The GeoServer team is pleased to announce the release of GeoServer 2.8.4. Download bundles are provided (bin, war, dmg and exe) along with documentation and extensions.

GeoServer 2.8.4 is the latest stable release of GeoServer and is recommended for production deployment. This release is made in conjunction with GeoTools 14.4. Thanks to all contributors. Fixes and new functionality include:

• Security fix for a reflected XSS vulnerability

• Fix for potential out of memory state when rendering lots of very small tiles

• Fix for an embedded GeoFence issue that caused user settings to be lost after a restart

• Improved ImageMosaic creation and update speed for databases with many tables

• Monitoring extension fixes for RemoteUser logging and monitoring hibernate extension causing startup issues to GeoServer

• CSS styling extension related fix: A bug in CSS to SLD conversion led in some cases to performance issues with the generated SLD

• PDF printing related fixes to properly render SLD “shape://horline” symbol, prevent invalid polygon generation and avoid potential out of memory state or very large files when handling large outputs with dense hatch fills

• And much more, see all the 24 tickets resolved in the release notes

Thanks to Alessandro Parma (GeoSolutions) and Andrea Aime (GeoSolutions) for this release.

The GeoServer team is overjoyed to announce the GeoServer 2.9.0 release. Downloads are available (zip, war, dmg and exe) along with docs and extensions. We will be working with OSGeo to provide a signed DMG download shortly.

This release is made by Jody Garnett (Boundless) and Devon Tucker (Boundless) with help from Andrea Aime and Alessandro Parma (GeoSolutions) in conjunction with the GeoWebCache 1.9.0 and GeoTools 15.0 releases.

Highlights

As this is a major release GeoServer 2.9.0 includes a number of important changes, including both new features and compatibility requirements.

Java 8 Required

This release requires the use of Java 8, and is compatible with both Oracle JDK and Open JDK.

Servlet 3 Required

Due to internal upgrades GeoServer now requires a Servlet 3 compatible application server.

• The standalone downloads for Mac, Windows and Linux has been update to Jetty 9.2.13

• Tomcat users will be required to upgrade to Tomcat 7 or newer (for those doing a WAR install)

Web Administration

A number of improvements and clarifications have been made to the web administration application:

• The Layers and Layer Preview has been restructured to lead with layer title in the first column, layer workspace and name combined into the second column. By popular request these pages now use layer (rather than resource) actions with “Add a new layer”, and “Remove selected layers”.

• You can now generate layer bounds from either the data bounds or from the spatial reference system bounds. This is handy for dynamic layers that will have content added to them over time.

• Styles can now include an optional legend graphic for use in WMS GetCapabilities.

• Global Settings have been grouped into a section for configuration of web services and a section for internal settings (affecting the GeoServer application as a whole).

• Image Processing and Raster Access are clearly presented with controls for memory and CPU use. Previously these screens were expressed in terms of the internal components used.

User Guide

The user guide has been restructured:

• The document layout has been reduced to a smaller number of sections

  • Data management covers vector, raster, database and web services along with common settings

  • Services (WMS, WFS, WCS, WPS, CSW) have been gathered into a single section for consistency, even though WPS is an optional install.

• The duplication between service description and application configuration has been resolved:

  • Each Service is described, both in terms of functionality, alongside details on how the service is configured

  • The Web administration interface section remains focused on on application configuration, linking to to service configuration above (to prevent duplication).

• Tutorials have been gathered into a single location.

Resource REST API

A new feature for GeoServer 2.9 is the ability to manage resources (icons, fonts, configuration files) via the REST API.  This approach works with both the default file based GeoServer configuration and JDBCConfig community module.

• **GET: rest/resource/styles/grass_fill.png? **

• GET: rest/resource/styles/grass_fill.png?operation=metadata&format=json

  {  ”ResourceMetadata”: { “name”: “grass_fill.png”, “parent”: { “path”: “/styles”, “link”: { “href”: “http://localhost:8080/geoserver/rest/resource/styles”, “rel”: “alternate”, “type”: “application/json” } }, “lastModified”: “2016-05-27 19:31:30.0 UTC”, “type”: “resource” } }

About/Status REST API

The about REST API already reports on the jars installed and the version of high-level components. GeoServer 2.9 includes the addition of about/status which reports not only what components are installed, but if they are correctly functioning. We will be working with this endpoint in subsequent releases to better reporting on GeoServer installation status.

• GET rest/about/status

Offset line support

Symbology Encoding 1.0 offset line is now supported, along with a vendor extension to use the same in SLD 1.0, and CSS support via the “stroke-offset” property. Here are a couple of screenshots of the effects that can be achieved by using offset line.

UTFGrid support in WMS and WMTS

GeoServer WMS and WMTS now support UTFGrid as an output format, to get fast and rich feature info on the client side. The WMS output has been tested with OpenLayers 2 by applying this patch, while not officially tested it should also work with OpenLayers 3 and Leaflet using the appropriate URL templates against the WMTS output.

Improved WPS aggregation process with group by

The Aggregate process has been improved to support group-by against any data source, with the ability to turn the execution in an efficient SQL with group by query, if the underlying data source is a database. In case of group-by a rich JSON output is generated, than can then be used to drive client side libraries such as D3 to generate nice charts for your users:

{
  "GroupByAttributes": [ "groupingAttribute" ],
  "AggregationResults": [
    [ "Class1", 18 ],
    [ "Class2", 1 ],
    [ "Class3", 3 ],
    [ "Class4", 3 ]
  ],
  "AggregationFunctions": [ "Count" ],
  "AggregationAttribute": "countingAttribute"
}

Vector masking support for GDAL based formats

All GDAL based formats now support vector masks to cut NODATA areas away from rendering, similar to what image mosaic already supported. Here is a sample, cutting away some areas from a JPEG 2000 image (the format adds compression artifacts at the border, thus the input transparent color cannot be used to achieve a similar effect).

