Claude Code v2.1.268 ·

Env-var telemetry allowlist and a no-op stub added near it

Telemetry now only logs recognized CLAUDE_CODE_/ANTHROPIC_ env var names by name, bucketing the rest as 'other'

What

A new allowlist of about 30 named CLAUDE_CODE_* and ANTHROPIC_* environment variables is now used when logging which environment variables are set: names on the list are reported as-is, while any other environment variable name is bucketed and logged simply as "other". An unrelated no-op function was added nearby in the same change but does nothing.

Why

This keeps diagnostics and telemetry from recording arbitrary, potentially sensitive environment variable names that happen to start with those prefixes, only known/expected variable names are reported individually.
