Potentially incompatible changes: * ssh(1), sshd(8): the removal of "ssh-rsa" from the accepted CASignatureAlgorithms list. * ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1 from the default key exchange proposal for both the client and server. * ssh-keygen(1): the command-line options related to the generation and screening of safe prime numbers used by the diffie-hellman-group-exchange-* key exchange algorithms have changed. Most options have been folded under the -O flag. * sshd(8): the sshd listener process title visible to ps(1) has changed to include information about the number of connections that are currently attempting authentication and the limits configured by MaxStartups. x/mesa-19.3.4-x86_64-2.txz: Rebuilt.

+Subject: [PATCH] QtDBus: clean up signal hooks and object tree in
+ closeConnection
+
+If a QObject is added or passed as receiver to QDBusConnection::connect()
+and it is managed by Q_GLOBAL_STATIC or similar mechanism, it is
+possible that when that its destructor is called after the dbus daemon
+thread ends. In that case, QObject::destroyed connected via
+Qt::BlockingQueuedConnection to QDBusConnectionPrivate will cause dead
+lock since the thread is no longer processing events.
+
+Task-number: QTBUG-51648
+Change-Id: I1a1810a6d6d0234af0269d5f3fc1f54101bf1547
