The download of Platform Server 18.104.22.168 was made available yesterday (15th July).
However, the previous version was 9.1.501.
Am I missing something?
The latest available version of OutSystems Platform is 9.1.501.0 (https://www.outsystems.com/home/downloads/).
However, version 9.0 is still being maintained and the Platform Server patch 22.214.171.124 is for this older version. The installation packages for older OutSystems Platform versions are available here: http://www.outsystems.com/home/downloads/88/
Ahhh. My bad.
