====== Release Notes 5.4 ======

GridWay 5.4, which is also shipped with GT4.2.0, is a new stable version with increased functionality, including support to access the NorduGrid infrastructure, new bindings for DRMAA and support for DAGMAN workflows.

Release Date: July 9th, 2008

===== Integration with major Grid Infrastructures =====

Following the trend from previous releases, GridWay is capable of integrate with another major infrastructure: NorduGrid. Drivers for Execution and Transfer are included in this release.

===== New DRMAA bindings for scripting languages =====

Previous GridWay releases come with support for C and Java bindings implementing the DRMAA standard. Scripting languages are interesting from the point of view of rapid application prototyping among others. From dsa-research.org we believe this to be an interesting aspect, and that is why GridWay includes bindings to access the DRMAA standard from scripting languages such as Perl, Ruby and Python.

===== Support for DAGMAN workflows =====

There is an increasing interest from the scientific community to be able to run complex workflows on a Grid environment. An almost //de-facto// standard to represent DAG workflows is Condor DAGMAN. In this development release GridWay includes a new workflow launcher (gwdag) that handles this kind of workflows.
