We are pleased to announce the official release of TORQUE 2.5.0. 
Improved job arrays and Cygwin support are the main new features for 
this release.

_Please be advised that the job arrays in 2.5.0 are not backward 
compatible with TORQUE 2.4.x or 2.3.x. Anyone upgrading to 2.5.0 that is 
currently using job arrays needs to be sure to drain all job arrays from 
their system before upgrading._

New features of job arrays include slot limits which allows users and 
administrators to control the number of simultaneous running jobs from a 
job array submission. Job dependencies can also be based on entire 
arrays as well as individual jobs. Job arrays are now suported in the 
commands qalter, qdel, qhold, qrls in addition to the qsub command.

With special thanks to Igor Ilyenko, Yauheni Charniauski and Vikentsi 
Lapa TORQUE is now able to run under Cygwin. This new feature has been 
created by the community and will be supported by the community. 
Adaptive Computing will not officially support this feature at this time.

The 'procs' resource option is now fully supported. Previous versions of 
TORQUE only passed this resource through to schedulers who then 
interpreted the directive. The 'procs' features allows users to select a 
number of processors for a job without the need to specify the nodes on 
which the processors should come.

There is an improved wildcard support for queue and server parameters. 
Previous versions of TORQUE could only match the '*' wildcard to the end 
of a string. TORQUE will now support the '*' anywhere in a string. 
TORQUE also added the ability to create ranges on names such as 
user at node[1-5] to specify on a single line that node1 through node5 
qualify for any queue or server parameter.

Thanks to everyone who helped get this build ready for release.
