The GeoTools team is pleased to announce GeoTools 15.0!
This release is also available from our Maven repository. Java 8 is now required, please view the install guide for details. This release is made by Jody Garnett and Devon Tucker (Boundless) in conjunction with GeoWebCache 1.9.0 and GeoServer 2.9.0

Features and improvements

    Java 8

    As previously mentioned GeoTools 15.0 now requires Java 8, meaning GeoTools developers get to use all its fun new features. Projects are advised to update their Maven POM in order to use Java 8 features:
                <plugin>
                    <inherited>true</inherited>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                    </configuration>
                </plugin>
    


    GroupByVisitor 

    A new FeatureCollection aggregation visitor has been added: GroupByVisitor which behaves like the SQL Group By clause:
    SimpleFeatureType buildingType = ...;
    FeatureCollection featureCollection = ...;
    
    GroupByVisitor visitor = new GroupByVisitorBuilder()
                      .withAggregateAttribute("energy_consumption", buildingType)
                      .withAggregateVisitor("Average")
                      .withGroupByAttribute("building_type", buildingType)
                      .build();
    
    featureCollection.accepts(visitor, new NullProgressListener());
    
    CalcResult result = visitor.getResult();

    Perpendicular Offset

    Perpendicular offset styling is now available for lines.
           
           <LineSymbolizer>
             <Stroke>
               <CssParameter name="stroke">#FF0000</CssParameter>
               <CssParameter name="stroke-dasharray">5 2</CssParameter>
             </Stroke>
             <PerpendicularOffset>5</PerpendicularOffset>
           </LineSymbolizer>

      2. Darn I was all excited. The new ScrollWheelClass does not exist in gt-swing 15.0 :( The merge of that PR appears to have happened a just after the release was cut.

        https://github.com/geotools/geotools/pull/1178

        So I think the following line should be removed from the release notes, unless I'm confusing it with some other feature?

        "Allow users to zoom in and out using the mouse scroll wheel in JMapPane"
