The Claude Code date is its first mention in the changelog. When that entry was not an “Added” one, the feature existed by that date at the latest, so the lag is a lower bound. Hatched: before we started tracking the other tool, when its earlier releases are unknown to us.

Share counts every changelog entry including fixes; the week in progress is left out. A language model assigns the topics, so single entries may be misfiled. A major change is one the model rated highest (a new capability or a breaking change). Weekly summaries of every tool are in Weekly updates.
