Meandre 1.4.5 was released today, May 19, 2009. This is (hopefully) the last and most stable release in the 1.4 series before we move onto big changes for the 1.5 series. Version 1.4.5 has a few new features and numerous bug fixes and usability improvements.

As usual, the Download page now points to this stable release:

Visible changes since 1.4.4:

* Workbench now supports flows written in ZigZag
* Workbench can output flows to the .mau format
* Bug fixes in the job submission API for flows that finish quickly
* Flow RDF representations can be converted to ZigZag
* Infrastructure web API and HTML interface added “Publish All” ability
* Bug fixes for multiple users running the same flow
* Stack trace is now printed for the failing Component when a Flow execution aborts unexpectedly

The Visual Understanding Environment (VUE) Team at Tufts University held a webinar on May 5, 2009 to highlight the project’s new features. This presentation included a prototype integration with SEASR. Check out the webinar here.

On May 11 and 12, 2009 Loretta Auvil, Bernie Acs, and Xavier LlorĂ  worked with a research group led by UIUC Professor Brant Houston. Others joining include David Donald, Jennifer LaFleur, and Jaimi Dowdell.

This was a follow-up workshop from our meeting in January. In the workshop the SEASR staff worked with the researchers to apply existing SEASR tools and to identify other needed tools. The workshop was a success in getting the Journalism group moving toward their goals and to identify specific analysis to target. Additionally, SEASR staff have identified needed changes in their components and flows that will result in adjustments and further development.
