo. We forked for stability while
  1685        `awslabs` refactored the library, and will move back to the officially
  1686        supported version in the next release.
  1687  
  1688  IMPROVEMENTS:
  1689  
  1690    * **New config function: `format`** - Format a string using `sprintf`
  1691        format. ([#1096](https://github.com/hashicorp/terraform/issues/1096))
  1692    * **New config function: `replace`** - Search and replace string values.
  1693        Search can be a regular expression. See documentation for more
  1694        info. ([#1029](https://github.com/hashicorp/terraform/issues/1029))
  1695    * **New config function: `split`** - Split a value based on a delimiter.
  1696        This is useful for faking lists as parameters to modules.
  1697    * **New resource: `digitalocean_ssh_key`** ([#1074](https://github.com/hashicorp/terraform/issues/1074))
  1698    * config: Expand `~` with homedir in `file()` paths ([#1338](https://github.com/hashicorp/terraform/issues/1338))
  1699    * core: The serial of the state is only updated if there is an actual
  1700        change. This will lower the amount of state changing on things
  1701        like refresh.
  1702    * core: Autoload `terraform.tfvars.json` as well as `terraform.tfvars` ([#1030](https://github.com/hashicorp/terraform/issues/1030))
  1703    * core: `.tf` files that start with a period are now ignored. ([#1227](https://github.com/hashicorp/terraform/issues/1227))
  1704    * command/remote-config: After enabling remote state, a `pull` is
  1705        automatically done initially.
  1706    * providers/google: Add `size` option to disk blocks for instances. ([#1284](https://github.com/hashicorp/terraform/issues/1284))
  1707    * providers/aws: Improve support for tagging resources.
  1708    * providers/aws: Add a short syntax for Route 53 Record names, e.g.
  1709        `www` instead of `www.example.com`.
  1710    * providers/aws: Improve dependency violation error handling, when deleting
  1711        Internet Gateways or Auto Scaling groups ([#1325](https://github.com/hashicorp/terraform/issues/1325)).
  1712    * provider/aws: Add non-destructive updates to AWS RDS. You can now upgrade
  1713        `engine_version`, `parameter_group_name`, and `multi_az` without forcing
  1714        a new database to be created.([#1341](https://github.com/hashicorp/terraform/issues/1341))
  1715    * providers/aws: Full support for block device mappings on instances and
  1716        launch configurations [GH-1045, GH-1364]
  1717    * provisioners/remote-exec: SSH agent support. ([#1208](https://github.com/hashicorp/terraform/issues/1208))
  1718  
  1719  BUG FIXES:
  1720  
  1721    * core: module outputs can be used as inputs to other modules ([#822](https://github.com/hashicorp/terraform/issues/822))
  1722    * core: Self-referencing splat variables are no longer allowed in

  1726    * core: Fix invalid plan that resulted in "diffs don't match" error when
  1727        a computed attribute was used as part of a set parameter. ([#1073](https://github.com/hashicorp/terraform/issues/1073))
  1728    * core: Fix edge case where state containing both "resource" and
  1729        "resource.0" would ignore the latter completely. ([#1086](https://github.com/hashicorp/terraform/issues/1086))
  1730    * core: Modules with a source of a relative file path moving up
  1731        directories work properly, i.e. "../a" ([#1232](https://github.com/hashicorp/terraform/issues/1232))

  1760  
  1761  ## 0.3.7 (February 19, 2015)
  1762  
  1763  IMPROVEMENTS:
  1764  
  1765    * **New resources: `google_compute_forwarding_rule`, `google_compute_http_health_check`,
  1766        and `google_compute_target_pool`** - Together these provide network-level
  1767        load balancing. ([#588](https://github.com/hashicorp/terraform/issues/588))
  1768    * **New resource: `aws_main_route_table_association`** - Manage the main routing table
  1769        of a VPC. ([#918](https://github.com/hashicorp/terraform/issues/918))

  1772        very heavily.
  1773    * core: Strings in interpolations can now contain further interpolations,
  1774        e.g.: `foo ${bar("${baz}")}`.

