version 0.2-1

st_as_sf uses date/time column names when appropriate
allow missing trailing comma's when subsetting: a[1,,] and a[1,] now do the same.
move rlang to Imports: ; rewrite subset using rlang.
add conversion to and from Spatial* classes, including the gridded ones, taking care of factor variables
depend on sf 0.7-2
add logz support for log-scale keys to plot and image

version 0.2-0

vignettes now use an external package, starsdata, for larger dataset examples
support [<-.stars e.g. to mask out values; support is.na.stars to replace NA masks
support cut methods and factor arrays (plot, subset); #56
add st_rasterize, which uses GDALRasterize to rasterize an sf object; #13
st_as_sf.stars now uses GDAL(F)Polygonize when give a regular or sheared grid grid cells are not points, and returns contour bands using GDALContourGenerateEx (requiring GDAL 2.4.0) in case cells are points; #13
support curvilinear grids; see #54 and the data_model vignette
add vignette about how stars_proxy objects work
stars_proxy objects defer processing of st_apply jobs until after subsampling; #50
allow reading sections of a raster, raster at a lower resolution, selected bands; #48
allow reading vectors (arrays) with more than 2^31 elements; #48
fold all higher dimensions into the third dimension before coercing to Raster; #40

add merge (merge attributes into array dimension) and split (split dimension over attributes)
interface to sf, raster and spacetime
improve plotting
handle logical arrays in plot
add st_apply, analogous to apply
add cropping/masking when used as x[buf] with buf an sf, sfc or bbox object; masking when x[buf, crop = FALSE]
add Ops (+,-,/ etc) and Math (sqrt, pow, sin etc) methods
add dimnames and dimnames<- methods for stars objects
downsample large grids to only plot pixels actually shown
can plot rectilinear grids (but will plot rgb images as regular grids)
rgb argument to image works
[ array-like subsetting works; first index is attribute selector
