# swephR v0.2.1

This morning swephR version 0.2.1 made it unto CRAN and is now propagating to the mirrors.

The goal of swephR is to provide an R interface to the Swiss Ephemeris, a high precision ephemeris based upon the DE431 ephemeris from NASA’s JPL. It covers the time range 13201 BCE to 17191 CE.

This new version comes closely after last week’s release and contains only a single albeit important fix to a stack overflow write found by the UBSAN tests done on CRAN. Sadly I did not find this error using rhub::check_with_sanitizers() before uploading to CRAN. I will analyze this further before the next upload, since I fear that other issues like this might surface as we expose more of the Swiss Ephemeris to R.