  1776    * provider/aws: Support the more standard environmental variable names
  1777        for access key and secret keys. ([#851](https://github.com/hashicorp/terraform/issues/851))
  1778    * provider/aws: The `aws_db_instance` resource no longer requires both
  1779        `final_snapshot_identifier` and `skip_final_snapshot`; the presence or
  1780        absence of the former now implies the latter. ([#874](https://github.com/hashicorp/terraform/issues/874))
  1781    * provider/aws: Avoid unnecessary update of `aws_subnet` when
  1782        `map_public_ip_on_launch` is not specified in config. ([#898](https://github.com/hashicorp/terraform/issues/898))
  1783    * provider/aws: Add `apply_method` to `aws_db_parameter_group` ([#897](https://github.com/hashicorp/terraform/issues/897))

  1788    * provider/aws: Add `root_block_device` to `aws_db_instance` ([#998](https://github.com/hashicorp/terraform/issues/998))
  1789    * provider/google: Remove "client secrets file", as it's no longer necessary
  1790        for API authentication ([#884](https://github.com/hashicorp/terraform/issues/884)).
  1791    * provider/google: Expose `self_link` on `google_compute_instance` ([#906](https://github.com/hashicorp/terraform/issues/906))
  1792  
  1793  BUG FIXES:

  1802    * core: Sort `depends_on` in state to prevent unnecessary file changes. ([#928](https://github.com/hashicorp/terraform/issues/928))
  1803    * core: State containing the zero value won't cause a diff with the
  1804        lack of a value. ([#952](https://github.com/hashicorp/terraform/issues/952))
  1805    * core: If a set type becomes empty, the state will be properly updated
  1806        to remove it. ([#952](https://github.com/hashicorp/terraform/issues/952))
  1807    * core: Bare "splat" variables are not allowed in provisioners. ([#636](https://github.com/hashicorp/terraform/issues/636))
  1808    * core: Invalid configuration keys to sub-resources are now errors. ([#740](https://github.com/hashicorp/terraform/issues/740))
  1809    * command/apply: Won't try to initialize modules in some cases when
  1810        no arguments are given. ([#780](https://github.com/hashicorp/terraform/issues/780))
  1811    * command/apply: Fix regression where user variables weren't asked ([#736](https://github.com/hashicorp/terraform/issues/736))
  1812    * helper/hashcode: Update `hash.String()` to always return a positive index.
  1813        Fixes issue where specific strings would convert to a negative index
  1814        and be omitted when creating Route53 records. ([#967](https://github.com/hashicorp/terraform/issues/967))
  1815    * provider/aws: Automatically suffix the Route53 zone name on record names. ([#312](https://github.com/hashicorp/terraform/issues/312))
  1816    * provider/aws: Instance should ignore root EBS devices. ([#877](https://github.com/hashicorp/terraform/issues/877))
  1817    * provider/aws: Fix `aws_db_instance` to not recreate each time. ([#874](https://github.com/hashicorp/terraform/issues/874))

  1826        created ([#884](https://github.com/hashicorp/terraform/issues/884)).
  1827  
  1828  PLUGIN CHANGES:
  1829  
  1830    * New `helper/schema` type: `TypeFloat` ([#594](https://github.com/hashicorp/terraform/issues/594))
  1831    * New `helper/schema` field for resources: `Exists` must point to a function
  1832        to check for the existence of a resource. This is used to properly
  1833        handle the case where the resource was manually deleted. ([#766](https://github.com/hashicorp/terraform/issues/766))
  1834    * There is a semantic change in `GetOk` where it will return `true` if
  1835        there is any value in the diff that is _non-zero_. Before, it would
  1836        return true only if there was a value in the diff.

  1857    * core: Set types in resources now result in deterministic states,
  1858        resulting in cleaner plans. ([#663](https://github.com/hashicorp/terraform/issues/663))
  1859    * core: fix issue where "diff was not the same" would come up with
  1860        diffing lists. ([#661](https://github.com/hashicorp/terraform/issues/661))
  1861    * core: fix crash where module inputs weren't strings, and add more
  1862        validation around invalid types here. ([#624](https://github.com/hashicorp/terraform/issues/624))
  1863    * core: fix error when using a computed module output as an input to
  1864        another module. ([#659](https://github.com/hashicorp/terraform/issues/659))
  1865    * core: map overrides in "terraform.tfvars" no longer result in a syntax
  1866        error. ([#647](https://github.com/hashicorp/terraform/issues/647))

  1874        in more accurate diffs for AWS instances. ([#712](https://github.com/hashicorp/terraform/issues/712))
  1875    * provider/aws: Fix panic case by using the wrong type when setting
  1876        volume size for AWS instances. ([#712](https://github.com/hashicorp/terraform/issues/712))
  1877    * provider/aws: route table ignores routes with 'EnableVgwRoutePropagation'
  1878        origin since those come from gateways. ([#722](https://github.com/hashicorp/terraform/issues/722))
  1879    * provider/aws: Default network ACL ID and default security group ID
  1880        support for `aws_vpc`. ([#704](https://github.com/hashicorp/terraform/issues/704))
  1881    * provider/aws: Tags are not marked as computed. This introduces another
  1882        issue with not detecting external tags, but this will be fixed in
  1883        the future. ([#730](https://github.com/hashicorp/terraform/issues/730))
  1884

