If you haven’t heard, there are a few KDE projects testing Phabricator for patch review and project management.
KActivities are amongst those.
So, from now on, if you want to provide patches, you are advised to do that through http://phabricator.kde.org/ and the Arcanist tool instead of the ReviewBoard.
We are also going to organize our work tasks on Phabricator instead of todo.kde.org.
The ultimate goal is to test whether Phabricator is a viable alternative to a few of our services.
The ReviewBoard is still working, but if you do send patches there, please also ping me on IRC, or send me an email since it is easy to miss those mails.
