 # development
+* Add Barreto et al 2023 (based on PALEO-PGEM, covering the last 5 M years),
+and all the WorldClim data (present, and future projections with multiple models
+and emission scenarios).
 * Improve `get_ice_mask()`, `get_land_mask()`, and `distance_from_sea()` to work
   on series rather than just on slices.
+* Speed up `region_*()` functions when subsetting the extent/cropping.
 
 # pastclim 1.2.4
 * Updates on how time is handled to stay in sync with changes in `terra`.

 # Download the data
 
 You will need to download climatic reconstructions before being able to
-do any real work with `pastclim`. Currently the library contains two
-datasets: *Beyer2020* which covers the last 120k years; and, for project
-that go further back in time, *Krapp2021* which goes back to 800kya. It
-is possible to add additional, custom datasets, but you will need some
-familiarity with handling `netcdf` files (see the vignette on 'custom
-dataset').
