 ### Coding Conventions
 
 * Classes are Uppercase, methods and functions lowerMixedCase.
-* We use a modified K&R Style, with 2-space tabs, inserting spaces for tabs.
-* Use meaningful variable names, e.g. `measurement` not `msm`.
+* Apart from those naming conventions, we adopt Google C++ style.
+* Use meaningful variable names, e.g. `measurement` not `msm`, avoid abbreviations.

 **Important Note**
 
-As of Dec 2021, the `develop` branch is officially in "Pre 4.2" mode. A great new feature we will be adding in 4.2 is *hybrid inference* a la DCSLAM (Kevin Doherty et al) and we envision several API-breaking changes will happen in the discrete folder.
+**As of January 2023, the `develop` branch is officially in "Pre 4.3" mode. We envision several API-breaking changes as we switch to C++17 and away from boost.**
 
-In addition, features deprecated in 4.1 will be removed. Please use the last [4.1.1 release](https://github.com/borglab/gtsam/releases/tag/4.1.1) if you need those features. However, most (not all, unfortunately) are easily converted and can be tracked down (in 4.1.1) by disabling the cmake flag `GTSAM_ALLOW_DEPRECATED_SINCE_V42`.
