Microsoft R Open 3.2.5 is now available for download. There are no changes of note in the R langauge engine with this release (R 3.2.5 was just a largely a version number increment).
There's lots new on the packages front though: Microsoft R Open 3.2.5 has a default CRAN snapshot date of May 1, 2016 and there was plenty of updates on CRAN in the month since MRO 3.2.4 was released. (As always, you can use the checkpoint package to access even newer package updates.) This releases' Package Spotlight notes new packages for deep learning, fuzzy joins for data frames, ggplot2 color themes inspired by scientific journals like The Lancet and TV shows like The Simpsons, calculating rolling statistics on time series, and for hexagonal-binning scatterplots for multi-class data (as shown below).
