                            RELEASE NOTES FOR HEASOFT 6.3.1
                                    July 27, 2007
    ******************************************************************************
    
    The HEASoft 6.3.1 release is primarily driven by the release of the
    Suzaku (version 6) and Swift (version 2.7.1) software, but also includes
    some minor configuration changes.
    
    As before, configuration-related changes thoughout the package means that
    users who already have HEASoft v6.x.x installed will need to completely
    replace their software installation; there is no clean way to simply
    overlay this new release or to update an existing installation.
    
    ******************************************************************************
                                    Configuration
    ******************************************************************************
    
    - ftools component:
    
      Fix optimization switch previously implemented: C optimization should be
      turned down (to -O, not off) any time gcc 4.0.1 is being used (currently
      on most Darwin OS), not just for Intel Mac (the previous implementation).
      This fixes a known bug in gcc 4.0.1 that breaks cfortran-generated code.
      Force Darwin g95 optimization to -O to fix xspec12 zwabs model problem.
    
    - Xspec 12 component:
    
      Force Darwin g95 optimization to -O to fix xspec12 zwabs model problem.
    
    *****************************************************************************
                                       XSPEC 11
    *****************************************************************************
    
    In the original release of HEAsoft 6.3, XSPEC v11 had a bug triggered by
    using the addcomp command to insert a component into a model.  This bug
    was fixed in the 6.3 release downloads on 13 July 2007 and is now included
    in the 6.3.1 release as well.

    The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.
