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]

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. [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:

core: "~/.terraformrc" (Unix) or "%APPDATA%/terraform.rc" (Windows) 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]
core: Key files for provisioning can now contain ~ and will be expanded to the user's home directory. [GH-179]
core: The file() function can load files in sub-directories. [GH-213]
core: Fix issue where some JSON structures didn't map properly into Terraform structures. [GH-177]
core: Resources with only file() calls will interpolate. [GH-159]
core: Variables work in block names. [GH-234]
core: Plugins are searched for in the same directory as the executable before the PATH. [GH-157]
command/apply: "tfvars" file no longer interferes with plan apply. [GH-153]
providers/aws: Fix issues around failing to read EIPs. [GH-122]
providers/aws: Autoscaling groups now register and export load balancers. [GH-207]
providers/aws: Ingress results are treated as a set, so order doesn't matter anymore. [GH-87]
providers/aws: Instance security groups treated as a set [GH-194]
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.
