Qt 5.11 introduces many new features and improvements as well as bugfixes
over the 5.10.x series. For more details, refer to the online documentation
included in this distribution. The documentation is also available online:
http://doc.qt.io/qt-5/index.html
The Qt version 5.11 series is binary compatible with the 5.10.x series.
Applications compiled for 5.10 will continue to run with 5.11.
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.
****************************************************************************
* Qt 5.11.0 Changes *
****************************************************************************
QtLocation
----------
- Qt.labs.location
* A new experimental QML plugin introduced, Qt.labs.location, which
offers two new categories of QML elements: Map Objects and the
Navigator type. Both are experimental, not supposed to work in every
setup (check documentation). This plugin can be disabled at configure
time, through the location-labs-plugin feature.
* Map objects are supposed to be QQuickItem-less equivalents of
Map Items. They are supposed to be easy to implement in plugins, and
to introduce minimal overhead. They come with a reference
implementation based on QSGNodes, that is supposed to work in all of the
currently offered raster based plugins.
At the present, the MapboxGL plugin does not offer map objects support.
* The Navigator type is a new QML api to expose turn-by-turn navigation
functions present in plugins. It requires a plugin supporting
one of the Navigation capabilities to actually work.
At the present, none of the open source plugins have these capabilities.
- MapParameter
* MapParameter type now deprecated and re-registered under the DynamicParameter
name.
- QGeoServiceProvider/QGeoServiceProviderFactory
* Added QGeoServiceProviderFactoryV2, capable of producing
QNavigationManagerEngine objects.
Note: QNavigationManagerEngine is private API.
- QGeoPath
* The path property changed type, from QList<QGeoCoordinate> to
QVariantList. This is binary-compatible with the previous release,
and source-compatible in QML.
It may, however, introduce source incompatibilities when using
the QObject property API in C++ (::property and ::setProperty), for
example in the generation of language bindings.
For the regular user-code, the use case was deemed as rare enough
(since QGeoShape has a public setter/getter for the path) to not cause
any problem.
As the beta phase passed without issues, this change was therefore left in place.
- QGeoRoute
* QGeoRoute, QGeoRouteSegment and QGeoManeuver private implementation are
now (privately) exported and can be subclassed in plugins to provide
custom private implementations.
* QGeoRouteRequest now allows to specify extra parameters in QVariantMap form.
* RouteQuery (QDeclarativeGeoRouteQuery) now allows to specify extra parameters
through Map/DynamicParameters.
* Added extended attributes to QGeoManeuver/QDeclarativeGeoManeuver.
* [QTBUG-64066] Introduced new Waypoint QML type, intended to replace
QGeoCoordinate as mean to specify waypoints in a RouteQuery.
- QPlace
* QPlace private implementation is now (privately) exported and can be
subclassed in plugins to provide custom private implementations.
* QPlaceContent::Type has a new value, CustomType.
- QDeclarativeGeoMap
* [QTBUG-66315] Fixed a crash calling Map.clearMapItems before Map is
initialized.
* Fixed MapGestureArea not emitting when controlled with scroll wheel.
* [QTBUG-66880] Fixed clearData not triggering scene update.
* [QTBUG-67580] Fixed crash in QQuickGeoMapGestureArea.
* [QTBUG-67759] Fixed crash when calling clearData at startup.
- Map Items
* [QTBUG-66758] Fixed re-set map items rendering stale geometry.
* [QTBUG-38459] Fixed the geometry of map items so that, if layers.enabled
is set to true, the scene graph renderer will not cut the items borders
anymore.
* [QTBUG-66692, QTBUG-66830] Fixed polyline geometry generation.
* [QTBUG-62086, QTBUG-65833] Fixed MapItemView not setting context data
upon item deletion.
* [QTBUG-67765] Fixed interaction with Map Items borders.
- Plugins
* Mapbox: Added OnlinePlacesFeature, PlaceRecommendationsFeature, SearchSuggestionsFeature
and LocalizedPlacesFeature.
* Mapbox: Added OnlineGeocodingFeature, ReverseGeocodingFeature and LocalizedGeocodingFeature.
* Mapbox/OSM: OSRM backend now returns extended attributes for the maneuvers, such as
bearing_before, bearing_after, instruction, type and modifier.
* Mapbox/OSM: OSRM backend now uses Waypoint's bearing when sending a route request.
* Mapbox/OSM: Added OSRM's {leg,step}_index extra attribute to QGeoManeuver.
* Mapbox: Supported Mapbox Directions API voice & banner instructions.
* MapboxGL: Added map margins support via 'margins' map parameter.
* HERE: the plugin now uses Waypoint's bearing when sending a route request.
* OSM: supported the query limit parameter in the nominatim backend.
QtPositioning
----------
* [QTBUG-65937] Metatype for QGeoPositionInfo is now declared and registered.
This change introduces a potential source incompatibility, as existing user code may
contain the type registration already.
