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.
