Change Details

[Release notes](http://www.erlang.org/news/123)

- Enhanced IO scalability - compact instructions on 64bit systems for code below 4GB 20% less memory for loaded code - Rewrite of the efile-driver with NIFs and "Dirty schedulers" resulting in faster file operations - non-smp VM removed - link and monitor optimized for scalability - os:getenv/putenv now work on thread-safe emulation. No longer in sync with libc getenv(3). Manual synchronization will be needed. - Misc compiler optimizations including contributions from the Elixir team resulting in 10% improvements in benchmarks - "Tuple calls" have been removed from the run-time system. - More information in stacktrace from a number of operators - erlang:get_stacktrace/0 deprecated to be replaced with try ... catch C:R:Stacktrace -> ... - Creation of small maps with literal keys optimized. - A new predifined macro `OTP_RELEASE` and preprocessor directives `-if` and `-elif` - DTLS is now supported in the SSL application - Enhanced support for distribution over TLS - "unsecure" ciphers removed from defaults in SSL and SSH. - A new option value defined to facilitate implementing exec servers. Old option kept for compatibility, but now gives errors on stderror. - New API for logging, logger - New uri_string module for parsing URIs according to "The standard" - New function lists:search(list,fun/1) -> {ok, Value} | false - Changed default behaviour of .erlang loading. escript, erlc, dialyzer and typer no longer load an .erlang at all.
