OTP 24.3 is released

OTP 24.3

Erlang/OTP 24.3 is the third and final maintenance patch package for OTP 24, with mostly bug fixes as well as a few improvements.

Below are some highlights of the release:


  • crypto: The crypto app in OTP can now be compiled, linked and
    used with the new OpenSSL 3.0 cryptolib. It has not yet been extensively tested,
    so only recommended for experiments and alpha testing in this release.
    There are not yet any guaranties that it works, not even together with other
    OTP applications like for example SSL and SSH, although
    there are no known errors.
  • erts, kernel: Support for using socket:sockaddr_in() and
    socket:sockaddr_in6() when using gen_sctp, gen_tcp and
    gen_udp, will make it possible to use Link Local
    IPv6 addresses.
  • erts, kernel: By default global does not take any actions to restore
    a fully connected network when connections are lost due
    to network issues. This is problematic for all
    applications expecting a fully connected network to be
    provided, such as for example mnesia, but also for
    global itself. A network of overlapping partitions
    might cause the internal state of global to become
    inconsistent. Such an inconsistency can remain even
    after such partitions have been brought together to
    form a fully connected network again. The effect on
    other applications that expects that a fully connected
    network is maintained may vary, but they might
    misbehave in very subtle hard to detect ways during
    such a partitioning. In order to prevent such issues, we have introduced a
    prevent overlapping partitions fix which can be enabled
    using the prevent_overlapping_partitions kernel(6)
    parameter. As of OTP 25 this fix will become enabled by default
