Hello everyone,

I am planning on tagging another release of osm2pgsql and would like to
ask if anyone is aware of any issues with the current osm2pgsql that
would prevent it from being a suitable candidate for a stable release.

The last release was done in mid April.

The main new feature of this release is probably the inclusion of the
lua tag processing. I.e. the ability to provide a user defined script
that allows to filter and transform tags, as well as determine if a way
or relation should be treated as a polygon or line. This allows to e.g.
normalize tagging schemas before the data enters the database and has
the potential to reduce the complexity of the mapnik style-sheets by not
having to do the normalization on the output side.

Another big addition in this release is the expansion of the regression
test suit, which now defines the behaviour of osm2pgsql fairly well,
particularly with respect to its multi-polygon behaviour.

Furthermore, osm2pgsql's database stylesheet was enhanced to include
many more tags that are considered "useless" and dropped and not
included in the db. These are mostly import related tags like tiger tags.

There are a number of bug fixes included. The most notable is probably a
long standing issue with the diff processing of relations.

Finally there are a number of documentation and code clean ups.

If people could test any of the new or any other functionality and
report back if there are any issues, this would help in ensuring a good
and stable release for osm2pgsql.

Thank you,
