New in GeoServer 2.19.0 (Mar 22, 2021)

New in GeoServer 2.16.0 (Sep 19, 2019)

New in GeoServer 2.15.0 (Mar 1, 2019)

New in GeoServer 2.14.2 (Jan 28, 2019)

New in GeoServer 2.14.0 (Sep 24, 2018)

WMS “nearest match” support for time dimension:
WMS time dimension can now be configured for “nearest match”, that is, to return the nearest time to the one requested (either explicitly, or implicitly via the default time value).
In case of mismatch the actual time used will be returned along with the response as a HTTP header. It is also possible to configure a maximum tolerance, beyond that the server will throw a service exception.
Channel selection name allow expressions:
GeoServer 2.14-RC allows expressions to be used in SourceChannelName SLD elements, and in their code counterpart, thus allowing dynamic channel selection. This is welcomed news for anyone building applications that display multispectral or hyperspectral data, thus avoiding the need to build many different styles for the various interesting false color combinations.
Here is an SLD example:
<RasterSymbolizer>
<ChannelSelection>
<RedChannel>
<SourceChannelName>
<ogc:Function name="env">
<ogc:Literal>B1</ogc:Literal>
<ogc:Literal>2</ogc:Literal>
</ogc:Function>
</SourceChannelName>
</RedChannel>
<GreenChannel>
<SourceChannelName>
<ogc:Function name="env">
<ogc:Literal>B2</ogc:Literal>
<ogc:Literal>5</ogc:Literal>
</ogc:Function>
</SourceChannelName>
</GreenChannel>
<BlueChannel>
<SourceChannelName>
<ogc:Function name="env">
<ogc:Literal>B3</ogc:Literal>
<ogc:Literal>7</ogc:Literal>
</ogc:Function>
</SourceChannelName>
</BlueChannel>
</ChannelSelection>
<RasterSymbolizer>
Map algebra:
This release adds support for an efficient map algebra package knows as Jiffle. Jiffle has been the work of a former GeoTools contributor, Michael Bedwards, that has been salvaged, upgraded to support Java 8, and integrated in jai-ext. From the there support has been added into the GeoTools gt-process-raster module and as a result in GeoServer WPS, to be used either directly or as a rendering transformation.
he following SLD style calls onto Jiffle to perform a NDVI calculation on top of Sentinel 2 data:

