+Hi,
+
+Version 0.9.1 of the 'catlearn' package is now available.
+
+Catlearn is an archive of thirteen formal models of categorization and
+learning. It's free and open source software ... and always will be. It has
+been downloaded 32,000 times.
+
+Version 0.9.1 is an upgrade release with two new models (Models 4 and 5 from
+Paskewitz & Jones, 2020), and (non-breaking) improvements to the Gluck & Bower
+(1988) implementation. 
+
+Catlearn is a package for R, and is very easy to install within that
+environment. Make sure you're running the latest version of R, and then type:
+
+install.packages('catlearn')
+
+and then
+
+library(catlearn).
+
+For a tutorial introduction to catlearn, and the Open Models initiative more
+generally, see Wills et al. (2017). There is also information here:
+
+https://andywills.info/catlearn
+
+Thanks to all the contributors to catlearn, and particular thanks to Lenard
+Dome who contributed new code for the version 0.9.1 release.
+
+All the best
+
