What
A settings file can set environment variables, which are named values programs read when they start. Some variables cannot take their value from a settings file. When a settings file tries to set one of those, Claude Code now warns that no settings file can give it this value, only the environment Claude Code is started with or Claude Code itself. Before, it warned only for one particular group of variables.
Why
You now hear about it when Claude Code ignores a variable you put in a settings file, instead of having it silently not apply.
