-* Updated minimal requirements (@sebastianueckert, #208)
+* Updated minimal requirements for `readr` (>= 2.1.0) (@sebastianueckert, #208)
+* Updated minimal requirments for R (>= 3.5.0) `because serialized objects in serialize/load version 3 cannot be read in older versions of R`
 * Don't summarize RANMETHOD as an estimation method (@vrognas, #213)
 * Fix bug when a given estimation method is used several time in a single `$PROBLEM`. Sequential `$ESTIMATION` are now each attributed different `subprob` visible to the user using `list_files(xpdb)` (@vrognas, #213)
 * Compatibility fix with ggplot2 3.4.0, all layers but `geom_point` and `geom_text` should now use `linewidth` instead of `size` for line width.
