Variant in 2:198

Can someone shed some light on the variant below : >Ukaz, Majanna and Dhul-Majaz were marketplaces in the Pre-Islamic period of ignorance. When Islam came, Muslims felt that marketing there might be a sin. So, the Divine Inspiration came: "There is no harm for you to seek the bounty of your Lord (in the seasons of Hajj)." (2.198) **Ibn `Abbas recited the Verse in this way**. (Sahih al-Bukhari 2050 Book 34, Hadith 4) Can this mode of recitation be considered abrogated?
