What's new in TeX, part 1

My wife switched to LaTeX sometime in the mid-2000s. Yes, it is mostly about specific requirements: she is a linguist and their linguistic trees are just such pain to do in Word, that LaTeX was the only option for her. Also, even for my sociology thesis, LaTeX was the best option. There was not that much math, but working with large bibliographies and citations, was just such pain in Word/LibreOffice (then OpenOffice). Perhaps Zotero now makes life easier even for the Word users, but I have never seen the reason to switch back (although, now I write mostly in rST).
