With more recent variations of Blender a number of modifying functions formerly available within the Tool Shelf, now the Toolbar, have already been reorganised or relocated so they really make more feeling contextually whilst working. One such device is Remove increases (RemDub), now called Merge by Distance, that collapses, or merges, coincidental vertices together.
Essential: according to the form of Blender 2.8 used, Merge by Distance may (nevertheless) be known as Remove Doubles.
Shown above (top image, in Blender 2.80), Merge by Distance continues to be known as Remove Doubles whilst still being available through the very same location, the Mesh menu whereas in Blender 2.9+ (bottom image) the event is Merge by Distance, once more into the exact same location.
Merge by Distance
The label Merge by Distance replaces eliminate Doubles even though the function stay unchanged.