Internal Upgrades

Internally GeoServer has received a number of important upgrades:

• Update to Spring 4: The upgrade to Spring 4 is responsible for the delay of the GeoServer 2.9 and was required for Java 8 compatibility. This upgrade was far reaching with both  the REST-API and Security integration requiring a concerted quality assurance effort on geoserver-devel. This upgrade was technically challenging resulting in a delay to the 2.9 release schedule. Thanks to everyone who helped out, beta testers, and Justin, Andrea and Niels for tackling the harder issues.

• Upgrade to JAI-EXT to 1.0.9: To enable JAI-EXT use startup parameter org.geotools.coverage.jaiext.enabled=true (for more information see Image Processing in the user guide).

• **Upgrade to Wicket 7: **The web administration application has been updated to use the latest Wicket library, thanks to a larger team effort. We would like to thank the sponsors of the Wicket 7 upgrade sprint: OSGeo, Boundless, Vivid Solutions, How 2 Map, San Jose Water Company, Transient, Geobeyond (with in-kind sponsors GeoSolutions, CCRi, Astun Technology and Voyager).

• The GeoServer default data directory has been updated with titles and descriptions for many layers (to better take advantage of the user interface improvements). The previously disabled Pk50095 layer (shown below) is now enabled by default.

##

The GeoServer team is pleased to announce GeoServer 2.9-RC1. Downloads are available (zip, war, dmg and exe) along with docs and extensions.

This release is made by Torben Barsballe (Boundless) in conjunction with GeoWebCache 1.9-RC1 and GeoTools 15-RC1.

This is a release candidate for final testing before we release 2.9.0.

Highlights:

• This release requires Java 8 and is compatible with Oracle JDK and OpenJDK

• GeoServer now requires Servlet 3 (so Tomcat 7 or newer if you are doing a WAR install)

• Update to Spring 4 and JAI-EXT to 1.0.9

• For more information, check the 2.9-beta, 2.9-beta2, and 2.9-M0 release notes.

Fixes since beta:

• Naming geoserver layer differently from underlying postgis table causes aggregates to be omitted in SQL queries supporting time dimension in GetCapabilities and related operations.

• Web interface does not reflect workspace specific WPS enabled/disabled properly

• Enabling WPS for a workspace doesn’t appear on the GUI after reload

• WPS workspace specific configurations fails to load

• Drag and drop rules in GeoFence not working

• Restricting security on layers breaks aggregate visitor optimizations in JDBC stores

• Stacktrace when modifying the configuration of a WMS Cascade layer

• Update jetty version used by windows installer service wrapper

• Stacktrace with unsupported option in GWC Memory Blobstore

• PDF generation can contain invalid polygons whose fill bleeds out in the whole map

For more information see 2.9-RC1 release notes.

GeoServer Community

GeoServer Community modules provide an area for ideas and experimentation. Community highlights for this release:

• Community YSLD: The YSLD styling language provides a more concise alternative to SLD, while still sharing the same structure.

Community modules should be considered a work-in-progress and are subject to quality assurance, documentation IP checks and a maintainer before being considered ready for release.

The GeoServer team is pleased to announce the release of GeoServer 2.9-beta2. The previous 2.9-beta discovered an incompatibility with Java 8, resulting in a bit of emergency planning and a delay to the 2.9.0 release schedule.

Download bundles are available (zip, war, dmg and exe). A reminder that beta releases are intended for public feedback and are not recommended for production use.

Highlights:

• This release requires Java 8 and is compatible with Oracle JDK and OpenJDK

• GeoServer now requires Servlet 3 (so Tomcat 7 or newer if you are doing a WAR install)

• Negative-date now supported (for GeoNode compatibility)

• New REST API for installation status

• For more information check the release notes for beta2 (history beta1

  M0)

• Update to Spring 4 and JAI-EXT to 1.0.9

This 2.9-beta2 release is released in conjunction with GeoTools 15-beta2 and GeoWebCache 1.9-beta2. Thanks to Jody Garnett (Boundless) and Kevin Smith (Boundless) for this release.

Beta Testing

The GeoServer Team has been hard at work to bring you this beta release. Thanks to the committers for taking part in the emergency spring-4 upgrade and community members joining for subsequent testing and quality assurance: Justin Deoliveira and Andrea Aimie, Emanuele Tajariol, Damiano Giampaoli, Ben Caradoc-Davies, Niels Charlier, Mauro Bartolomeoli, Jody Garnett, Jukka Rahkonen, Brad Hards, Kevin Smith, Chris Snider, Torben Barsballe, Christian Mueller, Luigi Pirelli  … and next you!

Here is our priorities for testing:

• Seeking confirmation on Java 8 compatibility (test Oracle JDK and OpenJDK on a range of platforms)

• Testing of the user-interface (although the team has performed extensive manual testing we need your help)

• Release packaging (check for anything out of date, any issues starting up)

• GeoServer security integration

We have a couple known issues to keep in mind when testing:

• Windows installer “Install as service” needs a configuration change once installed (GEOS-7507) Open wrapper.conf and update contents with: wrapper.app.parameter.1=org.eclipse.jetty.start.Main

• Windows installer “Run manually” may have an issue with startup.bat (GEOS-7509)

• Several issues have been reported with the Demo Page (GEOS-7513)
