/*! \page api_break Backwards Incompatible Changes
\tableofcontents
The API of QGIS libraries is allowed to be changed just between major versions of QGIS. For example, there
are various planned backwards incompatible changes between QGIS 1.8 and 2.0 because the version 2.0 is a new
major version. After a release of a major version of QGIS (e.g. 2.0) the developer team is committed to maintain
stable API for all subsequent minor releases (2.2, 2.4, ...). That roughly means we do not rename classes and methods,
remove them nor change their semantics. Existing code should keep working when the user updates QGIS
to another minor version (e.g. from 2.0 to 2.2), so all extensions of existing classes should be done in a manner that
third party developers do not need to adjust their code to work properly with newer QGIS releases.
Sometimes, however, we may need to break the API as a result of some code changes. These cases should be only exceptions
and they should happen only after consideration and agreement of the development team. Backwards incompatible changes
with too big impact should be deferred to a major version release.
This page tries to maintain a list with incompatible changes that happened in previous releases.
QGIS 3.0 {#qgis_api_break_3_0}
========
Version 3.0 brings changes to many underlying dependencies which QGIS is built upon. Any existing PyQGIS code will
need to be updated to address the changes made within these libraries.
Python 3.0
----------
QGIS 3.0 introduces a move to Python 3. This version brings many changes to both the Python language and individual Python
libraries. A good place to start learning about the changes involved, and how to port your code to Python 3, is available
in the official Python documentation: [Porting Python 2 Code to Python 3](https://docs.python.org/3/howto/pyporting.html).
Qt 5
----
QGIS 3.0 is based off version 5 of the underlying Qt libraries. Many changes and API breaks were introduced in Qt5. While
it is c++ specific, a good place to read about the major changes introduced in Qt5 is at the Qt docs:
[C++ API changes](http://doc.qt.io/qt-5/sourcebreaks.html)
PyQt 5
------
Together with the Python and Qt version changes, the PyQt libraries which expose Qt classes to Python have also had their
version bumped to PyQt 5. The changes introduced in PyQt 5 and the steps required to upgrade existing code are summarised at:
[Differences Between PyQt4 and PyQt5](http://pyqt.sourceforge.net/Docs/PyQt5/pyqt4_differences.html)

- QgsAttributeEditor was removed. Use QgsEditorWidgetRegistry::create() instead.
- Bezier3D.
- CloughTocherInterpolator.
- QgsColorbutton was removed. QgsColorButtonV2 has now been renamed to QgsColorButton. Hence, QgsColorButtonV2 does not exist anymore.
- QgsColorDialog was removed, and QgsColorDialogV2 was renamed to QgsColorDialog. Hence, QgsColorButtonV2 does not exist anymore.
All the functionality from the old QgsColorDialog has been moved to the new class.

General changes {#qgis_api_break_3_0_global}
---------------

- All destinationCRS() methods have been renamed to destinationCrs()
- All readXML() and _readXML() methods have been renamed to readXml() and _readXml()
- All writeXML() and _writeXML() methods have been renamed to writeXml() and _writeXml()
- All setLayerID() methods have been renamed to setLayerId()
- All layerID() methods have been renamed to layerId()

