Tip: Claude Code Integer Env Vars Now Accept Scientific and Underscore Notation (1e6, 64_000)

Claude Code Changelog·low signal

v2.1.211 updates integer environment variables to accept scientific notation, so `1e6` and `64_000` are valid where only `1000000` and `64000` worked before. Small change, real effect on config review: token and context budget values are the env vars most often misread by a digit, and a reviewer can check `64_000` at a glance. Also in this release, memory writes over the limit now raise an explicit error instead of silently truncating.
