    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:
    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.
    You are receiving this either because you are on the checkpoint_at_lbl_dot_gov
    list, because you've recently sent email to the list (or me directly)
    asking about BLCR status, or because our Bugzilla shows your interests
    in a bug fixed in this beta.

    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.
