Qt 5.12.4 release provides a number of bug fixes, as well as performance and other improvements. As an important new item it provides binaries build with OpenSSL 1.1.1, including the new TLS 1.3 functionality.
Qt 5.12.3, the third patch release of Qt 5.12 LTS, is released today. While not adding new features, the Qt 5.12.3 release provides a number of bug fixes, as well as performance and other improvements.
Compared to Qt 5.12.2, the new Qt 5.12.3 provides almost 200 bug fixes. For details of the most important changes, please check the Change files of Qt 5.12.3.
Qt 5.12 LTS will receive many more patch releases throughout the coming years and we recommend all active developed projects to migrate to Qt 5.12 LTS. Qt 5.9 LTS is currently in ‘Strict’ phase and receives only the selected important bug and security fixes, while Qt 5.12 LTS is currently receiving all the bug fixes. Qt 5.6 Support has ended in March 2019, so all active projects still using Qt 5.6 LTS should migrate to a later version of Qt.

Just in time for the end of the year, we have released Qt 5.12 LTS today. This is a long-term-supported (LTS) release that we will support for 3 years to come. We have had a strong focus on quality and fixed more than 2000 bugs since the last Qt LTS version, Qt 5.9.7 – make that over 5000 bugfixes since Qt 5.6.3. Of course, this is only the start, and we will work hard on continuously improving the quality of Qt 5.12 in upcoming patches

Qt Bluetooth
Bluetooth Low Energy API final release (5.4 was featuring tech preview).
Bluetooth Low Energy Support for Android (requires Android v18+) added.
Bluetooth Classic and Low Energy support for iOS and OS X.
Qt Core
You can now have Q_PROPERTY and Q_INVOKABLE within a Q_GADGET, and there is a way to query the QMetaObject of such gadget using the QMetaTYpe system.
Added Q_ENUM to replace Q_ENUMS which allow to get a QMetaEnum at compile time using QMetaEnum::fromType<T>. Such enums are now automatically registered as metatype, and can be converted to string within QVariant, or are printed as string by qDebug()
Qt GUI
Windows packages are all built with -opengl dynamic. No OpenGL-only or ANGLE-only builds are provided anymore.
On Windows the OpenGL implementation to use can now be configured based on the GPU vendor and driver version using JSON configuration files. This allows shipping fine-grained card and driver blacklists with the apps, when necessary.
QOpenGLWidget is now supported in iOS.
QImage: 8-bit alpha map and grayscale formats.
QImageReader: EXIF orientation can now be read though the transformation method, and applied on read to JPEGs if wanted.
Qt Multimedia
GStreamer 1.0 support. Note that the default is still 0.10. 1.0 support can be enabled by configuring Qt with '-gstreamer 1.0'.
New video filtering framework to integrate frameworks like OpenCV or compute APIs such as OpenCL or CUDA with VideoOutput elements.
New API to control camera viewfinder settings
Improved camera support on iOS (focus, zoom, exposure, viewfinder/image settings)
The QML MediaPlayer is now rendered in an OpenGL texture on iOS. This means VideoOutput supports advanced transformation, shader effects and doesn't have to be always on top of other items anymore.
Qt NFC
Neard based backend for Linux added.
Qt Network
New SSL back-end for iOS and OS X based on Secure Transport. Note that in Qt 5.6 this will become the default SSL: back-end on these platforms.
Support for libproxy
Support for TLS PSK ciphersuites
Support for elliptic curve certificates
Ability to select specific curves when using elliptic curve ciphersuites.
QPA
Added support for the Raspberry Pi 2.
Added support for the ODROID-XU3.
On supported desktops, the xcb plugin now uses the D-Bus based org.kde.StatusNotifier protocol for system tray icons, and org.freedesktop.Notifications for notifications.
KMS/DRM backend for EGLFS. This replaces the now deprecated KMS platform plugin. It allows running apps with eglfs on the console on systems with Mesa and devices that come with drm support.
EGLFS has a plugin-based backend mechanism in addition to the existing, statically compiled-in solution. Most compiled-in hooks are converted to be dynamically loaded plugins that are built based on configure time tests. This reduces the reliance on the device makespecs for RPi, i.MX6 and Mali-based devices.
Input handling is now unified for EGLFS and LinuxFB, avoiding the need to launch and configure LinuxFB-based apps differently than when using EGLFS.
tslib is now better integrated with EGLFS and LinuxFB to provide support for resistive single-touch touchscreens often used in industrial environments.
xcb is refactored to move GLX and EGL support into plugins. No more ifdefs, allowing building both backends.
Added a TUIO Touch plugin for receiving remote touch events via UDP.
Added a libinput plugin.
iOS: you can now use QFileDialog to browse system photos using a native image picker dialog by setting directory to QStandardPaths::PicturesLocation. Selected photos can be loaded using QFile.
Qt QML
It is now possible to conveniently expose custom C++ value types into the JavaScript environment of QML and QJSEngine.
Support for JavaScript typed arrays
Various performance improvements, notably QJSValue
Added convenience qJsEngine(QObject*) getter function.
Qt Quick
Windows now defaults to the threaded Qt Quick render loop when using desktop OpenGL (opengl32.dll).
QQuickWidget is now supported in iOS.
QQuickRenderControl supports threaded rendering.
Improved behavior of Flickable on OS X trackpads using pixel deltas from native gestures.
PinchArea handles native pinch gestures when the OS provides them (so far only on OS X). Otherwise it relies on touch events, as before.
Added a smart zoom signal to PinchArea to react to that gesture on an OS X trackpad.
MouseArea now has a scrollGestureEnabled property to control whether native scroll gestures from the OS will be handled by the wheel signal handler.
Qt Quick Controls
Qt Quick Extras (formerly Qt Quick Enterprise Controls) was added under the QtQuick.Extras import.
TreeView control for QAbstractItemModel-derived models. Supports QItemSelectionModel selection.
Qt WebEngine
Updated Chromium snapshot to version 40
WebEngineProfile for control of storage and cache paths and related policies.
Added support for javascript Geolocation API with QtLocation as a backend
Added API for managing downloading of files
Added API for controlling cache and cookie paths and policy
Added API for WebEngine settings
Added API for injecting user scripts
Various experimental QML API has been promoted to public
Added QtWebChannel integration API over Chromium IPC
Qt WebView
Added native implementations for Mac OS X.
Added API for running JavaScript (Requires API 19+ on Android).
Added API for setting the HTML content.
Added API for load status notifications.
Chromium-based browser engine Qt WebEngine
Qt WebView for showing web content using the native OS web engine on mobile
Full support on Qt for Windows Store Apps, including WinRT and Windows Phone 8.1
Improved Compliance with iOS 8 and Xcode 6
Improved OS X 10.10 ‘Yosemite’ support and new Mac AppStore signing
High-DPI support for Windows and OS X
Dynamic GL switching between OpenGL and ANGLE on Windows
Mix OpenGL and Qt Quick with QOpenGLWidget
Android Look-and-Feel for Qt Quick Controls
