+# `hystar` development version
+
+# `hystar` 1.2.0
+
+* More options to customize the graphs from the `plot()`-method for R-objects of class `hystar_fit` and `hystar_sim`:
+
+  - the colors of the background and lines
+
+  - line types and widths of `z`, `y` and the thresholds
+
+* More default arguments in `z_sim`: `n_t = 100` and `n_switches = 2`. Now, all arguments have a default, which allows you to create examples faster.
+
+* More default arguments in `hystar_sim`: `r = c(-0.5, 0.5)`, `d = 0`, `phi_R0 = c(0, 0.5)` and `phi_R1 = c(2, 0.5)`. Now, the only necessary argument is `z`.
+
+# `hystar` 1.1.0
+
+* Fixed a mistake in the estimation of the asymptotic standard error. I noticed this during simulations, where some confidence interval coverage rates were strikingly low. All is fine now!
+
+# `hystar` 1.0.0
+
+* First CRAN release!
