Microsoft R Open (MRO), Microsoft’s enhanced distribution of open source R, has been upgraded to version 3.3.3, and is now available for download for Windows, Mac, and Linux. This update upgrades the R language engine to R 3.3.3, upgrades the installer, and updates the bundled packages.
R 3.3.3 makes just a few minor fixes compared to R 3.3.2 (see the full list of changes here), so you shouldn’t encounter any compatibility issues when upgrading from MRO 3.3.2. For CRAN packages, MRO 3.3.3 points to CRAN snapshot taken on March 15, 2017 but as always, you can use the built-in checkpoint package to access packages from an earlier date (for compatibility) or a later date (to access new and updated packages).
