[jsabater]

Please, when you have the chance, please check the compatibility with Redmine 5 and make the necessary adaptations, if any is needed. Thanks in advance.

@tofi86 any update plz

[jdehaan]

@tofi86 I did a cleanup and adapted for redmine 5. I did not test back on older pre-redmine 5 setups since I do not care at all on our side. The major thing is that we decided to get completely rid of the deface dependency. Basically there is no need to use deface at all since redmine provides adequate hooks in order to do the job in this case.

As the changes are pretty big let me know if you desire to take them partly I can then maybe provide small PRs one by one. If you feel like to take over parts by yourself, just go on. I made the changes by myself on my spare time, I am the author and it is
MIT licensed, so feel free to have a look and grasp what you consider being useful:
