Magento 2.4.3 – What we Think and What you Should Do

Magento 2.0 was released in November 2015. In case you can’t remember that far back, Adele’s “25 album” shattered all sales records by selling 3.38 million copies during the first week of its release in the United States. World leaders gathered for the United Nations Climate Change talks at a convention center just north of Paris, France, and a Russian warplane was shot down over Turkey. Well, Magento has not been idle in the intervening years, but in August, the company has made the BIG STEP to launch Magento 2.4.3.
