In this release we've improved DNS proxy rules import and export.

You can now easily share your rules by long pressing on the IP or any group assigned to it.

When exporting an IP or group, the export format will now include information
about contained domains and how they are organised into groups.

Now you can also import rules from hosts files, coma and new-line separated lists and our own format (.adblock file extension).
You can import DNS rules into AdBlock from URL or directly from other apps like Files or Dropbox.

We've also improved the Safari Content Blocker with better rule handling and duplicate rule detection.
