Upgrading existing versions¶

Disk Quota HSQL DB usage (GeoServer 2.23 and newer)¶

As of GeoServer 2.23, H2 DB support will be replaced with HSQL DB for Tile Caching / Disk Quota store.

• H2 option under “Disk quota store type” and “Target database type” is replaced with HSQL.

• The default store type will be in-process HSQL.

• Existing installations with in-process H2 selection will automatically be migrated to in-process HSQL. Old H2 database files will remain in gwc/diskquota_page_store_h2/ under the data directory. You may delete those or leave them for a possible downgrade.

• Important: Existing installations with external H2 database selection will not be migrated automatically. You will get an error message at startup and disk quota will be disabled, unless you use a plugin/extension with H2 dependency. But other features of GeoServer will keep working. You can go to Disk Quota page and configure an external HSQL database or switch to in-process HSQL. In case you want to keep using H2 as an in-process/external database, you can add H2 store plugin or any other extension or plugin that has H2 dependency.

• GeoServer installations with extensions/plugins having H2 dependency will still have H2 option under “Disk quota store type” and “Target database type”.

Remote requests control (GeoServer 2.22 and newer)¶

As of GeoServer 2.22, remote requests control has been added, but disabled by default, in GeoServer. You should consider enabling it and providing safe urls that will be allowed.

When enabled, this feature allows administrators to control which remote requests are allowed to be made to GeoServer. When you first enable it, no authorizations are included, thus GeoServer will deny remote requests originating from user interaction. In particular, the following use cases are affected:

• WMS operations with remotely fetch styles (sld parameter) and style referencing remote icons (in general, icons outside of the data directory). As a reminder, when a remote icon is not found, GeoServer will fall back to a default icon, a gray square with a black border.

• WMS “feature portrayal” with dynamic remote WFS references provided in the request (REMOTE_OWS_TYPE and REMOTE_OWS_URL parameters).

• WPS remote inputs via either GET or POST request (e.g., remote GeoJSON file source).

The list of locations that are safe to contact can be configured using the URL Checks page.

Log4J Upgrade (GeoServer 2.21 and newer)¶

As of GeoServer 2.21, the logging system used by GeoServer has been upgraded from Log4J 1.2 to Log4J 2.

• GeoServer now uses xml files for the built-in logging profiles (previously properties files were used).

• The built-in logging profiles are upgraded with xml files:

  DEFAULT_LOGGING.xml

  DEFAULT_LOGGING.properties.bak

• A backup of the prior properties files are created during the upgrade process. If you had previously made any customizations to a built-in profiles these backup files may be used as a reference when customizing the xml file.

• Log4J 2 does have the ability to read Log4j 1.2 properties files although not all features are supported.

  Any custom properties files you created will continue to be available for use.

• If necessary you can recover a customization you performed to a built-in logging profile by restoring to a different filename. To recover a customization from PRODUCTION_LOGGING.properties.bak rename the file to PRODUCTION_LOGGING.properties.bak to CUSTOM_LOGGING.properties.

• If you never plan to customize the built-in logging profiles the UPDATE_BUILT_IN_LOGGING_PROFILES=true system property will always ensure you have our latest recommendation.

JTS Type Bindings (GeoServer 2.14 and newer)¶

As of GeoServer 2.14, the output produced by REST featuretype and structured coverage requests using a different package name (org.locationtech instead of com.vividsolutions) for geometry type bindings, due to the upgrade to JTS (Java Topology Suite) 1.16.0. For example:

Before:

...
<attribute>
  <name>geom</name>
  <minOccurs>0</minOccurs>
  <maxOccurs>1</maxOccurs>
  <nillable>true</nillable>
  <binding>com.vividsolutions.jts.geom.Point</binding>
</attribute>
...

After:

...
<attribute>
  <name>geom</name>
  <minOccurs>0</minOccurs>
  <maxOccurs>1</maxOccurs>
  <nillable>true</nillable>
  <binding>org.locationtech.jts.geom.Point</binding>
</attribute>
...

Any REST clients which rely on this binding information should be updated to support the new names.

GeoJSON encoding (GeoServer 2.6 and newer)¶

As of GeoServer 2.6, the GeoJSON produced by the WFS service no longer uses a non-standard encoding for the CRS. To re-enable this behavior for compatibility purposes, set GEOSERVER_GEOJSON_LEGACY_CRS=true as a system property, context parameter, or environment variable.
