This update adds several minor-ish (although filter enthusiasts will argue) features to the Filtering Log and improves ad blocking quality. You'll find an array of bug fixes, as usual.
[Added] Element hiding rules highlighting #1053
Applied element hiding rules are now highlighted with yellow color in the Filtering Log. This will greatly help parse log entries. We don't need to prove it to you if you are actively using it :)
[Added] Wildcard character support in rules with domain modifier #571
Again, another treat for filtering rules creators. Previously you had to list domains old-fashioned way: example.com,example.eu etc, and now you can simply use example.* syntax.
[Improved] Scripts are injected faster #1029
To efficiently block ads on the page we need a way to reliably inject our scripts before the in-page scripts are executed. A set of measures has been taken to ensure this. While there is still no 100% guarantee, the success chance has increased considerably — along with ad blocking quality.
