## 2.17.3

**`(fix):`** Gracefully handle null values in docs.yml structure.

## 2.17.2

**`(fix):`** Escape `$` when inferring examples from literals that start with `$`.
This fixes validation issues like `Example $ending is malformed. Examples should be formatted like $YourType.ExampleName`.

## 2.17.1

**`(fix):`** Fix file scope type resolution for inline request properties

## 2.17.0

**`(feat):`** Add `substitute-env-vars` flag to `docs.yml` settings configuration. When set to `true`,
environment variables using `${VAR_NAME}` syntax are substituted across all files in the docs bundle,

Use `\$\{VAR\}` to escape and output literal `${VAR}` without substitution.

## 2.16.0

**`(feat):`** Add support for aliases in generators.yml. You can now define aliases that map to multiple groups, allowing you to run multiple groups with a single command.
