- `spatSample<SpatRaster>` has new arguments `as.points` and `values`. Getting values, cells and coordinates is no longer mutually exclusive. In response to [#191] by Agustin Lobo
- `area<SpatRaster>` has a new argument `mask=FALSE`
- `classify` can now take a single number to request that many cuts
- `mosaic` and `merge` now warn and resample if rasters are not aligned
- `extract` has a new argument `exact` to get the fraction covered for each cell

## bug fixes

- `flip(x, direction="vertical")` no longer reverses the order of the layers
- `extract` did not work for horizontal or vertical lines as their extent was considered invalid. Reported by Monika Tomaszewska
- `autocor` did not handle NA values [#192] by Laurence Hawker
- `nearest` now works for angular coordinates
- The unit of `slope` in `terrain` was not correct (the tangent was returned instead of the slope), [#196] by Sven Alder
- `quantile` now works for rasters that have cells that are all `NA`. Reported by Jerry Nelson

## name changes

To avoid name conflicts with tidyverse 

with deprecation warning:

- separate -> segregate

- near -> nearby
- pack -> wrap 

without deprecation warning:

- transpose -> trans
- collapse -> tighten 
- fill -> fillHoles
- select -> sel