PostGIS store improvements and measured geometries support:
The PostGIS datastore has been for years the only one that could encode a few filter functions used in filters down into native SQL, but it required a datastore creation flag to be enabled.
Starting with this release it will do so by default.
The functions supported for SQL encoding by the store are:
String functions: strConcat, strEndsWith, strStartsWith, strEqualsIgnoreCase, strIndexOf, strLength, strToLowerCase, strToUpperCase, strReplace, strSubstring, strSubstringStart, strTrim, strTrim2
Math functions: abs, abs_2, abs_3, abs_4, ceil, floor
Date functions: dateDifference
This release adds support for “array” data type in the store, with full reading and writing support, as well as native filtering (with index support, where feasible).
Finally, it’s now possible to read geometries with measures from PostGIS and encode the results in GML. GML does not natively support measures, so the encoding is off by default and you’ll have to enable it explicitly, as well as ensure that the clients involved in WFS usage recognize this extra ordinate. The work will continue in the next few month in order to cover more formats.
Image mosaic improvements:
The image mosaic module never sleeps, in this release we see the following improvements:
Support for remote images (e.g. S3 or Minio). In order to leverage this the mosaic index will have to be created up-front (manually, or with some home grown tools)
A new “virtual native resolution” read parameter allows the mosaic to compose outputs respecting a native resolution other than its native one (useful in case you want to give selective resolution access to different users)
Supporting multiple WKBs footprint for pixel precise overviews masking
A new read mask parameter allows to cut the image to a given geometry (again, helps in providing different selective views to different users)
Speed up NetCDF mosaics by allowing usage of stores coming from a repository, instead of re-creating them every time a NetCDF file is needed (to be setup in the auxiliary store config file, while the repository instance needs to be passed as a creation hint).
The mosaic now works against images without a proper CRS, setting them into the “CRS not found” wildcard CRS, aka “EPSG:404000”
App-schema improvements:
The app-schema module got significant performance and functionality improvements since 19.x series, in particular:
Better delegation of spatial filters on nested properties to native database
Improved support for multiple nested attribute matches in filters
It is now possible to use Apache SOLR as a data source for app-schema
The configuration files can be hosted on a remote HTTP server
The MongoDB store upgrades to official extension:
Wanted to use the MongoDB store but worried about its unsupported status? Worry no more, in GeoServer 2.14 the MongoDB datastore upgraded to official extension status.
Style editor improvements:
The GeoServer style editor now includes a fullscreen side-by-side editing mode, to make it easier to preview your styles while editing them. Click the fullscreen button at the top-right of the screen to toggle fullscreen mode.
The toolbar also has two new additions, a color picker helping to find the right color and turn it into a HEX specification, and a file chooser that allows to pick an external graphic and build the relevant ExternalGraphic element.
Windows build restored:
GeoServer failed to properly build on Windows for a long time. GeoServer 2.14.x is the first branch in years to successfully build on Windows, and we have added an AppVeyor build to help keep the build going in the future.
The work to make it build there has been fully done in spare time, and we are still experiencing random build failures. If you are a Java developer on Windows, we could really use your help to keep GeoServer Windows build friendly.
New community modules:
The 2.12 series comes with a few new community modules, in particular:
OAuth2 OpenID connect module (still very much a work in progress)
A WFS3 implementation has been added that matches the current WFS3 specification draft, and it’s being updated to become an official compliant one.
Mind, community modules are not part of the release, but you can find them in the nightly builds instead.
Other assorted improvements:
There are many improvements to look at in the release notes, cherry picking a few here:
The ncWMS community module has seen significant performance improvements
WPS has a CSV input/output supporting geometryless data, as well as geometries with WKT encoding, as well as supporting pure PNG/JPEG image for raster data
Time/Elevation parsers are no longer silently cutting the read data to 100 entries
