The GeoServer team is happy to announce to the release of GeoServer 2.2
and encourage you to download it and try out the great new features.
The release of a new major version update is a big deal (the last one
was over 16 months ago) and, while you may have heard about some of the
new features on the developer list, here are the highlights all in one
place:

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. Thanks to Oscar Fonts and Andrea Aime.

- Continued work for supporting high accuracy datum transformations
that now allow for user defined transformations supplied via WKT.
Thanks to the Catalan Cartographic Institute for funding the work and
to Oscar and Andrea for doing the development.
- 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. Thanks Andrea.
- 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. Thanks to Justin Deoliveira and Andrea.
- A new lenient capabilities mode that allows the GeoServer
capabilities documents to remain functioning despite the presence of
misconfigured layers. Thanks to David Winslow for this work.
- 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. Thanks to Rini
Angreani, Niels Charlier, Victor Tey, Ben Caradoc-Davies, and the rest
of the team at CSIRO. 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. This is a continuation of work
started by Christian Mueller as a Google Summer of Code project; thanks
to NOAA for sponsoring OpenGeo to help Christian and Justin bring it to
completion.
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. Thanks
to IGN France for sponsoring OpenGeo to make this improvement.
- 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. Thanks to Andrea, Alessio and
GeoSolutions on both counts.
- Rendering transformations provide a bridge between WPS and WMS and
allow for very powerful visualization capabilities for processing
through normal WMS. Thanks to GeoSolutions for sponsoring this work
(and Andrea for implementing it).
- 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. Thanks to NOAA for sponsoring OpenGeo to complete
this improvement and a special thanks to Micah Wengren of NOAA for his
leadership on the project.
- 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. Big thanks to Gabriel and the GeoWebCache team for furthering
improving integration between GeoWebCache in GeoServer.
Wow! And that isn’t even everything, many other bug fixes and
improvements have made it into the 2.2 series as well.

Everyone who uses GeoServer should have at least one or two items in
the above list to be excited about. Download GeoServer 2.2, try it out,
and provide feedback on the GeoServer mailing list. As with any new
version, be sure to backup your data directory before upgrading.

Thanks again for using GeoServer!
