The reason why this released is marked as Testing is that it brings several big changes.
Most visible of them is probably new Quick setter feature, which allows users to set all rules very quickly from Activity, Info view and other tools.
The other major improvement is not so visible, but not less important. We added weight system to Blocker rules, which gives users powerful tool to prioritize selected rules among others.
We tested all these new features intensively and they seem to work flawlessly, but if you find any issues, please, don't hesitate to contact us at firstname.lastname@example.org.
Blockrule is created.
