Feedback is welcome, in particular from downstream packagers.

You can get the release from git or 
https://github.com/openstreetmap/osm2pgsql/releases/tag/0.92.0-RC1.

The big changes are

- PostgreSQL 9.1 + PostGIS 2.0 or later are now required, which has lead 
to performance improvements and cleanups

specifying 900913.
- All invalid and empty geometries should now be excluded

Other changes are
- A new option to change the max bbox at which polygons will expire all 
the tiles in them, not just the boundary. Only used when generating 
expired tile lists. See https://github.com/openstreetmap/osm2pgsql/pull/570
- Behavior fixes for C transforms and tables with no columns
- More numeric datatypes are allowed for table columns in C tagtransforms
- Lua is now required by default
- Code fixes, particularly replacement of C memory management
