Hi @giajh01 Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.
The link Azure RTOS 6.3.0 release gives you all the details of the files that has been modified for this release. If you take a look at the changes made, they are a total of 145 files modified addressing different issues. It would be hard to provide more information on which specific code changes were made to address the specific issue you pointed in the question.
However, if you compare the 6.3.0 release version to a previous version such as 6.2.1, you will get the details on all the code changes made to the 6.3.0 version. Please refer the following link Comparing changes 6.2.1 vs 6.3.0 to view these changes. Hope this helps! Let us know if you still need any additional assistance on this.
