New

Differential update of filter lists, as a result of discussions at AdguardTeam/FiltersCompiler#192. Resulting spec is here.

The goal is to NOT be ranked among the "most popular projects" by bandwidth usage (as per jsDelivr's public stats):

It is expected that differential updates will lower both requests and bandwidth usage.

IMPORTANT: To benefit the much shorter update period enabled by differential updates, you must let uBO auto-update the filter lists. Forcing a manual update will prevent differential updates until the next time a list auto-update.
