In looking through the Wiki on how to upgrade the application myself, I found a bad link. The sentence with "...download the latest openproject installer from http://bitnami.com/stack/openproject."
Though the text of the link is correct, when you click it you go to redmine instead.
The other issue with the documentation on Upgrading the application is that it is written to use the Bitnami installer. Unfortunately, the installer is at version 5.0.7 and the current version is 5.0.16.
I would much rather use the Bitnami installers as they simplify the process but when an application has a rapid release schedule I understand that it is not possible to always keep up with every point release. I feel a good compromise is providing good instructions for us users and believers in the Bitnami images and installers, on how to do the point updates ourselves.
