It was made less ‘offensive’. That has happened to a lot of hymns, although I can’t think of any other titles right now. It even happens to praise choruses. A couple of weeks ago, we sang The Servant Song, and “Brother, let me be your servant”, was changed to, “Will you let me be your servant?”
Inclusivity and non-offensiveness.

I only recently learned that the original lyrics to “The Yellow Rose of Texas” refer to the singer as a black man (this doesn’t bother me much, but it does amuse me). The lyrics were changed in the 1950’s.
This doesn’t really annoy me so much as it amuses me. Songs change over time, as do stories, for various reasons (cultural, economical, whatever). Really, the only time that a lyric in a song was changed that really annoyed me was when I heard the Aggie Singing Cadets sing this line while singing the Spirit of Aggieland:
“We are the Aggies, the Aggies are true! We are from Texas A M U!”
The CORRECT line raises chin in a haughty matter-of-fact way is:
“We are the Aggies, the Agges are we! We are from Texas A M C!”
The guy leading the Singing Cadets changed the lyrics at the end to reflect that Texas A&M College had just become a University. That said, everyone EXCEPT for the Singing Cadets sings the song the CORRECT, TRADITIONAL way. 
On an unrelated note, you can sing most of the poems written by Emily Dickenson to the tune of “Yellow Rose of Texas” because most of her poems, like the song, are written in Ballad Meter.
