Subject: * Added support for yum libraries (if available and configured). 
 This   can dramatically reduce memory usage, and fixed several bugs:   *
 #1014 (Package plugin can't resolve dependencies for rpms with     Require:
 tags for full paths that aren't Provided explicitly)   * #991 (Dependency
 Resolution difference between Package and yum)   * #996 (Packages high memory
 usage) * Added support for Yum package groups when using yum libraries  
 (#1039) * Fixed #911 (bcfg2 output for wrong package version with Packages is
   misleading) * YUMng turns down the Yum debug level itself depending on the 
  debug/verbosity level requested by bcfg2 so you don't have to reduce   the
 Yum debug level on a global basis * Added support for Pulp repositories,
 including registering Pulp   consumers and binding to repositories * Added
 ability to disable magic OS groups
