+Usually, patched versions of PowerShell have the same cmdlet data, therefore only settings of major and minor versions of PowerShell are supplied. One can also create a custom settings file as well with the [New-CommandDataFile.ps1](https://github.com/PowerShell/PSScriptAnalyzer/blob/development/Utils/New-CommandDataFile.ps1) script and use it by placing the created `JSON` into the `Settings` folder of the `PSScriptAnalyzer` module installation folder, then the `compatibility` parameter is just its file name (that can also be changed if desired).
+Note that the `core-6.0.2-*` files were removed in PSScriptAnalyzer 1.18 since PowerShell 6.0 reached it's end of life.
