terraform/CHANGELOG.md

0.2.0 (unreleased)

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  • Semicolons are no longer valid at the end of lines
  • Keys cannot be double-quoted strings: "foo" = "bar" is no longer valid.
  • JSON style maps { "foo": "bar" } are no longer valid outside of JSON.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)

FEATURES:

• 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.

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]
• providers/aws: Fix issues around failing to read EIPs. [GH-122]
• providers/heroku: If you delete the config_vars block, config vars are properly nuked.
• providers/heroku: Domains and drains are deleted before the app.

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.
