Entrian Source Search 1.3.9 introduces a “Force index refresh” command. This isn’t necessary for most people because Source Search automatically re-indexes changed files as soon as they hit the disk, but some users whose source files are held on network drives have found that changes aren’t always picked up. (Thanks, Christian.)
Exclusion patterns are now case insensitive (thanks, Ike).
You can download 1.3.9 from the usual place.
