 # Changelog
 
+## [1.0.0] - 2021-11-15
+* `ggrastr` has gone through no major revisions in over a year. In order to avoid any confusion, this should be released with a major version.
+
 ## [0.2.3] - 2021-02-27
 * Function `rasterise()` changed to work with multiple layers
 * Function `rasterise()` now works with `geom_sf()`, i.e. should find any layers in a valid input list, and rasterize this.

 Package: ggrastr
 Type: Package
 Title: Rasterize Layers for 'ggplot2'
-Version: 0.2.3
+Version: 1.0.0
 Authors@R: c(person("Viktor", "Petukhov", email = "viktor.s.petukhov@ya.ru", role = c("aut", "cph")), person("Teun", "van den Brand", email = "t.vd.brand@nki.nl", role=c("aut")), person("Evan", "Biederstedt", email = "evan.biederstedt@gmail.com", role=c("cre", "aut")))
 Description: Rasterize only specific layers of a 'ggplot2' plot while simultaneously keeping all labels and text in vector format. This allows users to keep plots within the reasonable size limit without loosing vector properties of the scale-sensitive information.
