+Qt 5.12.2 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.12.0 through 5.12.1.
+For more details, refer to the online documentation included in this
+distribution. The documentation is also available online:
+The Qt version 5.12 series is binary compatible with the 5.11.x series.
+Applications compiled for 5.11 will continue to run with 5.12.
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:
+Each of these identifiers can be entered in the bug tracker to obtain more
+information about a particular change.
+* QtQml *
+ - Important Behavior Changes:
+ * The parameters passed to C++ functions from QML are now checked for
+ compatibility with the expected arguments. If they cannot be
+ converted, a warning is printed. In future versions of Qt a type error
+ will be thrown in JavaScript and the function will not be invoked.
+ * [QTBUG-73239] Removed revisions from the new Qt.labs.settings methods
+ and properties that were introduced in 5.12. Qt.labs plugins are
+ intended to always have revision 1.0 until they graduate.
+ - QQmlApplicationEngine:
+ * [QTBUG-73649] QQmlApplicationEngine connects quit() and exit() signals
+ with queued connections to avoid problems with AutoConnection, when
+ connecting to QCoreApplication slots.
+ - [QTBUG-69340] QML cache files are not unnecessarily re-generated.
+ - [QTBUG-71325] Fixed a crash in V4 string to number conversion on 32-bit
+ platforms.
+ - [QTBUG-72137] Fixed a crash in QML garbage collector when accessing
+ other items from Component.onDestruction.
+ - [QTBUG-72352] QML can be built with -no-feature-translation.
+ - [QTBUG-72407] We now annotate stack traces when frames are elided
+ through tail calls.
+ - [QTBUG-72734] Fixed a crash in the parser on certain kinds of bad input.
+ - [QTBUG-72858] Exception handlers are correctly scoped for try blocks and
+ for "for ... in" loops.
+ - [QTBUG-72908] QML can be built with -c++std=c++11 again.
+ - [QTBUG-72972] QQmlMetaType deletes attached properties in its destructor
+ to avoid a crash.
+ - [QTBUG-73009] Fixed a crash with
+ - [QTBUG-73013] If a signal sender is deleted during the handling of the
+ signal in QML, the QML engine won't crash anymore.
+ - [QTBUG-73152] Brought behavior of String.replace() in line with other
+ JS engines: "x".replace("x", "$1") gives "$1" in both JSC and V8, as there
+ are no captures that could be used as a replacement for $1. Two-digit
+ captures ($nm) get applied if $nm captures exist. If there are less than nm
+ but more than n captures available $n is replaced by the n'th capture and m
+ is copied over verbatim.
+ - [QTBUG-73425] Fixed allocation of large arrays at startup.
+ - [QTBUG-73733] Fixed an access-after-delete crash in DelegateModel.
+ - [QTBUG-73734] When a Q_GADGET type, marked as a primitive type with
+ Q_DECLARE_METATYPE, is emitted with a signal, it can now be accessed in QML.
+ - [QTBUG-73750] Fixed undefined Q_ENUM value in QML Connections object.
+ - [QTBUG-73821] Fixed a failing assert on 32bit platforms.
+ - The JIT compiler is disabled for the IPL32 (or X32) ABI. It did not work
+ before.
+ - The tail call optimization correctly counts method arguments on 32bit
+ platforms now.
+ - The JavaScript engine now tolerates UINT_MAX as array index.
+* QtQuick *
+ - TextInput/security:
+ * When the TextInput is used for password input, preallocate a buffer
+ for the string that stores the entered value and zero-out the string
+ on TextInput destruction to avoid leaking sensitive data to process
+ memory
+ - [QTBUG-63271] If a MouseArea sets itself invisible or disabled while
+ handling a mouse press, it does not acquire the exclusive grab
+ - [QTBUG-71887] TapHandler now consistently forgets touchpoints that occur
+ outside its parent's bounds. This eliminates the warning "pointId is
+ missing from current event, but was neither canceled nor released" when
+ tapping quickly and having some of the taps fall out of bounds.
+ (The warning still exists though, in case there are other scenarios where
+ Handlers remember "wanting" certain touchpoints and then they go missing.)
+ - [QTBUG-72822] PinchHandler now correctly holds its target in place when
+ axes are disabled.
+ - [QTBUG-71918] PointerHandlers are declared as direct children of
+ Flickable (ListView, TableView etc.) now get the pointer events properly.
+ - [QTBUG-42155] Canvas now handles switching between object and string
+ based colors
+ - [QTBUG-73113] Fixed a crash when reparenting QML Canvas items
+ - [QTBUG-73013] Fixed a crash in QuickView on setSource while deleting
+ the sender.
+ - [QT3DS-1419] Improved quality of Qt 3D Studio text labels.
