No idea how you came to lose that option..?
I'm not sure how to add files here but this is the code for the script called .. drop-shadow.scm which will appear in the Filters> Light and Shadows section. Save it as a .scm file and put it in the scripts folder. Should be a straightforward process.

;
; CHANGE-LOG:
; 1.00 - initial release
; 1.01 - fixed the problem with a remaining copy of the selection
; 1.02 - some code cleanup, no real changes
; 1.03 - can't call gimp-edit-fill until layer is added to image!
; 1.04
; 1.05 - replaced deprecated function calls with new ones for 2.8
;

;
;
; Adds a drop-shadow of the current selection or alpha-channel.
;
; This script is derived from my script add-shadow, which has become
; obsolete now. Thanks to Andrew Donkin (ard@cs.waikato.ac.nz) for his
; idea to add alpha-support to add-shadow.
