1Qt 5.5 introduces many new features and improvements as well as bugfixes 2over the 5.4.x series. For more details, refer to the online documentation 3included in this distribution. The documentation is also available online: 4 5 http://doc.qt.io/qt-5.5 6 7The Qt version 5.5 series is binary compatible with the 5.4.x series. 8Applications compiled for 5.4 will continue to run with 5.5. 9 10Some of the changes listed in this file include issue tracking numbers 11corresponding to tasks in the Qt Bug Tracker: 12 13 http://bugreports.qt.io/ 14 15Each of these identifiers can be entered in the bug tracker to obtain more 16information about a particular change. 17 18**************************************************************************** 19* Deprecation Notice * 20**************************************************************************** 21 22 - Support for the following platforms or toolchains is deprecated in Qt 23 5.5 and will be removed as of Qt 5.6: 24 * Apple OS X builds using GNU libstdc++ 25 * BlackBerry 10 26 * QNX 6.5 27 28 The following platforms or toolchains are deprecated and will be 29 removed as of Qt 5.7: 30 * Apple OS X 10.7 (Lion) 31 * GNU Compiler Collection (GCC) versions 4.6 and earlier 32 * Microsoft Visual Studio compiler versions 2008 and 2010 33 * Microsoft Windows XP, Windows Vista 34 * Microsoft Windows Embedded Compact 7 35 36 Deprecated platforms and toolchains continue to work until removed. 37 38 - The QtWebKit and QtQuick1 modules and support for the QML 1 language 39 are deprecated and Qt 5.5 will be the last release to include 40 them. Starting with Qt 5.6, the source code for those modules will 41 not be included in Qt's packaging. Compiling the 5.5 release of 42 QtWebKit modules along with Qt 5.6 or future versions should 43 work. QtQuick1 is not guaranteed to work in future versions after 44 Qt 5.6. 45 46 - The QtScript module is deprecated and will be removed from Qt's 47 packaging starting with version 5.7. The 5.5 and 5.6 releases of 48 QtScript should continue to work along with Qt 5.7 and future 49 versions. 50 51 - [QTBUG-25121] The usage of the QStyleOptionProgressBar::orientation 52 member has been deprecated. 53 54 - QLibraryInfo::buildDate() was deprecated and will return a constant 55 date now. 56 57**************************************************************************** 58* Future Direction Notice * 59**************************************************************************** 60 61 - In Qt 6, QCoreApplication::notify() will not be called for events being 62 delivered to objects outside the main thread. The reason for that is 63 that the main application object may begin destruction while those 64 threads are still delivering events, which is undefined behavior. 65 Applications that currently override notify() and use that function 66 outside the main thread are advised to find other solutions in the mean 67 time. 68 69 - Qt 5.7 will begin requiring certain C++11 features in order to 70 compile. The minimum compiler versions for that release will be: 71 * Clang 3.2 (included in XCode 5.0) 72 * GCC 4.7 73 * Intel C++ Composer XE 2013 SP1 (compiler version 14.0) 74 * Microsoft Visual Studio 2012 (compiler version 17.0) 75 76**************************************************************************** 77* Important Behavior Changes * 78**************************************************************************** 79 80 - Q_ASSERT will now expand the condition even in release mode when asserts 81 are disabled, albeit in an unreachable code path. This solves compiler 82 warnings about variables and functions that were unused in release mode 83 because they were only used in assertions. Unfortunately, codebases that 84 hid those functions and variables via #ifndef will need to remove the 85 conditionals to compile with Qt 5.5. 86 - QDBusConnection::sender() (deprecated since Qt 4.3) has changed to 87 always return an invalid QDBusConnection. To know what connection the 88 incoming call was received from, use QDBusContext. 89 - QHostAddress will no longer convert IPv6 addresses of type "v4-mapped" 90 to IPv4. To perform this conversion manually, construct another 91 QHostAddress with the result of toIPv4Address(). 