You didn't say what version you upgraded from, but it must have been at least
3.13.0.

Always read the release notes, they're written for reasons such as this.

The release notes for version 3.13.1 include this item:

* A hidden pref has been added, 'next_on_delete'. This controls the
  message selection when a message is deleted. A setting of '0'
  which cause the previous, older message to be selected, a setting
  of '1' will cause the next, newer message to be selected.
