JATOS/JATOS: JATOS v3.8.3 PRE-RELEASE

If you want to update a JATOS server from version < 3.7.1 read the release information from v3.7.x first.

Try out the new version on cortex.jatos.org.

• Bugfix: broken log-out (#291)

• Bugfixes
  • Result data exported as Plain Text missing line-breaks (#285 )
  • Malformed cookies from older JATOS versions can cause an InternalServerError with some browsers
• GUI:
  • Use browser's local date-time (instead of server's date-time) at e.g. Start Time or Last Seen in the result pages
  • Study Links, in the setup for the Personal types - add a button group to toggle between visibility of All, Active, Deactivated, and Used study links
• JATOS API: new endpoint to get the directory structure of a study assets directory in JSON
• A lot of administration improvements:
  • Abolished server-side cache -> all state is now either in the database or in cookies (easier to run JATOS on multiple nodes)
  • Logs config:
    • Allow to configure the location of the application logs
    • Allow logging to file or stdout
  • production.conf - Equalize property names. Most common names all start with jatos. now, but old-style names are still supported.
