 This ebook is based on the second edition of [Richard McElreath](https://twitter.com/rlmcelreath)'s [-@mcelreathStatisticalRethinkingBayesian2020] text, [*Statistical rethinking: A Bayesian course with examples in R and Stan*](https://xcelab.net/rm/statistical-rethinking/). My contributions show how to fit the models he covered with [Paul Bürkner](https://twitter.com/paulbuerkner)'s [**brms** package](https://github.com/paul-buerkner/brms) [@R-brms; @burknerBrmsPackageBayesian2017; @burknerAdvancedBayesianMultilevel2018], which makes it easy to fit Bayesian regression models in **R** [@R-base] using Hamiltonian Monte Carlo. I also prefer plotting and data wrangling with the packages from the [**tidyverse**](http://style.tidyverse.org) [@R-tidyverse; @wickhamWelcomeTidyverse2019]. So we'll be using those methods, too.

-After chipping away at mini releases of partial drafts, welcome to version 0.1.0! This is the first "full length" draft of this book. I say "full length" in quotes because although we have chapters corresponding to all the 17 chapters in McElreath's source material, some areas could use a little fleshing out. The sections I'm particularly anxious to improve are

+
+### Version 0.1.0. {-}
+
+I released the 0.1.0 version of this project in November 24, 2020. It was the first full-length and nearly complete draft including material from all the 17 chapters in McElreath's source material. All **brms** models were fit with version 2.14.0+. 
+
+### Version 0.1.1. {-}
+
+Welcome to version 0.1.1! This is a mini update designed to 
+
+* fix code breaks resulting from updates to the [**broom** package](https://CRAN.R-project.org/package=broom) [@R-broom], caught by [Jenny Bigman](https://twitter.com/jennybigman);
+* replace the soon-to-be retired `sample_n()` code with `slice_sample()`, caught by [Randall Pruim](https://github.com/rpruim);
+* and correct a few typos along the way.
+
+### We're not done yet and I could use your help. {-}
+
+Some areas of the book could use some fleshing out. The sections I'm particularly anxious to improve are
 
 * [4.6][~~Summary~~ B-splines with **brms**], which introduces the **brms** approach to b-splines;
 * [15.3][Categorical errors and discrete absences], which may someday include a **brms** workflow for categorical missing data;
 * [16.2.3][Coding the statistical model.], which contains a mixture model that McElreath fit directly in Stan and I suspect may be possible in **brms** with a custom likelihood; and
 * [16.4.2][The statistical model.], which contains an ordinary differential equation model that McElreath fit directly in Stan and I suspect may be possible in **brms**, but is beyond my current skill set.
