• What: The “Azure Local host network requirements” link includes a versioned ?view=azloc-2601 query parameter.
  Why: This repo’s link guidance avoids version references in URLs so links don’t become stale across releases.
  How: Replace it with the non-versioned Learn URL (remove the view query parameter).
