version 0.9.0

Add frac and weighted_frac summary operations, for summarizing categorical rasters
Add colname_fun argument to exact_extract, for controlling constructed column names
Add rasterize_polygons function to rasterize a polygon coverage, assigning cells to polygon with greatest coverage area

version 0.8.2

Fix incorrect read of raster values for value/weighting raster resolutions enabled in version 0.8.1

Fix incorrect grid compatibility error with certain value and weighting raster resolutions

Eagerly load more data into memory to provide better performance for suboptimally-chunked rasters
Add grid_compat_tol argument to exact_extract and relax from previously hardcoded default
Avoid error when include_area = TRUE and polygon does not intersect raster
Support terra SpatRaster inputs to coverage_fraction
Produce error instead of incorrect result when processing SpatRaster with duplicate names
Add coverage_area argument to exact_resample
Allow use of user-defined summary function in exact_resample
Allow multi-layer inputs to exact_resample

Fix incorrect coverage fraction calculated for certain sliver-shaped polygons with large coordinate values

Support terra SpatRaster inputs
Fix build using Windows/UTF-8 toolchain (Tomas Kalibera)
Improve performance of predefined summary operations on RasterStacks with many layers
Fix behavior of append_cols when summary function returns a multi-row data frame or vector of length > 1 for each feature

Fix Solaris build
Avoid undefined behavior when extracting values for polygon entirely outside raster extent
Fix incorrect results for GeometryCollections with more than one component (previously sf::st_cast was used to convert these to MultiPolygons, but st_cast only processes the first component.)

Fix bug causing progress bar to jump to 100%
Fix check for data frame in return from R function in exact_extract to allow for derived data frame types such as tibbles.

Add exact_resample
Add force_df and full_colnames arguments to exact_extract, to obtain output in a consistent format
Add include_cols and append_cols arguments to exact_extract for linking pixels values or summarized results to input features
Add median and quantile summary operations
Add stack_apply argument to exact_extract to apply an R function individually to each layer in a RasterStack / RasterBrick.
Support returning a data frame from an R function applied to each polygon, then combining those data frames with dplyr::bind_rows

Add named summary operations for variance, standard deviation, coefficient of variation
Improve performance, most dramatically for named summary operations on RasterStack or RasterBrick inputs.
Avoid floating point robustness error when computing stats on certain polygons using different resolution value and weighting rasters.

Add include_cell argument to exact_extract (Michael Sumner)
Fix error thrown by exact_extract when a polygon is partially outside the extent of the value raster but fully within the extent of the weighting raster.
Avoid error when processing polygons with a Z dimension on GEOS 3.6
Support sfc_GEOMETRY inputs if all features are polygonal

Fix incorrect results for some polygons that exactly follow boundaries of raster grid cells
Update tests for compatibility with sf >= 0.9.0

Add weighted mean and weighted sum operations to summarize one raster using the values of another (e.g., population-weighted mean temperature)
Support use of named summary options on RasterStack and RasterBrick inputs (reduces verbosity, improves performance)
Fix memory leak in CPP_coverage_fraction

Attempt to revert to static linking against GEOS if dynamic linking fails
Avoid undefined behavior when calling exact_extract on polygon that does not intersect raster.
