v2.15.0

Added

• This month / Last month / Everything buttons in the export dialog,
  so the from-date does not have to be typed correctly to get the range you
  meant.

Changed

• The export dialog opens on the start of last month rather than this one.
  The old default silently excluded the month people most often open the dialog
  about: a month closes, its rows never arrived, and an export started on the
  first of the new month sends only the new month — reporting success while
  changing nothing.
