Unclear It is unclear whether the version and build time describe the runtime Claude Code runs on or the Claude Code build itself.

What

Claude Code sends some information about the environment it runs in along with its usage and diagnostic data. That information now includes three more fields:

  • version, a version number
  • versionBase, the version it is based on
  • buildTime, when it was built
Why

Crash reports and usage data can now be tied to an exact build, which helps when working out which builds a problem affects.
