1What the notes say

Seedance has no dated release notes on the pages read. BytePlus's model list gives one row per version with its duration range, resolution and inputs, so the version steps are clear, 2 to 12 seconds on 1.0 Pro, 4 to 15 seconds and 4K on 2.0, 4 to 30 seconds on 2.5, but their days are not. The dates here come from Runway, Higgsfield and Luma announcing each version on their platforms, from April 2026 on.
