I'm still scared every time I have to update something, so I try to avoid updates if possible.
Most of the time when I had to update Windows or some software, something would break (and no previous bug would be fixed) and I would have to spend a whole day trying to fix the stupid issue.
TBH, I don't even remember if an update ever fixed something for me (but it probably happened at least once).
I have written my CV in HTML, CSS, little bit of JavaScript and handlebars.js library (single JS file). I have all the texts inside JSON files (one file per language). I can switch between languages simply by changing a variable and refreshing the page.
When I need to update the CV, I just change the text and print the CV as a webpage into a PDF using an Ungoogled Chrome (Firefox has a bug that causes the page to print in a slightly wrong size).
It may be overkill for some, but for me it was easier to properly style the page using a CSS than using Writer/Word.
