We are pleased to announce new releases of Jena and ARQ:

Jena: http://prdownloads.sourceforge.net/jena/jena-2.5.7.zip

ARQ: http://prdownloads.sourceforge.net/jena/arq-2.6.0.zip

The version of ARQ in the Jena download and version of Jena in the ARQ download
are sync'ed to these releases. You only need download one of them to get all
the jar files.

The difference is that the Jena download has the documentation and source for
Jena, and the ARQ download has the documentation and source for ARQ.

FileManager redirects.
o Fixed problem withLPTopGoalIterator which caused one extra level

==== ARQ 2.6.0
(changes since the version shipped with Jena 2.5.6)

+ Added .close() to Dataset and GraphStore for those implementations that
need to make changes permanent or release system resources.

+ Fix bug in SPARQL grammar (!) : expressions like "1+2*3" did not parse.
This is a fix to the grammar as published by the working group.
It does not invalidate or change any query that works - it makes some
illegal syntax work that should work.

+ Redesign of quad support.
AlgebraGeneratorQuad retired
Use Algebra.toQuadForm(Op) to turn an algebra expression into quads.

+ fn:string-join was misnamed - was actually renamed as fn:concat
And now takes arbitrary number of arguments

+ Bug fix: path parsing when "a" (for rdf:type)
is used in a property list (using ;)

+ Bug fix: LET expressions did not eliminate solutions when
assigned a new, different value.

+ Signal start/end of updates using the graph-level events mechanism.

+ Change to interface for query compilation : Algebra.compile and
Algebra.optimize

+ Property paths added. See documentation.
