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 numberversionBase, the version it is based onbuildTime, 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.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is unclear whether the version and build time describe the runtime Claude Code runs on or the Claude Code build itself.
