## 0.4.0 (unreleased)
IMPROVEMENTS:
* **New config function: `split`** - Split a value based on a delimiter.
This is useful for faking lists as parameters to modules.
BUG FIXES:
* core: module outputs can be used as inputs to other modules [GH-822]
* core: Self-referencing splat variables are no longer allowed in
provisioners. [GH-795][GH-868]
* core: Validate that `depends_on` doesn't contain interpolations. [GH-1015]
* core: Module inputs can be non-strings. [GH-819]
* providers/aws: manually deleted VPC removes it from the state
* providers/aws: `source_dest_check` regression fixed (now works). [GH-1020]
## 0.3.7 (February 19, 2015)
IMPROVEMENTS:
* **New resources: `google_compute_forwarding_rule`, `google_compute_http_health_check`,
and `google_compute_target_pool`** - Together these provide network-level
load balancing. [GH-588]

for access key and secret keys. [GH-851]

`final_snapshot_identifier` and `skip_final_snapshot`; the presence or
absence of the former now implies the latter. [GH-874]
* provider/aws: Avoid unecessary update of `aws_subnet` when
`map_public_ip_on_launch` is not specified in config. [GH-898]

for API authentication [GH-884].
* provider/google: Expose `self_link` on `google_compute_instance` [GH-906]
BUG FIXES:
* core: Fixing use of remote state with plan files. [GH-741]
* core: Fix a panic case when certain invalid types were used in
the configuration. [GH-691]
* core: Escape characters `\"`, `\n`, and `\\` now work in interpolations.

to remove it. [GH-952]
* core: Bare "splat" variables are not allowed in provisioners. [GH-636]
* core: Invalid configuration keys to sub-resources are now errors. [GH-740]
* command/apply: Won't try to initialize modules in some cases when
no arguments are given. [GH-780]
* command/apply: Fix regression where user variables weren't asked [GH-736]
* helper/hashcode: Update `hash.String()` to always return a positive index.
Fixes issue where specific strings would convert to a negative index
and be ommited when creating Route53 records. [GH-967]

* provider/aws: No read error when subnet is manually deleted. [GH-889]
* provider/aws: Tags with empty values (empty string) are properly
managed. [GH-968]
* provider/aws: Fix case where route table would delete its routes
on an unrelated change. [GH-990]
* provider/google: Fix bug preventing instances with metadata from being
created [GH-884].
PLUGIN CHANGES:
* New `helper/schema` type: `TypeFloat` [GH-594]
* New `helper/schema` field for resources: `Exists` must point to a function
to check for the existence of a resource. This is used to properly
handle the case where the resource was manually deleted. [GH-766]
* There is a semantic change in `GetOk` where it will return `true` if
there is any value in the diff that is _non-zero_. Before, it would
return true only if there was a value in the diff.

* provider/aws: `availability_zones` on ELB will contain more than one
AZ if it is set as such. [GH-682]

## 0.3.0 (October 14, 2014)
FEATURES:
* **Modules**: Configuration can now be modularized. Modules can live on
GitHub, BitBucket, Git/Hg repos, HTTP URLs, and file paths. Terraform
automatically downloads/updates modules for you on request.

infrastructure from a module.
* The state file format is now JSON rather than binary. This allows for
easier machine and human read/write. Old binary state files will be
automatically upgraded.

variables).

data.
* providers/aws: ELB works properly with dynamically changing
count of instances.

in the config)

to the user's home directory. [GH-179]

* 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]

operation is in progress [GH-183]

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.
