Quarters: every dated entry, three months at a time
Each page lists the entries dated in one quarter across all lines, with what changed and a count by kind of change. As of 2026-09-25.
Undated version rows are not in any quarter.
Earlier quarters are thinner because fewer makers kept dated logs then. The first quarter comes from Runway's changelog alone and the second adds Kling's API log; from 2025 more makers publish dated notes, so later quarters are longer partly because more is written down.
Each quarter page counts its entries by kind of change, lists them in date order and names the lines that had entries, with links to the quarters on either side.

2Using the models, not reading about them
Release notes such as “Quarters” matter once a pipeline runs the models; SceneMixer's guides describe how it does:
Each segment is generated on whatever tier was selected at the time, and the episode composites them together.
