The x13binary package takes the pain out of installing X-13ARIMA-SEATS by making it a fully resolved CRAN dependency. For example, if you install the excellent seasonal package by Christoph, then X-13ARIMA-SEATS will get pulled in via the x13binary package and things just work: Depend on x13binary and on all relevant OSs supported by R, you should have an X-13ARIMA-SEATS binary installed which will be called seamlessly by the higher-level packages such as seasonal or gunsales.
So now the full power of the what is likely the world's most sophisticated deseasonalization and forecasting package is now at your fingertips and the R prompt, just like any other of the 10,500+ CRAN packages.
Not many packaging changes in this release besides updating the underlying builds, but we switched our versioning scheme to reflect that our releases are driven by the US Census Bureau releases. But thanks to an initial contribution by David Schaub we now support the 'armhf' architecture common on Chromebooks running Linux.
