Dear all,

I am pleased to announce the release of CMPL 1.8.0 .

New features and change log
pyCMPL and CMPLServer	
		pyCMPL is the CMPL API  for Python and an interactive shell. 
		The main idea of this API is to define sets and parameters within the user
		application, to start and control the solving process and to read the solution(s) 
		into the application if the problem is feasible. All variables, objective 
		functions and constraints are defined in CMPL. 
		These functionalities can be used with a local CMPL installation or a CMPLServer.

		CMPLServer is an XML-RPC-based web service for distributed optimization.
		It is reasonable to solve large models remotely on the CMPLServer that is 
		installed on a high performance system. pyCMPL provides a client API for 
		CMPLServer. CMPL provides three XML-based file formats for the communication 
		between a CMPLServer and its clients. (CmplInstance, CmplSolutions, CmplMessages)

		pyCMPL and CMPLServer are an open source projects licensed under LGPLv3 and  
		available for most of the relevant operating systems (Windows, OS X and Linux)

New CMPL command line arguments
		-interRelaxation - All integer variables are changed to continuous variables
		-alias  - uses an alias name for the cmpl model
		-solution [filename] - optimization results in CmplSolutions XML format 

Changed CMPL command line argument
		-gn - turns matrix reductions on (default off) 

New display options 
		-ignoreVars - Ignores all variables in the solution reports
		-ignorevars - Ignores all constraints in the solution reports

MPrL XML format is changed into the CmplMessages XML format (CMPL does not longer support MPrL)
New solution XML format CmplSolutions 

Bug fixing
		A bug for readcsv() that only appeared under Windows is fixed.

The Binaries are available at www.coliop.org/download.html.
