Note that this list should be considered as work in progress until the first Beta release.
New Features (within existing modules)
- Qt 3D
- Improved profiling and troubleshooting support
- QSortPolicy add Uniform mode to control whether uniform minification needs to be performed or not
- QMouseDevice add updateAxesContinuously property
- OpenGL Renderer is now isolated as a plugin
- Qt Bluetooth
- Qt Core
- QFile::moveToTrash provides a cross platform API for moving files to the trash/recycling bin on Windows, macOS, and Linux desktop (implementing the freedesktop.org specification).
- QFileInfo::isJunction reports whether a file system entry is a Windows NTFS junction
- Qt GUI
- Qt Location
- Qt Multimedia

- Qt Network
- Qt QML
- Added qmlformat tool which automatically formats any QML file according to the QML Coding Conventions.
- Added support for the Nullish Coalescing Operator (??).
- Qt Quick
- Added a PathText type, which can be used together with Qt Quick Shapes to render text as geometry and not based on distance fields or pre-rendered textures. This can be useful for rendering large font sizes which would otherwise consume a lot of texture memory.
- Added Image.sourceClipRect to specify a clipping region, to request the image plugin to render a portion of an image source.
- Added cursorShape property to pointer handlers. Most pointer handlers (e.g. DragHandler) will change the cursor when the active state is true. HoverHandler will change it when the mouse is hovering over the Item that contains the HoverHandler.
- Qt Quick Controls 2
- Added HorizontalHeaderView and VerticalHeaderView to display header data in a TableView. Support flicking synchronization, and default, fusion, imagine, material, and universal delegate styles.
- Added selectTextByMouse property to ComboBox.
- Qt SerialBus
- Qt Test
- Qt Wayland Compositor
- Qt WebEngine
- Qt WebSockets
- Qt Widgets
- QDoc
- QDoc can now generate DocBook.
- QDoc now generates output for C++ class and function template parameters.
- QDoc now generates correct output for scoped enums (enum classes).
Platform Changes

- iOS
- Wayland

Deprecated Modules
To help preparing for the transition to Qt 6, numerous classes and member functions that will be removed from Qt 6.0 have been marked as deprecated in the Qt 5.15 release. Unless you define QT_NO_DEPRECATED_WARNINGS in your project, you will get compiler warnings for code that uses any deprecated APIs. Those warnings will explain which API to use instead. To disable any deprecated APIs completely, use the QT_DISABLE_DEPRECATED_BEFORE macro.
The following modules are part of Qt 5.15 release, but deprecated and considered for removal in subsequent releases of Qt:
- Qt Script
- Qt Quick Controls 1
- Qt XmlPatterns
Removed Modules
The following modules have been deprecated earlier and no longer part of the Qt 5.15 release:
