Release Notes

cloudposse/terraform-aws-security-group

### [`v0.4.3`](https://togithub.com/cloudposse/terraform-aws-security-group/releases/0.4.3) [Compare Source](https://togithub.com/cloudposse/terraform-aws-security-group/compare/0.4.2...0.4.3)

Update recommended inputs and outputs @​Nuru (#​26)

#### what - Update recommended inputs and outputs #### why - Changes based on experience implementing several modules

#### 🚀 Enhancements

Rename the exported `security_group_inputs.tf` file to `security-group-inputs.tf` @​aknysh (#​30)

#### what * Rename the exported `security_group_inputs.tf` file to `security-group-inputs.tf` * Update GitHub workflows and LICENSE #### why * Our naming convention is to use `kebab-case` for all files. Having a file in `snake_case` (after adding it to a repo) together with all the other files in `kebab-case` in the same repo does not look correct * Keep up to date
