    You are receiving this message because you are on the checkpoint_at_lbl_dot_gov
    list, or have e-mailed us in the past with questions about the
    development status of Berkeley Lab Checkpoint/Restart (BLCR) for Linux.
    I am pleased to announce that version 0.4.2 is now available on our
    website at
    This release marks as "stable", the experimental 2.6 kernel support
    first available in 0.4.0 and the Opteron/EM64T support available in the
    0.4.1-beta series.
    There are also numerous bug fixes in this release.
    After packaging of BLCR 0.4.2, we were made aware of a significant
    kernel change in the 2.6.12 and later kernels.   Therefore release 0.4.2
    works only with kernels upto 2.6.11.  As soon as possible, we'll post a
    0.4.3 release or a patch (depending on the size of the changes) to allow
    BLCR to work with 2.6.12 and newer kernels.
    Opteron/EM64T users should be aware of two limitations:
    + There is no support for 2.4 kernels with the x84_64 architecture (and
    no plans for it)
    + There is currently no support for 32-bit apps on 64-bit kernels, but
    the support is in early testing and may be avaialble in 0.4.3.
