When reporting a bug you always have to specify “the context”, and that includes the branch. The context can be “captured” by simply taking a shot of the webconf’s dashboard.
Both, stable & testing branches can have bugs. Some of them are common, some others can be bugs already solved on testing , but not merged to stable yet (hotfixes). Finally there are new bugs introduced on testing. (@riban, should we add these 3 labels to the triage system?)
BTW, I would like to encourage people to take seriously the task of reporting a bug. Please, don’t forget to include the context and detailed steps to reproduce the bug. If we can’t reproduce the bug, normally we can’t solve it. By reporting correctly, you are saving time of developers, and we can concentrate on code instead of the github’s issue manager
Thanks,
