STARS_6.3 is the latest version of the software package. It requires Excel 2007 or newer to be installed on your Windows PC (currently, it does not work with Excel for Mac). For older  versions of Excel use STARS_3.4; however it lacks the module that detects shifts in correlation coefficient. Please note that the software package (version 3.2), which is hosted on the Bering Climate website, has some bugs affecting the detection of regime shifts in variance. Those bugs are fixed in version 3.4.

Andrew Gartner converted STARS 2.1 from VBA to Matlab and Andrew Friedman made some minor changes to that Matlab code. Alistair Seddon implemented an R version of STARS (just for shifts in mean). Luca Stirnimann implemented the version 3.2 of STARS in R available on GitHub. Room at al (2022) wrote a manual on how to easily deploy STARS in R using the rshift package. The Python implementation of STARS (for shifts in mean only) is available on GitHub and an example of its application is presented here.

In addition to STARS, an Excel macro for the Iterated Cumulative Sums of Squares (ICSS) algorithm (Inclan and Tiao, 1994) is available for download below. ICSS is one of the most popular methods in econometrics for detecting change points in variance. It was used for comparison with STARS in Rodionov (2016).

Note that the first time you download the Excel file, the macros will be blocked by default in Microsoft 365. To unblock right-click the file and choose Properties from the context menu. At the bottom of the General tab, select the Unblock checkbox and select OK.
