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: + +https://doc.qt.io/qt-5/index.html + +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: + +https://bugreports.qt.io/ + +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 qt.qml.binding.removal.info=true. + - [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. |
