+## 4.28.0
+**`(feat):`** Add `coerce-consts-to` setting for controlling how OpenAPI/AsyncAPI
+`const` values are represented. Set to `literals` to convert them directly
+to literals with defaults; set to `enums` (the default, current behavior)
+to convert them to single-valued and therefore extensible enums.
+
+When `coerce-consts-to` is `enums`, the `coerce-enums-to-literals` setting
+will not transitively apply to const-originated enums, keeping the two
+concepts independent.
+
+Usage:
+```yaml
+api:
+  specs:
+    - asyncapi: ./asyncapi.yaml
+      settings:
+        coerce-consts-to: literals
+```

+**`(fix):`** Fix non-deterministic ordering in generated requests.go and requests_test.go.
+Go maps randomize iteration order, causing type ordering to vary across runs
+when exportAllRequestsAtRoot is enabled. Map keys are now sorted before
+iteration to ensure deterministic output.
