+## New
+
+Differential update of filter lists, as a result of discussions at <https://github.com/AdguardTeam/FiltersCompiler/issues/192>. Resulting spec is [here](https://github.com/ameshkov/diffupdates).

+
+The goal is to **NOT** be ranked among the "most popular projects" by bandwidth usage (as per [jsDelivr's public stats](https://www.jsdelivr.com/statistics)):

+![jsDelivr stats](https://github.com/gorhill/uBlock/assets/585534/30a0522b-f9ff-4ff7-8902-6c78e0d61dd1)
+
+It is expected that differential updates will lower both requests and bandwidth usage.
+
+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.
+
