MTP Mode is enabled

Last night I just updated my HTC One to version 4.3 Jelly Bean. When I connected it to my computer I saw “MTP Mode is enabled”. So it seems this is already there since the version 3.0 Honeycomb but I didn’t notice it back than. At least it was not so obvious.
And what does it stand for? MTP simply stands for Media Transfer Protocol.
