<br>
This is the first of two planned release candidates before the OTP 21<br>
release. The intention whit this release is that you as users try it<br>
and give us feedback if something does not work as expected. Could be a<br>
bug,an unexpected incompatibility, a significant change of<br>
characteristics in a negative direction, etc. <br>
<br>
Erlang/OTP 21 is a new major release with new features, improvements as<br>
well as incompatibilities.<br>
<br>
Potential Incompatibilities<br>
<br>
* All Corba applications are now moved from the OTP repository<br>
* A new Corba repository will be created <a href="https://github.com/erlang" rel="noreferrer" target="_blank">https://github.com/erlang</a><br>
* New applications ftp and tftp, moved from inets<br>
* ssl no longer supports 3_DES cipher suites or RSA-key exchange<br>
cipher suites by default<br>
* erlang:monitor on a primitive node (erl_interface, jinterface, etc)<br>
will no longer fail with badarg exception. Instead a monitor will be<br>
created, but it will only supervise the connection to the node.<br>
<br>
Highlights<br>
<br>
Erts:<br>
<br>
* Enhanced IO scalability<br>
* Support for usage of distribution controller processes for<br>
alternative transports, routing etc<br>
* compact instructions on 64bit systems for code below 4GB 20% less<br>
memory for loaded code<br>
* Rewrite of the efile-driver with NIFs and "Dirty schedulers"<br>
resulting in faster file operations<br>
* non-smp VM removed<br>
* link and monitor optimized for scalability<br>
* os:getenv/putenv now work on thread-safe emulation. No longer in<br>
sync with libc getenv(3). Manual synchronization will be needed.<br>
<br>
Compiler:<br>
* Misc compiler optimizations including contributions from the<br>
Elixir team resulting in 10% improvements in benchmarks<br>
* "Tuple calls" have been removed from the run-time system.<br>
* Code such as f({ok, Val}) -> {ok, Val} is now automatically<br>
rewritten to f({ok, Val} = Tuple) -> Tuple. this reduces code<br>
size, execution time, and removed GC pressure.<br>
* More information in stacktrace from a number of operators<br>
* erlang:get_stacktrace/0 deprecated to be replaced with try ...<br>
catch C:R:Stacktrace -> ...<br>
* Creation of small maps with literal keys optimized.<br>
<br>
Security:<br>
* DTLS support in SSL<br>
* Enhanced support for distribution over TLS<br>
* "unsecure" ciphers removed from defaults in SSL and SSH.<br>
* A new option value defined to facilitate implementing exec<br>
servers. Old option kept for compatibility, but now gives errors<br>
on stderror.<br>
<br>
Standard libraries:<br>
* New API for logging, logger<br>
* New uri_string module for parsing URIs according to "The<br>
standard"<br>
* New function lists:search(list,fun/1) -> {ok, Value} | false<br>
* Changed default behaviour of .erlang loading. escript, erlc,<br>
dialyzer and typer no longer load an .erlang at all.<br>
