This release brings many bug fixes and performance improvements for the new Python frontend introduced in the last version. It can now be considered stable and has become the frontend recommended to be used for new installations. You find deployment guides in the documentation.
A new feature in this release is experimental support for exporting a Nominatim database to SQLite. The SQLite database can then be used with the new Python frontend or when using the Nominatim library. For more information about this, watch the talk at SotM-EU 2023 or read the blog posts.
A more complete list of changes can be found in the Changelog. Many thanks to the external contributors @robbe-haesendonck (for imports without superuser rights), @lujoh (for a command for cleaning deleted relations) and @pawel-wroniszewski (for fixing postcode validation).
Updating from any version 4.x.x to the new release is straightforward. Please follow the instructions from the migration guide. Updating from older versions is possible but not recommended. Please note that the migration to 4.3.0 requires building a new index needed by the frontend. It is therefore not recommended to migrate while a machine is in active use.
This is a bug fix release which resolves a low-level security issue in the CLI tool, where a SQL injection is possible with the nominatim admin --collect-os-info command. It also fixes the postcode output for addresses near boundaries in the PHP frontend and brings some smaller improvements to the Python frontend.

Updating from any version between 3.6.x and 4.3.x to the new release is straightforward. Please follow the instructions from the migration guide. Updating from older versions is possible but not recommended. Please note that the migration to 4.3.0 requires building a new index needed by the frontend. It is therefore not recommended to migrate while a machine is in active use.
This is a bug fix release, resolving the following issues:
nominatim admin --collect-os-info commandUsers of the 4.2 release series are advised to update to this latest release. Note: when updating from versions <= 4.2.2, make sure you read the migration instructions.
This is a minor bug fix release. It fixes a regression in the nominatim admin --warm command where the --reverse-only and --search-only parameters got switched.
This release also reintroduces result reranking according to how well results match the query to the experimental Python frontend.
This release brings a completely new frontend for Nominatim. It has been rewritten from scratch in Python. An improved search algorithm allows more flexibility in ranking search results. The code is also more modular, so that it will be easier to customize Nominatim. The frontend is also exposed as a Python library, so that it is no longer necessary to set up a web server when using a local installation. The Python frontend is currently still marked as experimental given that this is very new code. It is still very stable and already used in production on https://nominatim.openstreetmap.org. So try it out.
With this release, Nominatim will use the osm2pgsql flex output per default for the OSM data input. If you use one of the default styles, the transition will be automatic. If you are working with custom style, you need to change to the flex lua format soon. The former osm2pgsql gazetteer output is now deprecated and support will be removed completely in version 5.0.
This release fixes a compatibility issue with the new PostGIS 3.4 release. If you plan to use PostGIS 3.4 or later, you must update to this latest release or Nominatim's address lookup tables will be corrupted.
A minimum version of 3.7 for Python and 7.3 for PHP is now required.

Updating from any version between 3.6.x and 4.2.x to the new release is straightforward. Please follow the instructions from the migration guide. Updating from older versions is possible but not recommended. Please note that the migration to 4.3.0 requires building a new index needed by the frontend. It is therefore not recommended to migrate while a machine is in active use.
This is a bug fix release which fixes a fatal error which may be seen during updates when updating interpolations, see #3022. It also fixes handling of changefiles imported via nominatim add-data.

Updating from any version between 3.6.x and 4.2.x to the new release is straightforward. Please follow the instructions from the migration guide. Updating from older versions is possible but not recommended. Note: when updating from 4.2.x, you need to run nominatim refresh --functions after the upgrade.
This release fixes some bugs with the Nominatim CLI tool and the reverse API and adds small improvements to the database processing.
The release also extends support for the new Lua flex-style import scripts. There are now style implementations for all the standard styles of Nominatim available, which can be used as a base for customization. Please note that the changes are incompatible with the lua scripts from 4.2.1. If you have used older scripts, copy flex-base.lua into your project directory before upgrading.
