- Changes for 22.1.4 * http://erlang.org/download/OTP-22.1.4.README * compiler: Fixed a bug where the compiler could generate incorrect code for a 'receive' statement inside a 'try'. * crypto: FIxed a bug if the erlang emulator was linked with a very old cryptolib version (1.0.1 or earlier). The bug now fixed could have triggered a core dump if an unknown cipher name was used in crypto functions. * erts: Erlang/OTP can now be built on macOS Catalina (10.15).

# 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 ```
