What's different from the standard sv_SE?

The standard sv_SE.dic shipping with most Linux distros and LibreOffice is from 2016–2017. This dictionary:

1. Starts from SFOL 2.42 (2020) — 1 500+ more words than the distro version
2. Adds SALDO + SALDOM — 35 000+ words from Språkbanken with proper affix paradigms
3. Adds 12 000+ words from TM — real words used in Swedish software translations
4. Improves compound support — better handling of Swedish compound words
5. Includes modern terminology — IT, social media, climate, and tech terms from SAOL 15
