 ### Automatic Differentiation
 
-`nimbleHMC` makes use of the automatic differentiation (AD) feature of `nimble`, which is currently available as a beta release.  See [nimble AD beta release](https://r-nimble.org/ad-beta) for more information about models and algorithms that make use of the AD features of `nimble`.
+`nimbleHMC` makes use of the automatic differentiation (AD) feature of `nimble`, which was released in `nimble` version 1.0.0.  See [Chapter 16: Automatic Derivatives](https://r-nimble.org/html_manual/cha-AD.html) of the Nimble User Manual for more information about the capabilities of the AD system, and how to use the AD system to calculate derivatives of functions written as `nimble` algorithms, as well as derivatives of model calculations.
