What
Claude Code now allows more environment variables through to itself:
HOMEDRIVE,HOMEPATH, andPROGRAMDATA, which help resolve credential and config paths on WindowsCCR_ENABLE_BUNDLE,CCR_FORCE_BUNDLE, andCLAUDE_CODE_DIR_SYNC_CHAIN, alongside existing directory-sync and legacy-bundle variables
CCR_FORCE_BUNDLE is documented as forcing claude --cloud to bundle and upload your local repository instead of cloning it from its remote.
Why
The Windows-specific variables improve how Claude Code finds config and credential paths on Windows. The CCR_* variables continue to support remote "teleport" sessions that seed a remote workspace from a local git bundle.