The WMTS multidimensional GetHistogram operation is now significantly faster, and a new GetDomainValues operation allows to page through the values of a domain (time, elevation) that has too many values to be efficiently explored with DescribeDomain or GetFeature. The DescribeDomain was also improved to allow a selection of the domains that should be described.
The SLDService community module has now the ability to return a full SLD style (as opposed to snippets), allows for custom classification and custom color selection. Also, keep an eye on this module, as it’s about to graduate to supported status
The monitoring modul can now log the hit/miss status of tiled requests, quite helpful to verify the benefit of caching, especially while using WMS direct integration
Security consideration:
Please update your production instances of GeoServer to receive the latest security updates and fixes.
This release addresses several security vulnerabilities:
Prevent arbitrary code execution via Freemarker Template injection
XXE vulnerability in GeoTools XML Parser
XXE vulnerability in WPS Request builder
Various library upgrades (see above) from versions with known CVEs
Potential access to admin pages without being logged in

New in GeoServer 2.13.2 (Jul 24, 2018)

New in GeoServer 2.13 Beta (Feb 22, 2018)

Isolated Workspaces:
The concept of an “Isolated Workspaces” has been added to GeoServer, to allow for reusing a namespace among multiple workspaces. In particular, an isolated workspace allows reuse of a namespace already used by another workspace, but its resources (layers, styles, etc …) can only be retrieved when using that workspace’s virtual services and will only show up in those virtual service capabilities documents.
When reusing a namespace among workspaces, exactly one of those must be non-isolated, and the rest must be isolated; i.e. isolated workspaces have no restrictions in namespaces usage but the existing restrictions still apply for non isolated workspaces.
GeoWebCache REST API:
Two new endpoints have been added to the GeoWebCache REST API:
/gwc/rest/blobstores:
GET /gwc/rest/blobstores for a list of the blobstores
GET /gwc/rest/blobstores/{blobStoreName} for details about a single blobstore
PUT /gwc/rest/blobstores/{blobStoreName} to create or update a blobstore
DELETE /gwc/rest/blobstores/{blobStoreName} to remove a blobstore
/gwc/rest/gridsets:
GET /gwc/rest/gridsets for a list of the gridsets
GET /gwc/rest/gridsets/{gridSetName} for details about a single gridset
PUT /gwc/rest/gridsets/{gridSetName} to create or update a gridset
DELETE /gwc/rest/gridsets/{gridSetName} to remove a gridset
API docs for these endpoints will be added to the GeoServer documentation shortly. Until then, the request body syntax for PUT requests closely matched the equivalent structures in geowebcache.xml: BlobStores and GridSets.
The ArcGISCache backed layers are now also configurable via the REST API:
This release sees a major reworking of the configuration system in GeoWebCache that will allow for plugging in alternate configuration persistence mechanisms in future. While these changes should be largely invisible to users, it is a huge update that impacts all of GeoWebCache. However, due to these changes, we ask that you please test the embedded GeoWebCache.
UI Improvements:
Entering in URLs for data files has been improved with autocomplete – now GeoServer will scan the path that has already been typed, and suggest existing files within that path.
In addition, autocomplete support has been added to a number of dropdowns which contain a long list of values, such as stores or layers. You can now start typing the name of an option, and the visible options will be filtered to match.
Removed OS X installers:
Due to lack of resources and interest, the OS X dmg installers are no longer being built. OS X users can still use the system-independent binary.
New community modules:
The 2.13 series comes with a few new community modules, in particular:
Do you want to generate GHRSST compliant outputs from GHRSST inputs? Try out the new GHRSST NetCDF output community module.
There is also a new community module introducing NSG profiles for the WFS and WMTS services.
Not that community modules are not part of the release; instead you can find them in the nightly builds.
Other assorted improvements:
There are many bug fixes and improvements to look at in the release notes, cherry picking a few here:
Autocomplete support for dropdowns with long lists of values
Upgrade JDom library
REST API CORS support
REST improvements to list all layers in a workspace, and include the workspace prefix in layer listings
Style POST does not support non-SLD styles
Add WMTS RESTful API
Installing the XSLT plugin may cause random REST endpoints to report lists with transforms/transform

