And rename to QgsUnitTypes::RenderUnits. This enum is used in
much more contexts than just symbols, so QgsUnitTypes is a
better fit for it.
All methods which previously accepted QgsSymbolV2::OutputUnit
parameters or QgsSymbolV2::OutputUnitList parameters now take
QgsUnitTypes::RenderUnit or QgsUnitTypes::RenderUnitList
parameters respectively.
This change consolidates more unit handling and conversion into
QgsUnitTypes.
Additionally, UnknownUnit was renamed to UnknownDistanceUnit.
All methods which accepted QGis::UnitType parameters have been
updated to take QgsUnitTypes::DistanceUnit instead.
ALso remove the unit handling methods toLiteral, fromLiteral, tr,
fromTr, and fromUnitToUnitFactor from QGis. Their corresponding
counterparts in QgsUnitTypes should be used instead.
for initializing CRS objects.
This avoids the need for the separate QgsCRSCache class,
and means that the caching benefits are available without the
need for calling methods from QgsCrsCache.
This avoids the need for
QgsCoordinateReferenceSystem crs;
crs.createFromSrsId(...)
and instead can be replaced with
QgsCoordinateReferenceSystem crs = QgsCoordinateReferenceSystem::fromSrsId(...)
The improvement allows immediate cancellation of raster rendering
in progress. Until now, even when map rendering got cancelled
(e.g. by zooming of panning canvas), the GUI got blocked while waiting
for raster layers to finish their rendering (only vector layers have
had support for cancellation). This should allow for much smoother
user experience while browsing maps including rasters.
The cancellation is supported currently by WMS/WMTS and WCS providers.
GDAL provider may also get support thanks to improvements in GDAL 2.

This adds the ability for users to set whether a user created
color scheme should show up in the color button drop-down menus.
It's accessed through the color picker dialog, on the lists tab.
Just add a new color scheme, then from the scheme menu tick the
new "show in buttons" option.
Handy if you have sets of common palettes and want them to be
instantly available through the color menu.
- rename methods with XML to Xml, CRS to Crs, WMS to Wms, ID to Id
- rename methods with SRS to Crs
- rename methods with abbreviations like "dest" to "destination"
- rename methods with abbreviations like "src" to "source"
Adds new methods overloads to QgsVectorLayer
getFeatures( expression )
getFeatures( ids )
getFeature( id )
These three methods to query features are by far the most used ones
and with this patch it is much easier to write and read code.
