- Update to 21.3: - Changes for 21.3: * http://erlang.org/download/OTP-21.2.7.README * Erlang/OTP 21.3 is the third service release for the 21st major release with improvements, as well as a few features * Highlights * Kernel: The standard logger handler, logger_std_h, now has a new internal feature for log rotation. For full information see the documentation. * SSL:The Reason part of the error return from the functions connect and handshake has a better and documented format. This is a potential incompatibility. See the documentation. Refactoring of state handling has improved the TLS application data throughput and reduced CPU overhead Code optimizations has reduced CPU load for encryption/decryption, especially for Erlang's distribution protocol over TLS Now supports active N * Erl_interface: Support for plugin of a user supplied socket implementation has been added. * OTP:The HTML reference documentation now shows the OTP version where modules and functions were first introduced. Versions of OTP older than R13B04 is not shown in the reference documentation * For a full list of details see: http://erlang.org/download/otp_src_21.3.readme - Update to 21.2.7: - Changes for 21.2.7: * http://erlang.org/download/OTP-21.2.7.README * erts, otp: Fixes of install/release phase in build system. -- The source tree was modified when installing/releasing and/or applying a patch. -- Some files were installed with wrong access rights. -- If applying a patch (using otp_patch_apply) as another user (except root) than the user that built the source, the documentation was not properly updated. * erts, kernel: Setting the recbuf size of an inet socket the buffer is also automatically increased. Fix a bug where the auto adjustment of inet buffer size would be triggered even if an explicit inet buffer size had already been set. * erts: Reading from UDP using active true or active N mode has been optimized when more packets than specified by read_packets are available on the socket. * erts, kernel: Setting the recbuf size of an inet socket the buffer is also automatically increased. Fix a bug where the auto adjustment of inet buffer size would be triggered even if an explicit inet buffer size had already been set.

# Erlang in openSUSE ## Erlang Port-mapper Daemon and systemd Erlang Port-mapper Daemon in openSUSE uses systemd socket-activation. In order to fulfill security considerations, EPMd listens on loop-back interface by default. This is enough to run rabbitmq-server, ejabberd and user-started beam processes. For clustering, please, use ```/etc/systemd/system/epmd.socket.d/``` to configure interfaces to listen on. See man systemd.unit(5) for details. ### Upgrading from sysvinit ```/etc/sysconfig/erlang``` has no effect now, to configure EPMd use systemd capabilities instead. ### Example 1: change port Create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=127.0.0.1:4444 ``` The first line is to discard vendor configuration. The second line will change the port number to listen on to 4444. ### Example 2: enable external interface To enable accepting external connections to EPMd, create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=0.0.0.0:4369 ```
