This is a release candidate release of GeoServer made in conjunction with
GeoTools 18-RC1.
We want to encourage people to test the release thoroughly and report back
any issue found. With no further delay, let’s see what’s new, that is, what
is there to test!
Rest API now using Spring MVC
In March
<http://blog.geoserver.org/2017/04/11/rest-api-code-sprint-results/>, 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
<http://docs.geoserver.org/latest/en/user/rest/index.html#rest>, providing
detailed information about each endpoint.
Thanks again to the code sprint sponsors:

WMTS Cascading
Adds the ability to create WMS layers backed by remote WMTS layers, similar
to the pre-existing WMS cascading functionality.
See GSIP-162 <https://github.com/geoserver/geoserver/wiki/GSIP-162> for
more details.

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.
See GSIP-161 <https://github.com/geoserver/geoserver/wiki/GSIP-161> for
more details.
<http://blog.geoserver.org/wp-content/uploads/2017/09/gsip161-ui.png>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:
&format_options=kmcentroid_contain:true;kmcentroid_samples:10;kmcentroid_clip:true
See GSIP-160 <https://github.com/geoserver/geoserver/wiki/GSIP-160> for
more details.
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.
See GSIP 159 <https://github.com/geoserver/geoserver/wiki/GSIP-159> for
more details.
NetCDF output support for variable attributes and extra variables
Adds the following to the NetCDF output extension:
1. An option to allow all attributes to be copied from the source
NetCDF/GRIB variable to the target variable.
2. Support for manual configuration of variable attributes, much like
the current support for setting global attributes.
3. 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.
See GSIP 158 <https://github.com/geoserver/geoserver/wiki/GSIP-158> for
more details.

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 <https://en.wikipedia.org/wiki/Kerning> is on by default
- New vendor option to strikethrough text
- New vendor options to control char and word spacing
[image: ../../../_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):
<http://blog.geoserver.org/wp-content/uploads/2017/09/border.png>
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:
<http://blog.geoserver.org/wp-content/uploads/2017/09/css_completion.png>
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):
<http://blog.geoserver.org/wp-content/uploads/2017/09/before_dateline.png>
<http://blog.geoserver.org/wp-content/uploads/2017/09/after_dateline.png>
<http://blog.geoserver.org/wp-content/uploads/2017/09/mosaic_dateline.png>
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
<http://docs.geoserver.org/latest/en/user/styling/mbstyle/index.html>
- For those into Earth Observation, there is a new OpenSearch for EO
module
<http://docs.geoserver.org/latest/en/user/community/opensearch-eo/index.html>
in
the community section
- Need to store full GeoTiff in Amazon S3? The “S3 support for GeoTiff
<http://docs.geoserver.org/latest/en/user/community/s3-geotiff/index.html>”
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
<https://github.com/geoserver/geoserver/pull/2518> to follow its
progress and merge.
Mind, community modules are not part of the release, but you can find them
in the nightly builds <http://geoserver.org/release/2.12.x/> instead.
