OTP-12837 Application(s): kernel<br>

Add {line_delim, byte()} option to inet:setopts/2 and<br>
decode_packet/3<br>
<br>
In the documentation it appears to be {line_delimiter, byte()}.<br>
<br>
In the documentation it is listed in the text below the function, but not in the types (true for both decode_packet and inet:setopts/gen_tcp:option).<br>
<br>
Finally the choice of a single byte is curious. For example in HTTP the line delimiter is \r\n.<br>

(characteristics) improvements, as well as a few incompatibilities.<br>
<br>
Some highlights of the release are:<br>
<br>
* *compiler, stdlib*:<br>
o New preprocessor macros *?FUNCTION_NAME, ?FUNCTION_ARITY*<br>
o New preprocessor directives -error(Term) and -warning(Term) to<br>
cause a compilation error or warning, respectively.<br>
<br>
* *gen_statem* a new state machine behavior<br>
* *mnesia_ext*: plugin of external storage solutions to mnesia<br>
* *crypto*: uses EVP interface in OpenSSL resulting in generally<br>
better performance and support for HW acceleration<br>
* *ssh*: performance improvements, uses the new gen_statem behavior<br>
* *ssl*: enhanced error log messages<br>
* *dialyzer*: the support for maps is very much extended both the type<br>
specification syntax and the type analysis.<br>
* *erts*:<br>
o erlang:open_port(spawn, ...) 3-5 times faster<br>
o tracing, extensive improvements (scalability, speed, match<br>
specifications on send/receive, support for lttng, ...)<br>
o dirty schedulers improved<br>
o per process configurable handling of message_queue<br>
o fast loading of multiple modules<br>
o max_heap_size process flag<br>
* *erts/kernel:*<br>
o |Experimental support for Unix Domain Sockets<br>
||Example: ||gen_udp:open(0, [{ifaddr,{local,"/tmp/socket"}}])|||<br>
* and much more ....<br>
