If you are using maven GeoTools 2.7.2 is available from the OSGeo repository.
This is a bug fix release made in conjunction with GeoServer 2.1.1.
This is primarily a maintenance release focused on improving GeoTools 2.7 and is not devoted to new features. However a few call out to recognise some excellent work:
A long standing glitch in rendering line patterns was resolved; and GeoTools has been updated to work with PostGIS 2.0. Thanks Andrea and GeoSolutions for both of these fixes.
Thanks to Ben for back porting EMF 2.6.1 to the stable branch.
