WCS Patch18 upgrade Compatibility with GSF 11.6.1

[RajendarPilli]

Hello GST Experts,
We are using WCS+GST integration Site.
WCS 11.1.1.6.1 Version
GSF 11.6.1
To apply Patch 18 to WCS(GST integrated), do we need to change anything from GSF?
does the current GSF version(11.6.1) compatible with Patch18(11.1.1.6.1)?
Thank you,
Rajendar Pilli
