Version 1.4 of the Savage Rifts files are now available through the update mechanism.
Because this includes the Generic Racial Tab, you may want to add the update link found
in this post for that specifically as well.
I'm hoping it's showing as a new update for folks at least, because it didn't when I tried for my clean install of HL. The name did change to show 1.4, and the date was today, but no exclamation point to indicate a "new" update.
