 - Optionally create custom Lambda Layer zip using [build-lambda-layer-python](https://github.com/robertpeteuil/build-lambda-layer-python)
   - Enables adding/changing dependencies
   - Enables compiling for different version of Python
-- New behavior in `3.0.0` in preperation for Terraform 0.13
-  - inherits `region` from calling module's AWS Provider for resource creation/discovery.
-  - Deploy to alternate regions via provider aliases and [expicit provider passing](https://www.terraform.io/docs/configuration/modules.html#passing-providers-explicitly)
-- This is driven by new recommendations for [Provider Configurations in Modules with 0.13](https://github.com/hashicorp/terraform/blob/master/website/docs/configuration/modules.html.md#providers-within-modules)

+- **Breaking Changes** in `3.0.0` - required to enable new Terraform 0.13 module arguments `for_each`, `count`, and `depends_on`
+  - The module's internal AWS `provider` block has been removed
+  - `var.aws_region` has been removed and can't be used to set a target region
+  - By default, modules inherit the `region` of the calling module's Provider
+  - To specify alternate regions, use provider aliases and [expicit provider passing](https://www.terraform.io/docs/configuration/modules.html#passing-providers-explicitly)
