Hello,

I would like to understand the differences between Apache POI version 3.17 =
and versions after 4.0.0. The reason for asking is that when an `.xlsx` fil=
e generated with versions after 4.0.0 is uploaded to Slack, it is not recog=
nized as an Excel file. However, files generated with version 3.17 are corr=
ectly recognized as Excel files. What could be causing this difference?

Thank you!