92 - (DY)LD_LIBRARY_PATH will no longer "stick" in the process environment 93 when starting a QProcess. This means that if a QProcess is started with 94 a clear environment, it will not specially inherit (DY)LD_LIBRARY_PATH 95 from the parent process. This should not affect most applications, but 96 if the old behavior is desired, one can simply pass a clear 97 QProcessEnvironment with the (DY)LD_LIBRARY_PATH values added, to the 98 QProcess. 99 - QAbstractTableModel and QAbstractListModel now reimplement sibling() 100 to avoid calling parent() (which returns a constant). Subclasses of 101 these models that override parent(), will likely also need to 102 override sibling() now. 103- Qt 5.5 received some header #include cleanups. Code that relied on indirect 104 includes from Qt headers may need to include some headers explicitly now. 105 For example, qstringlist.h no longer includes QDataStream and QObject. 106 107 - QCoreApplication: 108 * [QTBUG-30330][QTSOLBUG-184] On Windows, QCoreApplication::arguments() 109 now returns a list built from argv on Windows as well if a modified 110 argv was passed to the class' constructor. 111 112 - QIODevice: 113 * Opening Android assets with QIODevice::ReadWrite now returns false to 114 correctly indicate that the files are not writable. 115 116 - QItemDelegate: 117 * [QTBUG-3305] QItemDelegate will now not close a 118 QTextEdit/QPlainTextEdit editor when the tab key is pressed; instead, 119 the key will reach the editor. 120 121 - QProgressDialog: 122 * [QTBUG-17427][QTBUG-25316] The timer for estimating the duration of 123 the progress dialog is now started in the constructor and in 124 setValue(minimum()), as well as when calling setValue(0), as 125 previously documented. 126 127 - QSaveFile: 128 * [QTBUG-44086] Files created by QSaveFile do now have the same 129 rights as files created by QFile. This also fixes a regression in 130 QSettings: In the Qt 5.4 series, new files created by QSettings 131 were only readable by the current user. 132 133 - QVariant: 134 * [QTBUG-42722] QVariant now obeys the C++ type promotion rules when 135 comparing numeric types (integrals, float and double), including the 136 fact that unsigned comparisons are preferred for types of the same 137 rank (that is, now QVariant(-1) > QVariant(0U)). 138 139 - QWindow: 140 * QWindows will no longer be re-shown automatically when moved from a 141 destroyed QScreen, unless that QScreen was a virtual sibling of the 142 primary screen. 143 144 - qmake: 145 * For commercial builds, qmake now checks for a valid Qt license. This 146 requires setting up a Qt Account (or .qt-license file) on the 147 development machine. 148 * Qt configure and qmake used with a MinGW spec will no longer emulate 149 MSVC by picking up the INCLUDE and LIB environment variables. Use the 150 -I/-L configure options to pass additional paths, as you would under 151 Unix. 152 * A lot of quoting issues have been fixed. As a side effect, qmake 153 has become more sensitive to over-quoted file names in project 154 files. 155 * qmake is now stricter about syntax errors in project files. 156 157**************************************************************************** 158* Library * 159**************************************************************************** 160 161QtCore 162------ 163 164 - Added qEnvironmentVariableIntValue(). 165 - Added Q_DECL_RELAXED_CONSTEXPR for the corresponding C++14 feature 166 - Added qHashRange() and qHashRangeCommutative() functions to aid 167 implementing qHash() overloads for custom types. 168 - Q_ENUMS and Q_FLAGS have been deprecated, and replaced by Q_ENUM and 169 Q_FLAG macros. These two new macros automatically register the enum with 170 the Qt metatype system, allowing automatic conversion to or from string 171 in QVariant, or to show the strings by QDebug operators. They also 172 enable the new QMetaEnum::fromType function. 173 - QPersistentModel index becomes an built-in meta-type, including QVariant 174 support. 175 - Updated Unicode data to v.7.0 176 - Updated QLocale data to CLDR v.27 177 - Updated QTimeZone data to CLDR v.27 178 179 - Item Models: 180 * QItemSelectionModel can now be created without a model and have one 181 set later. 