    Time Event
    1:52p
    Kernel prepatch 5.4-rc3
    The 5.4-rc3 kernel prepatch is out for
    testing. "Things continue to look fairly normal, with rc3 being
    larger than rc2, as people are starting to find more regressions, but 5.4
    so far remains on the smaller side of recent releases.    "

    Security updates for Monday
    Security updates have been issued by Arch Linux (chromium, sdl, and unbound), Debian (clamav, libdatetime-timezone-perl, openssl, tcpdump, and tzdata), Fedora (cutter-re, jackson-annotations, jackson-bom, jackson-core, jackson-databind, jackson-parent, libapreq2, ming, opendmarc, radare2, and thunderbird), openSUSE (chromium), Oracle (kernel), and SUSE (axis, jakarta-commons-fileupload, kernel, sles12sp3-docker-image, sles12sp4-image, system-user-root, and webkit2gtk3).

    [$] Finding race conditions with KCSAN
    Race conditions can be some of the trickiest bugs to find. The resulting
    problems can be subtle, and reproducing the problem in order to track it
    down can be difficult or impossible; often code inserted to narrow down a
    race condition will cause it to stop manifesting entirely. A tool that can
    find race conditions automatically would thus be a valuable thing for the
    kernel community to have. In late September, Marco Elver announced
    a tool called KCSAN     (the Kernel Concurrency Sanitizer) that does
    exactly that — and which has already found a number of real problems.
    7:11p
    PyPy 7.2 released
    Version
    7.2     of PyPy, an implementation of the Python language, is out. With
    this release, Python 3.6 support is deemed ready: "This release
    removes the 'beta' tag from PyPy3.6. While there may still be some small
    corner-case incompatibilities (around the exact error messages in
    exceptions and the handling of faulty codec errorhandlers) we are happy
    with the quality of the 3.6 series and are looking forward to working on a
    Python 3.7 interpreter.    "
    10:15p
    Python 3.8.0 released
    Version
    3.8.0     of the Python language has been released. New features include
    the controversial assignment expressions,
    positional-only arguments,
    the Vectorcall
    mechanism    , and more; see the what's new in Python
    3.8     document for more information.
