[Geocoding] Nominatim 3.0.0 released

[Sarah Hoffmann]

Hi,

we are happy to announce that release of Nominatim 3.0.0.

This release brings a major overhaul of the source code and database
internals. The result is a much smaller database and improved query
response times. The major changes include:

 * move to CMake for the build framework
 * introduce on-the-fly computation of address interpolations
 * osm2pgsql uses the more efficient libosmium data structures
 * cleanup of the PHP code structure
 * complete overhaul of test infrastructure

The major new feature concerns the reverse endpoint: it is now able
to return geometries using the polygon_* parameters already known
from the search endpoint.

For a more complete list of changes, see the ChangeLog file.

The release can be downloaded at:

Starting with this release, installation instructions for releases
have moved to:

  http://nominatim.org/release-docs/latest/Installation

Please read them carefully when upgrading as the build process has
changed significantly.

This release is not database-compatible with older versions.
A complete database reimport is required when upgrading.

Kind regards

Sarah
