Usually people do not update these examples.
But generally when people update something there sharing they indicate a update with -
v1.1 - Made ?? Even more stable, added user support or whatever.
changelog 1.1 -Made ?? Even more stable, added user support or whatever.
You will see this often in the third party plugins section as there something that users regulary update.
But as for this thread, New things are added to the bottom of the list of each category.
