+### Glob Coverage Thresholds No Longer Inherit `perFile`

+`coverage.thresholds.perFile` previously applied to every threshold set, including files matched by glob-pattern thresholds. Glob patterns now control their own per-file checking and no longer inherit the top-level `perFile` — set `perFile` on each glob that needs it.

 ### Config Files Are Not Looked Up From Parent Directories
 
 Vitest no longer searches parent directories for config files. If you previously relied on running `vitest` from a subdirectory while using a config file from a parent directory, pass the config explicitly and scope test discovery with `--dir`. For example,
