## Be aware that R has a consistent release schedule. Every four months a new version of R is released, fixing _bugs_ and implementing new solutions. There are two main types of releases, _major_ and _minor_. For example, today, 2021-02-24, the latest version of R is 4.0.4. The first digit ("4") indicates the _major_ release while all others are of the _minor_ type. Generally, the _minor_ changes are very specific and, possibly, will have little impact on your work.

## 
## However, unlike _minor_ releases, **_major_ releases are fully reflected in the R package ecosystem**. Every time you install a new _major_ version of R, you will have to reinstall all packages. Particularly, the problem here is that it is not uncommon that a new major release comes with package incompatibility issues. My advice is: every time a new _major_ release of R comes out, **wait a few months** before installing it on your machine. Thus, the authors of the packages will have more time to update their codes, minimizing the possibility of compatibility problems.
