The problem

Seeing as https://github.com/ameshkov/diffupdates is now supported by uBlock Origin, I'm wondering when Adguard Home will support the same feature?

Especially because the standard seems to be written by an Adguard contributor. :)

Proposed solution

Support differential updates for blocklist sources.

Alternatives considered and additional information

This would also cause less CPU usage overall since when you update a list in this way, the whole list isn’t downloaded again

@talonric332, it would probably not, see https://github.com/AdguardTeam/AdGuardHome/issues/6540#issuecomment-1853770121. The only thing this feature would reduce is network usage, which may be beneficial for larger lists, but a new filtering engine must be compiled and replaced either way.
