+# AMD ROCm™ v4.5.2 Release Notes 
+
+This document describes the features, fixed issues, and information about downloading and installing the AMD ROCm™ software. It also covers known issues and deprecations in this release.
+
+## INSTALLATION GUIDE UPDATES FOR ROCM V4.5.2 
+
+In this release, users have the option to install the kernel mode driver using the Installer method. Some of the ROCm-specific use cases that the installer currently supports are:    
+
+- OpenCL (ROCr/KFD based) runtime  
+
+- HIP runtimes  
+
+- ROCm libraries and applications  
+
+- ROCm Compiler and device libraries  
+
+- ROCr runtime and thunk  
+
+- Kernel mode driver  
+
+For more details, refer to the AMD ROCm Installation Guide v4.5.2 at, 
+
+https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation_new.html
+
+
+## HIP ENHANCEMENTS
+
+
+The ROCm v4.5.2 release consists of the following HIP enhancement. 
+
+### Changes to the roc-obj-ls Tool 
+
+The roc-obj-ls tool is corrected in ROCm v4.5.2, and the command roc-obj-ls <exe> | roc-obj-extract is no longer the preferred syntax.   
+
+Use the roc-obj tool with the following correct command:  
+
+```   
+
+        roc-obj <exe> 
+ 
+ ```   
+
+For example, 
+
+Extract all ROCm code objects from a list of executables 
+ 
+ ```   
+
+       roc-obj <executable>... 
+ 
+ ```   
+
+Extract all ROCm code objects from a list of executables, and disassemble them 
+ 
+ ```   
+
+       roc-obj --disassemble <executable>... 
+ 
+       # or 
+
+       roc-obj -d <executable>... 
+
+ ```   
+
+Extract all ROCm code objects from a list of executables into dir/ 
+ 
+ ```   
+
+       roc-obj --outdir dir/ <executable>... 
+
+       # or 
+
+       roc-obj -o dir/ <executable>... 
+
+ ```   
+
+Extract only ROCm code objects matching regex over Target ID 
+ 
+ ```   
+
+       roc-obj --target-id gfx9 <executable>... 
+
+        # or 
+
+       roc-obj -t gfx9 <executable>... 
+
+```    
+
+For more information, refer to the HIP Programming Guide at:  
+
+https://rocmdocs.amd.com/en/latest/Programming_Guides/Programming-Guides.html 
+
+
+ ## OPENMP DEFECT FIX
+
+Previously, ROCProfiler crashed when the following ROCProfiler options were used in OpenMP programs: 
+
+* --stats  
+
+* --hsa-trace 
+
+This issue is fixed in the OpenMP plugin by ensuring that the contents of a kernel dispatch packet are not accessed after publishing it. The issue is also fixed in ROCTracer by ensuring that the registered exit function is called before runtime library is closed.
