This release does not introduce any new functionality. A huge amount of internal and architecture tasks were done instead. New compiler version used as well as new exception tracer implemented. Some little changes, not worthy of mention, are also present, e.g. standard Color Dialog etc.
In this release we focused on changes in future 9.2 version of the PostgreSQL server. Support for new JSON and range types introduced. Internal SQL parser improved a lot and is fully compatible with Postgres 9.1 SQL dialect. Collation support for tables introduced as well.
