Not individually listed upstream

v1.0.100 does not have its own entry in Anthropic’s official changelog, because prerelease builds are often folded into a neighbouring release. Browse the full changelog for the closest official notes. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

System prompt

The system prompt was not captured for this release, so this page cannot say whether it moved.
