[!] added tm_circles (circles with fixed unit-based radii)
[!] added blend argument to all layers
[!] added hitbox to tm_lines and tm_symbols for view mode (so hovering and clicking also works well for small objects)
added tmap_mode_pool() to restrict which modes are cycled by ttm() and rtm(), e.g. library(tmap.mapgl); tmap_mode_pool(c("plot", "maplibre"))
shiny dispatch methods added (to allow integration for other modes)
added support for terra's PackedSpatX objects
added support for stars_proxy when changed after evaluation
tm_crs() can take bbox and tmaptools::bb arguments
added height to tmap_arrange (for interactive modes)
fixed date/time formatting of facet labels
bug fixes (most importantly regarding >=1000 polygons in view mode)

tmap 4.3

[!] support for PMTiles via new and experimental package tmap.sources
[!] tm_text: halo, shadow and background rectangles implemented in plot and view mode
[!] tm_scalebar: improved measurement (using ellipsoidal distance rather than Eucledian distances in projected crs)
crs handling improved: local crs accepted
tmap_save can also save in other modes (e.g. from tmap.mapgl)
fixed many view-mode/shiny related bugs

tmap 4.2

[!] improved legend (labeling #1174 and continuous-style intervals #1175)
[!] added tm_insets: inset maps, ggplot2 plots etc. excepted
[!] added tm_minimap for plot mode
improved animations (#1160)
tmap_overview added, which provides an overview of all map elements (layers and components)
tm_layout arguments limited to the useful ones
tm_components (was tm_comp_group) improved: now also applicable to map component functions
bbox added to tm_crs. Special value is "FULL" which refers to the whole earth

This fixes a few regressions in the tmap v4 release and adds improvements.

[!] basemaps in plot mode much sharper, added tmap_providers() (#1041, #1042)
[!] tm_comp_group() added to specify grouped components (incl legends)
[!] added tm_animate() (main use case: cartograms)
for the background and frame we introduce: bg/bg.color and frame/frame.color
tm_remove_layer() works again in Shiny (#1044)
tm_logo() works again in view mode (#1038).
few fixes in legend computing and size (#1039, #1032)
