<title>PostGIS 3.2.0 (Olivier Courtin Edition)</title>
<para>2021/12/18</para>
<para>This version requires PostgreSQL 9.6 or higher, GEOS 3.6 or higher, and Proj 4.9+
Additional features are enabled if you are running GEOS 3.9+
(and ST_MakeValid enhancements with 3.10+),

<para>Due to some query performance degradation
with the new PG14 fast index build ,
we have decided to disable the feature by default
until we get more user testing
as to the true impact of real-world queries.
If you are running PG14+, you can reenable it by doing:</para>
<programlisting>ALTER OPERATOR FAMILY gist_geometry_ops_2d USING gist
ADD FUNCTION 11 (geometry)
geometry_gist_sortsupport_2d (internal);
</programlisting>
<para>To revert the change:</para>

<para>-- If you have been using deprecated functions CHANGE your apps or suffer the consequences.
If you don't see a function documented -- it ain't supported or it is an internal function.
Some constraints in older tables were built with deprecated functions.

that rely on deprecated functions, please refer to <xref linkend="legacy_faq" /> for more details.</para>

<title>Credits</title>
<para>This release includes code from Mark Cave Ayland for caching of
proj4 objects. Markus Schaber added many improvements in his JDBC2
code. Alex Bodnaru helped with PostgreSQL source dependency relief and
provided Debian specfiles. Michael Fuhr tested new things on Solaris
arch. David Techer and Gerald Fenoy helped testing GEOS C-API
connector. Hartmut Tschauner provided code for the azimuth() function.
Devrim GUNDUZ provided RPM specfiles. Carl Anderson helped with the
new area building functions. See the <link