182 183 - Logging: 184 * QtInfoMsg got added as a new QtMsgType. Use the new qInfo(), qCInfo() 185 macros to log to it. 186 187 - Logging framework: 188 * %{threadid} now prints the real thread ID. On Linux, OS X, iOS, 189 FreeBSD and Windows, the value is unique system-wide. On other 190 systems, it will print something that may be process-specific (the 191 value of pthread_self(3)). To print the pointer to QThread::current(), 192 use %{qthreadptr}. 193 194 - moc 195 * Classes annotated with Q_GADGET can now have Q_PROPERTY and Q_INVOKABLE 196 functions. QMetaProperty::{read,write}OnGadget and 197 QMetaMethod::invokeOnGadget can be used with those. 198 199 - Objective-C: 200 * [QTBUG-37116] Added NSDate/CDateRef converters for QDateTime 201 202 - QAssociativeIterable: 203 * Added find(). 204 205 - QCommandLineParser: 206 * Message boxes are used to display errors and usage if no console 207 window can be obtained on Windows. 208 209 - QDebug: 210 * Printing of QStrings and QStringRefs whenever "noquote" is not active 211 now prints the strings in a format that can be copied back to C++ 212 code. All characters that aren't printable in US-ASCII are escaped 213 (this includes printable Unicode characters outside of US-ASCII). 214 Pretty-printing will not respect QTextFormat padding or field widths. 215 * Similarly, printing of QByteArrays whenever "noquote" is not active now 216 prints the arrays in a format consumable in C++, with all non-printable 217 characters printed in hex escape sequences. 218 219 - QJsonObject: 220 * Added conversion to and from QVariantHash 221 222 - QLibrary: 223 * Added DeepBindHint which maps to RTLD_DEEPBIND on Linux making it 224 possible to load libraries with external symbols that clash with 225 already loaded ones, such as plugins linked to Qt4. 226 227 - QLockFile: 228 * [QTBUG-45497] Detection of stale lock files got more robust and takes 229 the name of the process that belongs to the stored PID into account. 230 231 - QRegularExpression: 232 * Support for matching using QStringRef as the subject's string type has 233 been added. 234 235 - QSet: 236 * Can now be used as the key in QSet and QHash. 237 238 - QSortFilterProxyModel: 239 * [QTBUG-35440] QSortFilterProxyModel now properly forwards the roles 240 that have been changed when the source model emits dataChanged(). 241 242 - QStandardPaths: 243 * [QTBUG-38872][QTBUG-38845] Added QStandardPaths::AppConfigLocation, 244 for application-specific configuration directory. ConfigLocation was 245 inconsistent. 246 247 - QString: 248 * Added support for retrieving the QRegularExpressionMatch to indexOf 249 and lastIndexOf. 250 * Added QT_RESTRICTED_CAST_FROM_ASCII macro as less intrusive 251 alternative to QT_NO_CAST_FROM_ASCII. 252 * Added methods for convenient conversion to and from std::u16string and 253 std::u32string. 254 * Added asprintf(), vasprintf(). 255 256 - QThreadPool: 257 * Added QThreadPool::cancel() which allows removing from the job queue a 258 job that hasn't been started yet. 259 260 - QTimeZone: 261 * Added methods systemTimeZone() and utc() that return QTimeZone objects 262 for the system time zone and for UTC, respectively. 263 264 - QVector: 265 * Added QVector::append(const QVector &) overload 266 267 - QVector3D: 268 * Added convenience project and unproject methods to use like gluProject 269 and gluUnproject 270 271 - QtMath: 272 * qmath.h no longer includes math.h, so any sources depending on that 273 indirect inclusion may fail to build. 274 275 - State Machine: 276 * Added support for internal transitions. 277 * [QTBUG-40293] Added an addTransition() overload that takes a 278 pointer-to-member for the signal triggering the transition. 279 * [QTBUG-44963] Fixed an issue where a history state restore would 280 activate too many states, possibly putting the state machine in an 281 invalid state. 282 * QTBUG-44783] Fixed an issue where the state machine could end up in 283 an invalid state when transitions from a parallel state were not 284 checked for conflicts. 285 * Fixed a case where a parallel state was not exited and re-entered 286 when one of its substates was exited and subsequently re-entered. 287 * Fixed the non-deterministic behavior of picking a transition from a 288 set of conflicting transitions. 289 290QtDBus 291------ 292 293 - Added annotation org.qtproject.QtDBus.MethodName to allow 294 autogenerating C++ methods with different names to the original DBus 295 method 296 297QtGui 298----- 299 300 - Added support for device-specific backend plugins in eglfs. 301 - eglfs is now using fullscreen mode also when running on X11. 302 - Added a plugin to get mouse, keyboard and touch events via libinput. 303 - The linuxfb platform plugin's input device handling is now compatible 304 with eglfs. The evdev keyboard, mouse and touch code is compiled in by 305 default. 306 - The mouse cursor on Embedded Linux is now handling hotplugging correctly 307 with eglfs and linuxfb regardless of how the input handling code is 308 loaded (via a generic plugin or built in to the platform plugin). 309 - QOffscreenSurface is now relying on EGL_KHR_surfaceless_context when 310 available, and avoids creating a pbuffer surface when the extension is 311 present. 312 - initializeOpenGLFunctions() no longer needs to be called when querying a 313 versioned function wrapper object via QOpenGLContext::versionFunctions(). 314 - Added version function classes for OpenGL 4.4 and 4.5 and deprecate some 315 erroneously classified functions. 316 - Exposed TabFocusBehavior in QStyleHints 317 - [QTBUG-42240][QTBUG-43263] Qt now contains a built-in GPU driver 318 blacklist for Windows that disables the usage of desktop OpenGL with 319 some older cards that are known to be unstable with opengl32.dll. 320 - [QTBUG-44937] Support for QScreen::grabWindow() is now available on 321 embedded platforms (eglfs, linuxfb). 322 - Added QStyleHints::singleClickActivation to access whether the platform 323 expects item activation to occur on single clicks rather than double 324 clicks. 325 - [QTBUG-40034] QOpenGLWidget and QQuickWidget are now supported on iOS. 326 327 - Accessibility: 328 * [QTBUG-44479] Qt now reports text attributes correctly on Linux, so 329 ORCA+F now works properly in QTextEdit and other text controls. 330 331 - Accessibility / OS X: 332 * QTextEdit now properly reports to accessibility visual lines 333 (softlines) as lines, instead of whole paragraphs. This allows better 334 VoiceOver user experience when reading text line by line using arrows 335 up/down. 336 * Visual bounds returned by QTextEdit were singificantly improved; this 337 enables VoiceOver to draw properly positioned VoiceOver cursor. 338 339 - Image plugins: 340 * [QTBUG-37946][QTBUG-43563][QTBUG-45552][QTBUG-45865] An option has 341 been added to QImageReader to enable automatic application of EXIF 342 orientation. This behavior was default in Qt 5.4.1, but reverted in Qt 343 5.4.2. 344 345 - QFontDatabase: 346 * Added QFontDatabase::isPrivateFamily() 347 348 - QImage: 349 * Added support for grayscale and alpha 8-bit formats which can also be 350 rendered to. 351 352 - QPainter: 353 * [QTBUG-35830] QPainter will no longer try to replace IntersectClip 354 with ReplaceClip if the paint engine is a QPicture. 355 356 - QPlatformSurfaceEvent: 357 * [QTBUG-42476][QTBUG-42483] Added event class QPlatformSurfaceEvent, 358 which is sent to QWindow and QOffscreenSurface when native surface is 359 created or about to be destroyed. 360 361 - QQuaternion: 362 * Added methods to convert a quaternion to/from Euler angles and to/from 363 rotation matrix. 364 365 - QScreen: 366 * Added devicePixelRatio property. 367 368 - QTextDocument: 369 * Support for searching with a QRegularExpression in a document has been 370 added. 371 372 - QWheelEvent: 373 * On OSX, trackpad wheel event phase transitions now occur in the order 374 ScrollBegin, ScrollUpdate, ..., ScrollEnd, ScrollUpdate, ..., 375 ScrollEnd, where the second batch of updates represents momentum 376 events (inertial scrolling). 377 378 - QWindow: 379 * [QTBUG-32956] lastWindowClosed will now be emitted even if 380 quitOnLastWindowClosed is not set. 381 382 - Windows: 383 * [QTBUG-43263] Introduced experimental feature allowing the user to 384 specify a GPU driver buglist with some additional keywords to chooose 385 the GL renderer backend depending on GPU. 386 387 - i18n: 388 * [QTBUG-43447] Fixed bug where layout direction did not switch 389 according to the instruction in the translation file. 390 391 - Text: 392 * [QTBUG-39286] Fixed position of underline on centered text when the 393 text layout's width is an even number. 394 395QtNetwork 396--------- 397 398 - [QTBUG-26295] Introduced libproxy backend for Unix platforms, enabled 399 automatically if the required dev package is present 400 - As some legacy ifdefs for OpenSSL 0.9.7 and 0.9.8f were removed, Qt 401 will no longer build with these versions. In addition, there is no 402 longer support for an OpenSSL library built with NO_TLSEXT. 403 - [QTBUG-26538] Fixed a bug that caused both QTcpSocket and QUdpSocket to 404 close the socket and lose any bound ports before connecting. Now 405 bind()/setSocketDescriptor() followed by connect() will retain the 406 original file descriptor. 407 408 - QLocalSocket: 409 * [QTBUG-16688] On Windows, waitForReadyRead now always waits for more 410 data, even if bytes are still in the buffer. 411 412 - QNetworkAccessManager: 413 * It is now possible to use TLS PSK ciphersuites when using HTTPS (or 414 similar protocols working over SSL). 415 416 - QSslSocket: 417 * [QTBUG-39077] It is now possible to use TLS PSK ciphersuites in client 418 sockets. 419 * A new SSL backend for iOS and OS X, implemented with Apple's Secure 420 Transport (Security Framework). 421 422 - SSL/TLS support: 423 * [QTBUG-18972] It is now possible to parse elliptic curve certificates. 424 * It is now possible to choose which elliptic curves should be used by 425 an elliptic curve cipher. 426 427QtTest 428------ 429 430 - QCOMPARE now pretty-prints QSizePolicy{,::Policy,::ControlType{,s}}. 431 - QtTest now prints an escaped version of QByteArrays that failed to 432 compare with QCOMPARE, instead of the hex dump. 433 - QTest::toString() can now be overloaded (instead of just specialized) 434 for custom types, and is now reliably found through argument-dependent 435 lookup (ADL). 436 437QtWidgets 438--------- 439 440 - Added QPlainTextEdit::createStandardContextMenu(QPoint) overload that 441 takes the position in document coordinates. This method enables the 442 actions that are sensitive to the given position eg. where the user 443 clicked. 444 445 - Accessibility / OS X: 446 * VoiceOver users of QTextEdit can now use mouse and touch exploration 447 on trackpad to point at text to have spoken to them. 448 449 - Layouts: 450 * [QTBUG-43099] Fixed a bug where spans sometimes didn't distribute 451 themselves to the last cells they covered. 452 453 - QAbstractItemView: 454 * Added iconSizeChanged signal. 455 456 - QAbstractScrollArea: 457 * [QTBUG-8315] A getter for the viewport margins has been added. 458 459 - QComboBox: 460 * A QComboBox does not reset itself any more when setting the same model 461 more than once. 462 * [QTBUG-43350] QComboBox will now reset its root model index when a new 463 model is set on it. 464 465 - QHeaderView: 466 * [QTBUG-21201] Auto-scroll the view when making extended row/column 467 selections. 468 * Default section size is now style-dependent by default. 469 * Added resetDefaultSectionSize(). 470 471 - QMenu: 472 * [QTBUG-20094] QMenu now pick up how "sloppy" submenus behave from the 473 style. 474 475 - QOpenGLWidget: 476 * [QTBUG-40717] Added an UpdateBehavior flag to QOpenGLWidget and 477 enabled support for NoParitalUpdate for QOpenGLWidget. NoPartialUpdate 478 is the default update behavior for QOpenGLWidget. 479 480 - QSizePolicy: 481 * QSizePolicy::ControlTypes is now introspectable through QSizePolicy's 482 meta object. 483 484 - QToolButton: 485 * [QTBUG-23396] Fixed the double removal of ampersands. 486 487 - QTreeWidget: 488 * [QTBUG-40060] Restored Qt 5.1 behavior of QTreeWidgetItems with 489 ItemIsTristate to enable automatic management of the check state. 490 User-editable tristate checkboxes are now enabled by setting the new 491 flag ItemIsUserTristate. 492 493**************************************************************************** 494* Platform Specific Changes * 495**************************************************************************** 496 497 - Removed BlackBerry PlayBook support. 498 499Android 500------- 501 502 - [QTBUG-43705] Fixed canonical path for nonexistent paths on some 503 devices. 504 - [QTBUG-38700] On devices with translucent system UI, Qt's windows are now 505 positioned to avoid overlapping it. This behavior can be 506 overridden in the application's AndroidManifest.xml. 507 - [QTBUG-45430] Fixed a bug that caused applications not to be resumable 508 after user changed language in system settings. 509 510 - QtCore / QTimeZone: 511 * [QTBUG-35908] Android timezones are now available in QTimeZone. 