Ex. `${self.private_ip_address}` [GH-1033] 294 * **Continuous state** saving during `terraform apply`. The state file is 295 continuously updated as apply is running, meaning that the state is 296 less likely to become corrupt in a catastrophic case: terraform panic 297 or system killing Terraform. 298 * **Math operations** in interpolations. You can now do things like 299 `${count.index+1}`. [GH-1068] 300 * **New AWS SDK:** Move to `aws-sdk-go` (hashicorp/aws-sdk-go), 301 a fork of the offical `awslabs` repo.

This will lower the amount of state changing on things 318 like refresh. 319 * core: Autoload `terraform.tfvars.json` as well as `terraform.tfvars` [GH-1030] 320 * core: `.tf` files that start with a period are now ignored. [GH-1227] 321 * command/remote-config: After enabling remote state, a `pull` is 322 automatically done initially. 323 * providers/google: Add `size` option to disk blocks for instances. [GH-1284] 324 * providers/aws: Improve support for tagging resources. 325 * providers/aws: Add a short syntax for Route 53 Record names, e.g. 326 `www` instead of `www.example.com`. 327 * providers/aws: Improve dependency violation error handling, when deleting 328 Internet Gateways or Auto Scaling groups [GH-1325]. 329 * provider/aws: Add non-destructive updates to AWS RDS. You can now upgrade 330 `egine_version`, `parameter_group_name`, and `multi_az` without forcing 331 a new database to be created.[GH-1341] 332 * providers/aws: Full support for block device mappings on instances and 333 launch configurations [GH-1045, GH-1364] 334 * provisioners/remote-exec: SSH agent support.

[GH-819] 343 * core: Fix invalid plan that resulted in "diffs don't match" error when 344 a computed attribute was used as part of a set parameter. [GH-1073] 345 * core: Fix edge case where state containing both "resource" and 346 "resource.0" would ignore the latter completely. [GH-1086] 347 * core: Modules with a source of a relative file path moving up 348 directories work properly, i.e. "../a" [GH-1232] 349 * providers/aws: manually deleted VPC removes it from the state 350 * providers/aws: `source_dest_check` regression fixed (now works).

[GH-851] 395 * provider/aws: The `aws_db_instance` resource no longer requires both 396 `final_snapshot_identifier` and `skip_final_snapshot`; the presence or 397 absence of the former now implies the latter.

In the process, we removed some features 735 of the language since it was too flexible: 736 * Semicolons are no longer valid at the end of lines 737 * Keys cannot be double-quoted strings: `"foo" = "bar"` is no longer 738 valid. 739 * JSON style maps `{ "foo": "bar" }` are no longer valid outside of JSON. 740 Maps must be in the format of `{ foo = "bar" }` (like other objects 741 in the config) 742 * Heroku apps now require (will not validate without) `region` and 743 `name` due to an upstream API change.
