Osm2pgsql 0.87.3 has been released. This development release primarily fixes bugs, but some of the bug fixes make other features usable.

Included is a bug fix for the lockfree queue implementation. Anyone using versions 0.87.0 to 0.87.3-dev, parallel processing, Boost 1.53 or newer, and not using –without-lockfree should immediately upgrade or stop using parallel processing. No data corruption issues have been observed, but the lockfree implementation may have been buggy on all systems.

There have been various fixes with moving hand-written C structures to C++ standard library equivalents and other code cleanups. The main user-facing changes are

• The multi-backend should now be functional, with an example which creates separate tables for bus nodes, highways, and buildings

• –without-lockfree is no longer needed on OS X, BSD and some Linux distributions and architectures. This should simplify downstream build scripts for multi-architecture builds and improve speed on any OS that required the option before.

• nodecachereader should now work with node IDs > 2^31. This is a separate utility program, and obviously isn’t used much

• Nominatim-related performance improvements

• Many autoconf macros have been updated. This should ease configuration on non-standard systems.

This may be the last tagged release that does not require C++11. We have no current PRs which will require C++11, but would be willing to accept them.

As always, bugs can be raised at https://github.com/openstreetmap/osm2pgsql/issues. I’m particularly interested if package maintainers have concerns. If osm2pgsql isn’t packaged for your OS and you want to do so and have questions about the osm2pgsql side, please ask them too.

Many thanks to those who have contributed code to this and previous releases.
