The "updated" ( 2.7) files are here:
https://sourceforge.net/projects/gimp-packagers/files/ This is a 7zip package, which Windows users usually do not have an unpacker, so I repackaged as a plain zip file here:

For Gimp 2.10 installation, because of the way folders are now recognised as plug-ins (not going to work with GAP) my advice is add the Gap folders explicitly to the plug-ins/scripts paths in
Edit -> Preferences -> Folders
It might go like this:
Unzip the zip (In Windows, click on the zip to open it) That gives a folder GAP27. Put that folder in User\your-name\
Now you have to add to the Gimp Folders paths.
Edit -> Preferences -> Folders
For the plugins: Select the Plug-ins entry
1. Click on the add a new folder icon
2. Click on the Open a file selector... icon
3. Browse for the User\your-name\Gap27\plug-ins folder
4. Ok that which should get you....
5. A new entry in the paths list
6. Some time you will have to OK that either now or after adding the scripts path.
For the scripts: Select the Scripts entry
Exactly the same procedure as the plugins.
OK that, restart Gimp for the extra paths to take effect.
That gives a new menu entry Video. How much of GAP now works is debatable. Expect some functions not to work.
