OpenHarmony 3.2.1 Release provides the following enhancements over OpenHarmony 3.2 Release:
According to security compliance requirements, UUIDs are used only for system applications and SAs, no longer for common applications. New UUIDs (sha256(appId_uuid)) that can be used by common applications are used in distributed data management.

| Issue No.| Description| Impact| To Be Resolved By|
| -------- | -------- | -------- | -------- |
| I6B4U3 | There is a low probability (3/10) that app freezing occurs in the com.ohos.launcher process.| When a large number of applications are installed (more than 40 applications) and the memory is small, there is a low probability that app freezing occurs. However, the home screen functions are normal and the overall functions and usage are not affected.| 2023-06-15|
| I6SXBI | There is a low probability that libdistributeddata.z.so in the ohos.samples.distributedcalc process causes a C++ crash.| When a user exits the Calculator application within 1 second after opening it, the JS object is destructed before it is successfully read from the database. An error is recorded in the log, but the user is unaware of the error. The impact is controllable.| 2023-07-15|
| I6TRE6 | There is a low probability that libdatashare_consumer.z.so crashes due to the com.ohos.contacts thread in the com.ohos.contacts process.| When a user exits the Contacts application within 600 ms after opening it, there is a low probability that the contacts process crashes. The contacts process will be automatically restarted after the crash. The impact is controllable.| 2023-07-15|
| I6SMQA | When a user uses a browser application to open a WeiBo page and swipes the screen quickly, jitter occurs during swiping.| The content is not loaded during swiping but will be loaded quickly. User experience is affected.| 2023-06-15|
| I72P5E | Memory leakage occurs in libace.z.so when a user touches an image in Gallery to maximize it and then exits repeatedly.| Each time the user touches an image in Gallery to maximize it and then exits, 10 KB memory of the ArkUI module leaks. When the user touches Back on the application, the leak issue disappears. The impact is controllable.| 2023-07-15|
| I72P5I | Memory leakage occurs in libace.z.so when a user touches an image folder in Gallery to browse images in grid form and then exits repeatedly.| Each time the user touches an image folder in Gallery to browse images in grid form and then exits, 19 KB memory of the ArkUI module leaks. When the user touches Back on the application, the leak issue disappears. The impact is controllable.| 2023-07-15|
| I76N0Y | Memory leakage occurs in libace.z.so when applications are repeatedly added to or removed from the dock bar.| Each time a widget is moved to a valid area, 99 KB memory of the ArkUI module leaks. This operation scenario is uncommon, and the leak issue disappears after the application is restarted. The impact is controllable.| 2023-07-15|
| I6XHE7 | Memory leakage occurs on the NAPIRemoteObject module.| When the JS application calls the IPC, the NAPIRemoteObject process needs to be created, and 1.2 KB memory occurs during the creation. However, the process can be used repeatedly once created, and the memory is released when the application process exits.| 2023-07-15|
