0.3.7 (unreleased)

FEATURES:

• New provider: azure - initially just supporting Linux virtual machines [GH-899]

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]

• provider/aws: Support the more standard environmental variable names for access key and secret keys. [GH-851]
• provider/aws: The aws_db_instance resource no longer requires both 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]
• provider/google: Remove "client secrets file", as it's no longer necessary for API authentication [GH-884].

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.
