Since which LibreOffice Calc versions are the spreadsheet functions available?

Could you kindly help me find information about the spreadsheet functions in LibreOffice in regards of since which version of LibreOffice are they available? Thank you.

Take a look at … guess what … related help pages. E.g., for SUMIFS.

Actually it doesn’t help, check out this function’s page: WEBSERVICE - LibreOffice Help

Meanwhile I have found more up-to-date help pages for the same function, so the problem must have been that several help pages are available for the same function and some of them does not mention any version info.

4.4??? I even gave you the address with actual help. So you could likely type WEBSERVICE into Index search box on that page, and get to this page:

And by the way, the old help pages have this header:
