125****************************************************************************
126
127Qt for Linux/X11
128----------------
129
130 - [QTBUG-15008] Fix broken prefix setting in configure when EPOCROOT shell
131   variable is set.
132
133Qt for Windows
134--------------
135
136 - QtQuick
137    * [QTBUG-16885] QDeclarativeEngine::addImportPath() did not work if the
138      drive letter is in lowercase.
139    * [QTBUG-17360] Make sure $QTDIR/plugins/qmldebugging/tcpserver.dll is
140      found in windows release builds.
141
142Qt for Mac OS X

144
145 - [QTBUG-13772] Returning form fullscreen mode causes assertion failure.
146 - [QTBUG-14023] Added missing plugins to debug-libs package.
147 - [QTBUG-14420] Switching from an application with undocked widgets hid the
148   application.
149 - [QTBUG-15638] Fixed incorrect QComboBox drop-down menu Z-ordering.
150 - [QTBUG-15666] Fixed crash when closing QFontDialog::getFont() dialog before
151   its event loop finished.
152 - [QTBUG-16279] Fixed deadlock in QSyntaxHighlighter::highlightBlock.
153
154Qt for Symbian
155--------------
156
157 - Multimedia
158    * [QTBUG-17040] Prevent menu and native title pane area popping up when
159      setting fullscreen mode off during video playback.
160 - Packaging changes
161    * [QTBUG-17399] Remove sqlite3 from Qt SIS for S60 3.2 and 5.0 to allow
162      Nokia Content Signing, which doesn't permit sis files to have other
163      sis files embedded inside.
164 - Paging changes
165    * [QT-3503] Remove PAGED keyword from all Qt-based binaries for
166      MMP-based build systems (abld, SBSv2 (a.k.a. Raptor)).
167      This changes the code paging field in the Symbian (E32Image) header
168      from "paged" to "default".  Thus it is left to the configuration
169      of the particular device whether paging is used for the binary or
170      not.  All devices that support code paging should have it turned
171      on (the value is stored in the HAL, so can be checked using eg.
172      fshell); data paging may or may not be turned on depending on the
173      device characteristics.  Leaving both code and data paging as
174      "default" means that any limitations in the device (eg. around
175      flash wear) can be controlled by that device by disabling the
176      appropriate types of paging rather than being forced by the binary
177      (which may be deployed to several different devices with different
178      characteristics).
179 - Phonon MMF backend
180   * [QTBUG-11436] Added a MediaObject property which allows the client to
181     specify which Internet Access Point should be used for streaming.
182 - QApplication
183   * [QTBUG-15915] Fix crash when creating more than one QApplication in single
184     test case.
185   * [QTBUG-16065] QApplication object with QApplication::GuiServer type caused
186     crash on Symbian devices.
187 - QDesktopWidget
188   * [QTBUG-16095] Resize event for QDesktopWidget was sent too early.
189 - QDialog
190   * [QTBUG-16277] Fix fullscreen/Maximized dialog misplacement in Symbian.
191   * [QTBUG-16110] QMessageBox softkeys were dimmed when application returned
192     to foreground.
193 - QEventDispatcherSymbian
194   * [QTBUG-16380] Fix leaking of RTimer handles.
195 - QFileDialog
196   * [QTBUG-16204] Fix using QFileDialog statics in Symbian.
197 - QFontDatabase

203 - qmake & mkspecs
204   * [QT-4193] Only add ICON for application projects in symbianpkgrules.pri
205   * [QTBUG-13159] Allow pkg_prerules and pkg_postrules to be targeted to separate
206     files.

208     modifier support for DEPLOYMENT items in Symbian.
209   * [QTBUG-14280] Implement support for DEPLOYMENT.display_name in Symbian.
210   * [QTBUG-13917] Localize .loc and .pkg content based on TRANSLATIONS.
211   * [QTBUG-15159] Use include(original mkspec) instead of copying of mkspec to
212     default.
213   * [QTBUG-15393] Resolve EPOCROOT in qt.conf using same logic as in .pro.
214   * [QTBUG-15501] Fix symbian-mmp.conf include path.

230   * [QTBUG-16753] Improved QMAKE_POST_LINK support in symbian-sbsv2.
231   * [QTBUG-16881] Fix QMAKE_POST_LINK for targets with special characters.
232   * [QTBUG-16888] No longer replace dash and dot in TARGET with underscore.
233   * [QTBUG-17187] Ensure that package generated against Symbian^3 SDK has no
234     Symbian^1 platforms as dependencies.
235   * Fix partial upgrade package UID for libinfixed Qt.
236   * Cleaned up sis_targets.prf.
237 - QNetworkProxyFactory

255   * [QTBUG-16685] Fix crash in JavaScript stack allocator.
256 - QWidget
257   * [QTBUG-16578] In cases where the widget was created from the event loop
258     instead of main(), the middle three softkeys would not get the right
259     visibility and would leave a "hole" in the application where one could
260     see what was beneath it.
261   * [QT-4416, QTBUG-17288] On devices which lack support for transparency
262     in EGL surfaces, setting Qt::WA_TranslucentBackground on a widget
263     whose windowType() is Qt::Window causes that widget to be rendered