GeoPackage generated via WPS has y coordinates starting from bottom left
Numerous WFS 2.0 bugfixes
Submitting a seed/truncate request for a tile layer results in a “406, not acceptable”
GWC Seed Form returns “Chunk [] is not a valid entry” message error when seeding a layer.
Demo Page does not send password

New in GeoServer 2.12.2 (Jan 25, 2018)

New in GeoServer 2.12.1 (Nov 22, 2017)

New in GeoServer 2.12 RC 1 (Sep 30, 2017)

Rest API now using Spring MVC:
In March, we upgraded the framework used by the GeoServer REST API from Restlet to Spring MVC. All the endpoints should remain unchanged, but they do need testing to ensure there weren’t any unintended side effects.
As part of this upgrade, we also have new REST documentation, providing detailed information about each endpoint.

WMTS Cascading:
Adds the ability to create WMS layers backed by remote WMTS layers, similar to the pre-existing WMS cascading functionality.
Style Based Layer Groups:
Adds the ability to define a listing of layers and styles using a single SLD file, in accordance with the original vision of the SLD specification. This includes a new entry type in the Layer Group layers list, and a new preview mode for the style editor.
Options for KML Placemark placement:
New options for KML encoding have been added, to control the placement of placemark icons, mostly for polygons. The syntax of the new options introduces three new top level format options keys
GeoWebCache data security API:
Add an extension point to GeoWebCache allowing for a security check based on the layer and extent of the tile. Adds an implementation of this extension point to GeoServer’s GWC integration.
This change mostly only affects developers, but will lead to improved security for users in the future.
NetCDF output support for variable attributes and extra variables:
Adds the following to the NetCDF output extension:
An option to allow all attributes to be copied from the source NetCDF/GRIB variable to the target variable.
Support for manual configuration of variable attributes, much like the current support for setting global attributes.
Support for configuration of extra variables which are copied from the NetCDF/GRIB source to the output; initially only scalar variables will be supported. Extra variables can be expanded over “higher” dimensions, that is, values copied from one scalar per ImageMosaic granule are assembled into a multidimensional variable over, for example, time and elevation.
New labeling features and QGIS compatibility:
A number of small new features have been added to labeling to match some of QGIS features, in particular:
Kerning is on by default
New vendor option to strikethrough text
New vendor options to control char and word spacing
../../../_images/charSpacing.png
Perpendicular offset now works also for curved labels (previously only supported for straight labels):
Labeling the border of polygons as opposed to their centroid when using a LinePlacement (here with repetition and offset):
Along with this work some SLD 1.1 text symbolizer fixes were added in order to better support the new QGIS 3.0 label export, here is an example of a map labeling with background image, as shown in QGIS, and then again in GeoServer using the same data and the exported SLD 1.1 style (click to enlarge):
CSS improvements:
The CSS styling language and editing UI have seen various improvements. The editor now supports some primitive code completion:
At the language level:
Scale dependencies can now also be expressed using the “@sd” variable (scale denominator) and the values can use common suffixes such as k and M to get more readable values, compare for example “[@scale < 1000000]” with “[@sd < 1M]”
Color functions have been introduced to match LessCSS functionality, like “Darken”, “Lighten, “Saturate” and so on. The same functions have been made available in all other styling languages.
Calling a “env” variable has been made easier, from “env(‘varName’)” to “@varName” (or “@varName(defaultValue)” if you want to provide a default value).
As you probably already know, internally CSS is translated to an equivalent SLD for map rendering purposes. This translation process became 50 times faster over large stylesheets (such as OSM roads, a particularly long and complicated style).
Image mosaic improvements and protocol control
Image mosaic saw several improvements in 2.12.:
First, the support for mosaicking images in different coordinate reference systems improved greatly, with several tweaks and correctness fixes. As a noteworthy change, the code can now handle source data crossing the dateline. The following images show the footprints of images before and after the dateline (expressed in two different UTM zones, 60 and 1 respectively) and the result of mosaicking them as rasters (click to get a larger picture of each):
There are more good news for those that handle mosaicks with a lot of super-imposing images taken at different times. If you added interesting information into the mosaic index, such as cloud cover, off-nadir, snow cover and the like, you can now filter and sort over them, in both WMS (viewing) and WCS (downloading) by adding the cql_filter and sortBy KVP parameters.
Here is an example of the same mosaic, the first composite favoring smallest cloud cover, the second one favoring recency instead (click to enlarge):
GeoPackage graduation:
The GeoPackage store jumped straight from community to core package, in light of its increasing importance.
The WMS/WFS/WPS output formats are still part of community. Currently GeoPackage vector does not support spatial indexes, but stay tuned, it’s cooking!
New community modules
The 2.12 series comes with a few new community modules, in particular:
Looking into styling vector tiles and server side using a single language? Look no further than the MBStyle module
For those into Earth Observation, there is a new OpenSearch for EO module in the community section
Need to store full GeoTiff in Amazon S3? The “S3 support for GeoTiff” module might just be what you’re looking for
A new “status-monitoring” community module has been added, providing basic statistics system resource usage. Check out this pull request to follow its progress and merge.
Mind, community modules are not part of the release, but you can find them in the nightly builds instead.
Other assorted improvements:
Users REST uses default role service name as a user/group service name
imageio-ext-gdal-bindings-xxx.jar not available in geoserver-2.x.x-gdal-plugin.zip anymore since 2.10

Security Considerations:
This release includes several security enhancements (which are also included in the recent GeoServer 2.8.5 and 2.9.1 releases
Although we have not been able to reproduce from GeoServer, a remote execution vulnerability has been reported against both the Restlet and the Apache Commons BeanUtils libraries we use. We have patched our use of these libraries as a preventative measure. We would like to thank Kevin Smith for doing the bulk of the work, and Andrea Aime for providing a patched BeanUtils library addressing these vulnerabilities.
Layer security restrictions in CHALLENGE mode were not being correctly applied by embedded GeoWebCache. Thanks to Nick Muerdter for his responsible report of this vulnerability and for submitting a fix (that included a unit test!)
Carl Schroedl reported a vulnerability at application startup when working with a data directory on a network file system, a new configuration option has been provided to check that the directory exists. Thanks to Carl for following our responsible disclosure procedure, and to Ben Caradoc-Davies for implementing the new parameter.

New in GeoServer 2.8.0 (Oct 24, 2015)

