Comment 2 for bug 2066385

you may probably didn't read the changelog (well or not)

this is, clearly announced a new preference:
#2044601 preference to always prompt for a target txn when adding xfer

preferences, means you can uncheck it
for new users it was decided to set this new preference to true by default

yes doc might be not completely up to date on some points, I don't always think to change everything
