Announcing JASP 0.12

JASP 0.12.0 has been released and is now available on our download page.

DISCLAIMER:
In developing this new version, we recently ran into a persistent bug on Macbooks containing an Intel Iris GPU. This bug can cause JASP to crash. We are working on a solution for this issue, so for Mac users with an Intel Iris GPU: please be patient as we try and fix the issue. To mitigate the impact of this bug we have turned “safe graphics” on by default on all Macs. Because “safe graphics” slows down the interface, some users may wish to switch it off. To do so, go to Preferences -> Advanced and untick “Safe Graphics Mode”.

JASP 0.12 contains the following new features and improvements:

  • We have translated JASP to Dutch. To select Dutch, go to the menu, “Preferences”, “Interface”, and choose a language under “Preferred Language”. Switching languages immediately affects all of JASP: the input interface, the output tables and figures, and the help files. We are looking forward to translate JASP to other languages. Let us know if you’d like to contribute translating JASP to your own language!

    •  


     

  • Bayesian meta-analysis. In addition to the frequentist functionality, the meta-analysis module now also includes a Bayesian version (Gronau et al., 2017).

    •  


     

  • The JAGS module. The probabilistic programming language JAGS (Plummer, 2003) is now implemented in JASP as a GUI.
     


     

  • Distributions module. Visualize, simulate, fit, assess, and adapt: this module makes it easy to explore 12 popular distributions (i.e., Normal, Student’s t, F-distribution, Chi-squared, Beta, Gamma, Inverse gamma, Exponential, Bernoulli, Binomial, Negative binomial, and Poisson). Suggestions for other distributions? Let us know on our GitHub page!

    •  

     

  • Visual modeling module, including Flexplot.

    •  


     

  • Equivalence T-Tests module. JASP 0.12 includes not only frequentist but also Bayesian equivalence t-tests.
  • Improved output annotation. This version makes it much easier to format the text and adjust the background color.

    •  


     

  • Dark theme option. Instead of the bright JASP background, a dark background can be selected in the menu under “Preferences”, “Interface”, “Themes”.

    •  


     

 
In a series of upcoming blog posts we will showcase JASP’s new functionality in more detail. For a complete list of features and fixes, or to get started with JASP 0.12 right away, head over to our download page.

Final note: Apple is upgrading the security of MacOS. In order to adhere to Apple’s new security standards, existing software needs to be notarized, which may require substantial changes. JASP 0.12 complies with the new standards, but previous JASP versions do not, and hence these older versions will no longer work on Mojave and Catalina.
