HI there, and welcome to OSM :)

I was going through recent changesets in the Calgary area, and came across this one.
It appears you've upgraded an alley from an alley to a residential road, when in reality this shouldn't have been changed, as alleys do not meet the definition of a residential road. I've reverted that change for you.

As well, you added a highway=pedestrian leading up to the rear of a house. highway=pedestrian has a very specific use case, whose use you can read about on its wiki page: https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpedestrian. The only road meeting this definition in Calgary is Stephen Avenue, outside of some very limited specific uses. I've gone ahead and downgraded this to a highway=footway with access=private (as it leads to a private residence).
