versions of our database system, including 9.5.4, 9.4.9, 9.3.14, 9.2.18 and
9.1.23. This release fixes two security issues. It also patches a number of
other bugs reported over the last three months. Users who rely on security
isolation between database users should update as soon as possible. Other users
should plan to update at the next convenient downtime.

Security Fixes for Regular Expressions, PL/Java
This release closes security hole CVE-2016-0773, an issue with regular
expression (regex) parsing. Prior code allowed users to pass in expressions
which included out-of-range Unicode characters, triggering a backend crash.
This issue is critical for PostgreSQL systems with untrusted users or which
generate regexes based on user input.
The update also fixes CVE-2016-0766, a privilege escalation issue for users of
PL/Java. Certain custom configuration settings (GUCS) for PL/Java will now be
modifiable only by the database superuser

release of PostgreSQL 9.4, the latest version of the world's leading
open source database, is available today. This beta contains previews
of all of the features which will be available in version 9.4, and is
ready for testing by the worldwide PostgreSQL community. Please
download, test, and report what you find.
Major Features
--------------
The new major features available for testing in this beta include:
* JSONB: 9.4 includes the new JSONB "binary JSON" type. This new
storage format for document data is higher-performance, and comes with
indexing, functions and operators for manipulating JSON data.
* Replication: The new Data Change Streaming API allows decoding and
transformation of the replication stream. This lays the foundation
for new replication tools that support high-speed and more flexible
replication and scale-out solutions.
* Materialized Views with "Refresh Concurrently", which permit
fast-response background summary reports for complex data.
* ALTER SYSTEM SET, which enables modifications to postgresql.conf
from the SQL command line and from remote clients, easing
administration tasks.
