Yes, it is. Pretty much every release of the game has a shorthand. Of course you have the Capital "E" editions shortened to 1E, 2E, etc. The variations of Basic have shorthand (BX, BECMI, etc). 3E's revision is simply 3.5. Up till now, probably the longest names for releases have been Black Box and Essentials. 5E(2014) is unnecessarily a mouthful that doesn't even do the intended job of avoiding the 3E/3.5E situation of making people consider the two releases as needing to be treated differently at the table.
