The mesh styling dialog now has new combo box for selection of resampling method for datesets defined on faces.
Also the analysis library has new class QgsMeshContours with export function for contour lines and contour polygons.
rendering operations on a specific feature are performed
This allows symbol layer subclasses to know when a set of rendering
operations all relate to a single feature, e.g. when a number
of polygons are rendered which all belong to the same multi-polygon
geometry attached to a single feature.
Without these hooks, symbol layer subclasses have no stable method
of knowing that these parts all relate to a single feature, or
have no means of knowing when the final part of that feature has
been rendered.
This commit adds a new fill symbol layer type "Random marker fill". It
allows polygon features to be rendered using a marker symbol placed
at random locations within the polygon boundary.
Options include:
- number of marker symbols to render for the polygon
- whether markers rendered near the edges of polygons should be clipped
to the polygon boundary or not
- an optional random number seed, to give consistent placement
of markers whenever maps are refreshed (also allows random placement
to play nice with QGIS server and tile-based rendering)

Allows raster nodata pixels to be colored in a specific (non-transparent) color.
Designed to match the "Display background value" option from ArcMap.

Fixes#26087
CRS validation, regardless of the user's settings
This avoids hacks put in place in other parts of QGIS code or in plugins
to temporarily deactivate the CRS validation prompt, providing a supported,
stable method to indicate that when loading a particular layer no CRS
validation is required.
This is a follow-up of https://github.com/qgis/QGIS/pull/31772
Driver de-registration is now defered after application restart to avoid
any risk of potential crashes if a dataset using a disabled driver was
already in use.
Adds an optimised c++ method for generating random points inside
a polygon geometry, using a tessellation based approach to
avoid the inefficiencies of the brute force filtered-random-points-within-extent
approach.
Speeds up project read time when these aren't needed, and also potentially
avoids issues caused by non-thread-safety in layouts (since some items rely
on classes which can only be used in the main thread e.g. QWebPage)
