Question about AIR-7503 with iOS Memory Warning fix

[FliplineStudios]

I just noticed the 51.1.3.2 release added a fix for AIR-7503 related to crashing with iOS memory warnings. I was just curious if anyone knows when the crash that is aiming to fix was first introduced?

Looking through our crash reports for our live apps in XCode Organizer, I've noticed our apps over the past couple years show a bunch of crashes that seem to be related to memory warnings, at least that's what I'm assuming these logs are showing, with things like:

Thread 0:
0 - Game Name - 0x102c64000 (or similar)
1 - UIKitCore - -[UIApplication _performMemoryWarning]
2 - UIKitCore - -[UIApplication _receivedMemoryNotification]
etc.

It seems like this started with our apps packaged with 33.1.1.345 (through our latest with 50.2.4.4). Earlier apps packaged with 33.1.1.63 and 32.x have never crashed from memory warnings.

Just curious if the fix for AIR-7503 was related to something that was introduced post 33.1.1.63, and if this would indeed clear up those crashes we're seeing in our newer apps?

I've attached a variety of these memory warning crashes we're seeing for reference, though I have multiple other examples. I believe I've correctly labeled each with the version of AIR that was used to package it, the ones for 50.2.4.4 would have been packaged on a Mac recently, and the older ones would have been packaged on a PC years ago. I've looked through the crashes for our other apps, and don't see any _performMemoryWarning crashes for ones packaged with 33.1.1.63 or earlier (32.0).
