Some highlights of the release are:
- ssl: Add possibility to downgrade an SSL/TLS connection to a tcp
connection, and give back the socket control to a user process.
- ssh: The following new key exchange algorithms are implemented:
'ecdh-sha2-nistp256', 'ecdh-sha2-nistp384', 'ecdh-sha2-nistp521',
'diffie-hellman-group14-sha1', 'diffie-hellman-group-exchange-sha1'
and 'diffie-hellman-group-exchange-sha256'. This raises the
security level considerably.
- kernel,stdlib,sasl: A mechanism for limiting the amount of text
that the built-in error logger events will produce has been
introduced. It is useful for limiting both the size of log files
and the CPU time used to produce them.

erlang 16.1.3.1 (R16B03-1)
================================
Highlights:
- The ODBC application was missing in the prebuilt Windows installers
- 3 corrections in the SSL application:
- Add missing validation of the server_name_indication option and test
for its explicit use.

suggested by the client, if possible.
- The server did not indicate support for secure renegotiation during
TLS extension handling.
- In the syntax tools application a bug was introduced which broke
reverting of local funs. This is now corrected (thanks to Anthony Ramine)
- wx - Solved a problem which caused the debugger to crash when closing
a window. Fixed static linking on Mac.
- xmerl - Fixed a problem in the SAX-parser when the header of
the next document was appearing in the buffer when using
the xmerl_sax_parser:stream/2 function.

erlang-16.1.3 (R16B03)
================================
Highlights:
- A new memory allocation feature called "super carrier" has been introduced.
It can for example be used for pre-allocation of all memory that the
runtime system should be able to use. It is enabled by passing the +MMscs
(size in MB) command line argument. For more information see
the documentation of the +MMsco, +MMscrfsd, +MMscrpm, +MMscs, +MMusac, and,
+Mlpm command line arguments in the erts_alloc(3) documentation.
- The ldap client eldap now supports the start_tls operation. This upgrades
an existing tcp connection to encryption using tls,
see eldap:start_tls/2 and /3.
- The ftp client (inets application) now supports ftp over tls (ftps).

been updated in more than two years.)

Ok by wiz.
