+Qt 5.4.1 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.4.0.
+
+For more details, refer to the online documentation included in this
+distribution. The documentation is also available online:
+
+  http://qt-project.org/doc/
+
+The Qt version 5.4 series is binary compatible with the 5.3.x series.
+Applications compiled for 5.3 will continue to run with 5.4.

+*                          Library                                         *

+
+ - Improved the Terminal and Enumerator examples:
+   * In the Terminal example, users can now specify a custom serial port name.
+   * The Terminal example no longer attempts to close a serial port that is
+     already closed. It allows to suppress an additional message box with the
+     NotOpenError error.
+   * Added a scroll area to the Enumerator example.
+   * Q_NULLPTR is now used where it is possible.
+
+ - QSerialPortInfo:
+   * [QTBUG-41262] Now the QSerialPortInfo::isNull() returns true when it
+     is empty.
+   * Improved the algorithm of serial ports enumeration for Unix-like systems.
+     Devices are no longer looked for in /dev/ if udev or sysfs return nothing.
+   * Improved the sysfs backend's algorithm for enumeration of serial ports
+     on Linux.
+   * [QTBUG-32024] Fixed detection of valid serial8250 serial ports on Linux.
+   * Added detection of Bluetooth SPP (rfcomm) serial port with SysFs backend.
+
+ - QSerialPort:
+   * [QTBUG-38639] Allowed using custom (non standard) serial ports paths
+     that can be used as symlinks or do not start with '/dev', and so on.
+   * Fixed leak of event handles on Windows.
+   * Added handling for EINVAL, ENOIOCTLCMD, ENOTTY and EPERM errors on
+     Unix-like systems.
+   * The serial port is now marked as opened only if all settings were applied
+     internally. This enables suppressing the NotOpenError when the close()
+     method is called from a slot that is connected to the SerialPortError
+     signal.
+   * Fixed setting up an error on Unix-like systems, when the setBaudRate()
+     method fails.
+   * The serial port no longer queries the state of RTS and DTR lines when
+     opening. This enables suppressing the UnsupportedOperationError error when
+     a serial port does not support this feature (for example, when using
+     socat).
+   * [QTBUG-43484] Fixed stalling of reading when multiple open and
+     close calls are used in a row.
+   * Fixed stalling of reading on Windows when the clear() method is used.
+   * Fixed stalling of reading on Windows when the buffer size is limited.
