Apart from the misspelling correction, I don't see how the change is an improvement.

    Edgar Allan Poe invented the murder mystery genre we know today 
    with Inspector Dupin, a purveyor of “ratiocination,” or intensive reasoning
    — who was introduced to the world in The Murders on the Rue Morgue.

Previously the link [Inspector Dupin] was about Edgar Allan Poe's character "Not-An-Inspector Dupin" who was introduced to the world in The Murders on the Rue Morgue.

Now the link is about the TV movie "Inspector Dupin" which is based on German novels published in the last decade and unrelated to The Murders on the Rue Morgue, Edgar Allan Poe or the invention of the murder mystery genre we know today.
