terraform/CHANGELOG.md

0.7 (Unreleased)

BACKWARDS INCOMPATIBILITIES / NOTES:

• 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 concat() interpolation function can no longer be used to join strings.
• openstack_networking_subnet_v2 now defaults to turning DHCP on.

0.6.11 (February 1, 2016)

BACKWARDS INCOMPATIBILITIES / NOTES:

• The max_size, min_size and desired_capacity attributes on aws_autoscaling_schedule resources now default to 0

FEATURES:

• New provider: powerdns - PowerDNS REST API (#4885)
• New builtin function: trimspace for trimming whitespaces (#4910)

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.

0.5.1 (never released)

This version was never released since we accidentally skipped it!

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.

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).

FEATURES:

• New provider: dme (DNSMadeEasy) (#855)
• New provider: docker (Docker) - Manage container lifecycle using the standard Docker API. (#855)
• New provider: openstack (OpenStack) - Interact with the many resources provided by OpenStack. (#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)
• New resource: aws_elastic_network_interfaces (#1149)
• Self-variables can be used to reference the current resource's attributes within a provisioner. Ex. ${self.private_ip_address} (#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)
• 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)
• New config function: replace - Search and replace string values. Search can be a regular expression. See documentation for more info. (#1029)

• providers/aws: Full support for block device mappings on instances and launch configurations [GH-1045, GH-1364]
• provisioners/remote-exec: SSH agent support. (#1208)

• core: module outputs can be used as inputs to other modules (#822)
• core: Self-referencing splat variables are no longer allowed in provisioners. (#795)(#868)
• core: Validate that depends_on doesn't contain interpolations. (#1015)
• core: Module inputs can be non-strings. (#819)
• core: Fix invalid plan that resulted in "diffs don't match" error when a computed attribute was used as part of a set parameter. (#1073)
• core: Fix edge case where state containing both "resource" and "resource.0" would ignore the latter completely. (#1086)

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)

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)
• 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)
• providers/aws: Can specify a private IP address for aws_instance (#217)

• core: Variables are validated to not contain interpolations. (#180)
• core: Key files for provisioning can now contain ~ and will be expanded to the user's home directory. (#179)
• core: The file() function can load files in sub-directories. (#213)
• core: Fix issue where some JSON structures didn't map properly into Terraform structures. (#177)
• core: Resources with only file() calls will interpolate. (#159)
• core: Variables work in block names. (#234)
• core: Plugins are searched for in the same directory as the executable before the PATH. (#157)
• command/apply: "tfvars" file no longer interferes with plan apply. (#153)
• providers/aws: Fix issues around failing to read EIPs. (#122)
• providers/aws: Autoscaling groups now register and export load balancers. (#207)

• providers/aws: Instance security groups treated as a set (#194)
• providers/aws: Retry Route53 requests if operation failed because another operation is in progress (#183)
• providers/aws: Route53 records with multiple record values work. (#221)
