 ### Upgrade Overview
-The `Libraries-Bom` and its managed libraries have been upgraded to use **Protobuf v4.33.2**. All Protobuf gen code included in the managed libraries has been regenerated using `protoc v33.2`. Please note that this update necessitates a minimum Protobuf runtime of **v4.33.2**.

 ### ✅ Backward Compatibility
-The new protobuf-java v4.33.2 runtime is fully backward-compatible with protoc gen code 3.x. You should not experience any runtime incompatibilities from using older gen code with the new runtime.
-If you encounter any compatibility issues after this upgrade, please create an issue in our [GitHub repository](https://github.com/googleapis/sdk-platform-java/tree/main) or contact our support team through the [support console](https://cloud.google.com/support-hub) for assistance.

 While rare, the following incompatibilities may occur due to the version update:
 
 #### 1. Runtime Version Mismatch
-* **Issue:** The minimum required `protobuf-java` runtime version is now **v4.33.2**. Starting with the 4.x runtime, [validations](https://github.com/protocolbuffers/protobuf/blob/1082da2da37a0887d0cfd70abf4a00e8973cd8bf/java/core/src/main/java/com/google/protobuf/RuntimeVersion.java#L55-L73) ensure the runtime version is higher than the gen code version.
+* **Issue:** The minimum required `protobuf-java` runtime version is now **v4.33.2**. Starting with the 4.x runtime, [validations](https://github.com/protocolbuffers/protobuf/blob/1082da2da37a0887d0cfd70abf4a00e8973cd8bf/java/core/src/main/java/com/google/protobuf/RuntimeVersion.java#L55-L73) ensure the runtime version is higher than the gen code version. Using a lower version of protobuf-java will produce errors below.
 * **Symptoms:**
     * `java.lang.NoClassDefFoundError: com/google/protobuf/RuntimeVersion$RuntimeDomain` (when using 3.x versions).
     * `com.google.protobuf.RuntimeVersion$ProtobufRuntimeVersionException` (when using older 4.x versions).
-* **Mitigation:** Upgrade `protobuf-java` to **v4.33.2**.
+* **Mitigation:** Upgrade the version of `protobuf-java` to be greater than or equal to **v4.33.2**.
 
 #### 2. Class Hierarchy Changes (`GeneratedMessageV3`)
 * **Issue:** `GeneratedMessageV3` is no longer a parent class of gen code.
-* **Symptoms:** Runtime errors will occur if attempting to cast Proto 4.x gen code to `GeneratedMessageV3`. For example, `DeleteInstanceRequest` now extends [GeneratedMessage](https://github.com/googleapis/google-cloud-java/blob/d7a49aa9502012df1209b55ec741b1d4ac639361/java-compute/proto-google-cloud-compute-v1/src/main/java/com/google/cloud/compute/v1/DeleteInstanceRequest.java#L33) instead of [GeneratedMessageV3](https://github.com/googleapis/google-cloud-java/blob/1b56d017b4f93b5037f7261c488e008ac59897d8/java-compute/proto-google-cloud-compute-v1/src/main/java/com/google/cloud/compute/v1/DeleteInstanceRequest.java#L31).
+* **Symptoms:** Runtime errors will occur if attempting to cast Proto 4.x gen code to `GeneratedMessageV3`. For example, `DeleteInstanceRequest` now extends [GeneratedMessage](https://github.com/googleapis/google-cloud-java/blob/d7a49aa9502012df1209b55ec741b1d4ac639361/java-compute/proto-google-cloud-compute-v1/src/main/java/com/google/cloud/compute/v1/DeleteInstanceRequest.java#L33) instead of [GeneratedMessageV3](https://github.com/googleapis/google-cloud-java/blob/1b56d017b4f93b5037f7261c488e008ac59897d8/java-compute/proto-google-cloud-compute-v1/src/main/java/com/google/cloud/compute/v1/DeleteInstanceRequest.java#L31). You will run into `java.lang.ClassCastException` when trying to run `(GeneratedMessageV3)DeleteInstanceRequest`.
 * **Mitigation:** Migrate usages of `GeneratedMessageV3` to its parent interface, `Message`.
 
 #### 3. Descriptor Syntax APIs
 * **Issue:** Certain internal methods in [Descriptors](https://github.com/protocolbuffers/protobuf/commit/1aeacd4f4eb4e0aa05d6336e2988a565e475e9a0) are no longer available.
+* **Symptoms:** `java.lang.NoSuchMethodError` when calling `Syntax`, `getSyntax()`, `hasOptionalKeyword()` or `isSynthetic()`.
 * **Mitigation:** There are no direct alternative methods; it is suggested to stop using them.
 
 #### 4. Legacy Generated Code (v2.x)
