Was the prisoner’s name “Jesus Barabbas,” or just “Barabbas”? Why are the translations different, and why did the NIV change his name from the 1984 to the 2011 editions?

One of the ongoing attacks on modern translations has to do with the Trinitarian formula in 1 John 5:7–8. The accusation is that modern translators are dropping out the divinity of Christ from the Bible. I’ve now actually seen the factual evidence of why this is not true.
