+ The internal handling of SSH options is re-written.</p>
+ <p>
+ Previously there were no checks if a client option was
+ given to a daemon or vice versa. This is corrected now.
+ If your code has e.g. a client-only option in a call to
+ start a daemon, the call will fail.</p>

+ <p>
+ Modernization of key exchange algorithms. See
+ draft-ietf-curdle-ssh-kex-sha2 for a discussion.</p>
+ <p>
+ Removed an outdated weak algorithm and added stronger
+ replacements to keep interoperability with other modern
+ ssh clients and servers. The default ordering of the
+ algorithms is also adjusted.</p>
+ <p>
+ Retired: The nowadays unsecure key-exchange
+ <c>diffie-hellman-group1-sha1</c> is not enabled by
+ default, but can be enabled with the option
+ <c>preferred-algorithms</c>.</p>
+ <p>
+ Added: The new stronger key-exchange
+ <c>diffie-hellman-group16-sha512</c>,
+ <c>diffie-hellman-group18-sha512</c> and
+ <c>diffie-hellman-group14-sha256</c> are added and
+ enabled by default.</p>
+ <p>
+ The questionable [RFC 6194] sha1-based algorithms
+ <c>diffie-hellman-group-exchange-sha1</c> and
+ <c>diffie-hellman-group14-sha1</c> are however still kept
+ enabled by default for compatibility with ancient clients
+ and servers that lack modern key-exchange alternatives.
+ When the draft-ietf-curdle-ssh-kex-sha2 becomes an rfc,
+ those sha1-based algorithms and
+ <c>diffie-hellman-group1-sha1</c> will be deprecated by
+ IETF. They might then be removed from the default list in
+ Erlang/OTP.</p>

+ <p>
+ The Extension Negotiation Mechanism and the extension
+ <c>server-sig-algs</c> in
+ draft-ietf-curdle-ssh-ext-info-05 are implemented.</p>
+ <p>
+ The related draft-ietf-curdle-rsa-sha2-05 is implemented
+ and introduces the signature algorithms
+ <c>rsa-sha2-256</c> and <c>rsa-sha2-512</c>.</p>

+ The 'timeout' and 'connect_timeout' handling in
+ ssh_sftp:start_channel documentation is clarified.</p>

+ <p>
+ The functions <c>ssh:connect</c>, <c>ssh:shell</c> and
+ <c>ssh:start_channel</c> now accept an IP-tuple as Host
+ destination argument.</p>

+ Own Id: OTP-14243</p>
+ </item>
+ <item>
+ <p>
+ The function <c>ssh:daemon_info/1</c> now returns Host
+ and Profile as well as the Port info in the property
+ list.</p>
+ <p>
+ Own Id: OTP-14259</p>
+ </item>
+ <item>
+ <p>
+ Removed the option <c>public_key_alg</c> which was
+ deprecated in 18.2. Use <c>pref_public_key_algs</c>
+ instead.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>

+ <p>
+ The SSH application is refactored regarding daemon
+ starting. The resolution of contradicting <c>Host</c>
+ argument and <c>ip</c> option were not described. There
+ were also strange corner cases when the <c>'any'</c>
+ value was used in <c>Host</c> argument or <c>ip</c>
+ option. This is (hopefully) resolved now, but it may
+ cause incompatibilities for code using both <c>Host</c>
+ and the <c>ip</c> option. The value 'loopback' has been
+ added for a correct way of naming those addresses.</p>

+ The supervisor code is refactored. The naming of
+ listening IP-Port-Profile triples are slightly changed to
+ improve consistency in strange corner cases as resolved
+ by OTP-14264</p>
