### [`v0.25.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/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 * README is out of date and does not include snippets that reflect use of the Terraform Registry.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.

Properly output descriptors of chained modules @​Nuru (#​133)

#### what - Properly output descriptors of chained modules #### why - Bug fix; implement intended behavior

### [`v0.24.1`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.24.1): Allow control of letter case of outputs [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.24.0...0.24.1)

Allow control of letter case of outputs @​SweetOps (#​107)

You now have control over the letter case of generated tag names and supplied labels, which means you also have control over the letter case of the ultimate `id`. Labels are the elements you can include in `label_order`, namely `namespace`, `environment`, `stage`, `name`, and `attributes`. For every non-empty label, a corresponding tag name is generated. For `namespace`, `environment`, `stage`, the output is the formatted, normalized input. (By "normalized" we mean that it goes through `regex_replace_chars`.), For `attributes`, which is a list, each element is normalized, duplicates are removed, and the resulting list is converted to a string by joining the elements with the `delimiter` (defaults to hyphen). For `name`, which is special, the output is the same as `id`, which is the joining of the labels in the order specified by `label_order` and separated by `delimiter`. - You can set `label_key_case` to one of `upper`, `lower`, or `title`, which will result in generated `tag` names in the corresponding case: `NAME`, `name`, or `Name`. For backwards compatibility, `title` is the default - You can set `label_value_case` to one of `upper`, `lower`, `title`, or `none`, which will result in output label values in the corresponding case (with `none` meaning no case conversion of any kind will be done, though the labels will still be subject to `regex_replace_chars`). The case converted labels will show up not just in the module output of the labels themselves, but also in the `tag` values and in the `id` string. You can look at the test cases in `examples/complete` and the expected results in `test/src/examples_complete_test.go` to see examples of how this is supposed to work. One interesting example is that you can create `id`s in Pascal case by setting `label_value_case = "title"` and `delimiter = ""`.

Include updates to exports/context.tf @​Nuru (#​122 and #​123)

#### what - Include updates to `exports/context.tf` - Update README with features and compatibilty - Add validation for `id_length_limit` #### why - The `exports/context.tf` is what gets distributed and needs to be in sync - Replace outdated information - Was not validated earlier because validators are not supported in TF 0.12 but now we are dropping support for TF 0.12 and so we can add validators

Restore backward compatibility with v0.22.1 and earlier @​Nuru (#​121)

#### what - Restore backward compatibility with v0.22.1 and earlier - Allow setting of `label_key_case` and `label_value_case` by vars, not just by context attributes. #### why - Allow interoperability of old and new modules - Normally, root modules make settings via individual variables, not by setting an entire context block. Incorporates and closes [#​120](https://togithub.com/cloudposse/terraform-null-label/issues/120)

##### 🐛 Bug fix/Breaking change This version introduced a bug fix that technically is a breaking change. The input `regex_replace_chars` specifies a regular expression, and characters matching it are removed from labels/id elements. Prior to this release, if the `delimiter` itself matched the regular expression, then the delimiter would be removed from the `attributes` portion of the `id`. This was not a problem for most users, since the default delimiter was `-` (dash) and the default regex allowed dashes, but if you customized the delimiter and/or regex, this could affect you. ### [`v0.24.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.24.0) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.23.0...0.24.0)

One interesting example is that you can create `id`s in Pascal case by setting `label_value_case = "title"` and `delimiter = ""`.

#### Known issues - `exports/context.tf` still not backwards compatible - Validation for `id_length` not included in `exports/context.tf` ### [`v0.23.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.23.0): pre-release: Allow control of letter case of outputs [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.22.1...0.23.0) #### Known issues - Does not interoperate with earlier versions of `null-label`. The canonical `context = module.this.context` fails if `module.this.context` is an older version - `context.tf` does not incorporate `var.label_key_case` and `var.label_value_case` into the `module.this` object, preventing those variables from taking effect in the root module's `module.this`.

Add var.attributes to end of context.attributes, not vice versa @​Nuru (#​114)

#### what - Add `var.attributes` to end of `context.attributes`, not vice versa - Update to current workflows (with some exceptions) #### why - Modules should append to attributes passed in, not insert themselves ahead of others - New features, like auto-format (but holding back some, because this is a special module) #### references - closes #​113 - closes #​108

Convert context.tf to registry reference @​Nuru (#​110)

#### what - Convert `context.tf` to use registry reference - Update version requirement to `>= 0.12.26` - Switch auto-publish to draft mode #### why - New standard way to reference modules - Minimum version that supports registry references - Ensure that version numbers are set manually and match what is in `context.tf`

Update `null-label` version used for exporting into other modules @​aknysh (#​106)

#### what * Update `null-label` version used for exporting into other modules #### why * New release will be made from this PR - use this release in `exports/context.tf` to be exported into other modules

Update versions.tf to support tf .14 @​kiddom-kq (#​105)

Adds support for Terraform `0..14` (currently in `beta2`) I've currently got it pinned to ` < 0.14.1 ` to be conservative. Can update to `< 0.15` or similar. #### what - Bumps `versions.tf` to support terraform `0.14` #### why - I make extensive use of this label module (it's an *amazing* contribution to the TF ecosystem. Thank you!) - I am currently running into an [unrelated](https://togithub.com/hashicorp/terraform/issues/26579) issue w/ TF `0.13`. The proposed workaround for that unrelated issue does not work for me at this time. - The solution is to use tf `0.14` which is in beta, now. #### references Fixes [https://github.com/cloudposse/terraform-null-label/issues/104](https://togithub.com/cloudposse/terraform-null-label/issues/104)

