New in Version 0.4.174

• Functions and classes are now contained in a MEDDLY namespace.

• Top-level functions named MEDDLY_function have been renamed as function.
  For example, MEDDLY_createDomain() can now be called as MEDDLY::createDomain(), or as createDomain() inside a using namespace MEDDLY block.

• There is a single, centralized error class. All methods that previously returned error
  now return void, and any errors are passed back to the user using throw. For example, the old code fragment

  domain::error e = dom->createVariablesBottomUp(vars, N); 
  if (e != domain::SUCCESS) { 
    fprintf(stderr, "Error: %s\n", domain::getErrorCodeName(e)); 
    exit(1); 
  } 
  

  now becomes

  try { 
    dom->createVariablesBottomUp(vars, N); 
  } 
  catch (MEDDLY::error e) { 
    fprintf(stderr, "Error: %s\n", e.getName()); 
    exit(1); 
  } 
  

• The library must be initialized before use. (Most operations will fail and throw an appropriate error, otherwise.) This can be done via

  MEDDLY::initialize(); 
  

  which uses default settings. To use different settings:

  MEDDLY::settings s; 
  // change members of s here; 
  // the constructor will fill everything with default values so 
  // it is only necessary to specify the non-default values. 
  MEDDLY::initialize(s); 
  

• compute_manager::setHashTablePolicy() has been removed, as this functionality is now provided using the appropriate settings during library initialization.

• Library memory may be released using

  MEDDLY::cleanup(); 
  

  Most operations will fail and throw an appropriate error after cleanup() is called. If desired, the library may be initialized again.
