Following the PS4 HEN 2.1.3 updates, PlayStation 4 homebrew developer @TheDarkprograme shared a PS4HEN 2.1.4 Github fork (from SiSTR0's repository, also forked from xvortex) via Twitter that includes save data mount patches from ChendoChap who released both PS4 Cheater and PlayStation 4 Save Mounter previously with feedback from @Leeful in fixing reported issues for certain games.

To quote from Leeful on this latest PS4 HEN 2.1.4 revision:
"All I know is that the save mount patch that has been added to Hen 2.1.4 can be used with some homebrew that is being developed.
Apart from this patch there is no difference between this and the previous version on Hen."
And from the README.md: PS4HEN v2.1.4
