====== Release Notes 5.5 ======

GridWay 5.5 is the new development version of the fifth series of the metascheduler, completely backwards-compatible with version 5.4. Extra features and intensive bug fixing have been worked out.

Release date: October 19th, 2009.

===== LDAP Information MAD =====
Regarding the Information Manager (IM) a new Middleware Access Driver (MAD) has been developed for querying a Lightweight Directory Access Protocol (LDAP) server for information about the grid resources available.

===== XML support =====

==== Output of cli ====
Now the commands ''gwhost'', ''gwps'', ''gwuser'', ''gwhistory'' and ''gwacct'' accept a ''-x'' flag formatting all the information according to XML standards.

==== XML schema ====
A new [[http://dev.gridway.org/attachments/download/11/gridway.xsd |validation schema]] has been added to the distribution in order to validate the output of the command line interface. It is located under the ''xml_schema/'' folder.

===== Improved configuration script =====
The testing performed at the configuration stage before installation exits if the perl and ruby library requirements are asked for but not satisfied. They correspond to the ''<nowiki>--enable-ldap</nowiki>'' and ''<nowiki>--enable-drmaa-ruby</nowiki>'' options of ''./configure''.

===== On-line documentation =====
To avoid the duplication effort and improve the browsing experience through the different documentation sources, we have migrated all the documents to our [[:documentation|on-line section]]. You won't find anymore a ''doc/'' folder.
