Release Notes

cloudposse/terraform-null-label

### [`v0.25.0`](https://togithub.com/cloudposse/terraform-null-label/releases/0.25.0) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.24.1...0.25.0)

Add "tenant", "labels_as_tags", and "descriptors" @​Nuru (#​132)

#### what - Add additional label and `id` component: `tenant` - New input `labels_as_tags` controls which labels are exported as tags - New input `descriptor_formats` generates new output `descriptors` - Update README, remove link to obsolete `terraform-terraform-label` #### why - Support users that host resources on behalf of and/or dedicated to single customers - Supersedes and closes #​131, giving people control over which tags the module generates - Simple mechanism for creating multiple identifiers from the same inputs, reducing the need to create multiple instances of `null-label` - Document `tenant`, `labels_as_tags`, `descriptor_formats`, add additional clarification, stop promoting obsolete module

Fix: Update README Snippets @​korenyoni (#​130)

#### what * Update README snippets to reflect use of Terraform Registry. #### why * Including snippets that reflect use of the Terraform Registry make it easier for users to quickly instantiate a null_label module. * README is out of date and does not include snippets that reflect use of the Terraform Registry. #### references * N/A

Bridgecrew compliance @​Nuru (#​125)

#### what - Resolve Bridgecrew compliance complaint about example Autoscaling Group (BC_AWS_GENERAL_31) - Fix typo in README - Include Terraform lock file in `.gitignore` #### why - Get clean Bridgecrew badge - Correct confusing error - Ensure lock files are not checked into GitHub #### note The PR can and should be merged into `master` to update README and Bridgecrew without triggering a new release/version. These changes have no effect on the actual module in use and a release will create unnecessary ripple effects. However, merging to `master` will update the README and badges, so is worthwhile, and the changes will move forward into the next release.