GeoServer 2.8.0 is the culmination of our latest six month development cycle and contains several new features, along with fixes and security updates.
This blog post provides a breakdown by functional area, for more detail see the 2.8.0, 2.8-beta and 2.8-M0 release notes.
Data access and configuration
PostGIS curves and Oracle speedups
GeoServer 2.6.0, released one year ago, added read only support for Oracle curved geometries, along with all the necessary machinery to represent them in memory, draw them and encode them in WMS.
This release adds read and write support for curves in PostGIS instead, bringing our support for the famous open source spatial database to match and surpass (with write support) the Oracle one. PostGIS curves are supported in all OGC protocols, either via native support (e.g., GML) or on the fly linearization (e.g. shapefile output).
Sample curve data for PostGIS:
On the Oracle side, we improved the startup times for installation that are serving of Oracle layers by optimizing the table geometry type and metadata access.
Note: Due to license restrictions the oracle extension no longer includes an Oracle JDBC driver, see the user guide for manual install instructions.
Filtering layers during configuration
For all those that want to publish only a subset of the original data to the public we are now offering the configuration of a simple CQL filter that will be applied on data access, no matter what protocol is used. Think of it as a mini “sql view” that can be applied at ease against any data source, not just databases.
../../_images/data_layers_cql.png
Layer CQL Filter:
This is of course not meant to limit feature access for security reasons, for that use case you should really look into GeoFence.
Raster NODATA with JAI-Ext Library
You may now optionally use the JAI-Ext image processing operations when working with raster data. These operations directly support raster NODATA and footprints (reducing the amount of processing required when working with these datasets).
JAI-Ext Operations
JAI-Ext Operations
REST API for Image Moasic Granule Management:
Structured coverages have recently been added to GeoServer, you can now use the REST API to manage and update individual granules in an image mosaic.
Process raster data during import:
Vector import has supported limited data processing during import for some time. GeoServer 2.8.0 provides the same functionality (allowing raster files to be processed using GDAL command line tools during import).
Mapping improvements:
This release is full of big and small map rendering improvements for all. Here is an organized list.
Z ordering support:
This new features extends SLD and CSS with vendor options allowing the style writer to control the painting order of features, either inside a single layer, or across layers: this allows proper map rendering of areas where a number of objects have below/above relationsthips, like this area in Germany, where a lot of roads and rails are crossing each other in a maze of underpasses, overpasses, and bridges.
z-order example:
This is achieved by specifying a “sortBy” vendor option at the FeatureTypeStyle level, with one or more sorting attributes, and in case multiple layers or FeatureTypeStyles are involved, by grouping them into a single “sortByGroup”. You can find more information, along with examples in CSS and SLD, in your user guide.
We would like to thank DLR for sponsoring this improvement.
Constrast enhancement improved:
GeoServer has been supporting contrast enhancement for a while, within the limits of the SLD specification. Version 2.8.0 steps beyond the limits of the standard by adding vendor parameters to control the normalization sub-algorithm (stretch to min/max, clip to min/max, clip to zero), as well as its parameters. Here is an example of the syntax.
New arrow mark:
Lots of map needs arrows… but every time is the same story, yes, the arrow is almost fine, but it should be longer, or thicker, or with a bigger head, and so on. Instead of having to re-invent a new arrow symbol each time, we created one whose proportions can be altered by changing parameters in its name.
GeoServer 2.8.0 improves its support for maps in multiple scripts, which can be a source of headaches. While it’s often easy to find support for most scripts in fonts, it’s hard to get one that would support, for example, western languages, arabic, corean, indi and simplified chinese in a single package. Especially for scripts like simplified chinese you have to resort to custom fonts.
Now, what happens if you are labelling a map that contains them all, and sometimes, contains more than one of them in a single label? Before GeoServer 2.8.0 we did not have a great answer to that, but now, you can simply specify multiple fonts in a TextSymbolizer, and the most suitable one will be chosen on the fly, eventually using multiple fonts in a single label in case there is no one able to handle the whole of it. Here is an example with mixed script labels:
Selezione_072
Multi-script Support:
We would like to thank DLR for sponsoring this improvement.
Improved labeling density:
Before GeoServer 2.8.0 labelling dense road networks with lots of diagonal and curved labels might have left the impression that more labels could have fit the map… and that was not just an impression! Indeed, the previous label algorithm was reserving a busy area for the bounding box containing the label, which as you may see, is a lot more space than the actual label occupancy:
Letter reservation - conflict:
The French National Institute for geographic information provided a patch that makes the single chars of diagonal or curved labels be reserved instead, resulting in maps with quite a bit more labelled items per square inch:
tiger-tiger_roads (1)
Improved Label Density:
WMS/WMTS protocol and configuration improvements
Creating new styles from templates:
It’s now possible to create new styles starting from the built-in templates, and the style will be encoded in the desired style language (SLD, or CSS, or even something else, if you created your own styling language extension point):
../../_images/data_style_editor_generate.png
Generate Default Style:
GeoWebCache filter parameters GUI improved
It’s now possible to configure integer parameters in the caching section of a layer configuration.
Parameter Filter
GeoWebCache Storage
GeoWebCache can now store cached tiles on a perlayer basis – including Amazon S3.
tile storage:
Request parameter support in Freemaker templates
Freemarker GetFeatureInfo templates can now access to the request parameter, as well as the Java process environment variables, in order to customize their response. For example, it’s now possible to expand the following variables in the template:
${request.LAYERS}
${request.ENV.PROPERTY}
${environment.GEOSERVER_DATA_DIR}
${environment.WEB_SITE_URL}
Controlling interpolation on a layer by layer basis:
You can now control layer interpolation via GetMap, and specify a different interpolation policy on different layers. This is great if you are serving multiple raster maps, and maybe you want to have your classified raster use nearest neighbor, while showing the ozone density layer with bilinear interpolation.
Inspire configuration improved

