========================
WST 1.3 includes the following changes:
 - New capabilities to solve flushing optimization for large problems, 
   including parallelization and stop time criteria
 - Compatibility with Pyomo 4.0
 
 - CMake build harness
 
 - Additional tests
 
 - Bug fixes

Changelog WST 1.2 (2014/12/22)
========================
WST 1.2 expands the capabilities of WST with the following features:
 - Added the EPANET_BTX and CSA libraries for source inversion
 - Expanded booster_mip to include the PD metric
 - Added the network local search solver to booster_msx
 - Efficiency improvements to the flushing component (bundling
   simulation scenarios) 
 - Expanded support for result visualization
 - A prototype build harness based on CMake
 - Numerous bug fixes

Changelog WST 1.1.1 (2014/03/31)
========================
WST 1.1.1 is a patch release that bundles an updated version of PyEPANET
that corrects issues some users were seeing with the PyEPANET interface
to the EPANET DLL on Windows platforms.

Changelog WST 1.1 (2014/02/06)
========================
WST 1.1 is the first external release for WST.  WST builds upon the simulation 
and optimization framework of TEVA-SPOT and adds several new features. These 
features were all developed to model possible response action plans once 
contamination has been detected in the system.  WST 1.1 includes the following 
components:
 - Contaminant transport
 - Impact assessment
 - Sensor placement
 - Hydrant flushing locations
 - Booster placement
 - Source inversion
 - Grab sampling

The WST User Manual documents the use of each component in WST.

Changelog WST 1.0 (2012/4/19)
========================
Preliminary release of WST intended as a test bed for the development team.
The contaminant transport simulation, impact assessment and sensor placement 
optimization tools were all developed as part of the TEVA-SPOT Toolkit.  
All functionality in TEVA-SPOT has been replicated in WST using new, user 
friendly YAML format configuration files. Future development for functionality 
in TEVA-SPOT will occur in the WST software repository.
