rom/miniz.h error still occurs when compiling for Core with board def 3.2.x

teastain

Only since the board def "updated" automatically from ver 2.1.4 to ver 3.2.x, I cannot compile my trusty, dusty Core Basic (Or Core2).

/Arduino/libraries/M5Stack/src/utility/pngle.c:31:10: fatal error: rom/miniz.h: No such file or directory

If I downgrade to 2.1.x it compiles as usual for 5 years running.

I found this on google and there have been some other reports on this very community site.

My Arduino IDE ver2.3.6 asks me EVERY DAY to upgrade to M5Stack board def 3.2.x.
This is getting tedious. Ver 3.2.1 recently added did not help.

Is M5Stack abandoning the older Cores?