New in GeoServer 2.7.1.1 (Oct 24, 2015)

GeoServer 2.8.0 is the culmination of our latest six month development cycle and contains several new features, along with fixes and security updates.
This blog post provides a breakdown by functional area, for more detail see the 2.8.0, 2.8-beta and 2.8-M0 release notes.
Data access and configuration
PostGIS curves and Oracle speedups
GeoServer 2.6.0, released one year ago, added read only support for Oracle curved geometries, along with all the necessary machinery to represent them in memory, draw them and encode them in WMS.
This release adds read and write support for curves in PostGIS instead, bringing our support for the famous open source spatial database to match and surpass (with write support) the Oracle one. PostGIS curves are supported in all OGC protocols, either via native support (e.g., GML) or on the fly linearization (e.g. shapefile output).
Sample curve data for PostGIS:
On the Oracle side, we improved the startup times for installation that are serving of Oracle layers by optimizing the table geometry type and metadata access.
Note: Due to license restrictions the oracle extension no longer includes an Oracle JDBC driver, see the user guide for manual install instructions.
Filtering layers during configuration
For all those that want to publish only a subset of the original data to the public we are now offering the configuration of a simple CQL filter that will be applied on data access, no matter what protocol is used. Think of it as a mini “sql view” that can be applied at ease against any data source, not just databases.
../../_images/data_layers_cql.png
Layer CQL Filter:
This is of course not meant to limit feature access for security reasons, for that use case you should really look into GeoFence.
Raster NODATA with JAI-Ext Library
You may now optionally use the JAI-Ext image processing operations when working with raster data. These operations directly support raster NODATA and footprints (reducing the amount of processing required when working with these datasets).
JAI-Ext Operations
JAI-Ext Operations
REST API for Image Moasic Granule Management:
Structured coverages have recently been added to GeoServer, you can now use the REST API to manage and update individual granules in an image mosaic.
Process raster data during import:
Vector import has supported limited data processing during import for some time. GeoServer 2.8.0 provides the same functionality (allowing raster files to be processed using GDAL command line tools during import).
Mapping improvements:
This release is full of big and small map rendering improvements for all. Here is an organized list.
Z ordering support:
This new features extends SLD and CSS with vendor options allowing the style writer to control the painting order of features, either inside a single layer, or across layers: this allows proper map rendering of areas where a number of objects have below/above relationsthips, like this area in Germany, where a lot of roads and rails are crossing each other in a maze of underpasses, overpasses, and bridges.
z-order example:
This is achieved by specifying a “sortBy” vendor option at the FeatureTypeStyle level, with one or more sorting attributes, and in case multiple layers or FeatureTypeStyles are involved, by grouping them into a single “sortByGroup”. You can find more information, along with examples in CSS and SLD, in your user guide.
We would like to thank DLR for sponsoring this improvement.
Constrast enhancement improved:
GeoServer has been supporting contrast enhancement for a while, within the limits of the SLD specification. Version 2.8.0 steps beyond the limits of the standard by adding vendor parameters to control the normalization sub-algorithm (stretch to min/max, clip to min/max, clip to zero), as well as its parameters. Here is an example of the syntax.
New arrow mark:
Lots of map needs arrows… but every time is the same story, yes, the arrow is almost fine, but it should be longer, or thicker, or with a bigger head, and so on. Instead of having to re-invent a new arrow symbol each time, we created one whose proportions can be altered by changing parameters in its name.
GeoServer 2.8.0 improves its support for maps in multiple scripts, which can be a source of headaches. While it’s often easy to find support for most scripts in fonts, it’s hard to get one that would support, for example, western languages, arabic, corean, indi and simplified chinese in a single package. Especially for scripts like simplified chinese you have to resort to custom fonts.
Now, what happens if you are labelling a map that contains them all, and sometimes, contains more than one of them in a single label? Before GeoServer 2.8.0 we did not have a great answer to that, but now, you can simply specify multiple fonts in a TextSymbolizer, and the most suitable one will be chosen on the fly, eventually using multiple fonts in a single label in case there is no one able to handle the whole of it. Here is an example with mixed script labels:
Selezione_072
Multi-script Support:
We would like to thank DLR for sponsoring this improvement.
Improved labeling density:
Before GeoServer 2.8.0 labelling dense road networks with lots of diagonal and curved labels might have left the impression that more labels could have fit the map… and that was not just an impression! Indeed, the previous label algorithm was reserving a busy area for the bounding box containing the label, which as you may see, is a lot more space than the actual label occupancy:
Letter reservation - conflict:
The French National Institute for geographic information provided a patch that makes the single chars of diagonal or curved labels be reserved instead, resulting in maps with quite a bit more labelled items per square inch:
tiger-tiger_roads (1)
Improved Label Density:
WMS/WMTS protocol and configuration improvements
Creating new styles from templates:
It’s now possible to create new styles starting from the built-in templates, and the style will be encoded in the desired style language (SLD, or CSS, or even something else, if you created your own styling language extension point):
../../_images/data_style_editor_generate.png
Generate Default Style:
GeoWebCache filter parameters GUI improved
It’s now possible to configure integer parameters in the caching section of a layer configuration.
Parameter Filter
GeoWebCache Storage
GeoWebCache can now store cached tiles on a perlayer basis – including Amazon S3.
tile storage:
Request parameter support in Freemaker templates
Freemarker GetFeatureInfo templates can now access to the request parameter, as well as the Java process environment variables, in order to customize their response. For example, it’s now possible to expand the following variables in the template:
${request.LAYERS}
${request.ENV.PROPERTY}
${environment.GEOSERVER_DATA_DIR}
${environment.WEB_SITE_URL}
Controlling interpolation on a layer by layer basis:
You can now control layer interpolation via GetMap, and specify a different interpolation policy on different layers. This is great if you are serving multiple raster maps, and maybe you want to have your classified raster use nearest neighbor, while showing the ozone density layer with bilinear interpolation.
Inspire configuration improved
Security:
REST API for access control
Their is now a REST API for configuring security access control – see the user guide for details.

