There are <emphasis>many</emphasis> new features and improvements in this release.
Thanks to our developers and maintainers, nearly every aspect of the system
has received some attention since the previous release.
Here is a brief, incomplete summary:
<itemizedlist spacing="compact">
<listitem>
<para>
Views and rules are now functional thanks to extensive new code in the
rewrite rules system from Jan Wieck. He also wrote a chapter on it
for the <citetitle>Programmer's Guide</citetitle>.
</para>
</listitem>
<listitem>
<para>
Jan also contributed a second procedural language, PL/pgSQL, to go with the
original PL/pgTCL procedural language he contributed last release.
</para>
</listitem>
<listitem>
<para>
We have optional multiple-byte character set support from Tatsuo Iishi
to complement our existing locale support.
</para>
</listitem>
<listitem>
<para>
Client/server communications has been cleaned up, with better support for
asynchronous messages and interrupts thanks to Tom Lane.
</para>
</listitem>
<listitem>
<para>
The parser will now perform automatic type coersion to match arguments
to available operators and functions, and to match columns and expressions
with target columns. This uses a generic mechanism which supports
the type extensibility features of <productname>Postgres</productname>.
There is a new chapter in the <citetitle>User's Guide</citetitle>
which covers this topic.
</para>
</listitem>
<listitem>
<para>
Three new data types have been added.
Two types, <type>inet</type> and <type>cidr</type>, support various forms
of IP network, subnet, and machine addressing. There is now an 8-byte integer
type available on some platforms. See the chapter on data types
in the <citetitle>User's Guide</citetitle> for details.
A fourth type, <type>serial</type>, is now supported by the parser as an
amalgam of the <type>int4</type> type, a sequence, and a unique index.
</para>
</listitem>
<listitem>
<para>
Several more <acronym>SQL92</acronym>-compatible syntax features have been
added, including <command>INSERT DEFAULT VALUES</command>
</para>

The automatic configuration and installation system has received some
attention, and should be more robust for more platforms than it has ever
been.
