R 3.4.4 has been released, and binaries for Windows, Mac, Linux and now available for download on CRAN. This update (codenamed “Someone to Lean On” — likely a Peanuts reference, though I couldn't find which one with a quick search) is a minor bugfix release, and shouldn't cause any compatibility issues with scripts or packages written for prior versions of R in the 3.4.x series.
This update improves automatic timezone detection on some systems, and adds fixes for a some unusual corner cases in the statistics library. For a complete list of the changes, check the NEWS file for R 3.4.4 or follow the link below.
