About GeoTools 9.1
This is our first dot release on the 9.1 series and is focused on bug fixes and stability. This release is made in conjunction with GeoServer 2.3.1. 
Headline improvement is support for SQL Server native geometry serialisation (https://github.com/geotools/geotools/pull/174). The fix (https://jira.codehaus.org/browse/GEOT-4442) was supplied by Anders Bakkevold and is expected to have a huge impact on performance. This work was sponsored by Norwegian Directorate for Nature Management and performed by Bouvert (http://www.bouvet.no/).
SQL Server also got a fix (https://jira.codehaus.org/browse/GEOT-4428) to make native paging optional.
Thanks to Dieter DePaepe for fixing (https://github.com/geotools/geotools/pull/134) GEOT-2791 (https://jira.codehaus.org/browse/GEOT-2791), addressing a long standing issue working with sparse shapefiles.
Thanks to Frank Warmerdam for submitting a fix (https://jira.codehaus.org/browse/GEOT-4433) to distance calculations used when testing map projects. Frank was also kind enough to write a blog post  (http://fwarmerdam.blogspot.com.au/2013/03/getting-started-with-geotools.html)covering his experience fixing GeoTools.
Improvements to Arc parsing in GML (https://jira.codehaus.org/browse/GEOT-4018) were provided by Jira Novak.
Shane StClair has added UUID mappings (https://jira.codehaus.org/browse/GEOT-4414) to PostGIS.
Finally thanks to Simone who has addressed an annoying colour space issue (https://jira.codehaus.org/browse/GEOT-4450) on recent windows installations.

Thanks to all our volunteers on GitHub and the dedicated community members reviewing pull requests. A reminder to include a test-case with any proposed fix so we can smoothly review your work.
