Microsoft R Open (MRO), Microsoft's enhanced distribution of open source R, has been upgraded to version 3.4.3 and is now available for download for Windows, Mac, and Linux. This update upgrades the R language engine to the latest R (version 3.4.3) and updates the bundled packages (specifically: checkpoint, curl, doParallel, foreach, and iterators) to new versions.
MRO is 100% compatible with all R packages. MRO 3.4.3 points to a fixed CRAN snapshot taken on January 1 2018, and you can see some highlights of new packages released since the prior version of MRO on the Spotlights page. As always, you can use the built-in checkpoint package to access packages from an earlier date (for reproducibility) or a later date (to access new and updated packages).
MRO 3.4.3 is based on R 3.4.3, a minor update to the R engine (you can see the detailed list of updates to R here). This update is backwards-compatible with R 3.4.2 (and MRO 3.4.2), so you shouldn't encounter an new issues by upgrading.