New in GeoServer 2.7.0 (Apr 1, 2015)

Color composition and color blending:
These are two new extensions to the rendering engine that allows for greater control over how overlapping layers in a map are merged together. Instead of just placing layers on top of others (with or without transparency), there is now a range of filters and effects, such as “multiply”, “darken”, and “hard light”.
Relative time support in WMS/WCS:
GeoServer has long had the ability to specify dates/times in requests to subset data. Up until now these dates/times needed to be absolute. Support has now been added for specifying relative time.
WPS clustering:
There are quite a few improvements to the Web Processing Service module, courtesy of Andrea Aime and GeoSolutions. (Please note that WPS is still an extension.)
GeoServer has a new WPS extension point allowing GeoServer nodes in the same cluster to share the status of current WPS requests. This is particularly important for asynchronous requests, as the client polling for the progress/results might not be hitting the same node that’s currently running the request.
This initial implementation leverages the Hazelcast library to share the information about the current process status using a replicated map.
WPS security
GeoServer now has the ability to connect WPS processes to the standard role-based security system. This means that administrators can now determine what users and groups can access or execute, making WPS usage safer and more secure.
WPS limits:
In addition to limiting the users and groups that can access WPS processes, GeoServer now also has the ability to set WPS input execution limits (such as timeout values), ensuring that a runaway process can’t cause a system to fail due to utilizing too many resources. Limits can be set globally and on a per-process basis.
WPS dismiss:
A client that connects to the WPS now not only has the ability to execute processes, but also the ability to dismiss/kill processes. Also new is the ability for the administrator to see the current processes that are being executed on the system.
CSS extension refresh:
The popular CSS extension, originally written by David Winslow of Boundless, allows users to style layers using a CSS-like syntax instead of SLD. This extension has now been entirely rewritten in native Java. The functionality remains the same, though with improvements in speed and stability.
New CSS workshop:
There is also now a full workshop-sized tutorial devoted to using CSS in GeoServer. This expands upon the basic tutorial, and goes into greater detail, providing a powerful learning resource for anyone who wants to learn how to style maps with CSS.
Cascade WFS Stored Queries:
Thanks to Sampo for adding support for cascaded WFS stored queries.

