 # stochtree 0.1.0
 
-* Initial CRAN submission.
+* Initial release on CRAN.
+* Support for sampling stochastic tree ensembles using two algorithms: MCMC and Grow-From-Root (GFR)
+* High-level model types supported:
+    * Supervised learning with constant leaves or user-specified leaf regression models
+    * Causal effect estimation with binary, continuous, or multivariate treatments
+* Additional high-level modeling features:
+    * Forest-based variance function estimation (heteroskedasticity)
+    * Additive (univariate or multivariate) group random effects
+    * Multi-chain sampling and support for parallelism
+    * "Warm-start" initialization of MCMC forest samplers via the Grow-From-Root (GFR) algorithm
+    * Automated preprocessing / handling of categorical variables
+* Low-level interface:
+    * Ability to combine a forest sampler with other (additive) model terms, without using C++
+    * Combine and sample an arbitrary number of forests or random effects terms
