Erlang 编程语言
Erlang是一个结构化，动态类型编程语言，内建并行计算支持。最初是由爱立信专门为通信应用设计的，比如控制交换机或者变换协议等，因此非常适 合于构建分布式，实时软并行计算系统。
Erlang/OTP是一个主要版本，更新了新功能，相当多的改进，以及一些不兼容。
更新日志：
compiler, stdlib:
New preprocessor macros ?FUNCTION_NAME, ?FUNCTION_ARITY
New preprocessor directives -error(Term) and -warning(Term) to cause a compilation error or warning, respectively.
gen_statem a new state machine behavior
mnesia_ext: plugin of external storage solutions to mnesia
crypto: uses EVP interface in OpenSSL resulting in generally better performance and support for HW acceleration
ssh: performance improvements, uses the new gen_statem behavior
ssl: enhanced error log messages
dialyzer: the support for maps is very much extended both the type specification syntax and the type analysis.
erts:
erlang:open_port(spawn, ...) 3-5 times faster
tracing, extensive improvements (scalability, speed, match specifications on send/receive, support for lttng, ...)
dirty schedulers improved
per process configurable handling of message_queue
fast loading of multiple modules
max_heap_size process flag
erts/kernel: Experimental support for Unix Domain Sockets Example: gen_udp:open(0, [{ifaddr,{local,"/tmp/socket"}}])
and much more ....
