+## HIP 6.2 (For ROCm 6.2)
+
+### Added
+- Introduced the `_sync()` version of crosslane builtins such as `shfl_sync()`, `__all_sync()`
+  and `__any_sync()`. These take a 64-bit integer as an explicit mask argument.
+  - In HIP 6.2, these are hidden behind the preprocessor macro
+    `HIP_ENABLE_WARP_SYNC_BUILTINS`, and will be enabled unconditionally in HIP 6.3.
