This bug-fix release fixes two important issues with osm2pgsql:
- osm2pgsql might get stuck during updates when running with Postgresql 12
- osm2pgsql might hang when processing extremely complex multipolygons
All users should update to this latest version when they run regular updates on their database or plan to import new data that includes North America. Nominatim 3.5.0 installations can be updated directly without changes to the database. For upgrading from older versions please consult the migration guide.
