What's New in Longbox
1.0.6
October 17, 2026
Your server library fills in its own publishers now. Longbox works out the publisher for every series on your Komga or Kavita server in the background, so Smart Lists, the publisher view and search work across your whole collection — not just the comics you've opened. More comics find their details, too: series named like "Batman Vol 1", and team-ups the database spells with "&", such as "The Atom & Hawkman". Spider-Man, X-Men and other hyphenated comics that couldn't find theirs before the last update get another try. Fixed • Smart Lists now include your server comics, and the count on the card matches what's inside • Enrich Missing Metadata works on server libraries, and tells you what it found • If you reach the daily metadata limit, Longbox tells you when lookups pick up again instead of just stopping
