Ontotext are pleased to announce the release of *OWLIM version 4.1* 
<http://www.ontotext.com/owlim>. This is a maintenance release of the 
OWLIM family <http://www.ontotext.com/owlim/editions> of RDF databases 
and addresses a number of bug fixes in both OWLIM and Sesame, together 
with some performance improvements over version 4.0.

This latest version is bundled with Sesame 2.4.2 
<http://www.openrdf.org/> which includes many fixes for SPARQL 1.1 Query 
support, especially those relating to aggregate functions and complex 
GROUP BY expressions. Some issues with property paths have also been 
dealt with.

OWLIM-SE and OWLIM-Enterprise have been updated with fixes relating to 
query evaluation logic and improvements in query performance. Some 
problems when using named graphs with the Jena 
<http://jena.sourceforge.net/> adapter have also been addressed.

Ontotext continue to develop OWLIM and upcoming releases will include 
full SPARQL 1.1 Update/Federation functionality, data-type indices, 
graph level security and many other features/enhancements.

Full documentation for all OWLIM editions is available online 

The OWLIM team.
