terraform/CHANGELOG.md at 623c635fb1185aa4ffb6de8bda4dd1df6524af9e

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- Semicolons are no longer valid at the end of lines
- Keys cannot be double-quoted strings: "foo" = "bar" is no longer valid.
- JSON style maps { "foo": "bar" } are no longer valid outside of JSON.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: Security group rules can be updated without a destroy/create.
providers/aws: You can enable and disable dns settings for VPCs. [GH-172]
