-### OpenAPI 3.2.x ⏳
-- **Status:** Not yet released
-- **ETA:** Future (as of April 2026)
-- **Planned Support:** When OpenAPI 3.2 is officially released and swagger-parser is updated
-- **Expected Changes:** Refinements to JSON Schema integration, possible webhooks improvements
+### OpenAPI 3.2.x ✅
+- **Status:** Officially released and supported
+- **Release:** OpenAPI 3.2.0 (September 2025)
+- **Parser:** swagger-parser 2.1.41+ (current project version)
+- **Current Compatibility:** Parsed and generated through project-level normalization of 3.2-specific fields
+- **Highlights:** Additional HTTP method support, richer parameter modeling, and improved response metadata
 
 ## Version Detection
 
 The OpenAPI version is automatically detected from the `openapi` field in your spec:
 
 ```yaml
-openapi: 3.1.0  # Detected and handled appropriately
+openapi: 3.2.0  # Detected and handled appropriately
 ```
 
 No configuration is needed — just submit your spec and the tool will parse it correctly.
 
 ## Feature Compatibility Across Versions
