Hi Chengen, Thanks for your work on this bug / fix / SRU template!
Some process review notes: In the future, please update the bug tasks for the newer/devel releases as well. In this case, Mantic not marked as Won't Fix possibly would require you an extra round-trip during the review with the SRU team later, to clarify why it is affected but not being fixed. I think this is because Mantic will EOL in less than a month, thus not worth fixing. This type of information is helpful to add in the SRU template's Other Info section [1]. Please also see See SRU -> General Requirements > Newer Releases > Exceptions > "2."
