prepare 4.2.3 release

Snapping a line to a point before splitting was meant to ensure
that the split point is really on the line. However, ST_Snap() does
not always behave well for this case. It may shorten the interpolation
line in some cases with the result that two points housenumbers
suddenly fall on the same point. It might also shorten the line down
to a single point which then makes ST_Split() crash.

Switch to a combination of ST_LineLocatePoint and ST_LineSubString
instead, which guarantees to keep the original geometry. Explicitly
handle the corner cases, where the split point falls on the beginning
or end of the line.

+## Releases
+
+Nominatim follows semantic versioning. Major releases are done for large changes
+that require (or at least strongly recommend) a reimport of the databases.
+Minor releases can usually be applied to exisiting databases Patch releases
+contain bug fixes only and are released from a separate branch where the
+relevant changes are cherry-picked from the master branch.
+
+Checklist for releases:
+
+* [ ] increase version in `nominatim/version.py` and CMakeLists.txt
+* [ ] update `ChangeLog` (copy information from patch releases from release branch)
+* [ ] complete `docs/admin/Migration.md`
+* [ ] update EOL dates in `SECURITY.md`
+* [ ] commit and make sure CI tests pass
+* [ ] test migration
+  * download, build and import previous version
+  * migrate using master version
+  * run updates using master version
+* [ ] prepare tarball:
+  * `git clone --recursive https://github.com/osm-search/Nominatim` (switch to right branch!)
+  * `rm -r .git* osm2pgsql/.git*`
+  * copy country data into `data/`
+  * add version to base directory and package
+* [ ] upload tarball to https://nominatim.org
+* [ ] prepare documentation
+  * check out new docs branch
+  * change git checkout instructions to tarball download instructions or adapt version on existing ones
+  * build documentation and copy to https://github.com/osm-search/nominatim-org-site
+  * add new version to history
+* [ ] check release tarball
+  * download tarball as per new documentation instructions
+  * compile and import Nominatim
+  * run `nominatim --version` to confirm correct version
+* [ ] tag new release and add a release on github.com

+#### 7. My result has a wrong postcode. Where does it come from?
+
+Most places in OSM don't have a postcode, so Nominatim tries to interpolate
+one. It first look at all the places that make up the address of the place.
+If one of them has a postcode defined, this is the one to be used. When
+none of the address parts has a postcode either, Nominatim interpolates one
+from the surrounding objects. If the postcode is for your result is one, then
+most of the time there is an OSM object with the wrong postcode nearby.
+
+To find the bad postcode, go to
+[https://nominatim.openstreetmap.org](https://nominatim.openstreetmap.org)
+and search for your place. When you have found it, click on the 'details' link
+under the result to go to the details page. There is a field 'Computed Postcode'
+which should display the bad postcode. Click on the 'how?' link. A small
+explanation text appears. It contains a link to a query for Overpass Turbo.
+Click on that and you get a map with all places in the area that have the bad
+postcode. If none is displayed, zoom the map out a bit and then click on 'Run'.
+
+Now go to [OpenStreetMap](https://openstreetmap.org) and fix the error you
+have just found. It will take at least a day for Nominatim to catch up with
+your data fix. Sometimes longer, depending on how much editing activity is in
+the area.

+## Importance
+
+Search requests can yield multiple results which match equally well with
+the original query. In such case Nominatim needs to order the results
+according to a different criterion: importance. This is a measure for how
+likely it is that a user will search for a given place. This section explains
+the sources Nominatim uses for computing importance of a place and how to
+customize them.
+
+### How importance is computed
+
+The main value for importance is derived from page ranking values for Wikipedia
+pages for a place. For places that do not have their own
+Wikipedia page, a formula is used that derives a static importance from the
+places [search rank](../customize/Ranking.md#search-rank).
+
+In a second step, a secondary importance value is added which is meant to
+represent how well-known the general area is where the place is located. It
+functions as a tie-breaker between places with very similar primary
+importance values.
+
+nominatim.org has preprocessed importance tables for the
+[primary Wikipedia rankings](https://nominatim.org/data/wikimedia-importance.sql.gz)
+and for a secondary importance based on the number of tile views on openstreetmap.org.
+
+### Customizing secondary importance
+
+The secondary importance is implemented as a simple
+[Postgis raster](https://postgis.net/docs/raster.html) table, where Nominatim
+looks up the value for the coordinates of the centroid of a place. You can
+provide your own secondary importance raster in form of an SQL file named
+`secondary_importance.sql.gz` in your project directory.
+
+The SQL file needs to drop and (re)create a table `secondary_importance` which
+must as a minimum contain a column `rast` of type `raster`. The raster must
+be in EPSG:4326 and contain 16bit unsigned ints
+(`raster_constraint_pixel_types(rast) = '{16BUI}'). Any other columns in the
+table will be ignored. You must furthermore create an index as follows:
+
+```
+CREATE INDEX ON secondary_importance USING gist(ST_ConvexHull(gist))
+```
+
+The following raster2pgsql command will create a table that conforms to
+the requirements:
+
+```
+raster2pgsql -I -C -Y -d -t 128x128 input.tiff public.secondary_importance
+```
