How many 'versions' of the holy Quran is there today؟
At least two, probably more (I am pretty sure about the third
one, but can't prove it yet, so I am not going to say where and
what just yet), but it is common knowledge that the Hafs text
and the Warsh text (mainly used in Northwest Africa) are
different not only in the vowels but also in some consonants.
The differences are small, but they are there. And both of them
are for sale and in use today. Hafs is the much more common one.
The third version I have heard about has by far more substantial
differences in comparison to the other two. For the Warsh and
Hafs differences see a few examples at:

Some of the quotes from the Surah 2 are given here:
This is the Book; in it is guidance sure, without doubt, to those who fear Allah.
And your Allah is One Allah. There is no god but He, Most Gracious, Most Merciful.
It is He Who hath created for you all things that are on earth; Moreover His design comprehended the heavens, for He gave order and perfection to the seven firmaments; and of all things He hath perfect knowledge.
To Allah belong the east and the West: Whithersoever ye turn, there is the presence of Allah. For Allah is all-Pervading, all-Knowing.
Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth).
O ye people! Adore your Guardian-Lord, who created you and those who came before you, that ye may have the chance to learn righteousness.
Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth).
Be steadfast in prayer and regular in charity: And whatever good ye send forth for your souls before you, ye shall find it with Allah. for Allah sees Well all that ye do.
Be sure we shall test you with something of fear and hunger, some loss in goods or lives or the fruits (of your toil), but give glad tidings to those who patiently persevere.
"Our Lord! make of us Muslims, bowing to Thy (Will), and of our progeny a people Muslim, bowing to Thy (will); and show us our place for the celebration of (due) rites; and turn unto us (in Mercy); for Thou art the Oft-Returning, Most Merciful.
Fight in the cause of Allah those who fight you, but do not transgress limits; for Allah loveth not transgressors.
O ye people! Eat of what is on earth, Lawful and good; and do not follow the footsteps of the evil one, for he is to you an avowed enemy.
Cover not Truth with falsehood, nor conceal the Truth when ye know (what it is). /
