Changes (by jewillco):

  * status:  new => closed
  * resolution:  => fixed

Comment:

 (In [80639]) Fixed relax logic to not write predecessor map unless
 distance was actually changed in memory (although this case will never be
 hit unless registers have extra precision compared to memory); fixes #7226
