Message while compiling is unclear to me

While compiling a simple sketch, I get this message:

Warning: platform.txt from core 'SODAQ SAMD (32-bits ARM Cortex-M0+) Boards’contains depricated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" … and a lot more txt.

Then the IDE says that compiling is OK.

What is it about and do I have to do something to get rid of this warning?

You can ignore this warning. It has no effect on the compiling process.

A fix has been added and it will be rolled out with the next update of the board files.

Thanks for the quick response.
