Is jamovi automatically updating?

Hello... I keep downloading the legacy version of jamovi (1.2.27.0) that I need to work with my operating system (Mac 10.12.6), and it works for me that day.

Switching undergrad class from SPSS... any advice?

Next semester I'm switching my undergraduate statistics courses to Jamovi after having used SPSS for many years. I'm in the process of converting my SPSS assignments, and I'm not anticipating much difficulty, but I thought that I'd solicit comments or advice from anyone who has made a similar change...
