A long time has passed since the last release. But we weren't sitting on our hands. We fixed a whole lot of various bugs, so most users will find something positive in this update. This version also contains some sweet additions that will be interesting mostly for rule creators.

[Improved] $important modifier was added to the rule constructor: #626

This one is a rather obvious: when you use the manual blocking tool to create a rule, you can now give this rule a higher priority by ticking the checkbox. The $important modifier was available before, but you had to manually add it via the user filter.

[Added] $csp modifier support: #685

This is strictly for the rule creators, as it requires the basic understanding of the Content Security Policy security layer.

This modifier completely changes the rule behaviour. If it is applied to a rule, it will not block the matching request. The response headers are going to be modified instead.

You can find the syntax and examples for csp inside the issue.
