                Release Notes: Several very large features are included in this release. The aim is for this release to be as rock solid as possible, but at least one of the features added involved such changes that may warrant a bit of extra testing post-release before deploying it in production.

                  Release Notes: GROUP BY processing has been improved by using hash buckets. There is a new multikey hash join capability. Queries using the explicit JOIN syntax are now better optimized. There is faster and more powerful regular expression code, full support for IPv6 connections and IPv6 address data types, and major improvements in SSL performance and reliability. The free space map efficiently reuses empty index pages. There is an SQL-standard information schema, a new client-to-server protocol, a new version of full-text indexing, and a new autovacuum tool. libpq and ECPG applications are now fully thread-safe.

                    Release Notes: This release addresses a potentially serious (although rare) server startup failure that was recently reported. It is critical for users of PostgreSQL version 7.3.3, and highly recommended for all other PostgreSQL users.
