I should add I have only been using Roon since late 2020.
Also in playing with Release Date in 1.8 I don’t see a way to just set a cutoff time for Release Date either. Say, Include 2000s, 2010s, 2020s (let alone granularity beyond decades…).
Someone who seems to have found a similar issue in 1.7 a year ago with date added UI weirdness. Except back then you could choose release dates more granularly.