Labeling {#qgis_api_break_3_0_Labeling}
--------
Labeling of vector layers used to be configured in 2.x using setCustomProperties() method with various
lots of options prefixed with "labeling" keyword, for example: layer.setCustomProperties("labeling/fieldName", "my_field").
While 2.x projects and .qml files containing configuration using custom properties will still work,
calling these API methods will have no effect on layer's labeling configuration anymore: all settings
are now stored in objects derived from QgsAbstractVectorLayerLabeling:
- QgsVectorLayerSimpleLabeling - when all features are labeled the same way
- QgsRuleBasedLabeling - rule-based labeling
The current configuration of labeling can be queried with vector layer's labeling() method and modified with
setLabeling() method.
Data Providers {#qgis_api_break_3_0_DataProviders}
--------------
- Many methods in QgsDataProvider, QgsVectorDataProvider and QgsRasterDataProvider have been made const-correct.
This has no effect on PyQGIS code, but c++ code implementing third-party providers will need to update the
signatures of these methods to match. Affected methods are:
- QgsDataProvider: crs(), extent(), isValid(), supportsSubsetString(), subsetString()
- QgsVectorDataProvider: getFeatures(), minimumValue(), maximumValue(), uniqueValues(), enumValues(), defaultValue(),
attributeIndexes(), pkAttributeIndexes(), isSaveAndLoadStyleToDatabaseSupported()
- QgsRasterInterface: extent()
- Many protected member variables have been wrapped in setter/getter methods.
This should generally only affect 3rd party providers
- mCacheMinMaxDirty: use clearMinMaxCache()
- mNativeTypes: use setNativeTypes()
- mAttrPalIndexName: overwrite palAttributeIndexNames()
Qgis {#qgis_api_break_3_0_Qgis}
----
- The QGis class was renamed to Qgis for capitalization consistency with other class names
- permissiveToDouble() and permissiveToInt() where moved out of the QGis class and renamed to qgsPermissiveToDouble() and
qgsPermissiveToInt()
- The constants DEFAULT_IDENTIFY_RADIUS and MINIMUM_POINT_SIZE were removed

QGis::Kilometers, QGis::Yards, QGis::Miles and QGis::UnknownUnit have been moved to QgsUnitTypes::DistanceUnit.
Some of these unit types have also been renamed - see the notes on QgsUnitTypes below. All methods which accepted
QGis::UnitType parameters have been updated to take QgsUnitTypes::DistanceUnit instead.
- The unit handling methods toLiteral, fromLiteral, tr, fromTr, fromUnitToUnitFactor have been removed. Their
corresponding counterparts in QgsUnitTypes should be used instead.

- The enum QGis::GeometryType has been removed in favor of QgsWkbTypes::GeometryType
- singleType() has been removed. Use the equivalent QgsWkbTypes::singleType() instead

composerWillBeRemoved(), composerRemoved() were all removed. Composer windows are now only created
on demand, and destroyed when the window is closed. The new interface methods openComposers(),
openComposer(), closeComposer(), composerOpened(), composerWillBeClosed() and composerClosed()
are similar, but only apply to composer windows when they exist. To access all compositions
from a project, the new QgsProject.instance().layoutManager() class should be used instead.
Additionally, the new interface methods work with QgsComposerInterface objects instead
of QgsComposerView objects.
- interaction with the main window status bar should no longer use the native Qt statusBar() method.
Instead iface.statusBarIface() should be used.

- asGML2() was renamed to asGml2()
- asGML3() was renamed to asGml3()
- asJSON() was renamed to asJson()
- closestSegment() now returns an integer value for the leftOf test (-1 if point is to the left
of the geometry, +1 if the point is to the right of the geometry, or 0 for cases where left/right could not
be determined, e.g. point exactly on a line)
QgsActionManager {#qgis_api_break_3_0_QgsActionManager}

- `QgsActionManager::writeXml()` no longer takes a QDomDocument. The document is
extracted from the layerNode.
- `QgsActionManager::at()` has been removed. Use `QgsActionManager::action( id )`
to get an action by its UUID.

-------------------
- readXml() and writeXml() require a new argument: a reference to QgsReadWriteContext
QgsCoordinateReferenceSystem {#qgis_api_break_3_0_QgsCoordinateReferenceSystem}

- QgsCoordinateReferenceSystem now uses internal caches to avoid expensive database lookups
when CRS objects are initialized. This is handled internally, but invalidateCache() must be
called if changes are made to the CRS database.

not slots. The invalidTransformInput() signal has been removed.
- The extra QgsCoordinateTransform constructors (those not taking QgsCoordinateReferenceSystem arguments) have been
removed. Now, QgsCoordinateTransform must be created using an already existing source and destination
QgsCoordinateReferenceSystem object, and either a QgsCoordinateTransformContext object or a reference to the
current project instance.
- QgsCoordinateTransform::clone() has been removed. Just use direct copies instead.
- sourceCrs() and destCrs() now return a copy instead of a reference to the CRS. This has no effect on PyQGIS code, but c++

-------------------
- The constructor's doLoadFile parameter order has changed due to the addition of an inverted parameter
QgsCptCityColorRampDialog {#qgis_api_break_3_0_QgsCptCityColorRampDialog}
