-## [3.0.0] - 2026-01-08
-
-### Breaking Changes
-
-- **BREAKING**: Removed `licenseKey` config option - use `clientId` and `clientSecret` instead
-- **BREAKING**: Removed `X-License-Key` header support - SDK now uses only OAuth2 Basic auth
-- **BREAKING**: `clientId` and `clientSecret` are now required for all enterprise features
+## [2.2.0] - 2026-01-08
 
 ### Added
 
+- **OAuth2-style client credentials**: New `clientId()` and `clientSecret()` builder methods following OAuth2 client credentials pattern.
+  - `clientId` is used for request identification (required for most API calls)
+  - `clientSecret` is optional - community/self-hosted deployments work without it
+
 - **Enterprise: Close PR** (`closePR`): Close a PR without merging and optionally delete the branch
   - Useful for cleaning up test/demo PRs created by code governance examples
   - Supports all Git providers: GitHub, GitLab, Bitbucket
   - Requires enterprise portal authentication
-- **PRRecord.closedAt**: Added optional `closedAt` field to track when a PR was closed
 
 ### Changed
 
-- **OAuth2-Only Authentication**: Simplified authentication to use only OAuth2 Basic auth
-  - Uses `Authorization: Basic base64(clientId:clientSecret)` header
-  - Removed `X-License-Key` and non-standard `X-Client-ID`/`X-Client-Secret` headers
-  - Aligns with industry-standard OAuth2 client credentials pattern
-
-### Fixed
+- **Simplified authentication**: For community mode, simply provide `clientId` for request identification. No `clientSecret` needed.
 
-- **getPlanStatus endpoint**: Fixed endpoint path from `/api/v1/orchestrator/plan/{id}` to `/api/v1/plan/{id}` to match agent proxy routes
-
-### Migration Guide
-
-**Before (v2.x):**
 ```java
-AxonFlowConfig config = AxonFlowConfig.builder()
+// Community mode - no secret needed
+AxonFlowClient client = AxonFlowClient.builder()
     .endpoint("http://localhost:8080")
-    .licenseKey("AXON-V2-...")
+    .clientId("my-app")  // Used for request identification
     .build();
 ```
 
-**After (v3.0.0):**
-```java
-AxonFlowConfig config = AxonFlowConfig.builder()
-    .endpoint("http://localhost:8080")
-    .clientId("my-client-id")
-    .clientSecret("my-client-secret")
-    .build();
-```
+### Fixed
+
+- **getPlanStatus endpoint**: Fixed endpoint path from `/api/v1/orchestrator/plan/{id}` to `/api/v1/plan/{id}` to match agent proxy routes
+
+### Enterprise
+
+- OAuth2 Basic auth: `Authorization: Basic base64(clientId:clientSecret)` replaces `X-License-Key` header
+- Removed `licenseKey()` builder method (use `clientId()`/`clientSecret()`)
