R 3.1.0 (codename “*Spring Dance*“) was released today!

You can get the source code from

https://cran.r-project.org/src/

or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course.

The full list of new features and bug fixes is provided below.

### Upgrading to R 3.1.0

You can download the latest version from here.

If you are using **Windows**, it might take another 24 hours until you could update R. For convenience, you can upgrade to the latest version of R using the installr package. Simply run the following code:

# installing/loading the latest installr package: install.packages("installr"); require(installr) #load / install+load installr updateR() |

After running “updateR()”, the function will detect that R is available for you, and will download+install it (etc.).

Note that the latest installr version (0.14.0) was released a week ago to CRAN, and it is recommended to upgrade to it, since it is now more robust for various extreme cases of upgrading R.

I try to keep the installr package updated and useful, so if you have any suggestions or remarks on the package – you are invited to leave a comment below.

If you use the global library system (as I do), you can run the following in the new version of R:
