I'm currently on Robohelp 2020 (2020.0.156) and need to update to the lastest version. What is the most recent version? I followed this thread (https://community.adobe.com/t5/robohelp-discussions/how-to-upgrade-robohelp/td-p/11765263) to the Downloads page, but the newest update I see on that page is Summer 2020 Release.
See the Announcements on this forum. It is explained that there was an update bug in 2020.0. It then explains how to update.
My site www.grainge.org includes many free Authoring and RoboHelp resources that may be of help.
On the Downloads page, click the "Summer 2020 Release" heading and it will expand to show you all the available patches (I've been confused. by that myself).
