 # Changelog for ROCm Systems Profiler
 
 Full documentation for ROCm Systems Profiler is available at [https://rocm.docs.amd.com/projects/rocprofiler-systems/en/latest/](https://rocm.docs.amd.com/projects/rocprofiler-systems/en/latest/).
 
+## ROCm Systems Profiler 1.2.0 for ROCm 7.1
+
+### Added
+
+- ``ROCPROFSYS_ROCM_GROUP_BY_QUEUE`` configuration setting to allow grouping of events by hardware queue, instead of the default grouping.
+- Support for rocPD database output with the `ROCPROFSYS_USE_ROCPD` configuration setting.
+
+## Changed
+
+- Updated the grouping of "kernel dispatch" and "memory copy" events in Perfetto traces. They are now grouped together by HIP Stream rather than separately and by hardware queue.
