Counts per year: 2024 = 60, 2025 = 71, 2026 = 66, 2027 = 78 (FOSDEM says 77 of 128 proposals accepted; /dev/random, its own lightning-talk room, is likely the difference). Lightning talks are included as /dev/random; main tracks, BOFs and Junior are excluded. Rows marked “cf.” are related rooms with a different scope, kept separate. Sources: 2027, 2026, 2025, 2024.