  1957    * core: If a resource fails to create and has provisioners, it is
  1958        marked as tainted. ([#434](https://github.com/hashicorp/terraform/issues/434))
  1959    * core: Set types are validated to be sets. ([#413](https://github.com/hashicorp/terraform/issues/413))

  1987  
  1988  ## 0.3.0 (October 14, 2014)
  1989  
  1990  FEATURES:
  1991  
  1992    * **Modules**: Configuration can now be modularized. Modules can live on
  1993      GitHub, BitBucket, Git/Hg repos, HTTP URLs, and file paths. Terraform
  1994      automatically downloads/updates modules for you on request.
  1995    * **New Command: `init`**. This command initializes a Terraform configuration
  1996      from an existing Terraform module (also new in 0.3).
  1997    * **New Command: `destroy`**. This command destroys infrastructure
  1998      created with `apply`.
  1999    * Terraform will ask for user input to fill in required variables and
  2000      provider configurations if they aren't set.
  2001    * `terraform apply MODULE` can be used as a shorthand to quickly build
  2002      infrastructure from a module.
  2003    * The state file format is now JSON rather than binary. This allows for
  2004      easier machine and human read/write. Old binary state files will be
  2005      automatically upgraded.
  2006    * You can now specify `create_before_destroy` as an option for replacement
  2007      so that new resources are created before the old ones are destroyed.
  2008    * The `count` metaparameter can now contain interpolations (such as
  2009      variables).
  2010    * The current index for a resource with a `count` set can be interpolated
  2011      using `${count.index}`.
  2012    * Various paths can be interpolated with the `path.X` variables. For example,
  2013      the path to the current module can be interpolated using `${path.module}`.
  2014  
  2015  IMPROVEMENTS:
  2016  
  2017    * config: Trailing commas are now allowed for the final elements of lists.
  2018    * core: Plugins are loaded from `~/.terraform.d/plugins` (Unix) or
  2019      `%USERDATA%/terraform.d/plugins` (Windows).
  2020    * command/show: With no arguments, it will show the default state. ([#349](https://github.com/hashicorp/terraform/issues/349))
  2021    * helper/schema: Can now have default values. ([#245](https://github.com/hashicorp/terraform/issues/245))

  2023    * providers/aws: New resource `db_subnet_group`. ([#295](https://github.com/hashicorp/terraform/issues/295))
  2024    * providers/aws: Add `map_public_ip_on_launch` for subnets. ([#285](https://github.com/hashicorp/terraform/issues/285))
  2025    * providers/aws: Add `iam_instance_profile` for instances. ([#319](https://github.com/hashicorp/terraform/issues/319))
  2026    * providers/aws: Add `internal` option for ELBs. ([#303](https://github.com/hashicorp/terraform/issues/303))
  2027    * providers/aws: Add `ssl_certificate_id` for ELB listeners. ([#350](https://github.com/hashicorp/terraform/issues/350))
  2028    * providers/aws: Add `self` option for security groups for ingress
  2029        rules with self as source. ([#303](https://github.com/hashicorp/terraform/issues/303))
  2030    * providers/aws: Add `iam_instance_profile` option to
  2031        `aws_launch_configuration`. ([#371](https://github.com/hashicorp/terraform/issues/371))

  2113  
  2114  BACKWARDS INCOMPATIBILITIES:
  2115  
  2116    * We've replaced the configuration language in use from a C library to
  2117      a pure-Go reimplementation. In the process, we removed some features
  2118      of the language since it was too flexible:
  2119      * Semicolons are no longer valid at the end of lines
  2120      * Keys cannot be double-quoted strings: `"foo" = "bar"` is no longer
  2121        valid.
  2122      * JSON style maps `{ "foo": "bar" }` are no longer valid outside of JSON.
  2123        Maps must be in the format of `{ foo = "bar" }` (like other objects
  2124        in the config)
  2125    * Heroku apps now require (will not validate without) `region` and
  2126      `name` due to an upstream API change. ([#239](https://github.com/hashicorp/terraform/issues/239))

  2135  
  2136  IMPROVEMENTS:
  2137  
  2138    * core: "~/.terraformrc" (Unix) or "%APPDATA%/terraform.rc" (Windows)

  2179  
  2180    * **New Package:** `helper/schema`. This introduces a high-level framework
  2181      for easily writing new providers and resources. The Heroku provider has
