   *     Babelstream updates to support FORTRAN babelstream.
   *
   * 19.0-0
+  *   Now use ROCM 6.0.2 sources for non compiler components.
+  *   Default to not use multiple SDMA engines.  This could be changed for testing
+  *     by setting: LIBOMPTARGET_AMDGPU_USE_MULTIPLE_SDMA_ENGINES=true
+  *   Updates to gpurun utility
+  *     - uses preset HSA_CU_MASK and ROCR_VISIBLE_DEVICES.
+  *   OpenMP lit testing pre-install, 100% pass rate.
+  *   [Perf] Implement the loop directive as used in the metadirective for spec.
+  *   Support for testing QMCpack NiO performance.
+  *   ROCgdb support for gfx1103.
+  *   Circumvented driver timing issue with complex signal chains. Post kernel
+  *     copies occasionally started before kernel completion.  The temporary fix
+  *     forces the wait for kernel completion before scheduling post-kernel copies.
+  *     For testing purposes, this behavior could be reverted by setting
+  *     LIBOMPTARGET_SYNC_COPY_BACK=false
+  *
+  *   Fix regressions:
+  *     #616 llvm-addr2line does not work on AOMP-generated binary.