New in GeoServer 2.6.0 (Oct 25, 2014)

New and Improved
New functionality:
WFS Cascade: WFS Cascade has been updated to use a brand new GeoTools wfs client implementation.
Curve support for GML and WMS: GeoServer curve support has been added for interaction with Oracle Spatial. To configure look for Linearization tolerance when configuring your layer. As outlined in the FOSS4G presentation we are seeking interested parties to implement or fund curve support for PostGIS and SQL Server.
Advanced Projection Handling: Considerable care has been taken in the handling of raster data across the dateline and in polar projections.
Coverage Views: recombine bands from different sources into a multi-band coverage (use “configure new coverage view” when creating a new layer).
Vector footprints support in image mosaics: you can now cut out of your images the “bad” parts using vector footprints, setup as sidecar wkb/wkt files, or as a global footprints shapefile
Pluggable Styles: this change allows greater integration with the CSS Extension (and opens the door for even more style languages in the future)
Wind Barbs and WKT Graphics: for greater creative control.
Printing: new implementation from our friends at MapFish (based on MapFish 2.x).
Scripting community module: a great new editor for editing scripts directly from the web application
New raster formats: NetCDF and GRIB support, for anyone dealing with multidimensional data. NetCDF is also supported as a WCS output format, and it allows to extract data hypercubes out of your WCS server. Finally, it is also possible to build multidimensional mosaics of NetCDF and GRIB files, and add to the using the harvest REST API.
Language and Internationalisation: Turkish support has been added and French, Korean, Polish, Romanian are all caught up with the latest developments. Spot a translation mistake? Help translate here: GeoServer Latest localizations

Referencing:
NTv2 and NADCon Support allows for datum transformations with cm level precision (instead of the usual 4m, when all goes well). Both will activate only if the grid files are present in the data dir, so by default the mere presence of the method is harmless, but generally speaking this is very good news for whoever needs to increase reprojection accuracy.
Continued work for supporting high accuracy datum transformations that now allow for user defined transformations supplied via WKT.
A new reprojection console allows users to interactively test transformations of points and other geometries back and forth between the chosen CRS, and also to verify the transformation method used matches the user expectations.
Better support for un-referenced data with the new EPSG:40400 code that identifies a coordinate system made up of a generic 2D Cartesian plane. As well as support for EPSG:102113 as an alias for Web Mercator.
Data access:
Database-level security implements the ability to use DBMS session startup and teardown scripts to alter user access the database during a specific request while falling back on connection pooling when the request is complete. Thanks to Astrium GEO-Information Services for sponsoring GeoSolutions to make this improvement.
Sorting and paging is now available in all WFS versions (in 1.0 and 1.1 as a vendor param) via the sortBy and startIndex/maxFeature parameters.
A new lenient capabilities mode that allows the GeoServer capabilities documents to remain functioning despite the presence of misconfigured layers.
A new experimental OGR data store provides access to a rich set of readable formats without needing special bridge libraries.
The image collection coverage store allows users to serve un-referenced data through WMS using image/pixel space as the coordinate system. Thanks to SFMTA for sponsoring OpenGeo to complete this work.
Application schema support has performance, stability, and functional improvements including reduced memory footprint, SQL joining support for more efficient queries of complex information models, support for WMS, and support for GML 3.2 application schemas.
This work was funded through AuScope by the Australian Government.
BigTiff support has received some performance and scalability improvements courtesy of upgrade to imageio-ext 1.1.5.
Security:
A major retrofit of the GeoServer security subsystem adding support for a number of new authentication mechanisms including LDAP, digest and X.509 certificate authentication, and more. These improvements also includes the addition of user groups.
Web Feature Source (WFS):
Support for WFS 2.0 adds some interesting new capabilities to the WFS protocol such as paging, stored queries, and extended operators.
Along with WFS 2.0 comes support for GML 3.2.
Web Map Service (WMS):
Support for additional dimensions brings time and elevation support to both vector and raster data. And, with support for time, comes support for animation in WMS.
Rendering transformations provide a bridge between WPS and WMS and allow for very powerful visualization capabilities for processing through normal WMS.
Support for 8-bit PNG output with transparency resulting in a nice tradeoff of performance and appealing visualization. Special thanks to Andrea for this new feature.
Web Processing Service (WPS):
New WPS features include support for asynchronous process execution and a variety of new processes.
Virtual Services:
Virtual services allow GeoServer to support the notion of multitenancy, enabling a single GeoServer instance to publish multiple service endpoints.
Workspace local settings allow for specifying service settings such as contact information, proxy settings, and output format settings on a per workspace basis.
Styles and layer groups can also now be defined on a per workspace basis.
GeoWebCache:
A GeoWebCache configuration GUI is now available directly from within the GeoServer web admin interface, including: the ability to define new grid sets, specify which layers to cache, seed or truncate the cache, and more.