512 513 - QtWidgets: 514 * Enable QDockWidget window decorations. 515 516 - The QtDBus module is now disabled by default. 517 518 - Added support for arm64-v8a, x86_64, and mips64 with gcc 4.9. 519 520OS X 521---- 522 523 - [QTBUG-43999] QApplication::setWindowIcon now changes the icon for the 524 application in the dock. 525 526 - Text: 527 * [QTBUG-44708] Fixed appending text with a different writing system and 528 formatting to a latin ligature. 529 530Windows 531------- 532 533 - QMimeData: 534 * [QTBUG-17373] Added support for handling dropping of multiple mail 535 attachments, adding ;index=N to the mimetype string 536 application/x-qt-windows-mime;value="FileContents" 537 538 - Text: 539 * [QTBUG-44501] Fixed design metrics for text 540 541X11/XCB 542------- 543 544 - GLX and EGL code paths are now dynamically resolved, making it possible 545 for one build of a plugin to use both code paths. The default is to use 546 the GLX code path if available. This can be overridden by specifying 547 QT_XCB_GL_INTEGRATION=xcb_egl as an environment variable. Enable the 548 logging category qt.xcb.glintegration.debug to get debug log output of 549 what integration is used. 550 - [QTBUG-31762] QSystemTrayIcon now uses StatusNotifier D-Bus protocol 551 when the desktop environment supports it 552 - [QTBUG-40174][QTBUG-42985] If all QScreens (xcb outputs) are 553 disconnected while an application is running, 554 QGuiApplication::primaryScreen() will now return null until a screen is 555 connected again. 556 557**************************************************************************** 558* Compiler Specific Changes * 559**************************************************************************** 560 561 - Qt 5.5 now unconditionally uses the "using" keyword. Compilers that do 562 not support this keyword are deprecated and will not be able to build 563 Qt. Previous versions of Qt may or may not compile, as no testing was 564 done to ensure it worked. 565 - Visual Studio: -Zm200 (an option to specify the precompiled header 566 memory allocation limit) is not added anymore by qmake to the compiler 567 calls. If you encounter an C1076 compiler error you might need to re-add 568 it in your .pro file. 569 570**************************************************************************** 571* Tools * 572**************************************************************************** 573 574configure & build system 575------------------------ 576 577 - Added support for VS2015. 578 - [QTBUG-31814][OS X/iOS] Qt is now built with a relative RPATH. 579 - [VS2012+] Qt is now always built with C++11 with these compilers. 580 - [Windows] Added -static-runtime option. 581 - Added support for GCC/Clang -fsanitize= options. 582 - Enabled tslib autodetection by default. 583 - Added configure-time check for IPC support. 584 - [QTBUG-44690][QNX] Fixed NEON detection when cross-compiling on Windows. 585 - On-device compilation should work better on RaspPi and some other 586 devices now (use linux-g++ mkspec). 587 - configure -redo and config.status support spaces in arguments now. 588 - Qt can be now built in and installed to directories with spaces. 589 Note that source directories with spaces are still not supported. 590 591qmake 592----- 593 594 - [QTBUG-3069][Linux] Building with -rpath will now create DT_RUNPATH tags 595 instead of DT_RPATH, allowing LD_LIBRARY_PATH to override the rpath. 596 - [QTBUG-41917][VS] Fixed project generation when PRECOMPILED_SOURCE is 597 in a different directory than PRECOMPILED_HEADER. 598 - [QTBUG-42454][MinGW] Added handling of QMAKE_MANIFEST. 599 - [QTBUG-13496][MSVC] CONFIG+=no_batch is now automatically added when 600 multiple sources with the same base name exist. 601 - Added $$[QT_INSTALL_PREFIX/dev], etc. properties which reflect the 602 on-device locations of Qt (the -prefix, etc. passed to configure). 603 - Building under MSys is less problematic now. 604 - [QTBUG-37269] Fixed cross-compilation for Unix on Windows/MinGW. 605 - [QTBUG-8202][QTBUG-20566][QTBUG-44685] Fixed distclean targets. 606 - [QTBUG-43162][VS] Added DISTFILES support for Visual Studio projects. 607 - [QTBUG-41753][VS][WinPhone] Fixed MdilXapCompile deployment step. 608 - [QTBUG-44960][VS] Reworked .dll deployment.
