Thank you very much for the comment! Could you elaborate on which functions did not work in version 10.0 (alternatively, how you found out), and what was the glitching in the documentation?

I will see to the other things you mentioned immediately.

I have found that the auto-complete code also works with version 10.0, as you say, but if I have Get["MaXrd`Core`AutoComplete`"] in the MaXrd/Kernel/init.m file and the package is loaded on startup with

<< MaXrd`

in the Mathematica/Kernel/init.m file, there will either be error messages or other functions will break. For instance, calling $MaXrdChangelog will give the error: LinkOpen::linke: Specified file is not a MathLink executable..

Regarding the glitches in the documentation: When building the documentation with Mathematica 11.3 it creates boxes such as TemplateBox[{6}, "Spacer1"] which seem to be new to that version. I have found that building the package/documentation with an earlier Mathematica version in Eclipse (through the Wolfram Engine Installations in Preferences), the result will be fine.

Finally, it seems the lowest compatible version is 10.3. I had made use of functions such as StringContainsQ and UpTo which were “too new”.

Thank you again for the useful feedback!
