[Geocoding] Nominatim 2.3.1 released

[Sarah Hoffmann]

Hi,

we have just released a new stable version 2.3.1 of Nominatim.

This is a minor release that fixes a fatal parsing problem during
setup. If you already have a Nominatim installation, you can safely
ignore this release.

Technical details: the layout of the directory view on planet.osm.org
has changed, so that the download of the state files no longer worked
and the setup process exited prematurely with an error. This has been
fixed and now the old and new directory layout can be parsed.

Installation instructions for this release can be found at the usual
place: https://wiki.osm.org/wiki/Nominatim/Installation

Kind regards

Sarah
