/store/pub/.htaccess Options +FollowSymLinks VERSUS Options +SymLinksIfOwnerMatch

[Zean]

I am upgrading from v1.5.0 to v1.5.4 so I have been documenting changes in my live v1.5.0 store that I need to carry forward to the v1.5.4 store.
I notice the .htaccess file in my live v1.5.0 /store/pub/ directory had been modified:

ORIGINAL v1.5.0 CODE:
## the following line is needed to allow Download-By-Redirect to work
Options +FollowSymLinks

LIVE STORE v1.5.0 CODE:
## the following line is needed to allow Download-By-Redirect to work
# For security reasons, Option followsymlinks cannot be overridden.
# Options +FollowSymLinks
Options +SymLinksIfOwnerMatch

I don't recall why or even if I made this change nor what effect it has.
Any help explaining what this does and if you think I should be carrying it forward to my v1.5.4 would be greatly appreciated.

Live Store:
Zen Cart v1.5.0
No plugins
Zen Cart installed via FTP and run zc_install
PHP Version: 5.2.17 (Zend: 2.2.0)
MySQL 5.5.42-37.1-log

If your web host doesn't allow the FollowSymlinks option, comment it out and use `Options +SymLinksOfOwnerMatch`

So it might be that your host does not allow the FollowSymlinks option...and why you made the alteration
Just guessing of course
