If you don’t want to use Microsoft’s quasi-standard, but prefer a free office solution, you will most likely use LibreOffice. There is now a new version of this: 7.5.
This brings a few improvements: in Calc now diagrams can be inserted and translations can be created automatically via DeepL connection. Also nice: the dark mode has been improved and the start center has been slightly reworked.
If you are using an old Mac, watch out: The 7.5 version of LibreOffice requires at least macOS 10.14. If you are on 10.13 at most, the last installable version of LibreOffice is 7.4.5.
