Luka was released on January 30 2009. She is the first vocaloid made by a Japanese company to have an English voicebank. Her English has many problems and is hard to use, but it is still high quality and an achievement. Luka's success was incredible, and she remains the favorite of many. Her original boxart was designed by KEI with wind instruments and class in mind. Luka's voice is smooth and lovely, and the most emotional of all the vocaloids. Though it is not without problems, of the V1 and V2 Crypton vocaloids she has the easiest voicebank to use, and one of the prettiest to boot.
Luka's updates and appends, officially named Megurine Luka V4X, are nearing release and March 19 2015 has been given as the release date. One of Luka's new English voice banks was demo'ed at the 2014 NYCC, singing the English version of Just Be Friends. She also sang this song in full at the 2014 Miku Expo concerts in LA and NY. She is Crypton's first V4. She is the first Vocaloid to have appends that are designed to work together using a new feature of Piapro Studio called E.V.E.C. (short for Enhanced Voice Expression Control). Here is her first sample using E.V.E.C.:

Here is her sample using VOCALOID4. This shows off her amazing range of expression:
May the warmth of her voice find you even in the coldest of places.
May her gentle sound comfort and shield you against the insults of life.
