<![CDATA[Cannot compile Core Basic or Core2 with M5Stack board def 3.20]]>After 'letting' Arduino IDE update a bunch of boards and libraries...
I cannot compile Core Basic or Core2 with M5Stack board def 3.20
I get;
fatal error: rom/miniz.h: No such file or directory

I updated every relevant file but the best fix was revert to M5Stack boards to ver 2.14
Therefore
3.20 was the problem.

The IDE is now asking me to update to ver 3.20!

I asked Chat.M5Stack and it was not helpful.
I contacted M5Stack support and they just told me the problem is mine...

Sorry, we are now fixing this problem. Please use 2.x temporarily, we will fix this problem in the future.

Add rom/miniz.h where it needs to be.
I try to keep my Arduino IDE setup up-to-date but now it reminds me that 3.20 is available and I may need it for newer Tab products?
We need customer support not frustrating answers.
Technically all of the Arduino IDE examples in YOUR M5Stack Github GitHub for Core and Core2 won't work.
e.g. https://github.com/m5stack/M5Core2/tree/master/examples
Are you saying that older M5Stack models are no longer supported?
