+## [v3.0.0] - 2026-07-01
+### Breaking Changes
+- **Module import path** — The Go module path has changed from `github.com/VapiAI/server-sdk-go/v2` to `github.com/VapiAI/server-sdk-go`. All import paths in your code must be updated to drop the `/v2` suffix (e.g. `github.com/VapiAI/server-sdk-go/v2/calls` → `github.com/VapiAI/server-sdk-go/calls`).
+- **`User-Agent` header** — The `User-Agent` HTTP header is no longer set by the SDK's `RequestOptions`. If your server-side code relied on this header being present, you will need to set it manually via a custom request option.
+
 ## v2.0.0 - 2026-06-24
 ### Breaking Changes
 * **`CartesiaExperimentalControlsSpeedZero`** has been renamed to **`CartesiaSpeedControlZero`**. The struct field `CartesiaSpeedControl.CartesiaExperimentalControlsSpeedZero`, accessor `GetCartesiaExperimentalControlsSpeedZero()`, visitor interface method `VisitCartesiaExperimentalControlsSpeedZero()`, all speed constants (`CartesiaExperimentalControlsSpeedZero*`), and `NewCartesiaExperimentalControlsSpeedZeroFromString()` have all been renamed to their `CartesiaSpeedControlZero`-prefixed equivalents. Update all references to use the new names.
