    I am pleased to announce the release of BLCR 0.7.1.
    
    The 0.7.1 release is now available from the BLCR Downloads page:
    http://ftg.lbl.gov/CheckpointRestart/CheckpointDownloads.shtml
    
    Relative to 0.7.0, this release fixes some bugs and adds support for the 
    2.6.26-rc7 kernel (with the hope it will support the full 2.6.26 kernel when 
    released).  A more detailed list of changes appears below in the form of an 
    excerpt from the NEWS file.

    NEWS:
    
    0.7.1
    --------
    June 25, 2008
    Bug fix and expanded-support release
      - Fix (part of) bug 2232, allowing nested use of cr_run.
      - Fix bug 2251, allowing use of HUGETLB_MORECORE=y with libhugetlbfs.
      - Fix bug 2295 (restart failure w/ heap > 4GB).
      - Fix sporadic EPERM failures when checkpointing encounters a zombie proc.
      - Add support for 2.6.26-rc7 kernel.
        While we don't officially support -rc<N> kernels, it is hoped that
        these changes will be sufficient to support the final 2.6.26.
      - Add cr_hold_ctrl(), allowing control over the thread hold behavior.
        This is required to restore the 0.6.X behavior for at least one
        application that would deadlock with the 0.7.X default behavior.