Remove symlink, polish documentation @​Nuru (#​101)

#### what - Replace symbolic link to `context.tf` (`examples/autoscalinggroup/context.tf`) with copy of file - Move module to top of `context.tf` and clean up documentation comments inside the file #### why - Terraform clones the whole repo, not just the top directory, and the symbolic link causes problems for some IDEs - Module contains version number and source URL, which should be at the top of the file

### [`v0.19.1`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.19.1) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.19.0...0.19.1)

Include all context inputs as normalized outputs @​Nuru (#​100)

##### Enhancement to #​99 #### what - Include all context inputs as normalized outputs #### why - Enable a consistent pattern of `module.this.context.var` to reference the input value with `null` defaults and `module.this.var` to reference the normalized value with nulls replaced by actual default values. #### references - See #​99: Standardize `context` for input and chaining

### [`v0.19.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.19.0) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.18.0...0.19.0)

Standardize `context` for input and chaining @​Nuru (#​99)

#### what - Refine the `context` object concept: - The previous `context` output contained normalized and generated data. This has now been renamed `normalized_context` - The new `context` object output simply propagates the input unmodified - The new `context.tf` file can be dropped into any module to provide standard context inputs and a context output (`module.this.context`) that can be fed into other modules - Refine the `id` length limit: - Rename `id_max_length` to `id_length_limit` - Prevent consecutive delimiters and at the same time ensure that if the `id` is truncated, it is truncate to exactly `id_length_limit` characters - Ensure that it is possible to eliminate delimiters by setting `delimiter = ""`. Closes #​77 - Add additional tests for all of the above. #### why - Provide a consistent interface to our modules, allow chaining, and provide something like a global setting as requested in [#​88](https://togithub.com/cloudposse/terraform-null-label/issues/88) - Make length limit for `id` more intuitive. Since `id` is also used as a tag value, and AWS limits tag value length to 255 characters, limit the `id` length by default so it will not break AWS. - Some environments do not allow non-alphabetic characters in names - Greater code coverage for testing helps prevent bugs from creeping in as new features are added

### [`v0.18.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.18.0): : Add id_max_length [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.17.0...0.18.0) This is a pre-release, to thank [@​tibbing](https://togithub.com/tibbing) for his contribution. There will be breaking changes to this feature in the next release. [#​98](https://togithub.com/cloudposse/terraform-null-label/issues/98) Thanks to [@​tibbing](https://togithub.com/tibbing) - Adds a new optional variable `id_max_length`, that when set to a value greater than 0 will limit the length of ID output to given value. - The truncated ID is still disambiguated by suffixing the first 5 characters of the md5 hash of the full ID. - The full ID will still be available as a new output `id_full`. - The default value of `id_max_length` is 0, so that the change is not breaking any existing usages. ### [`v0.17.0`](https://togithub.com/cloudposse/terraform-null-label/compare/0.16.0...0.17.0) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.16.0...0.17.0) ### [`v0.16.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.16.0): Removed unnecessary step for tags_as_list_of_maps [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.15.0...0.16.0) #### what -

The only case this actually applies to is the delimiter, which has a default value of '-', however all others changed to make them consistent. ### [`v0.5.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.5.0) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.4.1...0.5.0) #### what - Add new variable that allows for providing a `label_order` as a list to specify which variables and in what order go into the `id` output and `Name` tag. - The list can include all or none of the a variable names: `"namespace", "environment", "stage", "name", "attributes"` #### why Resolves [https://github.com/cloudposse/terraform-null-label/issues/35](https://togithub.com/cloudposse/terraform-null-label/issues/35) ### [`v0.4.1`](https://togithub.com/cloudposse/terraform-null-label/compare/0.4.0...0.4.1) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.4.0...0.4.1) ### [`v0.4.0`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.4.0): Context - Allows chaining label modules together [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.8...0.4.0) The module has a new `context` variable and output. The module has a new `environment` variable. The module now allows all variables to be optional and follows a set of rules to generate the outputs. Context allows the variables of one label module to be passed to the next label module. Allowing you to create one label that has the base set of values, and then creating every extra label as a derivative of that. The environment variable can be used with the stage variable or alone. It was added because in some businesses the term `environment` is embedded as a "known term" for the separation of resources from development to production, so to keep this module from changing the embedded nomenclature this variable was added with backwards compatibility. ### [`v0.3.8`](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.7...0.3.8) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.7...0.3.8) ### [`v0.3.7`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.3.7): : Readme.yaml - fix avatars links [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.6...0.3.7) #### what - Remove home pages and avatars links #### why - Build-harness does it automatically ### [`v0.3.6`](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.5...0.3.6) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.5...0.3.6) ### [`v0.3.5`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.3.5) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.4...0.3.5) #### what - Update `README` - Fix make targets #### why - Some improvements and fixes - Use `/` instead of `:` in make targets ### [`v0.3.4`](https://togithub.com/cloudposse/terraform-null-label/releases/tag/0.3.4) [Compare Source](https://togithub.com/cloudposse/terraform-null-label/compare/0.3.3...0.3.4) #### what - Add support for list of tag maps #### why - Certain kinds of resources (e.g. AWS AutoScaling groups) need them
